HelloPharmacist Editorial Team Bottom Line
Methylergonovine is a short-term medication used right after childbirth to help the uterus contract and reduce dangerous bleeding. It's very effective for its purpose, but it requires careful monitoring — especially because it can raise blood pressure and interact with many common medications. Always take it exactly as prescribed and let your care team know about every medication and supplement you use.

📖 Methylergonovine: Patient Information Guide

A plain-language walkthrough of Methylergonovine — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.

🎯What it's used for▾

Methylergonovine is used in the postpartum period to help the uterus contract and prevent or control dangerous bleeding. Here are the supported uses across available products:

  • Management of uterine atony (uterus failing to contract adequately) following delivery of the placenta — supported by Methergine tablets, Methylergonovine Maleate tablets, and Methylergonovine Maleate Injection
  • Management of postpartum hemorrhage (heavy uterine bleeding) after delivery — supported by Methergine tablets, Methylergonovine Maleate tablets, and Methylergonovine Maleate Injection
  • Management of subinvolution of the uterus (when the uterus is slow to shrink back to normal size) — supported by Methergine tablets, Methylergonovine Maleate tablets, and Methylergonovine Maleate Injection
  • Control of uterine hemorrhage during the second stage of labor following delivery of the anterior shoulder — supported by all forms and brands
⚙️How it works▾

Methylergonovine works by directly stimulating the smooth muscle of the uterus. It increases the tone (firmness), rate, and strength of uterine contractions, producing a rapid and sustained clamp-down effect. This tightening of the uterine muscle compresses the blood vessels inside, reducing blood loss and helping complete the third stage of labor more quickly.

💊How it's taken▾

Methylergonovine is available as a tablet taken by mouth and as an injection given by a healthcare provider into a muscle (intramuscular) or, in urgent situations, slowly into a vein (intravenous). The tablet is typically taken several times a day during the postpartum period and is not used for longer than one week. The injection may be given after delivery of the shoulder or placenta and can be repeated at intervals as determined by the care team.

  • The IV injection must always be given slowly — over at least 60 seconds — with blood pressure monitoring; it is not used routinely
  • Postpartum women taking the tablet may experience slower absorption during continued use
  • Always follow your prescriber's exact instructions — do not adjust your dose or schedule on your own
🤒Side effects — in detail▾

The most common side effect is high blood pressure (hypertension), which can sometimes be accompanied by seizures or headache. Other side effects include:

  • Headache
  • Abdominal pain from uterine contractions
  • Nausea and vomiting
  • Low blood pressure (hypotension)
  • Dizziness
  • Leg cramps
  • Rapid or slow heartbeat (tachycardia or bradycardia)
  • Ringing in the ears (tinnitus)

Serious but rare reactions include heart attack, coronary artery spasm, stroke (cerebrovascular accident), ventricular fibrillation, and severe vasospasm (dangerous narrowing of blood vessels). Get emergency help right away if you experience chest pain, severe headache, difficulty breathing, or signs of stroke.

⚠️Warnings & precautions▾
  • Intravenous use carries real risk: Giving methylergonovine through a vein can cause sudden, severe high blood pressure and stroke. IV use is only for life-threatening emergencies and must be given very slowly with blood pressure monitoring.
  • Coronary artery disease risk: People with coronary artery disease or its risk factors (smoking, obesity, diabetes, high cholesterol) are more vulnerable to vasospasm affecting the heart, which can lead to heart attack.
  • Breastfeeding: Methylergonovine Maleate Injection can harm a nursing baby and may reduce milk production. Do not breastfeed during injection treatment; discard pumped milk during this time and wait at least 12 hours after the last dose before nursing.
  • Newborn safety: This injection has been accidentally given to newborns instead of vitamin K or hepatitis B vaccine, with serious consequences. It must be stored completely separately from medications meant for newborns.
  • Liver or kidney problems: Use with caution — tell your provider if you have any impairment of liver or kidney function.
🔀What it interacts with▾

Methylergonovine can interact with several medications in ways that may be dangerous. Key interactions to know about:

  • Strong CYP 3A4 inhibitors (certain HIV medications like ritonavir, indinavir, nelfinavir, saquinavir; macrolide antibiotics like clarithromycin; azole antifungals like ketoconazole, itraconazole, voriconazole; and nefazodone) — must NOT be combined; risk of severe vasospasm affecting the brain or limbs
  • Grapefruit juice — a strong CYP 3A4 inhibitor; should be avoided during treatment
  • Moderate CYP 3A4 inhibitors (fluconazole, fluvoxamine, clotrimazole) — should also be avoided
  • Weak CYP 3A4 inhibitors (chlorzoxazone, cilostazol, ranitidine) — use with caution
  • Strong CYP 3A4 inducers (rifampin, nevirapine) — may reduce methylergonovine's effectiveness
  • Beta-blockers — may intensify blood vessel narrowing when combined
  • Certain anesthetics (halothane, methoxyflurane) — may reduce methylergonovine's uterine-stimulating effect
  • Antianginal drugs (e.g., glyceryl trinitrate/nitroglycerin) — methylergonovine's vasoconstrictive effect may reduce their benefit
  • Other vasoconstrictors, ergot alkaloids, or prostaglandins should also be used with caution

This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.

📋Before taking it▾
  • Do not use if you have high blood pressure (hypertension) — this is a contraindication
  • Do not use if you have toxemia (serious high blood pressure complication of pregnancy) — contraindicated
  • Do not use during pregnancy — it stimulates uterine contractions and is contraindicated
  • Do not use if you have a known allergy (hypersensitivity) to methylergonovine
  • Tell your provider if you have coronary artery disease or risk factors (smoking, obesity, diabetes, high cholesterol) — higher risk of heart-related vasospasm
  • Tell your provider about any liver or kidney problems — caution is needed in these conditions
  • Breastfeeding mothers using the injection should not nurse during treatment; wait at least 12 hours after the last injection dose before resuming breastfeeding
🚑If you take too much▾

Taking too much methylergonovine can cause nausea, vomiting, abdominal pain, numbness and tingling in the hands and feet, and a sudden rise in blood pressure. In severe cases, overdose can lead to dangerously low blood pressure, difficulty breathing, seizures, low body temperature (hypothermia), and coma. Treatment is supportive and focused on managing each symptom — if you suspect an overdose, call 911 or poison control immediately.

📡Pharmacodynamics — effects in the body▾

Methylergonovine produces its effects very quickly after administration. When given intravenously, the onset of action is immediate. After an intramuscular injection, the uterus begins responding within 2 to 5 minutes. When taken by mouth as a tablet, the effect begins within 5 to 10 minutes. The drug induces a firm, sustained uterine contraction that shortens the third stage of labor and significantly reduces postpartum blood loss.

🔬Pharmacokinetics — how your body processes it▾

After an intravenous dose, methylergonovine is rapidly distributed from the bloodstream into body tissues within 2 to 3 minutes. When taken orally, about 60% of the medication is absorbed, with peak blood levels reached in roughly one hour in fasting adults — though postpartum women on continued treatment may absorb it more slowly (peak around 3 hours). The intramuscular injection delivers about 25% more drug into the body compared to the tablet. The medication is primarily broken down and eliminated by the liver, and it clears the body with an average half-life (the time for blood levels to fall by half) of about 3.4 hours.

📦How to store it▾

STORE AND DISPENSE Tablets: Store below 25°C (77°F); in a tight, light-resistant container.

🩺 Pharmacist Counseling Corner

Quick, plain-English answers to the questions patients ask most about Methylergonovine — the kind of thing our pharmacy team would talk through with you at the counter.

What exactly is methylergonovine used for? ▾
It's a medication given right after childbirth to help your uterus contract firmly and stop or prevent heavy bleeding. Sometimes the uterus doesn't tighten up on its own the way it should after delivery — that's called uterine atony — and methylergonovine gives it a strong nudge to do its job. It can be given as a shot in the hospital or as a tablet you take at home for up to a week after delivery.
How should I take the tablet form, and is there anything I should know about timing? ▾
You'll typically take the tablet three or four times a day for up to one week after delivery, as your provider directs. One thing worth knowing: if you're taking it continuously in the postpartum period, your body may absorb it a bit more slowly than usual — that's normal. Don't double up on doses if you miss one; just follow the schedule your provider gave you and reach out to them with any questions.
What side effects should I watch out for? ▾
The most common one is high blood pressure, which can sometimes come with a headache or, in rare cases, a seizure — so let your care team know right away if you develop a sudden bad headache, vision changes, or feel unusual. Abdominal cramping from uterine contractions, nausea, and vomiting can also happen. Chest pain, difficulty breathing, or numbness in your hands and feet are serious signs that need immediate medical attention — don't wait on those.
Are there any medications or foods I should avoid while taking this? ▾
Yes — this is really important. Certain medications can dangerously interact with methylergonovine by causing severe narrowing of blood vessels. These include some HIV medications (like ritonavir, indinavir, saquinavir), certain antibiotics (like clarithromycin), antifungals (like ketoconazole), and some antidepressants (like nefazodone). Grapefruit juice is also on the avoid list. Make sure your provider has a full list of everything you take — including over-the-counter drugs and supplements — before starting methylergonovine.
Can I breastfeed while taking this medication? ▾
It depends on which form you're using. If you're receiving Methylergonovine Maleate Injection, you should not breastfeed during treatment — the medication can pass to your baby through breast milk and may also reduce how much milk you produce. Any milk you pump during treatment should be discarded. You'll need to wait at least 12 hours after your last injection dose before nursing again. Talk to your provider or a lactation consultant so you can plan ahead.
Is there anything about my health history that could make this medication riskier for me? ▾
Yes — a few things matter a lot here. Methylergonovine should not be used if you have high blood pressure or certain serious pregnancy-related conditions involving blood pressure. If you have heart disease or risk factors for it — like smoking, obesity, diabetes, or high cholesterol — you're at higher risk for a rare but serious reaction involving spasm of the heart arteries. Also tell your provider if you have liver or kidney problems, as this medication is processed mainly by the liver and extra caution is needed.
Is Methylergonovine available over the counter? ▾
Methylergonovine is dispensed by prescription according to its FDA labeling, so it isn't sold over the counter. Your prescriber and pharmacist will determine if it's appropriate for you.
When was Methylergonovine first available? ▾
Methylergonovine has been available in the United States since at least 1946, based on FDA approval history (Drugs@FDA) and product marketing records.
Who makes Methylergonovine? ▾
Methylergonovine is supplied by 19 manufacturers listed in the FDA NDC Directory, including Bryant Ranch Prepack, Teva Pharmaceuticals USA, Inc., West-Ward Pharmaceuticals Corp.

How we combine label and product data

HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 10 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.

For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Amneal Pharmaceuticals NY LLC is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
