Side Effects of Lamisil: An Introduction
As with any medicine, there are possible side effects with
Lamisil® (
terbinafine hydrochloride). However, not everyone who takes Lamisil will experience side effects. In fact, most people tolerate Lamisil quite well. If side effects do occur, in most cases they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Lamisil. Your healthcare provider can discuss a more complete list of Lamisil side effects with you.)
