WARNINGS
Included as part of the PRECAUTIONS section.
PRECAUTIONS
Never Share A LEVEMIR® FlexTouch® Between Patients
LEVEMIR® FlexTouch® must never be shared between
patients, even if the needle is changed. Sharing poses a risk for transmission
of blood-borne pathogens.
Dosage Adjustment And Monitoring
Glucose monitoring is essential for all patients
receiving insulin therapy. Changes to an insulin regimen should be made
cautiously and only under medical supervision.
Changes in insulin strength, manufacturer, type, or
method of administration may result in the need for a change in the insulin
dose or an adjustment of concomitant anti-diabetic treatment.
As with all insulin preparations, the time course of
action for LEVEMIR® may vary in different individuals or at different times in
the same individual and is dependent on many conditions, including the local
blood supply, local temperature, and physical activity.
Administration
LEVEMIR® should only be administered subcutaneously.
Do not administer LEVEMIR® intravenously or
intramuscularly. The intended duration of activity of LEVEMIR® is dependent on
injection into subcutaneous tissue. Intravenous or intramuscular administration
of the usual subcutaneous dose could result in severe hypoglycemia [see Hypoglycemia].
Do not use LEVEMIR® in insulin infusion pumps.
Do not dilute or mix LEVEMIR® with any other insulin or
solution. If LEVEMIR® is diluted or mixed, the pharmacokinetic or
pharmacodynamic profile (e.g., onset of action, time to peak effect) of LEVEMIR®
and the mixed insulin may be altered in an unpredictable manner.
Hypoglycemia
Hypoglycemia is the most common adverse reaction of
insulin therapy, including LEVEMIR®. The risk of hypoglycemia increases with
intensive glycemic control.
When a GLP-1 receptor agonist is used in combination with
LEVEMIR®, the LEVEMIR® dose may need to be lowered or more conservatively
titrated to minimize the risk of hypoglycemia [see ADVERSE REACTIONS].
All patients must be educated to recognize and manage
hypoglycemia. Severe hypoglycemia can lead to unconsciousness or convulsions
and may result in temporary or permanent impairment of brain function or death.
Severe hypoglycemia requiring the assistance of another person or parenteral
glucose infusion, or glucagon administration has been observed in clinical
trials with insulin, including trials with LEVEMIR®.
The timing of hypoglycemia usually reflects the
time-action profile of the administered insulin formulations. Other factors
such as changes in food intake (e.g., amount of food or timing of meals),
exercise, and concomitant medications may also alter the risk of hypoglycemia [see
DRUG INTERACTIONS].
The prolonged effect of subcutaneous LEVEMIR® may delay
recovery from hypoglycemia.
As with all insulins, use caution in patients with
hypoglycemia unawareness and in patients who may be predisposed to hypoglycemia
(e.g., the pediatric population and patients who fast or have erratic food
intake). The patient's ability to concentrate and react may be impaired as a
result of hypoglycemia. This may present a risk in situations where these
abilities are especially important, such as driving or operating other
machinery.
Early warning symptoms of hypoglycemia may be different
or less pronounced under certain conditions, such as longstanding diabetes,
diabetic neuropathy, use of medications such as beta-blockers, or intensified
glycemic control [see DRUG INTERACTIONS]. These situations may result in
severe hypoglycemia (and, possibly, loss of consciousness) prior to the
patient's awareness of hypoglycemia.
Hypersensitivity And Allergic Reactions
Severe, life-threatening, generalized allergy, including
anaphylaxis, can occur with insulin products, including LEVEMIR®.
Renal Impairment
No difference was observed in the pharmacokinetics of
insulin detemir between non-diabetic individuals with renal impairment and
healthy volunteers. However, some studies with human insulin have shown
increased circulating insulin concentrations in patients with renal impairment.
Careful glucose monitoring and dose adjustments of insulin, including LEVEMIR®,
may be necessary in patients with renal impairment [see CLINICAL
PHARMACOLOGY].
Hepatic Impairment
Non-diabetic individuals with severe hepatic impairment
had lower systemic exposures to insulin detemir compared to healthy volunteers.
However, some studies with human insulin have shown increased circulating
insulin concentrations in patients with liver impairment. Careful glucose monitoring
and dose adjustments of insulin, including LEVEMIR®, may be necessary in
patients with hepatic impairment [see CLINICAL PHARMACOLOGY].
Drug Interactions
Some medications may alter insulin requirements and
subsequently increase the risk for hypoglycemia or hyperglycemia [see DRUG
INTERACTIONS].
Fluid Retention And Heart Failure With Concomitant Use Of
PPAR-gamma Agonists
Thiazolidinediones (TZDs), which are peroxisome
proliferator-activated receptor (PPAR)-gamma agonists, can cause dose-related fluid
retention, particularly when used in combination with insulin. Fluid retention
may lead to or exacerbate heart failure. Patients treated with insulin,
including LEVEMIR®, and a PPAR-gamma agonist should be observed for signs and
symptoms of heart failure. If heart failure develops, it should be managed
according to current standards of care, and discontinuation or dose reduction
of the PPAR-gamma agonist must be considered.
Patient Counseling Information
See FDA-Approved Patient Labeling (PATIENT INFORMATION and Instructions for Use)
Never Share A LEVEMIR® FlexTouch® Between Patients
Advise patients that they must never share a LEVEMIR® FlexTouch®
with another person, even if the needle is changed, because doing so carries a
risk for transmission of bloodborne pathogens.
Instructions For Patients
Patients should be informed that changes to insulin
regimens must be made cautiously and only under medical supervision. Patients
should be informed about the potential side effects of insulin therapy,
including hypoglycemia, weight gain, lipodystrophy (and the need to rotate
injection sites within the same body region), and allergic reactions. Patients
should be informed that the ability to concentrate and react may be impaired as
a result of hypoglycemia. This may present a risk in situations where these
abilities are especially important, such as driving or operating other
machinery. Patients who have frequent hypoglycemia or reduced or absent warning
signs of hypoglycemia should be advised to use caution when driving or
operating machinery.
Accidental mix-ups between LEVEMIR® and other insulins,
particularly short-acting insulins, have been reported. To avoid medication
errors between LEVEMIR® and other insulins, patients should be instructed to
always check the insulin label before each injection.
LEVEMIR® must only be used if the solution is clear and
colorless with no particles visible. Patients must be advised that LEVEMIR® must
NOT be diluted or mixed with any other insulin or solution.
Patients should be instructed on self-management
procedures including glucose monitoring, proper injection technique, and
management of hypoglycemia and hyperglycemia. Patients should be instructed on
handling of special situations such as intercurrent conditions (illness,
stress, or emotional disturbances), an inadequate or skipped insulin dose,
inadvertent administration of an increased insulin dose, inadequate food
intake, and skipped meals.
Patients should receive proper training on how to use
Levemir®. Instruct patients that when injecting Levemir®, they must press and
hold down the dose button until the dose counter shows 0 and then keep the
needle in the skin and count slowly to 6. When the dose counter returns to 0,
the prescribed dose is not completely delivered until 6 seconds later. If the
needle is removed earlier, they may see a stream of insulin coming from the
needle tip. If so, the full dose will not be delivered (a possible under-dose
may occur by as much as 20%), and they should increase the frequency of
checking their blood glucose levels and possible additional insulin
administration may be necessary.
- If 0 does not appear in the dose counter after
continuously pressing the dose button, the patient may have used a blocked
needle. In this case they would not have received any insulin – even though the
dose counter has moved from the original dose that was set.
- If the patient did have a blocked needle, instruct them
to change the needle as described in Section 5 of the Instructions for Use and
repeat all steps in the IFU starting with Section 1: Prepare your pen with a
new needle. Make sure the patient selects the full dose needed.
Patients with diabetes should be advised to inform their
healthcare professional if they are pregnant or are contemplating pregnancy.
Refer patients to the LEVEMIR® “PATIENT INFORMATION” for additional
information.
Nonclinical Toxicology
Carcinogenicity, Mutagenicity, Impairment Of Fertility
Standard 2-year carcinogenicity studies in animals have
not been performed. Insulin detemir tested negative for genotoxic potential in
the in vitro reverse mutation study in bacteria, human peripheral blood
lymphocyte chromosome aberration test, and the in vivo mouse micronucleus test.
In a fertility and embryonic development study, insulin
detemir was administered to female rats before mating, during mating, and
throughout pregnancy at doses up to 300 nmol/kg/day (3 times a human dose of
0.5 Units/kg/day, based on plasma AUC ratio). There were no effects on
fertility in the rat.
Use In Specific Populations
Pregnancy
Pregnancy Category B
Risk Summary
The background risk of birth defects, pregnancy loss, or
other adverse events that exists for all pregnancies is increased in
pregnancies complicated by hyperglycemia. Female patients should be advised to
tell their physician if they intend to become, or if they become pregnant while
taking LEVEMIR®. A randomized controlled clinical trial of pregnant women with
type I diabetes using LEVEMIR® during pregnancy did not show an increase in the
risk of fetal abnormalities. Reproductive toxicology studies in non-diabetic
rats and rabbits that included concurrent human insulin control groups
indicated that insulin detemir and human insulin had similar effects regarding
embryotoxicity and teratogenicity that were attributed to maternal
hypoglycemia.
Clinical Considerations
The increased risk of adverse events in pregnancies
complicated by hyperglycemia may be decreased with good glucose control before
conception and throughout pregnancy. Because insulin requirements vary
throughout pregnancy and in the post-partum period, careful monitoring of
glucose control is essential in pregnant women.
Human Data
In an, open-label, clinical study, women with type 1
diabetes who were (between weeks 8 and 12 of gestation) or intended to become
pregnant were randomized 1:1 to LEVEMIR® (once or twice daily) or NPH insulin
(once, twice or thrice daily). Insulin aspart was administered before each
meal. A total of 152 women in the LEVEMIR® arm and 158 women in the NPH arm
were or became pregnant during the study (Total pregnant women = 310).
Approximately one half of the study participants in each arm were randomized as
pregnant and were exposed to NPH or to other insulins prior to conception and
in the first 8 weeks of gestation. In the 310 pregnant women, the mean
glycosylated hemoglobin (HbA1c) was < 7% at 10, 12, and 24 weeks of
gestation in both arms. In the intent-to-treat population, the adjusted mean
HbA1c (standard error) at gestational week 36 was 6.27% (0.053) in LEVEMIR®-treated
patient (n=138) and 6.33% (0.052) in NPH-treated patients (n=145); the
difference was not clinically significant.
Adverse reactions in pregnant patients occurring at an
incidence of ≥ 5% are shown in Table 7. The two most common adverse
reactions were nasopharyngitis and headache. These are consistent with findings
from other type 1 diabetes trials (see Table 1, ADVERSE REACTIONS.), and are not
repeated in Table 7.
The incidence of adverse reactions of pre-eclampsia was
10.5% (16 cases) and 7.0% (11 cases) in the LEVEMIR® and NPH insulin groups
respectively. Out of the total number of cases of pre-eclampsia, eight (8)
cases in the LEVEMIR® group and 1 case in the NPH insulin group required
hospitalization. The rates of pre-eclampsia observed in the study are within
expected rates for pregnancy complicated by diabetes. Pre-eclampsia is a
syndrome defined by symptoms, hypertension and proteinuria; the definition of
pre-eclampsia was not standardized in the trial making it difficult to
establish a link between a given treatment and an increased risk of
pre-eclampsia. All events were considered unlikely related to trial treatment.
In all nine (9) cases requiring hospitalization the women had healthy infants.
Events of hypertension, proteinuria and edema were reported less frequently in
the LEVEMIR® group than in the NPH insulin group as a whole. There was no
difference between the treatment groups in mean blood pressure during pregnancy
and there was no indication of a general increase in blood pressure.
In the NPH insulin group there were 6 serious adverse
reactions in four mothers of the following placental disorders, 'Placenta
previa', 'Placenta previa hemorrhage', and 'Premature separation of placenta'
and 1 serious adverse reaction of 'Antepartum haemorrhage'. There were none
reported in the LEVEMIR® group.
The incidence of early fetal death (abortions) was
similar in LEVEMIR® and NPH treated patients; 6.6% and 5.1%, respectively. The
abortions were reported under the following terms: 'Abortion spontaneous',
'Abortion missed', 'Blighted ovum', 'Cervical incompetence' and 'Abortion
incomplete'.

*Because clinical trials are conducted under widely
varying designs, the adverse reaction rates reported in one clinical trial may
not be easily compared to those rates reported in another clinical trial, and
may not reflect the rates actually observed in clinical practice. |
The proportion of subjects experiencing severe
hypoglycemia was 16.4% and 20.9% in LEVEMIR® and NPH treated patients
respectively. The rate of severe hypoglycemia was 1.1 and 1.2 events per
patient-year in LEVEMIR® and NPH treated patients respectively. Proportion and
incidence rates for non-severe episodes of hypoglycemia were similar in both
treatment groups (Table 8).

In about a quarter of infants, LEVEMIR® was detected in
the infant cord blood at levels above the lower level of quantification ( < 25
pmol/L).
No differences in pregnancy outcomes or the health of the
fetus and newborn were seen with LEVEMIR® use.
Animal Data
In a fertility and embryonic development study, insulin
detemir was administered to female rats before mating, during mating, and
throughout pregnancy at doses up to 300 nmol/kg/day (3 times a human dose of
0.5 Units/kg/day, based on plasma area under the curve (AUC) ratio). Doses of
150 and 300 nmol/kg/day produced numbers of litters with visceral anomalies.
Doses up to 900 nmol/ kg/day (approximately 135 times a human dose of 0.5
Units/kg/day based on AUC ratio) were given to rabbits during organogenesis.
Drug and dose related increases in the incidence of fetuses with gallbladder
abnormalities such as small, bilobed, bifurcated, and missing gallbladders were
observed at a dose of 900 nmol/ kg/day. The rat and rabbit embryofetal development
studies that included concurrent human insulin control groups indicated that
insulin detemir and human insulin had similar effects regarding embryotoxicity
and teratogenicity suggesting that the effects seen were the result of
hypoglycemia resulting from insulin exposure in normal animals.
Nursing Mothers
It is unknown whether LEVEMIR® is excreted in human milk.
Because many drugs, including human insulin, are excreted in human milk, use
caution when administering LEVEMIR® to a nursing woman. Women with diabetes who
are lactating may require adjustments of their insulin doses.
Pediatric Use
The pharmacokinetics, safety and effectiveness of
subcutaneous injections of LEVEMIR® have been established in pediatric patients
(age 2 to 17 years) with type 1 diabetes [see CLINICAL PHARMACOLOGY and Clinical
Studies]. LEVEMIR® has not been studied in pediatric patients younger than
2 years of age with type 1 diabetes. LEVEMIR® has not been studied in pediatric
patients with type 2 diabetes.
The dose recommendation when converting to LEVEMIR® is
the same as that described for adults [see DOSAGE AND ADMINISTRATION and
Clinical Studies]. As in adults, the dosage of LEVEMIR® must be
individualized in pediatric patients based on metabolic needs and frequent
monitoring of blood glucose.
Geriatric Use
In controlled clinical trials comparing LEVEMIR® to NPH
insulin or insulin glargine, 64 of 1624 patients (3.9%) in the type 1 diabetes
trials and 309 of 1082 patients (28.6%) in the type 2 diabetes trials were
≥ 65 years of age. A total of 52 (7 type 1 and 45 type 2) patients (1.9%)
were ≥ 75 years of age. No overall differences in safety or effectiveness
were observed between these patients and younger patients, but small sample
sizes, particularly for patients ≥ 65 years of age in the type 1 diabetes
trials and for patients ≥ 75 years of age in all trials limits
conclusions. Greater sensitivity of some older individuals cannot be ruled out.
In elderly patients with diabetes, the initial dosing, dose increments, and
maintenance dosage should be conservative to avoid hypoglycemia. Hypoglycemia
may be difficult to recognize in the elderly.
