Primlute is a medication primarily used to treat conditions related to hormone imbalances, particularly in women. It contains a synthetic form of progesterone, which can help regulate menstrual cycles, manage symptoms of menopause, and reduce the risk of endometrial hyperplasia during estrogen replacement therapy. By mimicking the natural hormone, Primlute supports reproductive health and can aid in various gynecological issues. Always consult a healthcare provider for specific uses and potential side effects.
