Cyclogest is a medication that contains progesterone, which is a naturally occurring female hormone. It is commonly used in various treatments related to reproductive health, including hormone replacement therapy (HRT), management of menstrual disorders, and support of early pregnancy in women who have a history of recurrent miscarriages. Cyclogest is available in the form of pessaries or suppositories, which can be administered either vaginally or rectally, depending on the condition being treated. By supplementing the body's natural progesterone levels, Cyclogest helps to regulate menstrual cycles, prepare the lining of the uterus for pregnancy, and maintain early pregnancy when progesterone levels are insufficient.
