A member asked:
Which of these valtrex (valacyclovir) or acyclovir and famvir pill doesn't block my dilantin?
A doctor has provided 1 answer
See below.: Both Valtrex (valacyclovir) and Acyclovir will interact with dilantin, lowering its' effectiveness. Dilantin does not interact wih famvir. You could consider switching anti-epileptic agents if the former agents are less expensive and equally effective.
