Casodex Side Effects
Hot flashes, pain, and constipation are some of the common side effects of Casodex. However, most people are able to take this cancer medication without any problems; if adverse reactions do occur, they are generally easy to treat. If you develop any potentially serious problems, such as shortness of breath, mood changes, or inability to urinate, contact your healthcare provider right away.
Just like any medicine, Casodex® (bicalutamide) can cause side effects. However, not everyone who takes the medication will have problems. In fact, most people tolerate it quite well. If side effects do occur, in many cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Casodex. Your healthcare provider can discuss a more complete list with you.)
