CompositionMethergin Injection is used to prevent and control heavy bleeding from the womb after childbirth (postpartum haemorrhage). It is a single-ingredient medicine containing methylergometrine (methylergonovine), which belongs to a class of medicines called ergot alkaloids (uterotonics).
This medicine is also used to control bleeding after a miscarriage or abortion, and to help the womb contract and return to its normal size after delivery. It makes the womb contract firmly, which squeezes the blood vessels and reduces bleeding. It is given by a healthcare professional in hospital as an injection into a muscle or a slow injection into a vein.
Your care team will check your blood pressure and bleeding closely after the injection. Resting, drinking fluids and letting the team know how you feel can support your recovery.
Before this injection is given, tell your doctor if you have high blood pressure, pre-eclampsia, heart disease, poor circulation, or liver or kidney disease, and about all other medicines you take, especially certain antibiotics, antifungals and HIV medicines, which can react dangerously with this medicine. Tell your care team straight away if you have chest pain, a severe headache, changes in vision, or cold, numb or painful fingers or toes. Your doctor will decide how long the treatment continues.
