Migranal Patient Information including How Should I Take

What should I discuss with my healthcare provider before using dihydroergotamine nasal (Migranal)?

Do not use this medication if you are allergic to dihydroergotamine or other ergot medicine such as ergotamine (Ergomar, Ergostat, Cafergot, Ercaf, Wigraine), ergonovine (Ergotrate), methylergonovine (Methergine), or methysergide (Sansert).

Do not use dihydroergotamine nasal if you are pregnant or breast-feeding, or if you have:

  • a history of heart disease, angina (chest pain), blood circulation problems, coronary artery disease (hardening of the arteries), or history of a heart attack or stroke;
  • uncontrolled high blood pressure;
  • severe liver or kidney disease;
  • a serious infection called sepsis; or
  • if you have recently had heart or blood vessel surgery (such as bypass surgery).

Using certain medications together with dihydroergotamine can cause even greater decreases in blood flow than dihydroergotamine used alone. A severe decrease in blood flow to the brain and other parts of the body can lead to dangerous side effects. Do not use dihydroergotamine if you are also using any of the following medications:

  • conivaptan (Vaprisol);
  • diclofenac (Arthrotec, Cataflam, Voltaren, Flector Patch, Solareze);
  • imatinib (Gleevec);
  • isoniazid (for treating tuberculosis);
  • an antibiotic such as clarithromycin (Biaxin), dalfopristin/quinupristin (Synercid), erythromycin (E.E.S., EryPed, Ery-Tab, Erythrocin), telithromycin (Ketek), or troleandomycin (Tao);
  • an antifungal medication such as clotrimazole (Mycelex Troche), itraconazole (Sporanox), ketoconazole (Nizoral), or voriconazole (Vfend);
  • an antidepressant such as nefazodone;
  • heart or blood pressure medication such as diltiazem (Cardizem, Dilacor, Tiazac), nicardipine (Cardene), quinidine (Quinaglute, Quinidex, Quin-Release), or verapamil (Calan, Covera, Isoptin, Verelan); or
  • HIV/AIDS medicine such as amprenavir (Agenerase), atazanavir (Reyataz), delavirdine (Rescriptor), fosamprenavir (Lexiva), indinavir (Crixivan), nelfinavir (Viracept), saquinavir (Invirase, Fortovase), or ritonavir (Norvir).

If you have certain conditions, you may need a dose adjustment or special tests to safely use this medication. Before using dihydroergotamine, tell your doctor if you have:

  • breathing problems;
  • high blood pressure;
  • ischemic bowel disease;
  • liver disease;
  • kidney disease; or
  • coronary artery disease (or risk factors that include diabetes, menopause, smoking, being overweight, having high blood pressure or high cholesterol, having a family history of coronary artery disease, being older than 40 and a man, or being a woman who has had a hysterectomy).

FDA pregnancy category X. This medication can cause birth defects. Do not use dihydroergotamine if you are pregnant. Tell your doctor right away if you become pregnant during treatment. Use an effective form of birth control while you are using this medication.

Dihydroergotamine passes into breast milk and may be harmful to a nursing infant. Dihydroergotamine may also decrease milk production. Do not use dihydroergotamine if you are breast-feeding a baby.

How should I use dihydroergotamine nasal (Migranal)?

Use this medication exactly as prescribed by your doctor. Never use more than your prescribed dose of dihydroergotamine nasal. Follow the directions on your prescription label. Tell your doctor if the medicine seems to stop working as well in treating your migraine attacks. Dihydroergotamine is not for daily use.

Dihydroergotamine nasal spray is absorbed quickly through your nasal passages and is for use only in the nose. The nasal spray liquid should not be injected into the body.

Your doctor may want to give your first dose of dihydroergotamine nasal in a hospital or clinic setting to quickly treat any serious side effects that occur.

Dihydroergotamine nasal comes in a bottle (vial) with a nasal sprayer attachment. Do not open the vial and attach the sprayer until you are ready to use the medication. A new vial and sprayer should be used for each new headache episode.

Before using the medication, prime the nasal spray by pumping exactly 4 sprays into the air.

Use the first dose of dihydroergotamine as soon as you notice headache symptoms, or after an attack has already begun. Use one spray in each nostril, and after 15 minutes use a second spray in each nostril, for a total of 4 sprays.

Do not tilt your head back while you are using the nasal spray, and do not sniff through your nose during use or just after use. Throw away the vial and sprayer after you finish using it to treat one headache episode, or no longer than 8 hours after opening the vial.

If you still have migraine symptoms after using a total of 4 sprays, call your doctor before using any more. Do not use more than 6 total sprays of dihydroergotamine nasal in any 24-hour period. Do not use more than 8 total sprays of this medication over a period of 7 days.

If you use dihydroergotamine nasal long-term, your doctor may want to check your heart function periodically using an electrocardiograph or ECG (sometimes called an EKG), a machine that measures electrical activity of the heart. This will help your doctor determine if it is still safe for you to use this medication. Do not miss any scheduled visits to your doctor.

Do not give this medication to anyone else, even if they have the same headache symptoms you have. Dihydroergotamine can be dangerous if it is used to treat headache in a person who has not been diagnosed by a doctor as having true migraine headaches.

Store dihydroergotamine nasal at room temperature away from moisture and heat. Do not refrigerate or freeze the nasal spray. Do not use any stored dihydroergotamine if the expiration date on the label has passed.
