Abort or prevent vascular headaches, such as migraine, migraine variants, or so-called "histaminic cephalalgia " �
Hypersensitivity to ergotamine or any component of the formulation; peripheral vascular disease; hepatic or renal impairment; coronary artery disease; hypertension; sepsis; ergot alkaloids are contraindicated with strong inhibitors of CYP3A4 (includes protease inhibitors, azole antifungals, and some macrolide antibiotics); pregnancy
Serious and/or life-threatening peripheral ischemia has been associated with the coadministration of ergotamine with potent CYP 3A4 inhibitors, including protease inhibitors and macrolide antibiotics. Because CYP3A4 inhibition elevates the serum levels of ergotamine, the risk for vasospasm leading to cerebral ischemia and/or ischemia of the extremities is increased. Therefore, concomitant use of these medications is contraindicated.
Migraine: Sublingual: 2 mg (1 tablet) under tongue at first sign of migraine, then 2 mg every 30 minutes if needed; maximum dose: 6 mg per 24 hours, 10 mg per week
Not recommended for use in the elderly.
Use is contraindicated in patients with impaired renal function.
Use is contraindicated in patients with impaired hepatic function.

Concerns related to adverse effects:
- Cardiac valvular fibrosis: Ergot alkaloids have been associated with fibrotic valve thickening (eg, aortic, mitral, tricuspid); usually associated with long-term, chronic use.
- Cardiovascular effects: Vasospasm or vasoconstriction can occur, possibly resulting in decreased cerebral blood flow, ECG changes, and hypertension; sustained vasoconstriction may also lead to ischemic colitis, intermittent claudication, aggravation of angina, or precipitation of MI. Do not use is any patient at risk or predisposed to vascular effects of ergot alkaloids.
- Ergotism: Ergot alkaloid use may result in ergotism (intense vasoconstriction) resulting in peripheral vascular ischemia and possible gangrene. Ergotism is usually associated with overdosage or prolonged chronic use; do not exceed dosing guidelines and avoid prolonged administration.
- Pleural/retroperitoneal fibrosis: Rare cases of pleural and/or retroperitoneal fibrosis have been reported with prolonged daily use.
Concurrent drug therapy issues:
- CYP3A4 inhibitors: [U.S. Boxed Warning]: Ergot alkaloids are contraindicated with potent inhibitors of CYP3A4 (includes protease inhibitors, azole antifungals, and some macrolide antibiotics); concomitant use associated with acute ergot toxicity (ergotism).
Special populations:
- Elderly: Avoid use in the elderly due to the vasoconstrictive properties and cardiovascular adverse effects associated with ergot alkaloids.
Other warnings/precautions:
- Withdrawal: Discontinuation after extended use may result in withdrawal symptoms (eg, rebound headache).

- Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
- Patient may experience nausea or vomiting. Have patient report immediately to prescriber angina, shortness of breath, bradycardia, tachycardia, arrhythmia, edema, severe dizziness, passing out, severe headache, muscle pain, muscle weakness, change in color of hands or feet from pale to blue or red, burning or numbness of hands or feet, or wounds on fingers or toes (HCAHPS).
- Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
