Cautions
Somnolence and asthenia occurred most frequently within first 4 weeks of treatment; patients should be monitored for signs and symptoms and advised not to drive or operate machinery until they have gained sufficient experience on levetiracetam to gauge whether it adversely affects ability to drive or operate machinery
As with most antiepileptic drugs, drug should generally be withdrawn gradually because of risk of increased seizure frequency and status epilepticus; if withdrawal needed because of serious adverse reaction, rapid discontinuation can be considered
Psychiatric reactions: 13.3% of adults and 37.6% of children treated with levetiracetam reported nonpsychotic behavioral symptoms (eg, aggression, agitation, anger, anxiety, apathy, depersonalization, lability, hostility, hyperkinesis, irritability, nervousness, neurosis, and personality disorder) compared to 6.2% and 18.6% of adult and pediatric placebo patients respectively; dose reduction or discontinuation may be required
Monitor patients for behavioral abnormalities including psychotic symptoms, suicidal ideation, irritability, aggressive behavior, and for new or worsening depression, suicidal thoughts/behavior, and/or unusual changes in mood or behavior
Serious dermatological reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) reported; median time of onset is reported to be 14-17 days; if signs or symptoms suggest SJS/TEN, use of this drug should not be resumed and alternative therapy should be considered
May impair ability to operate heavy machinery
Therapy can cause hematologic abnormalities, including decreases in white blood cell (WBC), neutrophil, and red blood cell (RBC) counts; decreases in hemoglobin and hematocrit; and increases in eosinophil counts; cases of agranulocytosis, pancytopenia, and thrombocytopenia reported in postmarketing setting; a complete blood count is recommended in patients experiencing significant weakness, pyrexia, recurrent infections, or coagulation disorders
Increases in eosinophil counts observed
Monitor patients 1 month to <4 years of age for increases in diastolic blood pressure
Seizure control during pregnancy: Physiological changes during pregnancy may gradually decrease therapeutic plasma concentrations, this is particularly pronounced during the 3rd trimester; closely monitor serum levels during pregnancy and through the postpartum period
Agranulocytosis reported; in pediatric patients (4 to <16 years of age), statistically significant decreases in WBC and neutrophil counts were seen in patients treated with immediate-release levetiracetam; no patient was discontinued secondary to low WBC or neutrophil counts
One percent of adult patients and 2% of pediatric patients (4 to 16 years of age) treated with immediate-release levetiracetam experienced psychotic symptoms (paranoia)
Use caution in renal impairment; adjust dose; use immediate release formulation, instead of the extended release formulation, in patients with ESRD requiring hemodialysis
Can cause anaphylaxis or angioedema after the first dose or at any time during treatment; if patient develops signs or symptoms of anaphylaxis or angioedema, therapy should be discontinued and patient should seek immediate medical attention; therapy should be discontinued permanently if clear alternative etiology for reaction cannot be established
Drug reaction with eosinophilia and systemic symptoms (DRESS)
- DRESS, also known as multiorgan hypersensitivity, has been reported in patients taking antiepileptic drugs, including levetiracetam; these events can be fatal or life-threatening, particularly if diagnosis and treatment do not occur as early as possible
- DRESS typically, although not exclusively, presents with fever, rash, lymphadenopathy, and/or facial swelling, in association with other organ system involvement, such as hepatitis, nephritis, hematological abnormalities, myocarditis, or myositis, sometimes resembling an acute viral infection
- Eosinophilia is often present; because this disorder is variable in its expression, other organ systems not noted here may be involved; it is important to note that early manifestations of hypersensitivity, such as fever or lymphadenopathy, may be present even though rash is not evident
- If such signs or symptoms are present, the patient should be evaluated immediately; this drug should be discontinued if an alternative etiology for signs or symptoms cannot be established
- Advise patients to avoid discontinuing medications without speaking to a healthcare provider
- Sudden discontinuation can lead to uncontrolled seizures
- Instruct patients to immediately go to emergency room if any unusual symptoms or reactions develop, including a rash, at any time while taking levetiracetam or clobazam
- Prompt recognition and early treatment is important for improving DRESS outcomes and decreasing mortality
- Symptoms of DRESS generally start 2-8 weeks after initiating
- DRESS can also be confused with other serious skin reactions (eg, SJS, TEN)
Pregnancy & Lactation
Pregnancy
There are no adequate and well-controlled studies in pregnant women; prolonged experience in pregnant women has not identified a drug-associated risk of major birth defects or miscarriage, based on published literature, which includes data from pregnancy registries, and reflects experience over two decades
In animal studies, levetiracetam produced evidence of developmental toxicity, including teratogenic effects, at doses similar to or greater than human therapeutic doses
Use during pregnancy only if the potential benefit justifies the potential risk to the fetus
Drug blood levels may decrease during pregnancy; physiological changes during pregnancy may affect drug concentration; decrease in drug plasma concentrations has been observed during pregnancy; this decrease is more pronounced during third trimester; dose adjustments may be necessary to maintain clinical response
Enroll patients in the North American Antiepileptic Drug pregnancy registry; 1-888-233-2334 or visit http://www.aedpregnancyregistry.org
Lactation
Drug is excreted in human milk; there are no data on effects of drug on breastfed infant, or on milk production
Unknown if distributed in human breast milk
Consider the developmental and health benefits of breastfeeding along with the mother’s clinical need for the drug, and any potential adverse effects on the breastfed infant from the drug or from the underlying maternal conditio
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
