Ovestin contains a hormone which is similar to the hormone oestrogen that is produced by the body. Low levels of oestrogen may lead to symptoms such as hot flushes, night sweats and dryness or soreness of the vagina. Ovestin is used to help relieve the vaginal symptoms caused by low levels of oestrogen. This is known as hormone replacement therapy. Ovestin may be used to treat these vaginal problems before and after surgery.
Ovestin helps to treat the symptoms of the menopause but it may also increase the chances of getting certain types of cancers and certain heart or circulatory problems. You and your prescriber will need to weigh up the benefits and risks of you having Ovestin. Once you have started to have hormone replacement therapy your prescriber will review your treatment on a regular basis.
Women who are on hormone replacement therapy will be advised by their prescriber to watch out for any symptoms of breast, endometrial or ovarian cancer. They may be advised to regularly examine their breasts for any changes or lumps or report any unusual vaginal bleeding to their prescriber.
