Leuprolide is 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).
This medication is given by injection into a muscle by a health care professional as directed by the doctor, usually every 3 months. This product slowly releases the medication into the blood over a 3-month period.

You may notice worsening symptoms of early puberty (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 pain/irritation at the injection site, hot flashes (flushing), increased sweating, night sweats, headache, breast changes, acne/seborrhea, joint/muscle aches, vaginal discomfort/dryness, vaginal bleeding/discharge, or increased weight may occur. If any of these effects last or get worse, tell the doctor or pharmacist promptly.
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.
