Examples include azole antifungals (such as ketoconazole, itraconazole), boceprevir, cobicistat, mifepristone, telaprevir, certain antidepressants (such as nefazodone), macrolide antibiotics (such as clarithromycin, erythromycin, troleandomycin), HIV NNRTIs (such as delavirdine), HIV protease inhibitors (such as ritonavir, nelfinavir, indinavir), SSRIs (such as fluoxetine, paroxetine, fluvoxamine), among others.

Uses

Dihydroergotamine is used to treat migraine headaches and cluster headaches. It is not recommended for migraines that affect only one side of the brain (hemiplegic migraine) or the base of the brain/neck area (basilar migraine), or to prevent migraines from occurring.Dihydroergotamine is an ergot medication that helps narrow widened blood vessels in the head, thereby reducing the throbbing effects of these headaches.

How to use Dihydroergotamine MESYLATE Ampul

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.

Inject this medication into a vein, into a muscle, or under the skin as directed by your doctor. Dosage is based on your medical condition and response to treatment. Usually, this medication should be used only as needed. It is not meant for long-term daily use. This medication works best if it is taken as the first signs of the headache occur. If you wait until the headache has worsened, the medication may not work as well.

If your headache returns or you have no relief from the first dose, you may repeat the dose 1 hour after the first dose, but only if instructed to do so by your doctor.

If this medication is given into a muscle or under the skin, a third dose may be given 1 hour after the second dose if needed. Do not use more than 3 milliliters in 24 hours or 6 milliliters in a week.

If this medication is given into a vein, do not use more than 2 milliliters in 24 hours or 6 milliliters in a week.

If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. The solution is normally clear and colorless. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.

Other "ergot" drugs (e.g., ergotamine, methysergide), or "triptan-type" drugs (e.g., sumatriptan) should not be used within 24 hours of this drug.

If you are using drugs for migraine attacks on 10 or more days each month, the drugs may actually make your headaches worse (medication overuse headache). Do not use medications more often or for longer than directed. Tell your doctor if you need to use this medication more often, or if the medication is not working as well, or if your headaches get worse.
