Eligard (leuprolide acetate) is an injectable suspension injected under your skin (subcutaneously) once every month or once every 3, 4 or 6 months, based on the dosing schedule that works best for you. Your doctor will give you this injection in the doctor’s office, a clinic or in the hospital. It is used for the palliative treatment of advanced prostate cancer.

The medicine is injected into an area around your stomach (abdomen), upper buttocks, or other area with adequate subcutaneous tissue. Your doctor may rotate your injection sites, injecting it into a different area.

Eligard injection forms a solid drug delivery depot under the skin and the medicine is slowly released over time. This means you may not need to get a shot every day or even every month. You may feel a small bump under your skin after you receive the injection, but this will diminish over time. Your doctor may rotate your injection sites.

Leuprolide acetate, the generic name for Eligard, is classified as a gonadotropin releasing hormone (GnRH) agonist and is often referred to as hormone therapy. Eligard works in prostate cancer by reducing the amount of testosterone in men to relieve symptoms, but it is not a cure for prostate cancer.

Follow all your directions for Eligard and read all medication guides or instruction sheets given to you by your healthcare providers.
