Commonly reported side effects of Nolvadex include hot flashes, vaginal discharge, abnormal menstrual periods, and weight loss. These side effects are typically minor, however, and easily treated. Serious side effects, while rare, should be reported immediately to your healthcare provider. These include signs of an allergic reaction, increase in tumor size or appearance, and depression.
An Introduction to Nolvadex Side EffectsAs with any medicine, side effects are possible with Nolvadex® (tamoxifen citrate); 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 easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Nolvadex. Your healthcare provider can discuss a more complete list of Nolvadex side effects with you.)
