About your treatment  

Your doctor has ordered the drug goserelin to help treat your illness. This drug is given by injection under the skin in the stomach area, usually every 28 days or every 3 months. The medication is slowly released into your bloodstream over that period.

This medication is used to treat:

• prostate cancer
• endometriosis
• advanced breast cancer in premenopausal and perimenopausal women

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for information.

Goserelin is a synthetic hormone. In men, it stops the production of the hormone testosterone, which may stimulate the growth of cancer cells. In women, goserelin decreases the production of the hormone estradiol (which may stimulate the growth of cancer cells) to levels similar to a postmenopausal state. When the medication is stopped, hormone levels return to normal.

In case of emergency/overdose  

In case of overdose, call your local poison control center at 1-800-222-1222. If the victim has collapsed or is not breathing, call local emergency services at 911.

Special instructions  

• Menstruation should stop in women; call your doctor if your regular menstruation continues.
• Hormone replacement therapy may improve some side effects caused by goserelin, including vaginal dryness and hot flashes. Talk to your doctor about whether you should take hormone replacement therapy.
