Side Effects of Tacrine: An Overview

As with any medicine, side effects are possible with tacrine hydrochloride (Cognex^®); however, not everyone who takes the medication will experience side effects. In fact, many people tolerate it quite well. If side effects do occur, they are often 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 tacrine. Your healthcare provider can discuss a more complete list of side effects with you.)
