Leuprolide is used to treat advanced prostate cancer in men. It is not a cure. Most types of prostate cancer need the male hormone testosterone to grow and spread. Leuprolide works by reducing the amount of testosterone that the body makes. This helps slow or stop the growth of cancer cells and helps relieve symptoms such as painful/difficult urination. Talk to your doctor about the risks and benefits of treatment.
Leuprolide is also used to stop early puberty (precocious puberty) in children. It helps to delay sexual development (such as growth of the breasts/testicles) and the start of menstrual periods. It also helps slow down early bone growth to increase the likelihood of reaching normal adult height. Leuprolide works by decreasing the amount of sex hormones that a child's body makes (estrogen in girls, testosterone in boys).
In children, the dosage is based on weight and response to treatment. The doctor should consider stopping treatment before age 11 for girls and age 12 for boys. Consult the doctor for details.

If you have prostate cancer that has spread to the spine or caused urinary blockage, you may require closer monitoring by your doctor, especially when you first start treatment. Tell your doctor right away if you have any bone pain, numbness/tingling/weakness of the arms/legs, blood in the urine, painful/difficult urination, unusual weakness, or inability to move.
If you are using this medication to stop early puberty, you may notice worsening symptoms (such as menstrual periods) at the start of treatment. However, you should see an improvement in symptoms usually within 1 to 2 months. Tell the doctor promptly if new or worsened symptoms develop after starting treatment.
Mild burning/pain/bruising at the injection site, hot flashes (flushing), increased sweating, night sweats, tiredness, headache, upset stomach, breast changes, acne, joint/muscle aches, trouble sleeping, reduced sexual interest, vaginal discomfort/dryness, vaginal bleeding, swelling of the ankles/feet, increased urination at night, or dizziness may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.
Infrequently in men, shrinking of the testicles, breast tenderness/swelling, and reduced sexual interest/ability may also occur as a result of lowered testosterone levels. Talk to your doctor if these effects occur.
In girls, when this medication is used regularly, it is expected that the menstrual period will stop or decrease to light bleeding/spotting during the first 2 months. Tell the doctor promptly if regular periods continue after 2 months of treatment with leuprolide.

In adults, leuprolide may weaken your bones and increase your risk for bone loss (osteoporosis) if used for a long time. Before using this medication, tell your doctor or pharmacist if you have osteoporosis or if you have any of the following risk factors for osteoporosis: long-term alcohol use, smoking, family history of osteoporosis and broken bones, use of certain medications (for example, corticosteroids such as prednisone, certain anti-seizure drugs such as phenytoin).
In adults, leuprolide may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using leuprolide, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using leuprolide safely.
