PRESCRIPTION DRUG
Dihydroergotamine mesylate nasal spray is indicated for the acute treatment of migraine headaches with or without aura. Dihydroergotamine mesylate nasal spray is not intended for the prophylactic therapy of migraine or for the management of hemiplegic or basilar migraine. There have been a few reports of serious adverse events associated with the coadministration of dihydroergotamine and potent CYP 3A4 inhibitors, such as protease inhibitors and macrolide antibiotics, resulting in vasospasm that led to cerebral ischemia and/or ischemia of the extremities. The use of potent CYP 3A4 inhibitors (ritonavir, nelfinavir, indinavir, erythromycin, clarithromycin, troleandomycin, ketoconazole, itraconazole) with dihydroergotamine is, therefore contraindicated (see WARNINGS: CYP 3A4 Inhibitors) . Dihydroergotamine mesylate nasal spray should not be given to patients with ischemic heart disease (angina pectoris, history of myocardial infarction, or documented silent ischemia) or to patients who have clinical symptoms or findings consistent with coronary artery vasospasm including Prinzmetal's variant angina (see WARNINGS). Because dihydroergotamine mesylate nasal spray may increase blood pressure, it should not be given to patients with uncontrolled hypertension. Dihydroergotamine mesylate nasal spray , 5-HT1 agonists (e.g., sumatriptan), ergotamine-containing or ergot-type medications or methysergide should not be used within 24 hours of each other. Dihydroergotamine mesylate nasal spray should not be administered to patients with hemiplegic or basilar migraine. In addition to those conditions mentioned above, dihydroergotamine mesylate nasal spray is also contraindicated in patients with known peripheral arterial disease, sepsis, following vascular surgery, and severely impaired hepatic or renal function. Dihydroergotamine mesylate nasal spray is contraindicated in patients who have previously shown hypersensitivity to ergot alkaloids. Dihydroergotamine mesylate should not be used with peripheral and central vasoconstrictors because the combination may result in additive or synergistic elevation of blood pressure. Currently available data have not demonstrated drug abuse or psychological dependence with dihydroergotamine. However, cases of drug abuse and psychological dependence in patients on other forms of ergot therapy have been reported. Thus, due to the chronicity of vascular headaches, it is imperative that patients be advised not to exceed recommended dosages.
Dihydroergotamine mesylate nasal spray is available (as a clear, colorless to faintly yellow solution) in 3.5 mL amber glass vials containing 4 mg of dihydroergotamine mesylate. Dihydroergotamine mesylate nasal spray is provided as a package of 8 units, administration instruction sheet, and one package insert. Each unit consists of one vial and one sprayer.
