An Introduction to Alphagan Side Effects

As with any medicine, Alphagan® (brimonidine tartrate) can cause side effects. However, not everyone who uses the medication will have problems. 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.
