What is leuprolide?

Leuprolide injection (Eligard, Lupron Depot) is used to treat the symptoms associated with advanced prostate cancer.

Leuprolide injection (Lupron Depot-PED, Fensolvi) is used in children 2 years of age or older to treat central precocious puberty (CPP; a condition causing girls [usually younger than 8 years of age] and boys [usually younger than 9 years of age] to enter puberty too soon, resulting in faster than normal bone growth and development of sexual characteristics).

Leuprolide injection (Lupron Depot) is used alone or with another medication (norethindrone) to treat endometriosis (a condition in which the type of tissue that lines the uterus [womb] grows in other areas of the body and causes pain, heavy or irregular menstruation [periods], and other symptoms).

Leuprolide injection (Lupron Depot) is also used with other medication to treat anemia (a lower than normal number of red blood cells) caused by uterine fibroids (noncancerous growths in the uterus).

Leuprolide belongs to a class of medications called gonadotropin-releasing hormone (GnRH) agonists. It works by decreasing the amount of certain hormones in the body.

Leuprolide side effects

Get emergency medical help if you have signs of an allergic reaction to leuprolide (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Call your doctor at once if you have a seizure, unusual changes in mood or behavior (crying spells, irritability, restlessness, anger, aggression), severe headaches, ringing in your ears, dizziness, nausea, vision problems, or pain behind your eyes.

Your symptoms may become temporarily worse when you first start using leuprolide, including new or worsening symptoms of sexual development in children. Tell your doctor if this continues for longer than 2 months.

Leuprolide can affect growth in children. Tell your doctor if your child is not growing at a normal rate while using leuprolide.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Do not use leuprolide if you are pregnant. Use effective birth control. Do not use if you have abnormal vaginal bleeding that has not been checked by a doctor.

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.

To make sure leuprolide is safe for you, tell your doctor if you have ever had:

Leuprolide usually causes women to stop ovulating or having menstrual periods. However, you may still be able to get pregnant. Use barrier birth control to prevent pregnancy: condom, diaphragm, cervical cap, or contraceptive sponge.

Call your doctor if your periods continue while you are being treated with leuprolide.

Leuprolide may cause birth defects. Do not use leuprolide if you are pregnant. Tell your doctor if you become pregnant.

Ask a doctor if it is safe to breastfeed while using this medicine.

How should I use leuprolide?

Uae leuprolide as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

There are many brands, strengths, or forms of leuprolide used to treat different conditions. Avoid medication errors by using only the medicine your doctor prescribes.

Leuprolide is usually administered by a healthcare provider.

Leuprolide is injected under the skin or into a muscle, once every month or once every 3 to 6 months. A healthcare provider may teach you how to properly use the medication by yourself.

Your symptoms may become temporarily worse as your hormones adjust to leuprolide. A child using this medicine may have increased signs of puberty (such as vaginal bleeding) during the first weeks of treatment.

You may need frequent medical tests while using leuprolide.

Do not reuse a needle or syringe. Place them in a puncture-proof "sharps" container and dispose of it following state or local laws. Keep out of the reach of children and pets.

Follow all storage instructions provided with leuprolide. Your pharmacist can provide more information about how to store this medicine.

Yes, you may still become pregnant if you are using Lupron Depot. Lupron Depot is not a method of birth control. Even though you may not have a period, unprotected intercourse could result in pregnancy. Lupron Depot can cause harm to an unborn child. You should use a reliable non-hormonal birth control such as condoms, a diaphragm with contraceptive jelly, or a copper IUD to prevent pregnancy. Talk to your doctor about use of birth control before you start treatment with Lupron Depot. Continue reading

No, Firmagon (degarelix) is not the same as Lupron but they are both hormone deprivation treatments that may be used for the treatment of advanced prostate cancer. Firmagon takes a more direct path to testosterone suppression than Lupron. Firmagon is an antagonist that immediately stops testosterone production, preventing a testosterone surge and eliminating the need for any additional therapies. Lupron is an agonist that desensitizes the GnRH receptor but causes an initial surge in testosterone and may require additional medication. Continue reading
