Methylergometrine Maleate acts as a uterotonic agent to address bleeding complications related to childbirth.
- Postpartum hemorrhage (prevention): induces uterine contraction to reduce bleeding risk. - Postpartum hemorrhage (treatment): restores uterine tone to stop active bleeding. - Uterine atony: promotes smooth‑muscle contraction to achieve hemostasis.

Serious or Rare Side Effects: - Coronary vasospasm: severe chest pain requiring immediate care. - Myocardial ischemia: reduced heart blood flow. - Pulmonary edema: fluid accumulation in lungs. - Seizures: convulsive episodes. - Anaphylaxis: life‑threatening allergic reaction.
What precautions apply to Methylergometrine Maleate?
Methergin® requires careful consideration of patient health status before use.
