An Introduction to Afinitor Side EffectsJust like any medicine, Afinitor® (everolimus) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Afinitor. Your healthcare provider can discuss a more complete list with you.)
