Adults who have advanced breast cancer or advanced prostate cancer may benefit from Zoladex® (goserelin acetate implant). This prescription medication is also beneficial in managing the symptoms of certain gynecological conditions, such as endometriosis.
Zoladex is a type of implant, which is inserted just under the skin of the abdomen (stomach). After it is inserted, this implant gradually releases a controlled amount of medicine as it dissolves. Two strengths of this medicine are available: a 3.6-mg implant (which dissolves over a 4-week period) and a 10.8-mg implant (which dissolves in 12 weeks).
Zoladex works by preventing the testes from making testosterone and the ovaries from making estrogen. This causes the levels of testosterone (in men) and estrogen (in women) to decrease.
