Ergonovine enhances the action of oxytocin, used to still post partum bleeding.

Depending on the local protocol, provocation testing may involve substances such as ergonovine, methylergonovine or acetylcholine.

These include ergotamine, prescribed for migraine headache; and ergonovine, administered to mothers immediately after childbirth to prevent hemorrhage.

Alexander Shulgin in TiHKAL suggests ergonovine is responsible, instead.

The seeds of many species of morning glory contain ergoline alkaloids such as the psychedelic ergonovine and ergine (LSA).

This drug should not be used with the following medications because very serious interactions may occur: ergot alkaloids (e.g., ergonovine), "triptans" (e.g., sumatriptan, frovatriptan).

Ergometrine (other names include ergonovine and d-lysergic acid beta-propanolamide), is an ergoline (and lysergamide) derivative, and one of the primary ergot and morning glory alkaloids .

They include a fungal parasite of barley, ergot, which contains the alkaloids lysergic acid amide (LSA), a precursor to LSD, and ergonovine.

Methylergometrine (other names include methylergonovine, methylergobasin, methergine, and d-lysergic acid 1-butanolamide) is a synthetic analogue of ergonovine, a psychedelic alkaloid found in ergot, and many species of morning glory.

Ergot alkaloids ergometrine (ergobazin, ergonovine), ergotamine and their synthetic derivatives (methylergometrine) are applied against uterine bleeding, and bisindole alkaloids vinblastine and vincristine are antitumor agents.
