Dihydroergotamine can also be given through a vein (intravenous, or IV) or by an injection in the muscle (intramuscular, or IM) for emergency treatment of a severe cluster headache.
Ergotamine narrows blood vessels in the head (vasoconstriction), which relieves pain by reducing pressure on pain-sensitive structures in the head and scalp that may be associated with cluster headaches. This drug may also affect certain brain chemicals that affect how a person feels pain.
Dihydroergotamine and ergotamine are used to stop a cluster headache. Ergotamine may also be used to prevent cluster headaches during a cluster cycle.

Dihydroergotamine, which is typically given as a shot, may provide rapid relief of a headache. A person may be able to give his or her own shot.
