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).

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.

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.
