Cor-9 Injection is used to reduce the risk of premature birth in pregnant women who have previously had a spontaneous preterm delivery, helping the pregnancy continue for longer.
It contains hydroxyprogesterone caproate, a synthetic form of the hormone progesterone. It works by helping keep the womb relaxed and reducing early contractions.
It is given as an injection into the muscle by a doctor or nurse, usually once a week from the second trimester, on a strict schedule.
Tell your doctor about any history of blood clots before use. Report sudden swelling in the legs, breathlessness, chest pain, or unusual vaginal bleeding straight away.
