WHY is this medicine prescribed?

Degarelix injection is used to treat advanced prostate cancer (cancer that begins in the prostate [a male reproductive gland]). Degarelix injection is in a class of medications called gonadotropin-releasing hormone (GnRH) receptor antagonists. It works by decreasing the amount of testosterone (a male hormone) produced by the body. This may slow or stop the spread of prostate cancer cells that need testosterone to grow.

HOW should this medicine be used?

Degarelix injection comes as a powder to be mixed with liquid and injected under the skin in the stomach area, away from the ribs and waistline. It is usually injected once every 28 days by a doctor or nurse in a medical facility.

After you receive a dose of degarelix injection, be sure that your belt or waistband does not put pressure on the place where the medication was injected.

Ask your pharmacist or doctor for a copy of the manufacturer's information for the patient.
