Uses of Alnagest Tablet SR

Benefits of Alnagest Tablet SR

In Female infertility

Alnagest 300mg Tablet SR contains progesterone, a female hormone that is important in the regulation of ovulation and menstruation. It is used to cause menstrual periods in women who have not reached menopause but are not having periods due to a lack of natural progesterone in the body. Progesterone helps to prepare the uterus for pregnancy by causing the uterus lining (endometrium) to thicken. This increases the chance of a successful pregnancy. You should use the medicine as prescribed for it to be effective. You may be asked to continue with this treatment for a period after becoming pregnant.

In Hormone replacement therapy

Hormone Placement Therapy (HRT) is a treatment to relieve symptoms of menopause such as hot flushes, night sweats, mood swings, vaginal dryness and reduced sex drive. Since menopause can last for several years, this treatment can make a big improvement to your daily life and mood. You should use this medicine as it is prescribed, and for as long as it is prescribed by your doctor.
