Arpizol 15 Aripiprazole Phenytoin Sodium
ModeratePhenytoin induces CYP3A4 and may substantially lower aripiprazole levels, reducing its effect.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
What to do: Consider increasing the aripiprazole dose and monitor response; reduce the dose if phenytoin is withdrawn.
