An Introduction to Side Effects of Terbinafine

As with any medicine, side effects are possible with terbinafine hydrochloride (Lamisil®). However, not everyone who takes this drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, they are generally minor and either require no treatment or can easily be treated by you or your healthcare provider.
