Phenytoin
Older anticonvulsant — narrow therapeutic index
Phenytoin (Dilantin) is an older anticonvulsant with a narrow safe range. Levels are checked periodically. Many drug interactions and gum overgrowth are known long-term side effects.
How the pharmacy helps
We dispense 100 mg ER capsules and 50 mg chewables. Brand consistency matters — try not to switch generics without prescriber input.
