Product introduction

Luprorin 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.

Decreased libido, increased sweating, fatigue, muscle weakness, and hot flashes 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 Luprorin Injection

Benefits of Luprorin Injection

Prostate cancer
Prostate cancer is a common cancer in men that often depends on testosterone to grow. Luprorin Injection is used to lower testosterone levels, helping to slow or stop the growth of prostate cancer cells. It supports better disease control and improves outcomes when combined with other therapies.
Endometriosis
Endometriosis causes painful growth of uterine-like tissue outside the uterus, leading to chronic pelvic pain and fertility issues. Luprorin Injection helps by reducing estrogen levels, which shrinks the abnormal tissue and relieves symptoms. It improves comfort and quality of life for those affected.
Uterine fibroids
Uterine fibroids are non-cancerous growths in the uterus that can cause heavy bleeding and pelvic discomfort. Luprorin Injection reduces the size of fibroids by lowering hormone levels, easing symptoms and making surgical treatments, if needed, more manageable.
Precocious puberty (premature puberty)
Precocious puberty is early onset puberty in children, which can affect growth and development. Luprorin Injection is used to safely delay puberty until the appropriate age, helping ensure normal physical and emotional development.

Side effects of Luprorin Injection

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them

  • Decreased libido

How to use Luprorin Injection

Your doctor or nurse will give you this medicine. Kindly do not self administer.

How Luprorin Injection works

Luprorin Injection reduces the amount of sex hormones (testosterone in men and estrogen in women). It works by decreasing the blood levels of testosterone in males. Luprorin Injection also acts by shutting off hormones made by the ovaries (female reproductive organs), so the estrogen (one of the hormones that causes females to have periods) level is lowered.

Quick tips

  • Luprorin Injection helps in the treatment of locally advanced or metastatic prostate cancer.
  • It may also be used to treat endometriosis and uterine fibroids.
  • It is given as an injection either under the skin or into a muscle.
  • It may cause dizziness and visual disturbances. Don't drive or do anything that requires mental focus until you know how it affects you.
  • It will cause menstrual periods to stop. Periods will resume 7-12 weeks after the final injection. Consult your doctor if you experience menstrual bleed despite treatment. 
  • Use non-hormonal methods of contraception such as condoms to prevent pregnancy during treatment, as this medicine may be harmful to a developing baby.
  • Long term treatment may lead to bone loss and a higher risk of bone fractures, especially if you are a heavy drinker, a smoker, or have a family history of osteoporosis.
