Antihypoglycemics

Antihypoglycemics raise blood sugar quickly when it falls dangerously low. Glucagon signals the liver to release stored glucose and is used for severe low blood sugar when a person cannot safely eat or drink, such as when unconscious or having a seizure. Nausea and vomiting are common after a dose. It needs glucose stored in the liver to work, so it may fail in people who have not eaten for a long time, and food is given once the person can swallow safely.
