Methergin Injection belongs to the class of medication called 'ergot alkaloids' or 'uterotonic' primarily used to prevent and stop heavy bleeding (postpartum-third stage of labour bleeding) after childbirth or after a miscarriage in cesarean section. Besides this, it is also used to improve uterine contraction (antepartum) and produce uterine contraction during the third stage of labor (postpartum). Postpartum haemorrhage is heavy bleeding (more than normal) after the birth of the baby.

Methergin Injection contains a semi-synthetic ergot alkaloid 'Methylergometrine', that stimulates uterine muscles and increases the uterus' contractions, thus reducing blood loss. It also increases the effects of a natural substance called prostaglandins (PGs), increasing contractions and producing labour. As a result, these increased uterine contractions help in the child's delivery and substantially reduce excessive uterine bleeding. 

Methergin Injection will be administered by a healthcare professional. Do not self-administer. The most common side effects of Methergin Injection are nausea, vomiting, stomach pain, and mild headache in some cases. Most of these side effects of Methergin Injection do not require medical attention and gradually resolve over time. However, if the side effects are persistent, reach out to your doctor.

If you ever had surgery on the uterus, cesarean, or premature labour, please inform your doctor to avoid any complications. If you have been given prostaglandins, then do not take Methergin Injection; if both medicines are taken together, it can increase the contractions. Methergin Injection should not be used for a prolonged time if the contractions do not increase or have severe pre-eclamptic toxemia (high blood pressure, protein in the urine, and swelling), blood or heart circulation problem. 

Methergin Injection contains a semi-synthetic ergot alkaloid 'Methylergometrine' primarily used to stop heavy bleeding postpartum, i.e. third stage of labour bleeding after childbirth or after a miscarriage in cesarean section. Additionally, it plays a significant role in birth by increasing uterus contractions and inducing labour in pregnant women. Methergin Injection works by stimulating uterine muscles and expanding the uterus' contractions, thus reducing blood loss. It also increases the effects of a natural substance called prostaglandins (PGs), increases the contraction,s and hence induces labour. As a result, these increased uterine contractions help deliver the child and substantially reduce excessive uterine bleeding.

Do not take Methergin Injection if you are allergic to Methergin Injection or any of its ingredients. Increasing the dose of Methergin Injection can be harmful if your womb already has too strong contractions, any obstructions in the pathway that might prevent the delivery or if the baby is not receiving a sufficient oxygen supply. Also, the use of Methergin Injection is not advisable if the baby is wrongly positioned in the birth canal, the baby’s head is too large to fit through the pelvis, the placenta lies near the neck of the womb, the placenta separates from the womb before birth, the womb is over-extended and likely to tear (in case you are carrying more than one baby). If you have been given prostaglandins, do not use Methergin Injection within 6 hours as both medications, if taken together, can increase the contractions. Methergin Injection should not be used for a prolonged time if the contractions do not increase or if you have severe pre-eclamptic toxaemia (high blood pressure, protein in the urine, and swelling) or blood or heart circulation problems.
