Ergonovine

Ergonovine, also known as ergometrine and lysergic acid propanolamide, is a medication used to cause contractions of the uterus to treat heavy vaginal bleeding after childbirth. It can be used either by mouth, by injection into a muscle, or injection into a vein.

Common side effects include high blood pressure, vomiting, seizures, headache, and low blood pressure. Other serious side effects include ergotism.

Ergonovine was discovered in 1932. It is on the World Health Organization's List of Essential Medicines. Ergonovine is controlled in some countries because it can be used to make the psychedelic druglysergic acid diethylamide (LSD). It is also known to produce psychedelic effects itself at high doses.
