Uses of Zoladex Injection
Benefits of Zoladex Injection
In Female infertility
Zoladex 3.6 Injection may be used in fertility treatments to help prepare the body for assisted reproductive techniques. It helps control hormone levels during specific stages of treatment, improving the chances of successful ovulation and embryo implantation.
In Prostate cancer
Zoladex 3.6 Injection is used in men with prostate cancer to slow the growth of cancer cells. It lowers testosterone levels, which helps reduce the size of the tumor and control the spread of the disease, often as part of long-term cancer management.
In Breast cancer
Zoladex 3.6 Injection relieves the symptoms of breast cancer such as breast lumps, bloody discharge from nipple or changes in the shape or texture of the breast. It works by altering the production of those hormones in the body that are essential for the growth and spread of breast cancer. It may also interact with other hormones or have a direct effect on cancer to stop its growth.
In Endometriosis
Zoladex 3.6 Injection helps reduce the pain and discomfort caused by endometriosis. It works by lowering hormone levels that trigger the growth of endometrial tissue outside the uterus, helping shrink the tissue and relieve symptoms like pelvic pain and painful periods.

How Zoladex Injection works
Zoladex 3.6 Injection is a synthetic hormone. In men, it works by reducing the level of testosterone (male hormone) which causes regression of prostate tumor and improves symptoms. In women, it suppresses the level of estradiol (female hormone) which helps treat advanced breast cancer, endometriosis and uterine fibroids. It also reduces the thickness of the endometrium, which is the uterus lining, prior to surgery.
