What is methylergonovine (Methergine)?
Methylergonovine is in a group of drugs called ergot alkaloids. It affects the smooth muscle of a woman's uterus, improving the muscle tone as well as the strength and timing of uterine contractions.
Methylergonovine is used just after a baby is born, to help deliver the placenta (also called the "afterbirth"). It is also used to help control bleeding and to improve muscle tone in the uterus after childbirth.
Methylergonovine may also be used for purposes than those listed in this medication guide.

What is the most important information I should know about methylergonovine (Methergine)?
You should not use methylergonovine during your pregnancy. This medication is to be used only after delivery of your baby.
Do not breast-feed within 12 hours after taking methylergonovine. Methylergonovine may pass into breast milk in small amounts and could affect a nursing baby. In some cases, you will need to use this medication for up to 1 week after your baby is born. You may need to use a breast pump to establish and maintain your milk flow until your methylergonovine treatment is finished. If you use a breast pump during this time, throw out any milk you collect. Do not feed it to your baby.
Seek emergency medical attention if you think you have symptoms of possible methylergonovine overdose, such as nausea, vomiting, stomach pain, numbness or tingling, muscle twitching, feeling light-headed, fainting, shallow breathing, coldness, or seizure (convulsions).
There may be other drugs that can interact with methylergonovine. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
Grapefruit and grapefruit juice may interact with methylergonovine and lead to unwanted side effects. Discuss the use of grapefruit products with your doctor.
