Visanne is a prescription medication used in the treatment of endometriosis, a condition where the tissue that normally lines the inside of the uterus grows outside of it. This can cause pain, heavy periods, and infertility. Visanne contains dienogest, a synthetic form of the hormone progesterone, which helps to reduce the growth of this abnormal tissue and alleviate symptoms. It is taken orally once a day and is suitable for long-term use. Visanne has been shown to be effective in reducing pain and improving quality of life for women with endometriosis. It is important to consult with a healthcare professional before starting Visanne to ensure it is the right treatment for you.
