Drug Description


Zoladex LA is a medication indicated for the treatment of various conditions, including prostate cancer in men and certain types of breast cancer in pre- and peri-menopausal women.  

Zoladex is a long-acting form of goserelin, a luteinizing hormone-releasing hormone (LHRH) analog. works by suppressing the production of certain hormones, such as testosterone in men and estrogen in women. By reducing the levels of these hormones, it helps to slow down or inhibit the growth of cancer cells in the body. 

Use and Dosage 

Zoladex LA is typically administered as a subcutaneous injection every 4 weeks or every 12 weeks, depending on the specific condition being treated. The injection should be performed by a healthcare professional in a clinical setting to ensure proper administration and minimize any potential risks or complications. Take these injections performed by a qualified healthcare professional within a clinical setting. 

To ensure optimal results, follow your doctor’s instructions regarding the administration of Zoladex LA. If you miss an appointment for your medication, promptly contact your doctor to make arrangements for a rescheduled appointment. 

Dosage adjustments may be necessary based on your medical background, current condition, and how you respond to the treatment. Strictly follow the prescribed dosing schedule and avoid missing any doses.

Regular monitoring and follow-up with a healthcare provider are necessary to assess the effectiveness and monitor for any potential complications. 
  • Breast Cancer: Goserelin may also be used in the treatment of certain types of breast cancer. It is typically used in combination with other medications or therapies.
