FDA Warnings

PHENYTOIN SODIUM

5 WARNINGS AND PRECAUTIONS Withdrawal Precipitated Seizure : May precipitate status epilepticus
2 ) Serious Dermatologic Reactions : Discontinue phenytoin at the first sign of a rash, unless the rash is clearly not drug-related
1 Cardiovascular Risk Associated with Rapid Infusion Rapid intravenous administration of Phenytoin Sodium Injection increases the risk of adverse cardiovascular reactions, including severe hypotension and cardiac arrhythmias
Cardiac arrhythmias have included bradycardia, heart block, ventricular tachycardia, and ventricular fibrillation which have resulted in asystole, cardiac arrest, and death

VIGABATRIN

5 WARNINGS AND PRECAUTIONS Abnormal MRI signal changes and intramyelinic edema have been reported in some infants with Infantile Spasms receiving vigabatrin ( 5
4 ) Suicidal behavior and ideation: Antiepileptic drugs, including VIGADRONE, increase the risk of suicidal thoughts and behavior ( 5
Because of this risk and because, when it is effective, VIGADRONE provides an observable symptomatic benefit; patient response and continued need for treatment should be periodically assessed
For this reason, the understanding of the risk is primarily based on the adult experience
