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.
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.

Use this medication regularly to get the most benefit from it. To help you remember, mark your calendar to keep track of when to receive the next dose.
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 beginning 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, increased weight, or mood changes may occur. If any of these effects persist or worsen, tell the doctor or pharmacist promptly.
During the first few weeks of treatment, hormone levels will actually increase before they decrease. This is normal. This may result in a temporary increase in symptoms (for example, menstrual periods in girls) for a few weeks. 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.
