  • RxCUI (RxNorm): 996828
Why two NDCs? The FDA registers this code as 51662-1556-2 — a 5-4-1 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the package segment → 51662-1556-02. Same drug, same package — only the format differs.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

🎯 Indications and Usage 37 words ▾

INDICATIONS & USAGE Following delivery of the placenta, for routine management of uterine atony, hemorrhage and subinvolution of the uterus. For control of uterine hemorrhage in the second stage of labor following delivery of the anterior shoulder.

⏱️ Dosage and Administration 66 words ▾

DOSAGE & ADMINISTRATION Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration. Intramuscularly 1 mL, 0.2 mg, after delivery of the anterior shoulder, after delivery of the placenta, or during the puerperium. May be repeated as required, at intervals of 2-4 hours. Intravenously 1 mL, 0.2 mg, administered slowly over a period of no less than 60 seconds. (See WARNINGS.)

⛔ Contraindications 6 words ▾

CONTRAINDICATIONS Hypertension; toxemia; pregnancy; and hypersensitivity.

⚠️ Warnings ~1 min read ▾

WARNINGS General This drug should not be administered I.V. routinely because of the possibility of inducing sudden hypertensive and cerebrovascular accidents. If I.V. administration is considered essential as a lifesaving measure, methylergonovine maleate should be given slowly over a period of no less than 60 seconds with careful monitoring of blood pressure. Intra-arterial or periarterial injection should be strictly avoided.

Caution should be exercised in the presence of impaired hepatic or renal function. Breast-feeding Mothers should not breast-feed during treatment with Methylergonovine Maleate Injection. Milk secreted during this period should be discarded.

Methylergonovine Maleate Injection may produce adverse effects in the breast-feeding infant. Methylergonovine Maleate Injection may also reduce the yield of breast milk. Mothers should wait at least 12 hours after administration of the last dose of Methylergonovine Maleate Injection before initiating or resuming breast-feeding.

Coronary artery disease Patients with coronary artery disease or risk factors for coronary artery disease (e.g., smoking, obesity, diabetes, high cholesterol) may be more susceptible to developing myocardial ischemia and infarction associated with methylergonovine-induced vasospasm. Medication errors Inadvertent administration of Methylergonovine Maleate Injection to newborn infants has been reported. In these cases of inadvertent neonatal exposure, symptoms such as respiratory depression, convulsions, cyanosis and oliguria have been reported.

Usual treatment is symptomatic. However, in severe cases, respiratory and cardiovascular support is required. Methylergonovine Maleate Injection has been administered instead of vitamin K and Hepatitis B vaccine, medications which are routinely administered to the newborn.

Due to the potential for accidental neonatal exposure, Methylergonovine Maleate Injections should be stored separately from medications intended for neonatal administration.

🤒 Adverse Reactions 153 words ▾

ADVERSE REACTIONS The most common adverse reaction is hypertension associated in several cases with seizure and/or headache. Hypotension has also been reported. Abdominal pain (caused by uterine contractions), nausea and vomiting have occurred occasionally.

Rarely observed reactions have included: acute myocardial infarction, transient chest pains, vasoconstriction, vasospasm, coronary arterial spasm, bradycardia, tachycardia, dyspnea, hematuria, thrombophlebitis, water intoxication, hallucinations, leg cramps, dizziness, tinnitus, nasal congestion, diarrhea, diaphoresis, palpitation, rash and foul taste. There have been rare isolated reports of anaphylaxis, without a proven causal relationship to the drug product. Postmarketing Experience The following adverse drug reactions have been derived from post-marketing experience with Methylergonovine Maleate Injection via spontaneous case reports.

Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency, which is therefore categorized as not known. Nervous system disorders Cerebrovascular accident, paraesthesia Cardiac disorders Ventricular fibrillation, ventricular tachycardia, angina pectoris, atrioventricular block

🆘 Overdosage ~1 min read ▾

OVERDOSAGE Symptoms of acute overdose may include: nausea, vomiting, oliguria, abdominal pain, numbness, tingling of the extremities, and rise in blood pressure, in severe cases followed by hypotension, respiratory depression, hypothermia, convulsions, and coma. Because reports of overdosage with methylergonovine maleate are infrequent, the lethal dose in humans has not been established. The oral LD50 (in mg/kg) for the mouse is 187, the rat 93, and the rabbit 4.5.

Several cases of accidental Methylergonovine Maleate Injection in newborn infants have been reported, and in such cases 0.2 mg represents an overdose of great magnitude. However, recovery occurred in all but one case following a period of respiratory depression, hypothermia, hypertonicity with jerking movements, and convulsions. Also, several children 1-3 years of age have accidentally ingested up to 10 tablets (2 mg) with no apparent ill effects.

A postpartum patient took 4 tablets at one time in error and reported paraesthesias and clamminess as her only symptoms. Treatment of acute overdosage is symptomatic and includes the usual procedures of: 1. removal of offending drug by inducing emesis, gastric lavage, catharsis, and supportive diuresis. 2. maintenance of adequate pulmonary ventilation, especially if convulsions or coma develop.

3. correction of hypotension with pressor drugs as needed. 4. control of convulsions with standard anticonvulsant agents. 5. control of peripheral vasospasm with warmth to the extremities if needed.

🧬 Clinical Pharmacology ~2 min read ▾

CLINICAL PHARMACOLOGY Methylergonovine maleate acts directly on the smooth muscle of the uterus and increases the tone, rate, and amplitude of rhythmic contractions. Thus, it induces a rapid and sustained tetanic uterotonic effect which shortens the third stage of labor and reduces blood loss. The onset of action after I.V. administration is immediate; after I.M. administration, 2-5 minutes, and after oral administration, 5-10 minutes.

Pharmacokinetic studies following an I.V. injection have shown that methylergonovine is rapidly distributed from plasma to peripheral tissues within 2-3 minutes or less. The bioavailability after oral administration was reported to be about 60%, with no accumulation after repeated doses. During delivery with intramuscular injection, bioavailability increased to 78%.

Ergot alkaloids are mostly eliminated by hepatic metabolism and excretion, and the decrease in bioavailability following oral administration is probably a result of first-pass metabolism in the liver. Bioavailability studies conducted in fasting healthy female volunteers have shown that oral absorption of a 0.2 mg methylergonovine tablet was fairly rapid, with a mean peak plasma concentration of 3243 ± 1308 pg/mL observed at 1.12 ± 0.82 hours. For a 0.2 mg intramuscular injection, a mean peak plasma concentration of 5918 ± 1952 pg/mL was observed at 0.41 ± 0.21 hours.

The extent of absorption of the tablet, based upon methylergonovine plasma concentrations, was found to be equivalent to that of the I.M. solution given orally, and the extent of oral absorption of the I.M. solution was proportional to the dose following administration of 0.1, 0.2, and 0.4 mg. When given intramuscularly, the extent of absorption of methylergonovine maleate solution was about 25% greater than the tablet. The volume of distribution (VdSS/F) of methylergonovine was calculated to be 56.1 ± 17.0 liters, and the plasma clearance (CLp/F) was calculated to be 14.4 ± 4.5 liters per hour.

The plasma level decline was biphasic, with a mean elimination half-life of 3.39 hours (range 1.5 to 12.7 hours). A delayed gastrointestinal absorption (Tmax about 3 hours) of methylergonovine maleate tablet might be observed in postpartum women during continuous treatment with this oxytocic agent.

⚠️ Precautions ~2 min read ▾

PRECAUTIONS General Caution should be exercised in the presence of sepsis, obliterative vascular disease. Also use with caution during the second stage of labor. The necessity for manual removal of a retained placenta should occur only rarely with proper technique and adequate allowance of time for its spontaneous separation.

Drug Interactions CYP 3A4 Inhibitors (e.g., Macrolide Antibiotics and Protease Inhibitors) There have been rare reports of serious adverse events in connection with the coadministration of certain ergot alkaloid drugs (e.g., dihydroergotamine and ergotamine) and potent CYP 3A4 inhibitors, resulting in vasospasm leading to cerebral ischemia and/or ischemia of the extremities. Although there have been no reports of such interactions with methylergonovine alone, potent CYP 3A4 inhibitors should not be coadministered with methylergonovine.

Examples of some of the more potent CYP 3A4 inhibitors include macrolide antibiotics (e.g., erythromycin, troleandomycin, clarithromycin), HIV protease or reverse transcriptase inhibitors (e.g., ritonavir, indinavir, nelfinavir, delavirdine) or azole antifungals (e.g., ketoconazole, itraconazole, voriconazole). Less potent CYP 3A4 inhibitors should be administered with caution. Less potent inhibitors include saquinavir, nefazodone, fluconazole, grapefruit juice, fluoxetine, fluvoxamine, zileuton, and clotrimazole.

These lists are not exhaustive, and the prescriber should consider the effects on CYP 3A4 of other agents being considered for concomitant use with methylergonovine. CYP 3A4 inducers Drugs (e.g., nevirapine, rifampicin) that are strong inducers of CYP 3A4 are likely to decrease the pharmacological action of Methylergonovine Maleate Injection. Beta-blockers Caution should be exercised when Methylergonovine Maleate Injection is used concurrently with beta-blockers.

Concomitant administration with beta-blockers may enhance the vasoconstrictive action of ergot alkaloids. Anesthetics Anesthetics like halothan and methoxyfluran may reduce the oxytocic potency of Methylergonovine Maleate Injection. Glyceryl trinitrate and other antianginal drugs Methylergonovine maleate produces vasoconstriction and can be expected to reduce the effect of glyceryl trinitrate and other antianginal drugs.

No pharmacokinetic interactions involving other cytochrome P450 isoenzymes are known. Caution should be exercised when Methylergonovine Maleate Injection is used concurrently with other vasoconstrictors, ergot alkaloids, or prostaglandins. Carcinogenesis, Mutagenesis, Impairment of Fertility No long-term studies have been performed in animals to evaluate carcinogenic potential.

The effect of the drug on mutagenesis or fertility has not been determined. Pregnancy Category C Animal reproductive studies have not been conducted with methylergonovine maleate. It is also not known whether methylergonovine maleate can cause fetal harm or can affect reproductive capacity.

Use of methylergonovine maleate is contraindicated during pregnancy because of its uterotonic effects. (See INDICATIONS AND USAGE .) Labor and Delivery The uterotonic effect of methylergonovine maleate is utilized after delivery to assist involution and decrease hemorrhage, shortening the third stage of labor. Nursing Mothers Mothers should not breast-feed during treatment with Methylergonovine Maleate Injection and for at least 12 hours after administration of the last dose.

Milk secreted during this period should be discarded. Pediatric Use Safety and effectiveness in pediatric patients have not been established. Geriatric Use Clinical studies of methylergonovine maleate did not include sufficient number of subjects aged 65 and over to determine whether they respond differently from younger subjects.

Other reported clinical experience has not identified differences in response between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the d… [Excerpted — this section continues on DailyMed.]

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by HF Acquisition Co LLC, DBA HealthFirst. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 1 other package presentation of this same product, including 1 ml (51662-1556-01). Each has its own NDC and its own page — see the package list near the top of this page.
Who lists this product with the FDA?
HF Acquisition Co LLC, DBA HealthFirst is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
