Why is this medication prescribed?
Leuprolide injection (Eligard, Lupron Depot) is used to treat the symptoms associated with advanced prostate cancer. Leuprolide injection (Lupron Depot-PED) is used to treat central precocious puberty (CPP; a condition causing children to enter puberty too soon, resulting in faster than normal bone growth and development of sexual characteristics) in girls usually younger than 8 years of age and in boys usually younger than 9 years of age. Leuprolide injection (Lupron Depot) is used alone or with other medication 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 injection is in a class of medications called gonadotropin-releasing hormone (GnRH) agonists. It works by decreasing the amount of certain hormones in the body.
How should this medicine be used?
Leuprolide injection comes as a long-acting suspension (Lupron) that is injected intramuscularly (into a muscle) by a doctor or nurse in a medical office or clinic and is usually given once a month (Lupron Depot, Lupron Depot-PED) or every 3, 4, or 6 months (Lupron Depot-3 month, Lupron Depot-PED-3 month, Lupron Depot-4 month, Lupron Depot-6 Month). Leuprolide injection also comes as a long-acting suspension (Eligard) that is injected subcutaneously (just under the skin) by a doctor or nurse in a medical office or clinic and is usually given every 1, 3, 4, or 6 months. Your doctor will tell you how long your treatment with leuprolide injection will last. When used in children with precocious puberty, leuprolide injection (Lupron Depot-PED, Lupron Depot-PED-3 month) will likely be stopped by your child’s doctor before 11 years of age in girls and 12 years of age in boys.
If you receive leuprolide long-acting suspension (Eligard) as a subcutaneous injection, you may notice a small bump at the place where the injection was given when you first receive the medication. This bump should eventually go away.
Leuprolide may cause an increase in certain hormones in the first few weeks after injection. Your doctor will monitor you carefully for any new or worsening symptoms during this time.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.

What special precautions should I follow?
Before receiving leuprolide injection,
- Tell your doctor and pharmacist if you are allergic to leuprolide, goserelin (Zoladex), histrelin (Supprelin LA, Vantas), nafarelin (Synarel), triptorelin (Trelstar), any other medications, or any of the ingredients in leuprolide injection. Ask your pharmacist for a list of the ingredients.

Be sure to mention any of the following: certain medications for irregular heartbeat such as amiodarone (Cordarone), disopyramide (Norpace), procainamide (Procanbid), quinidine, and sotalol (Betapace, Betapace AF, Sorine); medications for seizures; or oral steroids such as dexamethasone (Decadron, Dexpak), methylprednisolone (Medrol), and prednisone (Sterapred). Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
