Methergine is used for:
Preventing and treating bleeding after delivery of a baby. It may also be used for other conditions as determined by your doctor.

- you are allergic to any ingredient in Methergine
- you are pregnant
- you have high blood pressure or blood poisoning
- you are taking an azole antifungal (eg, ketoconazole), delavirdine, certain HIV protease inhibitors (eg, ritonavir), efavirenz, a ketolide antibiotic (eg, telithromycin), a macrolide antibiotic (eg, erythromycin), or a serotonin receptor agonist (eg, sumatriptan)
Contact your doctor or health care provider right away if any of these apply to you.
