What is leuprolide?
Leuprolide overstimulates the body's own production of certain hormones, which causes that production to shut down temporarily. Leuprolide reduces the amount of testosterone in men or estrogen in women.
Leuprolide is used in men to treat the symptoms of prostate cancer (but does not treat the cancer itself). Leuprolide is used in women to treat symptoms of endometriosis (overgrowth of uterine lining outside of the uterus) or uterine fibroids.
Leuprolide is also used to treat precocious (early-onset) puberty in both male and female children.
Leuprolide may also be used for purposes not listed in this medication guide.
Certain brands or strengths of leuprolide are only for men and should not be used by women or children.
Your symptoms may become temporarily worse when you first start using leuprolide. Tell your doctor if this continues for longer than 2 months.
Call your doctor at once if you have a seizure, or unusual changes in mood or behavior.
Do not use if you are pregnant.
Before taking this medicine
You should not use this medicine if you are allergic to leuprolide or similar medicines such as buserelin, goserelin, histrelin, nafarelin, or if you have abnormal vaginal bleeding that has not been checked by a doctor.
Certain brands or strengths of leuprolide are used to treat only men and should not be used in women or children. Always check your medicine to make sure you have received the correct brand and strength.
Leuprolide can cause birth defects. Do not use if you are pregnant. Tell your doctor right away if you become pregnant.
Tell your doctor if you have ever had:
depression, mental illness or psychosis;
a brain tumor or blood vessel disorder;
an electrolyte imbalance (such as low levels of potassium or magnesium in your blood); or
Do not give this medicine to any child without medical advice.
Leuprolide usually causes women to stop ovulating or having menstrual periods. However, you may still be able to get pregnant. Use a condom or diaphragm with spermicide to prevent pregnancy. Leuprolide can make hormonal birth control less effective (birth control pills, injections, implants, skin patches, vaginal rings).
Call your doctor if your periods continue while you are being treated with this medicine.
You should not breast-feed while using this medicine.
How should I use leuprolide?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Different brands or strengths of leuprolide are used to treat different conditions. It is very important that you receive exactly the brand and strength your doctor has prescribed. Always check your medication to make sure you have received the correct brand and type prescribed by your doctor.
Leuprolide is injected under the skin or into a muscle, once every month or once every 3 to 6 months. A healthcare provider can teach you how to properly use the medication by yourself.
Read and carefully follow any Instructions for Use provided with your medicine. Do not use leuprolide if you don't understand all instructions for proper use. Ask your doctor or pharmacist if you have questions.
Your symptoms may become temporarily worse as your hormones adjust to leuprolide. Keep using the medicine as directed, and tell your doctor if your condition is still worse after 2 months of using this medicine.
Leuprolide can have long lasting effects on your body. You may need frequent medical tests while using this medicine and for a short time after your last dose.
