Gestofit 400mg SR Tablet contains natural micronized progesterone, a bioidentical hormone essential for regulating the menstrual cycle and supporting pregnancy. Each tablet delivers 400mg of progesterone in a sustained-release formulation, ensuring a gradual and consistent release of the hormone over an extended period to maintain stable plasma levels. This medication is primarily indicated for hormone replacement therapy in women experiencing progesterone deficiency, such as those with luteal phase insufficiency, amenorrhea, or irregular menstrual cycles. It is also used to support early pregnancy in cases of threatened miscarriage or assisted reproductive technologies like in vitro fertilization (IVF). Progesterone plays a critical role in preparing the endometrium for implantation and maintaining a conducive environment for fetal development. Gestofit 400mg SR Tablet should be administered under medical supervision, with dosage tailored to the individual’s clinical condition. Common side effects may include dizziness, headache, breast tenderness, and mild gastrointestinal disturbances. Patients with a history of hypersensitivity to progesterone or related compounds should avoid this medication. Caution is advised in individuals with hepatic impairment, thromboembolic disorders, or hormone-sensitive cancers. Regular monitoring is recommended to assess therapeutic response and detect any adverse effects promptly.
