An Introduction to EstroGel Side EffectsAs with any medicine, EstroGel® (estradiol gel) can cause side effects. However, not everyone who takes EstroGel will experience side effects. 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 easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with EstroGel. Your healthcare provider can discuss a more complete list of EstroGel side effects with you.)
