What is dihydroergotamine injection (D. H. E. 45)?
Dihydroergotamine is in a group of drugs called ergot alkaloids (ER-got AL-ka-loids). It works by narrowing the blood vessels around the brain and affects blood flow patterns that are associated with certain types of headaches.
Dihydroergotamine injection is used to treat a migraine or cluster headache attack. This medication will only treat a headache that has already begun. It will not prevent headaches or reduce the number of attacks.
Dihydroergotamine injection should not be used to treat common tension headaches or any headache that seems to be different from your usual migraine headaches. Dihydroergotamine is not for daily use.
Dihydroergotamine injection may also be used for purposes not listed in this medication guide.

What is the most important information I should know about dihydroergotamine injection (D. H. E. 45)?
This medication can harm an unborn baby or a nursing baby. Do not use if you are pregnant or breast-feeding.
Using certain medications together with dihydroergotamine can cause even greater decreases in blood flow than dihydroergotamine used alone, which can lead to dangerous side effects. Tell your doctor about all other medications you are using.
Also tell your doctor about all of your medical conditions, especially breathing problems, high blood pressure, ischemic bowel disease, liver or kidney disease, or risk factors for heart disease.
Never use more than your prescribed dose of dihydroergotamine. An overdose can be fatal.
