General Information



Product introduction
Pamorelin LA 22.5mg Injection is given as an injection under the skin by a qualified medical professional. Your doctor will decide what dose is necessary and how often you need to take it. This will depend on what you are being treated for and may change from time to time. You should take it exactly as your doctor has advised. Taking it in the wrong way or taking too much can cause very serious side effects. It may take several weeks or months for you to see or feel the benefits but do not stop taking it unless your doctor tells you to.
Hot flashes, weakness, increased sweating, fatigue, back pain, and erectile dysfunction are some very common side effects of this medicine. The long-term use of medicine may cause weakened bones and a reduction in bone mineral density. You are advised to take vitamin D and calcium supplements while taking this medicine. It might cause menstrual periods to stop for a period of 7- 12 weeks, inform your doctor if menstrual bleeding continues even during the treatment.
Before taking this medicine, inform your doctor if you have a history of drinking alcohol, smoking, and osteoporosis. Many other medicines can affect, or be affected by, this medicine so let your healthcare team know all medications you are using. This medicine is not recommended during pregnancy or while breastfeeding. The use of effective contraception by both males and females during treatment is important to avoid pregnancy.
Uses of Pamorelin LA Injection
- Prostate cancer
- Endometriosis
- Precocious puberty (premature puberty)
Benefits of Pamorelin LA Injection
Prostate cancer is a condition where cells in the prostate gland grow uncontrollably. Pamorelin LA 22.5mg Injection helps by lowering certain hormones in the body that fuel the growth of prostate cancer cells. This slows disease progression and helps relieve related symptoms.
Endometriosis is a condition where tissue similar to the lining of the uterus grows outside it, causing pain and irregular periods. Pamorelin LA 22.5mg Injection reduces hormone levels that trigger this growth, helping to lessen pain, bleeding, and other discomforts.
Precocious puberty is when children show signs of puberty earlier than normal. Pamorelin LA 22.5mg Injection works by controlling the release of hormones responsible for early puberty, helping to delay development until the appropriate age and supporting healthy growth.

- Weakness
- Back pain
