Dosage

Metherspan Tablet 125 mcg dosage

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 secondsOrally: One tablet, 0.2 mg, 3 or 4 times daily in the puerperium for a maximum of 1 week.

Side Effects

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.

Precaution

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.

Interaction

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.

Pregnancy & Breastfeeding use

Pregnancy Category C. Animal reproductive studies have not been conducted with Methylergonovine. It is also not known whether methylergonovine maleate can cause fetal harm or can affect reproductive capacity. Use of Methylergonovine is contraindicated during pregnancy because of its uterotonic effects. Breast-feeding: Mothers should not breast-feed during treatment with Methylergonovine. Milk secreted during this period should be discarded. Methylergonovine may produce adverse effects in the breast-feeding infant. Methylergonovine may also reduce the yield of breast milk. Mothers should wait at least 12 hours after administration of the last dose of Methylergonovine before initiating or resuming breast feeding

Contraindication

Hypertension; toxemia; pregnancy; and hypersensitivity.

Special Warning

Pediatric Use: Safety and effectiveness in pediatric patients have not been established.

Acute Overdose

Symptoms of acute overdose may include: nausea, vomiting, oliquria, abdominal pain, numbness, tingling of the extremities, rise in blood pressure, in severe cases followed by hypotension, respiratory depression, hypothermia, convulsions, and coma.
