Treatment of Premature Labor
Allylestrenol prevents abnormal contractions of uterus muscles and relaxes them. It widens blood vessels to help increase blood flow and improve circulation to the smooth muscles of the uterus. This prevents premature labor and miscarriage. Take it as prescribed and follow your doctor’s instructions carefully to get maximum benefit.

Treatment of Recurrent miscarriage
Allylestrenol helps to prevent miscarriage in such women who have had such complications in an earlier pregnancy. It improves the thickness of the lining of the uterus (womb) and also attachment of the baby to the uterus. This makes sure that there are no abnormal contractions of the uterus which may lead to premature delivery.

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
