From the Guidelines
Methylergonovine is contraindicated in the treatment of postpartum hemorrhage due to its risk of vasoconstriction and hypertension, making Hemabate a more suitable option. When considering the efficacy of methylergonovine versus Hemabate in postpartum hemorrhage, it's crucial to prioritize the patient's safety and the potential risks associated with each medication. According to the European Society of Cardiology guidelines 1, methylergonovine is contraindicated because of the risk of vasoconstriction and hypertension, which can be life-threatening. Some key points to consider when choosing between these medications include:
- The potential for methylergonovine to cause vasoconstriction and hypertension, making it unsuitable for patients with pre-existing hypertension or preeclampsia
- The use of prostaglandin F analogues, such as Hemabate, as a treatment for postpartum hemorrhage, unless an increase in pulmonary artery pressure is undesirable
- The importance of careful patient selection and monitoring when using these medications to minimize potential side effects and maximize efficacy
- The role of oxytocin as a first-line therapy for postpartum hemorrhage, with Hemabate and other medications used as adjuncts or alternatives in refractory cases. In clinical practice, the choice between methylergonovine and Hemabate should be based on the individual patient's needs and medical history, with a focus on minimizing risks and optimizing outcomes.
From the FDA Drug Label
Methergine®(methylergonovine maleate) is a semi-synthetic ergot alkaloid used for the prevention and control of postpartum hemorrhage. Carboprost tromethamine injection is indicated for the treatment of postpartum hemorrhage due to uterine atony which has not responded to conventional methods of management.
The FDA drug label does not provide a direct comparison of the efficacy of methylergonovine (Methergine) versus carboprost (Hemabate) in the treatment of postpartum hemorrhage.

From the Research
Efficacy of Methargen versus Hemabate in Postpartum Hemorrhage
- There is no direct comparison between methargen and Hemabate (carboprost) in the provided studies.
- However, the studies provide information on the efficacy of different uterotonic agents, including methylergonovine (which is similar to methargen) and carboprost, in the treatment of postpartum hemorrhage.
- According to the study 4, combined therapy with oxytocin and second-line uterotonics such as methylergonovine has an additive or synergistic effect and a greater risk reduction for postpartum hemorrhage prevention compared with oxytocin alone.
- The study 5 suggests that oxytocin is more effective than misoprostol with fewer side effects, and adding misoprostol to oxytocin probably makes little or no difference to effectiveness outcomes, but is associated with more side effects.
- The study 6 states that oxytocin is more effective than misoprostol for prevention and treatment of uterine atony and has fewer adverse effects.
- The study 7 reviews the current role of uterotonic medications, including oxytocin, methylergonovine, carboprost, and misoprostol, in the prevention and treatment of uterine atony, and notes that methylergonovine and carboprost are highly effective second-line agents with severe potential side effects.
- The study 8 discusses the use of prostaglandins, including carboprost, in the treatment of postpartum hemorrhage, and notes that injectable prostaglandins are effective in reducing blood loss but may induce cardiovascular or respiratory side effects.
Uterotonic Agents
- Oxytocin is the first-line agent for the prevention and treatment of postpartum hemorrhage 4, 6, 7.
- Methylergonovine and carboprost are highly effective second-line agents, but have severe potential side effects 7.
- Misoprostol is a useful therapeutic in resource-limited practice environments, but its effectiveness as an adjunct to other uterotonic agents has been called into question 7.
