About Decapeptyl Depot Injection

Decapeptyl Depot Injection belongs to the class of 'anti-neoplastic agents', primarily used to treat prostate cancer in men, endometriosis in women and precocious puberty (early puberty) in children. Prostate cancer is the prostate gland's cancer (a small gland under the bladder secretes fluid that nourishes and protects sperm) found only in men. Endometriosis is a disorder in which tissue lining the uterus grows outside the uterine cavity. Precocious puberty occurs when a child's body changes into that of an adult or experiences puberty too soon.

Decapeptyl Depot Injection contains Triptorelin that belongs to the class of gonadotropin-releasing hormone (GnRH) agonists. Triptorelin is a synthetic hormone that acts similar to the GnRH, produced by the hypothalamus gland in the brain. It works by inhibiting the synthesis of the natural male hormone, testosterone in men and oestrogen in women. The lowering of testosterone hormone levels in men helps slows down the growth of cancer cells in prostate cancer.

The common side effects of Decapeptyl Depot Injection include hot flashes, decreased sexual interest, shrinking of the testicles, breast tenderness or swelling, dizziness, headache, flu symptoms, nausea, vomiting, diarrhoea, upset stomach and swelling in legs. These side effects are not familiar to everyone and vary individually. If you notice any side effects that are not manageable, please consult your doctor.

Do not take or stop this medicine, if the doctor did not advise you to do so.
