LAMOTRIGINE ER

1 Serious Skin Rashes [see Boxed Warning] The risk of serious rash caused by treatment with Lamotrigine Extended-Release Tablets is not expected to differ from that with immediate-release lamotrigine [see Boxed Warning]
However, the relatively limited treatment experience with Lamotrigine Extended-Release Tablets makes it difficult to characterize the frequency and risk of serious rashes caused by treatment with Lamotrigine Extended-Release Tablets
Pediatric Population The incidence of serious rash associated with hospitalization and discontinuation of immediate-release lamotrigine in a prospectively followed cohort of pediatric patients (aged 2 to 16 years) with epilepsy receiving adjunctive therapy with immediate-release lamotrigine was approximately 0
There was 1 rash-related death in this 1,983-patient cohort

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
