Susten SR 200mg Tablet 10'S

Introduction About SUSTEN SR 200MG TABLET

Susten SR 200mg Tablet is a progesterone-based medicine commonly recommended for women who need support in maintaining hormonal balance, especially in conditions linked to low progesterone levels. It is often considered in cases such as irregular menstrual cycles, hormonal imbalance, or as part of fertility-related care where progesterone plays a key role. Progesterone is an essential hormone that helps regulate the menstrual cycle and supports the health of the uterine lining. The sustained-release (SR) formulation ensures gradual release of the hormone, helping maintain stable levels throughout the day. 

This medicine is typically suitable for women experiencing symptoms of progesterone deficiency, including irregular or missed periods, or those undergoing medically guided reproductive care. It works by supporting the uterine lining and balancing the effects of estrogen, thereby improving cycle regularity and overall reproductive health. Clinical use of progesterone in gynaecological practice is well established, particularly in managing luteal phase support and hormonal imbalance under medical supervision.

Susten SR 200mg Tablet is usually taken after food, swallowed whole with water, and at a fixed time each day to maintain consistent hormone levels. It is important to follow the exact dose and duration prescribed by the doctor and avoid skipping doses or stopping the medicine abruptly. Women should inform their doctor about any history of liver disorders, blood clots, breast conditions, or unexplained vaginal bleeding before starting this medicine. Caution is also advised when using it alongside other hormonal therapies or medicines that may affect liver enzymes.

During pregnancy, this medicine may be used if prescribed, depending on individual requirements, while breastfeeding use should be guided by a healthcare professional as small amounts may pass into breast milk. Common side effects include dizziness, headache, nausea, breast tenderness, abdominal discomfort, and mild mood changes. These are generally temporary, but any persistent or severe symptoms should be reported. Regular follow-up with a doctor helps ensure safe and appropriate use tailored to individual health needs.
