Luprorin 4mg Injection is used in the treatment of the following:

• Prostate cancer
• Hormone-responsive breast cancer in perimenopausal (around menopause) women
• Endometriosis (a painful illness in which the tissue that normally lines the inside of the uterus grows outside of your uterus)
• Central precocious puberty in children under 10 years (a child’s body begins to change into an adult too soon caused by a release of certain hormones)

Luprorin 4mg Injection causes the pituitary gland's GnRH receptors to become desensitized, which lowers the amount of LH and FSH secreted. In the end, this leads to a decrease in the synthesis of sex hormones, specifically estrogen in females and testosterone in males. This helps to slow the growth of cancer cells, reduce the size of uterine fibroids, and alleviate the symptoms of endometriosis and early onset of puberty.

Inform your healthcare provider about all the medicines you take, including prescription, over-the-counter, nutritional and vitamin supplements, vaccines, and herbal products. Certain medications may interact with Luprorin 4mg Injection may cause undesirable side effects.
