Answer

Dihydroergotamine can be an effective abortive agent. It is commonly given intravenously (IV) or intramuscularly (IM) and may be self-administered; it can also be given intranasally (0.5 mg bilaterally). [20] Dihydroergotamine tends to cause less arterial vasoconstriction than ergotamine tartrate and is more effective when given early in a cluster attack.
