Fycompa Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Fycompa (perampanel) is used to treat partial onset seizures in patients with epilepsy ages 12 years and older. Fycompa is in a new class of drugs to treat drug-resistant partial-onset seizures. Side effects include dizziness, sleepiness, fatigue, irritability, nausea, weight gain, and problems maintaining balance. Serious psychiatric and behavioral reactions including aggression, hostility, irritability, anger, and homicidal ideation and threats have been reported. Patients should be monitored for such reactions, as well as changes in mood, behaviors,

Starting dose of Fycompa is 2 mg taken once daily at bedtime. Patients taking anti-eleptic drugs (AEDs) should start on 4 mg of Fycompa. Dosage may be increased based on how well patients tolerate Fycompa. The maximum recommended dose is 12 mg taken once daily. Fycompa is not recommended for patients with decreased liver or kidney function, or patients on dialysis. Fycompa may decrease the effectiveness of hormonal contraceptives. Tegretol (carbamazepine), Carbatrol (carbamazepine), Equetro (carbamazepine), Trileptal (oxcarbazepine), Oxtellar XR (oxcarbazepine), Phenobarbital, and Mysoline (primidone), enzyme-inducing AEDs (phenobarbital and primidone), Rifadin (rifampin), Rifamate (rifampin and isoniazid), Rifater (rifampin, isoniazid and pyrazinamide), and St. John's Wort may interact with Fycompa. Fycompa is not recommended for use during pregnancy. It may cause fetal harm. It is not known if Fycompa passes into breast milk. Nursing mothers and their doctors should decide if the patient will take Fycompa or breastfeed. Patients should not do both. If a patient withdraws from Fycompa, there may be an increase in the frequency of seizures.

Fycompa FDA Prescribing Information: Side Effects
(Adverse Reactions)

SIDE EFFECTS

The following adverse reactions are discussed in more detail in other sections of the prescribing information:

Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

A total of 1,038 patients on perampanel (2, 4, 8, or 12 mg once daily) constituted the safety population in the pooled analysis of Phase 3 placebo controlled studies (Studies 1, 2, and 3) in patients with partial onset seizures. Approximately 51% of patients were female and the mean age was 35 years.

Adverse Reactions Leading to Discontinuation

In controlled Phase 3 clinical trials (Studies 1, 2, and 3), the rate of discontinuation as a result of an adverse reaction was 3%, 8% and 19% in patients randomized to receive FYCOMPA at the recommended doses of 4 mg, 8 mg and 12 mg/day, respectively, and 5% in patients randomized to receive placebo [see Clinical Studies]. The adverse events most commonly leading to discontinuation ( ≥ 1% in the 8 mg or 12 mg FYCOMPA group and greater than placebo) were dizziness, somnolence, vertigo, aggression, anger, ataxia, blurred vision, irritability, and dysarthria [see WARNINGS AND PRECAUTIONS].

Most Common Adverse Reactions

Table 2 gives the incidence in the Phase 3 controlled trials (Studies 1, 2, and 3) of the adverse reactions that occurred in ≥ 2% of patients with partial-onset seizures in any FYCOMPA dose group. Overall, the most frequently reported dose-related adverse reactions in patients receiving FYCOMPA at doses of 8 mg or 12 mg ( ≥ 4% and occurring at least 1% higher than the placebo group) included dizziness (36%), somnolence (16%), fatigue (10%), irritability (9%), falls (7%), nausea (7%), ataxia (5%), balance disorder (4%), gait disturbance (4%), vertigo (4%), and weight gain (4%). For almost every adverse reaction, rates were higher on 12 mg and more often led to dose reduction or discontinuation.

Weight Gain

Weight gain has been observed with FYCOMPA use in adults.

In the controlled Phase 3 epilepsy clinical trials, FYCOMPA-treated adults gained an average of 1.1 kg (2.5 lbs) compared to an average of 0.3 kg (0.7 lbs) in placebo-treated adults with a median exposure of 19 weeks. The percentages of adults who gained at least 7% and 15% of their baseline body weight in FYCOMPA-treated patients were 9.1% and 0.9%, respectively, as compared to 4.5% and 0.2% of placebo-treated patients, respectively.

Clinical monitoring of weight is recommended.

Comparison of Sex and Race

No significant sex differences were noted in the incidence of adverse reactions.

Although there were few non-Caucasian patients, no differences in the incidences of adverse reactions compared to Caucasian patients were observed.
