This medication is used to treat migraine headache attacks. It helps relieve headache pain and other symptoms such as sensitivity to light or sound. Prompt treatment allows you to get back to your normal routine sooner and may decrease your need for other pain medications. This medication is not used to prevent migraines from occurring.
Dihydroergotamine belongs to a class of drugs known as ergot alkaloids. It may work by narrowing the blood vessels in the brain. It may also block other pain pathways in the brain.
How To Use
Read the Patient Information Leaflet provided by your pharmacist before you start using dihydroergotamine and each time you get a refill. If you have any questions, consult your doctor or pharmacist.
Learn all preparation and usage instructions in the product package. If any of the information is unclear, consult your doctor or pharmacist.
This medication comes in individual nasal spray vials. Each vial contains enough medication to treat a single migraine attack. Do not use more than 4 sprays for a single attack. Before using each nasal spray vial, prime the pump by spraying 4 times into the air, away from the face.
The US and Canadian manufacturers recommend: at the first sign of a migraine, spray this medication into the nostrils. Do not inject this medication. Use 1 spray into each nostril. Do not tilt your head back, sniff through your nose, or blow your nose while spraying or immediately after. Use another spray into each nostril 15 minutes after the first sprays, or use as directed by your doctor. After using the medication, you should lie down and relax in a quiet, darkened room. Therefore, the maximum number of sprays you can use for a single attack is 4 sprays (two in each nostril).
The Canadian manufacturer further recommends to not use more than 8 sprays in 24 hours or 24 sprays in 1 week. Your condition will not improve any faster, and your risk of side effects will increase.
The dosage is based on your medical condition and response to treatment. Do not increase your dose or use this drug more often or for longer than prescribed.
This medication works best if it is used as the first signs of the headache occur. If you wait until the headache has worsened, the medication may not work as well. Use only as needed to treat migraine attacks when they occur. It is not meant for long-term daily use.
If you have never used this medication before and you have risk factors for heart disease (see Precautions), you may need to be monitored for rare but serious side effects (such as chest pain) when you take the first dose. Your doctor may ask you to take the first dose in the office.
If you also take "triptan" or other ergot medications (such as sumatriptan, methysergide), wait 24 hours before and after taking dihydroergotamine. Consult your doctor or pharmacist for more details and for advice on how to time your doses of these medications.
You should feel some relief within 30 minutes. Tell your doctor if your condition persists or worsens.
