WARNINGS
Included as part of the "PRECAUTIONS" Section
PRECAUTIONS
Life-Threatening Respiratory Depression
Serious, life-threatening, or fatal respiratory depression has been reported with the use of opioids,
even when used as recommended. Respiratory depression, if not immediately recognized and treated,
may lead to respiratory arrest and death. Management of respiratory depression may include close
observation, supportive measures, and use of opioid antagonists, depending on the patient’s clinical
status [see OVERDOSE]. Carbon dioxide (CO ) retention from opioid-induced respiratory
depression can exacerbate the sedating effects of opioids.
While serious, life-threatening, or fatal respiratory depression can occur at any time during the use of
ACTIQ, the risk is greatest during the initiation of therapy or following a dosage increase. Monitor
patients closely for respiratory depression, especially within the first 24-72 hours of initiating therapy
with and following dosage increases of ACTIQ.
To reduce the risk of respiratory depression, proper dosing and titration of ACTIQ are essential [see DOSAGE AND ADMINISTRATION]. Overestimating the ACTIQ dosage can result in a fatal overdose with
the first dose. The substitution of ACTIQ for any other fentanyl product may result in fatal overdose
[see Risk Of Medication Errors].
ACTIQ Could Be Fatal To Individuals For Whom It Is Not Prescribed And For Those Who Are Not Opioidtolerant.
Accidental ingestion of even one dose of ACTIQ, especially by children, can result in respiratory
depression and death due to an overdose of fentanyl [see Life-Threatening Respiratory Depression, Increased Risk Of Overdose In Children Due To Accidental Ingestion Or Exposure].
Increased Risk Of Overdose In Children Due To Accidental Ingestion Or Exposure
Death has been reported in children who have accidentally ingested ACTIQ.
Patients and their caregivers must be informed that ACTIQ contains a medicine in an amount which can
be fatal to a child. Healthcare providers and dispensing pharmacists must specifically question patients
or caregivers about the presence of children in the home (on a full time or visiting basis) and counsel
them regarding the dangers to children from inadvertent exposure.
Patients and their caregivers must be instructed to keep both used and unused dosage units out of the
reach of children. While all units should be disposed of immediately after use, partially consumed units
represent a special risk to children. In the event that a unit is not completely consumed it must be
properly disposed as soon as possible [see PATIENT INFORMATION] .
Detailed instructions for the proper storage, administration, disposal, and important instructions for
managing an overdose of ACTIQ are provided in the ACTIQ Medication Guide. Encourage patients to
read this information in its entirety and give them an opportunity to have their questions answered.
Risks Of Concomitant Use Or Discontinuation Of Cytochrome P450 3A4 Inhibitors And
Inducers
Concomitant use of ACTIQ with a CYP3A4 inhibitor, such as macrolide antibiotics (e.g.,
erythromycin), azole-antifungal agents (e.g., ketoconazole), and protease inhibitors (e.g., ritonavir), may
increase plasma concentrations of fentanyl and prolong opioid adverse reactions, which may cause
potentially fatal respiratory depression [seeLife-Threatening Respiratory Depression], particularly when an
inhibitor is added after a stable dose of ACTIQ is achieved. Similarly, discontinuation of a CYP3A4
inducer, such as rifampin, carbamazepine, and phenytoin, in ACTIQ-treated patients may increase
fentanyl plasma concentrations and prolong opioid adverse reactions. When using ACTIQ with
CYP3A4 inhibitors or discontinuing CYP3A4 inducers in ACTIQ-treated patients, monitor patients
closely at frequent intervals and consider dosage reduction of ACTIQ until stable drug effects are
achieved [see DRUG INTERACTIONS].
Concomitant use of ACTIQ with CYP3A4 inducers or discontinuation of a CYP3A4 inhibitor could
decrease fentanyl plasma concentrations, decrease opioid efficacy or, possibly, lead to a withdrawal
syndrome in a patient who had developed physical dependence to fentanyl. When using ACTIQ with
CYP3A4 inducers or discontinuing CYP3A4 inhibitors, monitor patients closely at frequent intervals
and consider increasing the opioid dosage if needed to maintain adequate analgesia or if symptoms of
opioid withdrawal occur [see DRUG INTERACTIONS].
Risks From Concomitant Use With Benzodiazepines Or Other CNS Depressants (Including
Alcohol)
Profound sedation, respiratory depression, coma, and death may result from the concomitant use of
ACTIQ with benzodiazepines or other CNS depressants (e.g., non-benzodiazepine sedatives/hypnotics,
anxiolytics, tranquilizers, muscle relaxants, general anesthetics, antipsychotics, other opioids, alcohol).
Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom
alternative treatment options are inadequate.
Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines
increases the risk of drug-related mortality compared to use of opioid analgesics alone. Because of
similar pharmacological properties, it is reasonable to expect similar risk with the concomitant use of
other CNS depressant drugs with opioid analgesics [see DRUG INTERACTIONS].
If the decision is made to prescribe a benzodiazepine or other CNS depressant concomitantly with an
opioid analgesic, prescribe the lowest effective dosages and minimum durations of concomitant use. In
patients already receiving an opioid analgesic, prescribe a lower initial dose of the benzodiazepine or
other CNS depressant than indicated in the absence of an opioid, and titrate based on clinical response.
If an opioid analgesic is initiated in a patient already taking a benzodiazepine or other CNS depressant,
prescribe a lower initial dose of the opioid analgesic, and titrate based on clinical response. Follow
patients closely for signs and symptoms of respiratory depression and sedation.
Advise both patients and caregivers about the risks of respiratory depression and sedation when ACTIQ
is used with benzodiazepines or other CNS depressants (including alcohol and illicit drugs). Advise
patients not to drive or operate heavy machinery until the effects of concomitant use of the
benzodiazepine or other CNS depressant have been determined. Screen patients for risk of substance
use disorders, including opioid abuse and misuse, and warn them of the risk for overdose and death
associated with the use of additional CNS depressants including alcohol and illicit drugs [see DRUG INTERACTIONS and PATIENT INFORMATION].
Risk Of Medication Errors
When prescribing, do not convert a patient to ACTIQ from any other fentanyl product on a mcg per mcg
basis as ACTIQ and other fentanyl products are not equivalent on a microgram per microgram basis.
ACTIQ is not a generic version of other transmucosal immediate release fentanyl (TIRF) formulations.
When dispensing, do not substitute an ACTIQ prescription for any other TIRF formulation under any
circumstances. Other TIRF formulations and ACTIQ are not equivalent. Substantial differences exist in
the pharmacokinetic profile of ACTIQ compared to other fentanyl products including other TIRF
formulations that result in clinically important differences in the rate and extent of absorption of
fentanyl. As a result of these differences, the substitution of ACTIQ for any other fentanyl product may
result in a fatal overdose.
There are no safe conversion directions available for patients on any other fentanyl products. (Note:
This includes oral, transdermal, or parenteral formulations of fentanyl.) Therefore, for opioid tolerant
patients, the initial dose of ACTIQ should always be 200 mcg. Each patient should be individually
titrated to provide adequate analgesia while minimizing side effects [see DOSAGE AND ADMINISTRATION
].
Addiction, Abuse, And Misuse
ACTIQ contains fentanyl, a Schedule II controlled substance. As an opioid, ACTIQ exposes users to
the risks of addiction, abuse, and misuse [see Drug Abuse And Dependence].
Although the risk of addiction in any individual is unknown, it can occur in patients appropriately
prescribed ACTIQ. Addiction can occur at recommended dosages and if the drug is misused or abused.
Assess each patient’s risk for opioid addiction, abuse, or misuse prior to prescribing ACTIQ, and
monitor all patients receiving ACTIQ for the development of these behaviors and conditions. Risks are
increased in patients with a personal or family history of substance abuse (including drug or alcohol
abuse or addiction) or mental illness (e.g., major depression). The potential for these risks should not,
however, prevent the proper management of pain in any given patient. Patients at increased risk may be
prescribed opioids such as ACTIQ, but use in such patients necessitates intensive counseling about the
risks and proper use of ACTIQ along with intensive monitoring for signs of addiction, abuse, and
misuse.
Opioids are sought by drug abusers and people with addiction disorders and are subject to criminal
diversion. Consider these risks when prescribing or dispensing ACTIQ. Strategies to reduce these
risks include prescribing the drug in the smallest appropriate quantity and advising the patient on the
proper disposal of unused drug [see PATIENT INFORMATION]. Contact local state
professional licensing board or state controlled substances authority for information on how to prevent
and detect abuse or diversion of this product.
Transmucosal Immediate Release Fentanyl (TIRF) Risk Evaluation And Mitigation Strategy
(REMS) Access Program
Because of the risk for misuse, abuse, addiction, and overdose [see Addiction, Abuse, And Misuse],
ACTIQ is available only through a restricted program called the TIRF REMS Access program. Under
the TIRF REMS Access program, outpatients, healthcare professionals who prescribe for outpatient
use, pharmacies, and distributors must enroll in the program. For inpatient administration (e.g., hospitals,
hospices, and long-term care facilities that prescribe for inpatient use) of ACTIQ, patient and
prescriber enrollment is not required.
Required components of the TIRF REMS Access program are:
- Healthcare professionals, who prescribe ACTIQ for outpatient use, must review the prescriber
educational materials for the TIRF REMS Access program, enroll in the program, and comply
with the REMS requirements.
- To receive ACTIQ, outpatients must understand the risks and benefits and sign a Patient-
Prescriber Agreement.
- Pharmacies that dispense ACTIQ must enroll in the program, and agree to comply with the REMS
requirements.
- Wholesalers and distributors that distribute ACTIQ must enroll in the program, and distribute only
to authorized pharmacies.
- Further information, including a list of qualified pharmacies/distributors, is available at
www.TIRFREMSAccess.com or by calling 1-866-822-1483.
Neonatal Opioid Withdrawal Syndrome
Prolonged use of ACTIQ during pregnancy can result in withdrawal in the neonate. Neonatal opioid
withdrawal syndrome, unlike opioid withdrawal syndrome in adults, may be life-threatening if not
recognized and treated, and requires management according to protocols developed by neonatology
experts. Observe newborns for signs of neonatal opioid withdrawal syndrome and manage accordingly.
Advise pregnant women using opioids for a prolonged period of the risk of neonatal opioid withdrawal
syndrome and ensure that appropriate treatment will be available [see Use In Specific Populations , PATIENT INFORMATION].
Life-Threatening Respiratory Depression In Patients With Chronic Pulmonary Disease Or In
Elderly, Cachectic, Or Debilitated Patients
The use of ACTIQ in patients with acute or severe bronchial asthma in an unmonitored setting or in the
absence of resuscitative equipment is contraindicated.
Patients With Chronic Pulmonary Disease
ACTIQ-treated patients with significant chronic obstructive
pulmonary disease or cor pulmonale, and those with a substantially decreased respiratory reserve,
hypoxia, hypercapnia, or pre-existing respiratory depression are at increased risk of decreased
respiratory drive including apnea, even at recommended dosages of ACTIQ [see Life-Threatening Respiratory Depression].
Elderly, Cachectic, Or Debilitated Patients
Life-threatening respiratory depression is more likely to
occur in elderly, cachectic, or debilitated patients because they may have altered pharmacokinetics or
altered clearance compared to younger, healthier patients [see Life-Threatening Respiratory Depression].
Monitor such patients closely, particularly when initiating and titrating ACTIQ and when ACTIQ is
given concomitantly with other drugs that depress respiration [see Life-Threatening Respiratory Depression].
Alternatively, consider the use of non-opioid analgesics in these patients.
Serotonin Syndrome With Concomitant Use Of Serotonergic Drugs
Cases of serotonin syndrome, a potentially life-threatening condition, have been reported during
concomitant use of ACTIQ with serotonergic drugs. Serotonergic drugs include selective serotonin
reuptake inhibitors (SSRIs), serotonin and norepinephrine reuptake inhibitors (SNRIs), tricyclic
antidepressants (TCAs), triptans, 5-HT3 receptor antagonists, drugs that affect the serotonergic
neurotransmitter system (e.g., mirtazapine, trazodone, tramadol), and drugs that impair metabolism of
serotonin (including MAO inhibitors, both those intended to treat psychiatric disorders and also others,
such as linezolid and intravenous methylene blue) [see DRUG INTERACTIONS]. This may occur within the
recommended dosage range.
Serotonin syndrome symptoms may include mental status changes (e.g., agitation, hallucinations, coma),
autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations
(e.g., hyperreflexia, incoordination, rigidity), and/or gastrointestinal symptoms (e.g., nausea, vomiting,
diarrhea). The onset of symptoms generally occurs within several hours to a few days of concomitant
use, but may occur later than that. Discontinue ACTIQ if serotonin syndrome is suspected.
Adrenal Insufficiency
Cases of adrenal insufficiency have been reported with opioid use, more often following greater than
one month of use. Presentation of adrenal insufficiency may include non-specific symptoms and signs
including nausea, vomiting, anorexia, fatigue, weakness, dizziness, and low blood pressure. If adrenal
insufficiency is suspected, confirm the diagnosis with diagnostic testing as soon as possible. If adrenal
insufficiency is diagnosed, treat with physiologic replacement doses of corticosteroids. Wean the
patient off of the opioid to allow adrenal function to recover and continue corticosteroid treatment until
adrenal function recovers. Other opioids may be tried as some cases reported use of a different opioid
without recurrence of adrenal insufficiency. The information available does not identify any particular
opioids as being more likely to be associated with adrenal insufficiency.
Severe Hypotension
ACTIQ may cause severe hypotension including orthostatic hypotension and syncope in ambulatory
patients. There is increased risk in patients whose ability to maintain blood pressure has already been
compromised by a reduced blood volume or concurrent administration of certain CNS depressant drugs
(e.g. phenothiazines or general anesthetics) [see DRUG INTERACTIONS]. Monitor these patients for signs
of hypotension after initiating or titrating the dosage of ACTIQ. In patients with circulatory shock,
ACTIQ may cause vasodilation that can further reduce cardiac output and blood pressure. Avoid the
use of ACTIQ in patients with circulatory shock.
Risks Of Use In Patients With Increased Intracranial Pressure, Brain Tumors , Head Injury,
Or Impaired Consciousness
In patients who may be susceptible to the intracranial effects of CO2 retention (e.g., those with evidence
of increased intracranial pressure or brain tumors), ACTIQ may reduce respiratory drive, and the
resultant CO2 retention can further increase intracranial pressure. Monitor such patients for signs of
sedation and respiratory depression, particularly when initiating therapy with ACTIQ.
Opioids may also obscure the clinical course in a patient with a head injury. Avoid the use of ACTIQ in
patients with impaired consciousness or coma.
Risks Of Use In Patients With Gastrointestinal Conditions
ACTIQ is contraindicated in patients with known or suspected gastrointestinal obstruction, including
paralytic ileus.
The fentanyl in ACTIQ may cause spasm of the sphincter of Oddi. Opioids may cause increases in
serum amylase. Monitor patients with biliary tract disease, including acute pancreatitis for worsening
symptoms.
Increased Risk Of Seizures In Patients With Seizure Disorders
The fentanyl in ACTIQ may increase the frequency of seizures in patients with seizure disorders, and
may increase the risk of seizures occurring in other clinical settings associated with seizures. Monitor
patients with a history of seizure disorders for worsened seizure control during ACTIQ therapy.
Risks Of Driving And Operating Machinery
ACTIQ may impair the mental or physical abilities needed to perform potentially hazardous activities
such as driving a car or operating machinery. Warn patients not to drive or operate dangerous machinery
unless they are tolerant to the effects of ACTIQ and know how they will react to the medication.
Cardiac Disease
Intravenous fentanyl may produce bradycardia. Therefore, use ACTIQ with caution in patients with
bradyarrhythmias.
MAO Inhibitors
ACTIQ is not recommended for use in patients who have received MAO inhibitors within 14 days,
because severe and unpredictable potentiation by MAO inhibitors has been reported with opioid
analgesics [see DRUG INTERACTIONS].
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Life-Threatening Respiratory Depression
Inform patients of the risk of life-threatening respiratory depression, including information that the risk
is greatest when starting ACTIQ or when the dosage is increased, and that it can occur even at
recommended dosages [see WARNINGS AND PRECAUTIONS]. Advise patients how to recognize
respiratory depression and to seek medical attention if breathing difficulties develop.
Accidental Ingestion
- Physicians and dispensing pharmacists must specifically question patients or caregivers about the
presence of children in the home (on a full time or visiting basis) and counsel them regarding the
dangers to children from inadvertent exposure [see WARNINGS AND PRECAUTIONS].
- Inform patients that accidental ingestion, especially in children, may result in respiratory
depression or death [see WARNINGS AND PRECAUTIONS].
- Instruct patients to take steps to store ACTIQ securely and to dispose of unused ACTIQ [see WARNINGS AND PRECAUTIONS , PATIENT INFORMATION, Disposal of Used ACTIQ
Units].
- Instruct patients and caregivers to keep both used and unused ACTIQ out of the reach of children
[see WARNINGS AND PRECAUTIONS].
- Inform patients and their caregivers that, in the event that a unit is not completely consumed, it must
be properly disposed as soon as possible [see WARNINGS AND PRECAUTIONS , PATIENT INFORMATION, Disposal of Used ACTIQ Units].
ACTIQ Child Safety Kit
Provide patients and their caregivers who have children in the home or visiting with an ACTIQ
Child Safety Kit, which contains educational materials and safe interim storage containers to help
patients store ACTIQ and other medicines out of the reach of children. To obtain a supply of
Child Safety Kits, health care professionals can call 1-888-534-3119.
Interactions With Benzodiazepines And Other CNS Depressants (Including Alcohol)
Inform patients and caregivers that potentially fatal additive effects may occur if ACTIQ is used with
benzodiazepines or other CNS depressants, including alcohol, and not to use these concomitantly unless
supervised by a healthcare provider [see WARNINGS AND PRECAUTIONS, DRUG INTERACTIONS].
Addiction, Abuse, And Misuse
Inform patients that the use of ACTIQ, even when taken as recommended, can result in addiction, abuse,
and misuse, which can lead to overdose and death [see WARNINGS AND PRECAUTIONS]. Instruct patients
not to share ACTIQ with others and to take steps to protect ACTIQ from theft or misuse.
Transmucosal Immediate-Release Fentanyl (TIRF) REMS
Advise patients of the following information pertaining to the TIRF REMS
- Inform outpatients that they must be enrolled in the TIRF REMS Access program before they
can receive ACTIQ.
- Allow patients the opportunity to ask questions and discuss any concerns regarding ACTIQ
or the TIRF REMS Access program.
- As required by the TIRF REMS Access program, review the contents of the ACTIQ
Medication Guide with every patient before initiating treatment with ACTIQ.
- Advise the patient that ACTIQ is available only from pharmacies that are enrolled in the
TIRF REMS Access program, and provide them with the telephone number and website for
information on how to obtain the drug.
- Advise the patient that only enrolled healthcare providers may prescribe ACTIQ.
- Inform the patient that they must sign the Patient-Prescriber Agreement to acknowledge that
they understand the risks of ACTIQ.
- Advise patients that they may be requested to participate in a survey to evaluate the
effectiveness of the TIRF REMS Access program [see WARNINGS AND PRECAUTIONS].
Serotonin Syndrome
Inform patients that opioids could cause a rare but potentially life-threatening condition resulting from
concomitant administration of serotonergic drugs. Warn patients of the symptoms of serotonin syndrome
and to seek medical attention right away if symptoms develop. Instruct patients to inform their physicians
if they are taking, or plan to take serotonergic medications [see WARNINGS AND PRECAUTIONS , DRUG INTERACTIONS].
MAOI Interaction
Inform patients to avoid taking ACTIQ while using any drugs that inhibit monoamine oxidase. Patients
should not start MAOIs while taking ACTIQ [see WARNINGS AND PRECAUTIONS ;DRUG INTERACTIONS].
Adrenal Insufficiency
Inform patients that opioids could cause adrenal insufficiency, a potentially life-threatening condition.
Adrenal insufficiency may present with non-specific symptoms and signs such as nausea, vomiting,
anorexia, fatigue, weakness, dizziness, and low blood pressure. Advise patients to seek medical
attention if they experience a constellation of these symptoms [see WARNINGS AND PRECAUTIONS].
Important Administration Instructions
[see DOSAGE AND ADMINISTRATION]
- Instruct patients not to take ACTIQ for acute pain, postoperative pain, pain from injuries, headache,
migraine or any other short-term pain, even if they have taken other opioid analgesics for these
conditions.
- Instruct patients on the meaning of opioid tolerance and that ACTIQ is only to be used as a
supplemental pain medication for patients with pain requiring around-the-clock opioids, who have
developed tolerance to the opioid medication, and who need additional opioid treatment of
breakthrough pain episodes.
- Instruct patients that, if they are not taking an opioid medication on a scheduled basis (around-theclock),
they should not take ACTIQ.
- Instruct patients that, if the breakthrough pain episode is not relieved 15 minutes after finishing the
ACTIQ unit, they may take only one additional unit of ACTIQ using the same strength for that
episode. Thus, patients should take no more than two units of ACTIQ for any breakthrough pain
episode.
- Instruct patients that they MUST wait at least 4 hours before treating another episode of
breakthrough pain with ACTIQ.
- Instruct patients NOT to share ACTIQ and that sharing ACTIQ with anyone else could result in
the other individual's death due to overdose.
- Make patients aware that ACTIQ contains fentanyl which is a strong pain medication similar to
hydromorphone, methadone, morphine, oxycodone, and oxymorphone.
- Caution patients to talk to their doctor if breakthrough pain is not alleviated or worsens after taking
ACTIQ.
- Instruct patients to use ACTIQ exactly as prescribed by their doctor and not to take ACTIQ more
often than prescribed.
Hypotension
Inform patients that ACTIQ may cause orthostatic hypotension and syncope. Instruct patients how to
recognize symptoms of low blood pressure and how to reduce the risk of serious consequences should
hypotension occur (e.g., sit or lie down, carefully rise from a sitting or lying position) [see WARNINGS AND PRECAUTIONS].
Anaphylaxis
Inform patients that anaphylaxis have been reported with ingredients contained in ACTIQ. Advise
patients how to recognize such a reaction and when to seek medical attention [see CONTRAINDICATIONS , ADVERSE REACTIONS]
Pregnancy
Neonatal Opioid Withdrawal Syndrome
Inform patients that prolonged use of ACTIQ during pregnancy can result in neonatal opioid
withdrawal syndrome, which may be life-threatening if not recognized and treated [see WARNINGS AND PRECAUTIONS , Use In Specific Populations].
Embryo-Fetal Toxicity
Inform female patients of reproductive potential that ACTIQ can cause fetal harm and to inform
their healthcare provider of a known or suspected pregnancy [see Use In Specific Populations].
Lactation
Advise nursing mothers to monitor infants for increased sleepiness (more than usual), breathing
difficulties, or limpness. Instruct nursing mothers to seek immediate medical care if they notice these
signs [see Use In Specific Populations].
Infertility
Inform patients that chronic use of opioids may cause reduced fertility. It is not known whether these
effects on fertility are reversible [see Use In Specific Populations].
Driving Or Operating Heavy Machinery
Inform patients that ACTIQ may impair the ability to perform potentially hazardous activities such as
driving a car or operating heavy machinery. Advise patients not to perform such tasks until they know
how they will react to the medication [see WARNINGS AND PRECAUTIONS].
Constipation
Advise patients of the potential for severe constipation, including management instructions and when to
seek medical attention [see ADVERSE REACTIONS, CLINICAL PHARMACOLOGY].
Dental Decay
Because each ACTIQ unit contains approximately 2 grams of sugar (hydrated dextrates), frequent
consumption may increase the risk of dental decay. The occurrence of dry mouth associated with the
use of opioid medications (such as fentanyl) may add to this risk.
Post-marketing reports of dental decay have been received in patients taking ACTIQ [see ADVERSE REACTIONS]. In some of these patients, dental decay occurred despite reported routine oral hygiene.
As dental decay in cancer patients may be multi-factorial, patients using ACTIQ should consult their
dentist to ensure appropriate oral hygiene.
Diabetic Patients
Advise diabetic patients that ACTIQ contains approximately 2 grams of sugar per unit.
Disposal Of Used ACTIQ Units
Instruct patients on proper disposal of completely used and partially used ACTIQ units as follows:
After consumption of the unit is complete and the matrix is totally dissolved, throw away the
handle in a trash container that is out of the reach of children.
If any of the drug matrix remains on the handle, place the handle under hot running tap water until
all of the drug matrix is dissolved, and then dispose of the handle in a place that is out of the reach
of children.
Dispose of handles in the child-resistant container (as described in steps 1 and 2) at least once a
day.
If the patient does not entirely consume the unit and the remaining drug cannot be immediately dissolved
under hot running water, the patient or caregiver must temporarily store the ACTIQ unit in the specially
provided child-resistant container out of the reach of children until proper disposal is possible.
Disposal Of Unopened ACTIQ Units When No Longer Needed
Patients and members of their household must be advised to dispose of any unopened units remaining
from a prescription as soon as they are no longer needed.
To dispose of the unused ACTIQ units:
- Remove the ACTIQ unit from its blister package using scissors, and hold the ACTIQ by its handle
over the toilet bowl.
- Using wire-cutting pliers cut off the drug matrix end so that it falls into the toilet.
- Dispose of the handle in a place that is out of the reach of children.
- Repeat steps 1, 2, and 3 for each ACTIQ unit. Flush the toilet twice after 5 units have been cut and
deposited into the toilet.
Do not flush the entire ACTIQ units, ACTIQ handles, blister packages, or cartons down the toilet.
Dispose of the handle where children cannot reach it.
Detailed instructions for the proper storage, administration, disposal, and important instructions for
managing an overdose of ACTIQ are provided in the ACTIQ Medication Guide. Encourage patients to
read this information in its entirety and give them an opportunity to have their questions answered.
In the event that a caregiver requires additional assistance in disposing of excess unusable units that
remain in the home after a patient has expired, instruct them to call the toll-free number for Teva
Pharmaceuticals (1-888-483-8279) or seek assistance from their local DEA office.
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
Carcinogenesis
Fentanyl was evaluated for carcinogenic potential in a 104-week rat study and in a 6-month Tg.AC
transgenic mouse study. In rats, doses up to 50 mcg/kg in males and 100 mcg/kg in females were
administered subcutaneously and no treatment-related neoplasms were observed (doses are equivalent to
1.13 and 2.7 times the exposure of a single human dose of 1600 mcg per pain episode, respectively,
based on an AUC comparison). In a 26-week transgenic mice model (Tg.AC), at topical doses up to 50
mcg/dose/day, no increase in the occurrence of treatment-related neoplasms was observed.
Mutagenesis
Fentanyl citrate was not mutagenic in the in vitro Ames reverse mutation assay in S. typhimurium or E.
coli, or the mouse lymphoma mutagenesis assay, and was not clastogenic in the in vivo mouse
micronucleus assay.
Impairment Of Fertility
In a fertility study, female rats were administered fentanyl subcutaneously for 14 days prior to mating
with untreated males at doses up to 300 mcg/kg and no effects on female fertility were observed. The
systemic exposure at the dose of 300 mcg/kg was approximately 4.0-times the exposure of a single
human dose of 1600 mcg per pain episode, based on an AUC comparison. Males were administered
fentanyl subcutaneously for 28 days prior to mating with untreated females at doses up to 300 mcg/kg.
At 300 mcg/kg, adverse effects on sperm parameters, which affected fertility, were observed. These
effects included decreased percent mobile sperm, decreased sperm concentrations as well as an
increase in the percent abnormal sperm. The dose in males at which no effects on fertility were
observed was 100 mcg/kg, which is approximately 2.7 times the exposure of a single human dose of
1600 mcg per pain episode, based on an AUC comparison.
Fentanyl has been shown to impair fertility in rats at doses of 30 mcg/kg IV and 160 mcg/kg
subcutaneously. Conversion to the human equivalent doses indicates that this is within the range of the
human recommended dosing for ACTIQ.
Use In Sepcific Populations
Pregnancy
Risk Summary
Prolonged use of opioid analgesics during pregnancy may cause neonatal opioid withdrawal syndrome
[see WARNINGS AND PRECAUTIONS]. Available data with ACTIQ in pregnant women are insufficient to
inform a drug-associated risk for major birth defects and miscarriage. In animal reproduction studies,
fentanyl administration to pregnant rats during organogenesis was embryocidal at doses within the range
of the human recommended dosing. When administered during gestation through lactation fentanyl
administration to pregnant rats resulted in reduced pup survival at doses within the range of the human
recommended dosing. No evidence of malformations were noted in animal studies completed to date
[see Data].
The estimated background risk of major birth defects and miscarriage for the indicated population is
unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In
the U.S. general population, the estimated background risk of major birth defects and miscarriage in
clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Clinical Considerations
Fetal/Neonatal Adverse Reactions
Prolonged use of opioid analgesics during pregnancy for medical or nonmedical purposes can result in
physical dependence in the neonate and neonatal opioid withdrawal syndrome shortly after birth.
Neonatal opioid withdrawal syndrome presents as irritability, hyperactivity and abnormal sleep pattern,
high pitched cry, tremor, vomiting, diarrhea and failure to gain weight. The onset of neonatal
withdrawal symptoms usually occurs in the first days after birth. The duration and severity of neonatal
opioid withdrawal syndrome may vary. Observe newborns for symptoms of neonatal opioid withdrawal
syndrome and manage accordingly [see WARNINGS AND PRECAUTIONS].
Labor or Delivery
Opioids cross the placenta and may produce respiratory depression and psycho-physiologic effects in
neonates. An opioid antagonist, such as naloxone, must be available for reversal of opioid-induced
respiratory depression in the neonate. ACTIQ is not recommended for use in pregnant women during or
immediately prior to labor, when other analgesic techniques are more appropriate. Opioid analgesics,
including ACTIQ, can prolong labor through actions which temporarily reduce the strength, duration,
and frequency of uterine contractions. However, this effect is not consistent and may be offset by an
increased rate of cervical dilation, which tends to shorten labor. Monitor neonates exposed to opioid
analgesics during labor for signs of excess sedation and respiratory depression.
Data
Human Data
In women treated acutely with intravenous or epidural fentanyl during labor, symptoms of neonatal
respiratory or neurological depression were no more frequent than would be expected in infants of
untreated mothers.
Transient neonatal muscular rigidity has been observed in infants whose mothers were treated with
intravenous fentanyl.
Animal Data
Fentanyl (25, 50, or 100 mcg/kg) citrate was administered subcutaneously to pregnant rats during the
period of organogenesis (Gestation Day, GD 6 to 17). Maternal toxicity and a decrease in fetal weights
were observed at 100 mcg/kg but no teratogenicity was seen in the study (the no observed effect level
of 50 mcg/kg is equivalent to 0.7 times the exposure of a single human dose of 1600 mcg per pain
episode, based on an AUC comparison). Fentanyl (50, 100, or 250 mcg/kg) was also administered
subcutaneously to pregnant rabbits during the period of organogenesis (GD 6-18). Maternal toxicity
was noted at doses >100 mcg/kg. No teratogenicity was seen in the study (250 mcg/kg dose is
equivalent to 3.5 times the exposure of a single human dose of 1600 mcg per pain episode, based on an
AUC comparison).
Fentanyl has been shown to embryocidal in pregnant rats at doses of 30 mcg/kg intravenously (0.2 times
the 1600 mcg dose of ACTIQ on a mg/m2 basis) from GD 6 to 18 and 160 mcg/kg subcutaneously (1
times the 1600 mcg dose of ACTIQ based on a mg/m2 basis). No evidence of teratogenicity was
reported.
No evidence of malformations or adverse effects on the fetus was reported in a published study in
which pregnant rats were administered fentanyl continuously via subcutaneously implanted osmotic
minipumps at doses of 10, 100, or 500 mcg/kg/day starting 2-weeks prior to breeding and throughout
pregnancy. The high dose was approximately 3 times the human dose of 1600 mcg ACTIQ per pain
episode on a mg/m2 basis and produced mean steady-state plasma levels that are 3.4 times higher than
the mean C observed following administration of 1600 mcg dose of ACTIQ in humans.
In a postnatal development study, pregnant rats were treated from GD 6 through Lactation Day (LD) 20
with subcutaneous doses of fentanyl (25, 50, 100, and 400 mcg/kg). Maternal toxicity was noted at doses
>100 mcg/kg. A reduction in pup growth and delayed attainment of developmental indices were
observed at >100 mcg/kg. No difference in the number of live pups/litter was seen at birth, however,
pup survival at LD 4 was reduced to 48% at 400 mcg/kg and by LD 21 pup survival was reduced to
30% and 26% at 100 and 400 mcg/kg, respectively. During lactation, fentanyl-related clinical signs
(decreased activity, skin cold to touch, and moribund appearance) were noted in the F1 pups, most
prominently in the 400 mcg/kg group. Pups from this group also had significantly reduced body weights
throughout the lactation period. The dose of fentanyl administered to rats at which no developmental
toxicity in the F1 generation was seen was 50 mcg/kg which is 0.6 times the exposure of a single human
dose of 1600 mcg per pain episode, based on an AUC comparison.
Lactation
Risk Summary
Fentanyl is present in breast milk. One published lactation study reports a relative infant dose of fentanyl
of 0.024%. However, there is insufficient information to determine the effects of fentanyl on the
breastfed infant and the effects of fentanyl on milk production. Because of the potential for serious
adverse reactions, including excess sedation and respiratory depression in a breastfed infant, advise
patients that breastfeeding is not recommended during treatment with ACTIQ.
Clinical Considerations
Monitor infants exposed to ACTIQ through breast milk for excess sedation and respiratory depression.
Withdrawal symptoms can occur in breastfed infants when maternal administration of an opioid analgesic
is stopped, or when breast-feeding is stopped.
Females And Males Of Reproductive Potential
Infertility
Chronic use of opioids may cause reduced fertility in females and males of reproductive potential. It is
not known whether these effects on fertility are reversible [see ADVERSE REACTIONS , CLINICAL PHARMACOLOGY , Nonclinical Toxicology].
Pediatric Use
Safety and effectiveness in pediatric patients below 16 years of age have not been established.
In a clinical study, 15 opioid-tolerant pediatric patients with breakthrough pain, ranging in age from 5 to
15 years, were treated with ACTIQ. The study was too small to allow conclusions on safety and
efficacy in this patient population. Twelve of the fifteen opioid-tolerant children and adolescents aged 5
to 15 years in this study received ACTIQ at doses ranging from 200 mcg to 600 mcg. The mean (CV%;
range) dose-normalized (to 200 mcg) C and AUC values were 0.87 ng/mL (51%; 0.42-1.30) and
4.54 ng h/mL (42%; 2.37-6.0), respectively, for children ages 5 to <11 years old (N = 3) and 0.68 ng/mL
(72%; 0.15-1.44) and 8.38 (192%; 0.84-50.78), respectively, for children ages ≥11 to <16 y (N = 9).
Geriatric Use
Of the 257 patients in clinical studies of ACTIQ in breakthrough cancer pain, 61 (24%) were 65 years
of age and older, while 15 (6%) were 75 years of age and older. Those patients over the age of 65
years were titrated to a mean dose that was about 200 mcg less than the mean dose titrated to by younger
patients. No difference was noted in the safety profile of the group over 65 years of age as compared
to younger patients in ACTIQ clinical trials.
Elderly patients have been shown to be more sensitive to the effects of fentanyl when administered
intravenously, compared with the younger population. Therefore, exercise caution when individually
titrating ACTIQ in elderly patients to provide adequate efficacy while minimizing risk.
Respiratory depression is the chief risk for elderly patients treated with opioids, and has occurred after
large initial doses were administered to patients who were not opioid-tolerant or when opioids were
co-administered with other agents that depress respiration. Titrate the dosage of ACTIQ slowly in
geriatric patients and monitor closely for signs of central nervous system and respiratory depression
[see WARNINGS AND PRECAUTIONS].
Fentanyl is known to be substantially excreted by the kidney, and the risk of adverse reactions to this
drug may be greater in patients with impaired renal function. Because elderly patients are more likely to
have decreased renal function, care should be taken in dose selection, and it may be useful to monitor
renal function.
Patients With Renal Or Hepatic Impairment
Insufficient information exists to make recommendations regarding the use of ACTIQ in patients with
impaired renal or hepatic function. Fentanyl is metabolized primarily via human cytochrome P450 3A4
isoenzyme system and mostly eliminated in urine. If the drug is used in these patients, it should be used
with caution because of the hepatic metabolism and renal excretion of fentanyl.
Sex
Both male and female opioid-tolerant cancer patients were studied for the treatment of breakthrough
cancer pain. No clinically relevant sex differences were noted either in dosage requirement or in
observed adverse reactions.
