Dihydroergotamine belongs to a family of medications called ergot alkaloids. It is used to help relieve the pain of migraine Headaches. These medications work by constricting blood vessels in the head. This relieves the dilation (widening) of blood vessels, which is related to migraine headache pain.
Dihydroergotamine is most effective if used at the first sign of a migraine headache with or without aura (warning signs that occur prior to the onset of a migraine headache). It is not effective for other types of headache. Relief is often obtained within one-half hour of using the medication. Extra medication may be given if some relief is not obtained after the initial dose. (See the following section for maximum doses.)
Your doctor may have suggested Migranal (Dihydroergotamine-nasal) for conditions other than those listed in these drug information articles. As well, some forms of Migranal (Dihydroergotamine-nasal) may not be used for all of the conditions discussed here.

The recommended dose of dihydroergotamine is one spray in each nostril (total of 2 sprays) at the first sign or symptom of a migraine headache, or as early as possible after the onset of migraine headache pain. If the migraine has not improved sufficiently after about 15 minutes, one additional spray can be used in each nostril (total of 2 more sprays).
One bottle of dihydroergotamine nasal spray contains 4 sprays. No more than 4 sprays (2 in each nostril, i.e., one bottle) should be used for any migraine attack. No more than 8 sprays (2 bottles) should be used in any 24-hour period. No more then 24 sprays (6 bottles) should be used in any 7-day period.
