Although most people do not experience problems while taking Faslodex, side effects can occur during treatment. A few of the most commonly reported ones include nausea, weakness, and hot flashes. Some serious side problems reported with Faslodex include depression, signs of an allergic reaction, and signs of a blood clot. If you experience these or other serious side effects, let your doctor know right away.
An Introduction to Faslodex Side EffectsAs with any medicine, side effects are possible with Faslodex® (fulvestrant). However, not everyone who takes the medication 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 Faslodex. Your healthcare provider can discuss a more complete list with you.)
