Leuprolide (Intradermal route, intramuscular route, subcutaneous route)



Brand Names:

Dosage Forms:



Antineoplastic Agent


Luteinizing Hormone Releasing Hormone Agonist

Uses of This Medicine:

Leuprolide injection is a synthetic (man-made) hormone that is similar to a natural hormone that is produced in the brain. It is used to treat a number of medical problems such as:

When given regularly to men, leuprolide decreases testosterone levels. Reducing the amount of testosterone in the body helps treat cancer of the prostate.

When given regularly to women, leuprolide decreases estrogen levels. Reducing the amount of estrogen in the body helps treat endometriosis. Leuprolide will also shrink tumors in the uterus, which decreases vaginal bleeding and helps prevent anemia.

When given regularly to boys and girls who have early puberty, leuprolide slows development of the genital area for both sexes. Leuprolide will also slow breast development in girls. This medicine will delay puberty only as long as the child continues to receive it.

This medicine is available only with your doctor's prescription.

Once a medicine has been approved for marketing for a certain use, experience may show that it is also useful for other medical problems. Although this use is not included in product labeling, leuprolide is used in certain patients with the following medical conditions:
