5 WARNINGS AND PRECAUTIONS Suicidal Behavior and Ideation: Monitor for suicidal thoughts or behavior ( 5
1 Serious Psychiatric and Behavioral Reactions In the controlled partial-onset seizure clinical trials, hostility- and aggression-related adverse reactions occurred in 12% and 20% of patients randomized to receive perampanel at doses of 8 mg and 12 mg per day, respectively, compared to 6% of patients in the placebo group
Perampanel-treated patients experienced more hostility- and aggression-related adverse reactions that were serious, severe, and led to dose reduction, interruption, and discontinuation more frequently than placebo-treated patients
Some of these events were reported as serious and life-threatening

ZONISAMIDE

WARNINGS Potentially Fatal Reactions to Sulfonamides: Fatalities have occurred, although rarely, as a result of severe reactions to sulfonamides (zonisamide is a sulfonamide) including Stevens-Johnson syndrome, toxic epidermal necrolysis, fulminant hepatic necrosis, agranulocytosis, aplastic anemia, and other blood dyscrasias
If signs of hypersensitivity or other serious reactions occur, discontinue zonisamide immediately
Serious Skin Reactions Consideration should be given to discontinuing zonisamide in patients who develop an otherwise unexplained rash
