Fegest 200 SR Tablet contains 200mg of natural micronized progesterone, a hormone essential for regulating the menstrual cycle and maintaining pregnancy. This sustained-release formulation ensures a gradual and consistent release of progesterone, helping to stabilize hormone levels over an extended period. Progesterone plays a crucial role in preparing the endometrium for implantation of a fertilized egg and supports early pregnancy by maintaining the uterine lining. Fegest 200 SR is commonly prescribed for conditions such as luteal phase deficiency, irregular menstrual cycles, amenorrhea, and as part of hormone replacement therapy in menopausal women. It is also used in assisted reproductive technology protocols to support embryo implantation and reduce the risk of miscarriage. The natural micronized form enhances absorption and bioavailability compared to synthetic alternatives. Patients should take Fegest 200 SR exactly as directed by their healthcare provider, typically orally with or without food. Common side effects may include dizziness, headache, breast tenderness, or mild gastrointestinal discomfort. It is important to inform the doctor about any history of allergies, blood clots, liver disease, or hormone-sensitive cancers before starting treatment. Regular monitoring and follow-up are recommended to ensure optimal therapeutic outcomes and minimize potential risks.
