Fsprogest 300 SR Tablet contains 300 mg 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 critical role in preparing the endometrium for implantation of a fertilized egg and supports early pregnancy by preventing uterine contractions. Fsprogest 300 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 may also be used in assisted reproductive technologies like in vitro fertilization (IVF) to enhance the chances of successful embryo implantation. The natural micronized form improves absorption and bioavailability compared to synthetic alternatives. Patients should follow their healthcare provider’s instructions regarding dosage and duration of treatment. Common side effects may include dizziness, headache, breast tenderness, and mild gastrointestinal discomfort. It is important to inform the doctor of any allergies, existing medical conditions, or concurrent medications to avoid potential interactions. Fsprogest 300 SR should not be used during pregnancy unless specifically directed by a healthcare professional.
