Renvin tablets contain Allylestrenol, a synthetic progestogen used to support pregnancies at risk of miscarriage or preterm birth. Allylestrenol helps maintain the uterine environment necessary for fetal development by reducing the risk of contractions. It is prescribed in cases where there is a history of miscarriage or premature labor, providing crucial support to ensure the pregnancy progresses to full term, thereby increasing the chances of a successful outcome.Available in PCD pharma franchise and Third Party manufacturing in saturn formulations
