Migranal (dihydroergotamine mesylate) for the treatment of migraine headaches: an introduction
Migranal, a member of the Ergotamine or ergot alkaloids class of medications, is used for treating the acute pain of migraines, but not to prevent migraines. It is also not intended for use of management of hemiplegic migraine or basilar migraine. Migranal, which came to the U.S. market in 1997, has the generic name dihydroergotamine mesylate.
How Migranal works
As with many migraine treatments, doctors and researchers are not completely certain how Migranal works. It narrows the brain’s blood vessels and also works to prevent the release of substances that lead to swelling in the brain.

Every medication works differently in different patients. Based on two Migranal’s studies with 200 patients each, here’s a summary of how many patients found relief from migraine symptoms with the Migranal migraine nasal spray medication compared to an inactive placebo, which is also called a dummy or sham treatment:
- Reduction in headache pain within two hours : Migranal 47% to 61%, Placebo 23% to 33%
- Reduction in headache pain within : Migranal 56% to 70%, Placebo 28% to 35%

Who should not take Migranal
Do not take Migranal if you have a headache that doesn’t feel like your usual migraine, or if you have a tension headache.
People who take triptans or antifungal medications should not take Migranal.
People taking Migranal should be monitored closely for ergotism, which occurs after long-term use or overdosage of drugs in the Ergotamine class. Symptoms include vomiting, abdominal cramps and weak pulse.
Do not take Migranal if you take potent CYP 3 A4 inhibitors including HIV protease inhibitors and macrolide antibiotics, such as clarithromycin (Biaxin) which may increase the risk of insufficient blood flow to the brain (a stroke) or decreased blood supply to the extremities (the limbs).
Also don’t take Migranal if you’re already taking another drug in the Ergotamine class.
If you are pregnant, plan to become pregnant or breastfeeding, you must discuss this with your doctor before taking Migranal.
Your doctor should know if you use tobacco products, have any heart disease risk factors, diabetes, Raynaud’s disease, any condition that impacts your circulation, sepsis, heart or blood vessel surgery, heart attack, kidney, liver, lung or heart disease.
Let your doctor know if you are having surgery and your surgeon should know that you’re taking Migranal.
Do not use Migranal if you have a history or risk factors of certain heart diseases, including a low blood supply to the heart (ischemic heart disease). This includes postmenopausal women, men over age 40, high blood pressure, obesity, high cholesterol, diabetes, smoking or family history of heart disease. For those with heart disease risk factors, it is recommended that the first dose of Migranal be administered under medical supervision while heart functioning is monitoring.
