Degarelix acetate is primarily used in the treatment of advanced prostate cancer. It works by inhibiting the production of testosterone, which can fuel the growth of prostate cancer cells. This medication is administered as a subcutaneous injection and is often prescribed when other hormonal therapies are not suitable. It provides a rapid reduction in testosterone levels, helping to control the progression of the disease. Degarelix is particularly beneficial for patients who require immediate hormone suppression without the initial surge in testosterone levels that can occur with some other treatments. Regular monitoring and follow-up are essential to manage potential side effects and ensure the effectiveness of the therapy.
