Methylergonovine belongs to a class of drugs called ergot alkaloids. Methylergonovine is used to prevent or treat bleeding from the uterus that can happen after childbirth or an abortion.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

Methylergonovine comes as a tablet to take by mouth three or four times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take methylergonovine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Before taking methylergonovine,

  • tell your doctor and pharmacist if you are allergic to methylergonovine, other ergot alkaloids (Cafergot, Ergostat, Bellergal), or any other drugs.
  • tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially other ergot alkaloids and vitamins.
  • tell your doctor if you have or have ever had high blood pressure or blood vessel, heart, kidney, or liver disease.
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking methylergonovine, call your doctor.

Take the missed dose as soon as you remember it. However, if it is almost time for your next dose, skip the missed dose and continue your dosing schedule. Do not take a double dose to make up for a missed one.

Methylergonovine may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:

  • upset stomach
  • vomiting
  • diarrhea
  • headache
  • bad taste in mouth

If you experience any of the following symptoms, call your doctor immediately:

  • seizures
  • chest pain
  • fast heartbeat
  • difficulty breathing
  • dizziness
  • ringing in the ears
  • leg cramps
  • skin rash

If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration’s (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature, away from light and excess heat and moisture (not in the bathroom).

Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www. upandaway.org

In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can’t be awakened, immediately call emergency services at 911.

Methylergonovine Breastfeeding Warnings

Use of this drug during the colostral phase of lactation is not expected to transfer appreciable amounts of drug to the breastfed infant. According to the manufacturer, there are isolated reports of adverse effects in breast-fed infants whose mothers received this drug for several days including elevated blood pressure, bradycardia, tachycardia, vomiting, diarrhea, restlessness, or clonic cramps. A case-control study has shown a lack of infant side effects. Other studies have shown decreased serum prolactin, milk production, and duration of lactation, especially when used in the immediate postpartum period (effects appear dose-related and more impactful with injected doses than oral). A short course immediately postpartum does not appear to have a detrimental effect on lactation, however, longer courses are best avoided in mothers who wish to breastfeed. If adverse reactions, such as tachycardia, vomiting, diarrhea and agitation are observed in a breastfed infant, this drug should be discontinued.

Breastfeeding is not recommended during use of this drug

After skin application, absorption is not more than 2%. The part of the substance that has entered the systemic circulation is rapidly hydrolyzed to inactive metabolites, which are excreted mainly in the urine. With a single treatment of surfaces affected by pediculosis, the anti-pediculosis effect lasts from 2–3 to 6 weeks (depending on the dosage form used). Effective as an anti-scabies agent.
