Histrelin acetate implant (Histrelin acetate) — Uses, Dosage, Side Effects & Safety

Drug class: Gonadotropin-Releasing Hormone (GnRH) agonist

Overview

Histrelin acetate implant is a long-acting medication used to treat certain hormone-related conditions. In children, it is commonly prescribed for central precocious puberty (CPP), a condition where puberty starts too early. In adults, it may be used to manage advanced prostate cancer by lowering testosterone levels. The implant works by releasing a steady, controlled amount of histrelin, which reduces the production of sex hormones (testosterone in males, estrogen in females). This helps slow or stop the progression of puberty in children and can shrink or slow the growth of hormone-sensitive tumors in adults. Key points: The implant is placed under the skin (usually in the upper arm) and lasts for about 12 months. It is not a cure but helps manage symptoms and disease progression. Regular follow-up with your healthcare provider is important to monitor effectiveness and side effects.
