Side Effects
6 ADVERSE REACTIONS The following serious adverse reactions are described below and elsewhere in the labeling: Serious Psychiatric and Behavioral Reactions [see Warnings and Precautions (5.1) ] Suicidal Behavior and Ideation [see Warnings and Precautions (5.2) ] Neurologic Effects [see Warnings and Precautions (5.3) ] Falls [see Warnings and Precautions (5.4) ] Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity [see Warnings and Precautions (5.5) ] Most common adverse reactions (≥5% and ≥1% higher than placebo) include dizziness, somnolence, fatigue, irritability, falls, nausea, weight gain, vertigo, ataxia, headache, vomiting, contusion, abdominal pain, and anxiety ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Sun Pharmaceutical Industries,...
Interactions
7 DRUG INTERACTIONS Contraceptives: 12 mg once daily may decrease the effectiveness of hormonal contraceptives containing levonorgestrel ( 7.1 ) Moderate and Strong CYP3A4 Inducers (including carbamazepine, oxcarbazepine, and phenytoin): increase clearance of perampanel and decrease perampanel plasma concentrations. When moderate or strong CYP3A4 inducers are introduced or withdrawn, monitor patients closely. Dose adjustment of perampanel tablets may be necessary ( 2.3 , 7.2 ) 7.1 Contraceptives With concomitant use, perampanel at a dose of 12 mg per day reduced levonorgestrel exposure by approximately 40% [see Clinical Pharmacology (12.3) ] . Use of perampanel with contraceptives containing levonorgestrel may render them less effective.
