Warnings for Concerta
Included as part of the PRECAUTIONS section.
Precautions for Concerta
Abuse, Misuse, And Addiction
CONCERTA has a high potential for abuse and misuse. The use of CONCERTA exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. CONCERTA can be diverted for non-medical use into illicit channels or distribution [see Drug Abuse And Dependence]. Misuse and abuse of CNS stimulants, including CONCERTA, can result in overdose and death [see OVERDOSAGE], and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection.
Before prescribing CONCERTA, assess each patient’s risk for abuse, misuse, and addiction. Educate patients and their families about these risks and proper disposal of any unused drug. Advise patients to store CONCERTA in a safe place, preferably locked, and instruct patients to not give CONCERTA to anyone else. Throughout CONCERTA treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction.
Risks To Patients With Serious Cardiac Disease
Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who were treated with CNS stimulants at the recommended ADHD dosage.
Avoid CONCERTA use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease.
Increased Blood Pressure And Heart Rate
CNS stimulants may cause an increase in blood pressure (mean increase approximately 2 to 4 mmHg) and heart rate (mean increase approximately 3 to 6 bpm). Some patients may have larger increases.
Monitor all CONCERTA-treated patients for hypertension and tachycardia.
Psychiatric Adverse Reactions
Exacerbation Of Pre-existing Psychosis
CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a pre-existing psychotic disorder.
Induction Of A Manic Episode In Patients With Bipolar Disorder
CNS stimulants may induce a manic or mixed episode in patients. Prior to initiating CONCERTA treatment, screen patients for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or a family history of suicide, bipolar disorder, or depression).
New Psychotic Or Manic Symptoms
CNS stimulants, at the recommended dosage, may cause psychotic or manic symptoms (e.g., hallucinations, delusional thinking, or mania) in patients without a prior history of psychotic illness or mania. In a pooled analysis of multiple short-term, placebo-controlled studies of CNS stimulants, psychotic or manic symptoms occurred in approximately 0.1% of CNS stimulant-treated patients, compared with 0% of placebo-treated patients. If such symptoms occur, consider discontinuing CONCERTA.
Seizures
There is some clinical evidence that stimulants may lower the convulsive threshold in patients with prior history of seizures, in patients with prior EEG abnormalities in absence of seizures, and, very rarely, in patients without a history of seizures and no prior EEG evidence of seizures. In the presence of seizures, the drug should be discontinued.
Priapism
Prolonged and painful erections, sometimes requiring surgical intervention, have been reported with methylphenidate use in both adult and pediatric male patients [see ADVERSE REACTIONS]. Although priapism was not reported with methylphenidate initiation, it developed after some time on methylphenidate, often subsequent to an increase in dosage. Priapism also occurred during methylphenidate withdrawal (drug holidays or during discontinuation).
CONCERTA-treated patients who develop abnormally sustained or frequent and painful erections should seek immediate medical attention.
Peripheral Vasculopathy, Including Raynaud’s Phenomenon
CNS stimulants, including CONCERTA, used to treat ADHD are associated with peripheral vasculopathy, including Raynaud’s phenomenon. Signs and symptoms are usually intermittent and mild; however, sequelae have included digital ulceration and/or soft tissue breakdown. Effects of peripheral vasculopathy, including Raynaud’s phenomenon, were observed in post-marketing reports and at the therapeutic dosages of CNS stimulants in all age groups throughout the course of treatment. Signs and symptoms generally improved after dosage reduction or discontinuation of the CNS stimulant.
Careful observation for digital changes is necessary during CONCERTA treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for CONCERTA-treated patients who develop signs or symptoms of peripheral vasculopathy.
Long-Term Suppression Of Growth In Pediatric Patients
CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients.
Careful follow-up of weight and height in children ages 7 to 10 years who were randomized to either methylphenidate or nonmedication treatment groups over 14 months, as well as in naturalistic subgroups of newly methylphenidate-treated and nonmedication-treated children over 36 months (to the ages of 10 to 13 years), suggests that pediatric patients who received methylphenidate for 7 days per week throughout the year had a temporary slowing in growth rate (on average, a total of about 2 cm less growth in height and 2.7 kg less growth in weight over 3 years), without evidence of growth rebound during this development period. Closely monitor growth (weight and height) in CONCERTA-treated pediatric patients. Pediatric patients who are not growing or gaining height or weight as expected may need to have their treatment interrupted.
Potential For Gastrointestinal Obstruction
Because the CONCERTA tablet is nondeformable and does not appreciably change in shape in the GI tract, CONCERTA should not ordinarily be administered to patients with preexisting severe gastrointestinal narrowing (pathologic or iatrogenic, for example: esophageal motility disorders, small bowel inflammatory disease, “short gut” syndrome due to adhesions or decreased transit time, past history of peritonitis, cystic fibrosis, chronic intestinal pseudo-obstruction, or Meckel’s diverticulum). There have been rare reports of obstructive symptoms in patients with known strictures in association with the ingestion of drugs in nondeformable controlled-release formulations. Due to the controlled-release design of the tablet, CONCERTA should be used only in patients who are able to swallow the tablet whole [see Patient Counseling Information].
Hematologic Monitoring
Periodic CBC, differential, and platelet counts are advised during prolonged therapy.
Acute Angle Closure Glaucoma
There have been rare reports of angle closure glaucoma associated with methylphenidate treatment.
Although the mechanism is not clear, CONCERTA-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist.
Increased Intraocular Pressure And Glaucoma
There have been reports of an elevation of intraocular pressure (IOP) associated with methylphenidate treatment [see ADVERSE REACTIONS].
Prescribe CONCERTA to patients with open-angle glaucoma or abnormally increased IOP only if the benefit of treatment is considered to outweigh the risk. Closely monitor CONCERTA-treated patients with a history of abnormally increased IOP or open angle glaucoma.
Motor And Verbal Tics, And Worsening Of Tourette’s Syndrome
CNS stimulants, including methylphenidate, have been associated with the onset or exacerbation of motor and verbal tics [see ADVERSE REACTIONS]. Worsening of Tourette’s syndrome has also been reported.
Before initiating CONCERTA, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor CONCERTA-treated patients for the emergence or worsening of tics or Tourette’s syndrome, and discontinue treatment if clinically appropriate.
Patient Counseling Information
Advise the patient to read the FDA-approved patient labeling (Medication Guide).
Abuse, Misuse, And Addiction
Educate patients and their families about the risks of abuse, misuse, and addiction of CONCERTA, which can lead to overdose and death, and proper disposal of any unused drug [see WARNINGS AND PRECAUTIONS, Drug Abuse And Dependence, OVERDOSAGE]. Advise patients to store CONCERTA in a safe place, preferably locked, and instruct patients to not give CONCERTA to anyone else.
Risks To Patients With Serious Cardiac Disease
Advise patients that there are potential risks to patients with serious cardiac disease, including sudden death, with CONCERTA use. Instruct patients to contact a healthcare provider immediately if they develop symptoms such as exertional chest pain, unexplained syncope, or other symptoms suggestive of cardiac disease [see WARNINGS AND PRECAUTIONS].
Increased Blood Pressure And Heart Rate
Advise patients that CONCERTA can cause elevations in blood pressure and heart rate [see WARNINGS AND PRECAUTIONS].
Psychiatric Risks
Advise patients that CONCERTA, at recommended doses, can cause psychotic or manic symptoms, even in patients without a prior history of psychotic symptoms or mania [see WARNINGS AND PRECAUTIONS].
Priapism
Advise patients, caregivers, and family members of the possibility of painful or prolonged penile erections (priapism). Instruct the patient to seek immediate medical attention in the event of priapism [see WARNINGS AND PRECAUTIONS].
Circulation Problems In Fingers And Toes [Peripheral Vasculopathy, including Raynaud’s Phenomenon]
Instruct patients beginning treatment with CONCERTA about the risk of peripheral vasculopathy, including Raynaud’s phenomenon, and associated signs and symptoms: fingers or toes may feel numb, cool, painful, and/or may change color from pale, to blue, to red.
Instruct patients to report to their physician any new numbness, pain, skin color change, or sensitivity to temperature in fingers or toes.
Instruct patients to call their physician immediately with any signs of unexplained wounds appearing on fingers or toes while taking CONCERTA.
Further clinical evaluation (e.g., rheumatology referral) may be appropriate for certain patients.
Suppression Of Growth
Advise patients, caregivers, and family members that CONCERTA may cause slowing of growth and weight loss [see WARNINGS AND PRECAUTIONS].
Increased Intraocular Pressure (IOP) And Glaucoma
Advise patients that IOP and glaucoma may occur during treatment with CONCERTA [see WARNINGS AND PRECAUTIONS].
Motor And Verbal Tics, And Worsening Of Tourette’s Syndrome
Advise patients that motor and verbal tics and worsening of Tourette’s Syndrome may occur during treatment with CONCERTA. Instruct patients to notify their healthcare provider if emergence of new tics or worsening of tics or Tourette’s syndrome occurs [see WARNINGS AND PRECAUTIONS].
Administration Instructions
Patients should be informed that CONCERTA should be swallowed whole with the aid of liquids. Tablets should not be chewed, divided, or crushed. The medication is contained within a nonabsorbable shell designed to release the drug at a controlled rate. The tablet shell, along with insoluble core components, is eliminated from the body; patients should not be concerned if they occasionally notice in their stool something that looks like a tablet.

Nonclinical Toxicology
Carcinogenesis, Mutagenesis, And Impairment Of Fertility
Carcinogenesis
In a lifetime carcinogenicity study carried out in B6C3F1 mice, methylphenidate caused an increase in hepatocellular adenomas and, in males only, an increase in hepatoblastomas at a daily dose of approximately 60 mg/kg/day. This dose is approximately 30 times and 4 times the maximum recommended human dose of CONCERTA on a mg/kg and mg/m² basis, respectively. Hepatoblastoma is a relatively rare rodent malignant tumor type. There was no increase in total malignant hepatic tumors. The mouse strain used is sensitive to the development of hepatic tumors, and the significance of these results to humans is unknown.
Methylphenidate did not cause any increases in tumors in a lifetime carcinogenicity study carried out in F344 rats; the highest dose used was approximately 45 mg/kg/day, which is approximately 22 times and 5 times the maximum recommended human dose of CONCERTA on a mg/kg and mg/m² basis, respectively.
In a 24-week carcinogenicity study in the transgenic mouse strain p53+/-, which is sensitive to genotoxic carcinogens, there was no evidence of carcinogenicity. Male and female mice were fed diets containing the same concentration of methylphenidate as in the lifetime carcinogenicity study; the high-dose groups were exposed to 60 to 74 mg/kg/day of methylphenidate.
Mutagenesis
Methylphenidate was not mutagenic in the in vitro Ames reverse mutation assay or the in vitro mouse lymphoma cell forward mutation assay. Sister chromatid exchanges and chromosome aberrations were increased, indicative of a weak clastogenic response, in an in vitro assay in cultured Chinese Hamster Ovary cells. Methylphenidate was negative in vivo in males and females in the mouse bone marrow micronucleus assay.
Impairment Of Fertility
Methylphenidate did not impair fertility in male or female mice that were fed diets containing the drug in an 18-week Continuous Breeding study. The study was conducted at doses up to 160 mg/kg/day, approximately 80-fold and 8-fold the highest recommended human dose of CONCERTA on a mg/kg and mg/m² basis, respectively.
Use In Specific Populations
Pregnancy
Pregnancy Category C
Methylphenidate has been shown to have teratogenic effects in rabbits when given in doses of 200 mg/kg/day, which is approximately 100 times and 40 times the maximum recommended human dose on a mg/kg and mg/m² basis, respectively.
A reproduction study in rats revealed no evidence of harm to the fetus at oral doses up to 30 mg/kg/day, approximately 15-fold and 3-fold the maximum recommended human dose of CONCERTA on a mg/kg and mg/m² basis, respectively. The approximate plasma exposure to methylphenidate plus its main metabolite PPAA in pregnant rats was 1-2 times that seen in trials in volunteers and patients with the maximum recommended dose of CONCERTA based on the AUC.
The safety of methylphenidate for use during human pregnancy has not been established. There are no adequate and well-controlled studies in pregnant women. CONCERTA should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Labor And Delivery
The effect of CONCERTA on labor and delivery in humans is unknown.
Nursing Mothers
It is not known whether methylphenidate is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised if CONCERTA is administered to a nursing woman.
In lactating female rats treated with a single oral dose of 5 mg/kg radiolabeled methylphenidate, radioactivity (representing methylphenidate and/or its metabolites) was observed in milk and levels were generally similar to those in plasma.
Pediatric Use
CONCERTA should not be used in children under six years, since safety and efficacy in this age group have not been established. Long-term effects of methylphenidate in children have not been well established.
Geriatric Use
CONCERTA has not been studied in patients greater than 65 years of age.
