DHE-45

DHE-45 (dihydroergotamine mesylate)

DHE-45 (dihydroergotamine mesylate, USP) injectable is for the acute treatment of Migraine with or without aura. Ergotamine preparations are non-triptan Migraine abortives. Injectable medications bypass the gastrointestinal tract, making it appropriate for patients who suffer from nausea and vomiting as a result of migraine, and who may therefore have difficulty with oral treatments. DHE-45 is a migraine-specific serotonin agonist. It attacks migraine at its source by selectively binding to receptors in the brain that regulate the release of serotonin, a chemical thought to play a major role in the development of migraine. As other dihydroergotamine medications, DHE-45 has a potential for rebound headaches, aka medication overuse headaches. Thus, it is recommended that it be used no more than two or three days a week.

DHE-45 was first approved by the FDA in 1946..

Type of medication: Rx, abortive, migraine-specific serotonin agonist.

Precautions:

    • Do not use more than two or three days a week as it can cause medication overuse headache, aka rebound.
    • Drinking alcohol can make Migraines worse or trigger additional Migraines. Avoid alcoholic beverages during headache.
    • Some people feel drowsy or dizzy during or after a migraine attack, or after using DHE-45. As long as you are feeling drowsy or dizzy, do not drive, use machines or do anything else that could be dangerous.
    • Do not use within 24 hours of taking a triptan medication.
       

Pregnancy and Breastfeeding:

    • FDA pregnancy category X. Do not take dihydroergotamine if your are pregnant. Dihydroergotamine can induce uterine contractions, and it can restrict blood flow to the fetus.
