Serious and/or life-threatening peripheral ischemia has been associated with the coadministration of ergotamine/caffeine with potent CYP 3A4 inhibitors including protease inhibitors and macrolide antibiotics. Because CYP 3A4 inhibition elevates the serum levels of ergotamine/caffeine, the risk for vasospasm leading to cerebral ischemia and/or ischemia of the extremities is increased. Hence, concomitant use of these medications is contraindicated.
Migraine, moderate to severe, acute treatment (alternative agent):
Note: Contraindicated in patients with coronary artery disease, hypertension, peripheral vascular disease, renal or hepatic disease, or patients who are pregnant or of childbearing potential. May be associated with significant side effects and may worsen nausea and vomiting associated with migraine. Other migraine-specific agents are preferred; ergotamine may be considered in patients with migraine attacks >48 hours or those with frequent headache recurrence (Ref).
Oral: Ergotamine 2 mg/caffeine 200 mg (2 tablets) as a single dose at onset of attack. If symptoms persist or return, may administer ergotamine 1 mg/caffeine 100 mg (1 tablet) every 30 minutes as needed; some experts recommend separating by 1 hour and limiting to 3 repeat doses (Ref). Maximum dose: Ergotamine 6 mg/caffeine 600 mg (6 tablets) per attack; do not exceed ergotamine 10 mg/caffeine 1,000 mg (10 tablets) per week.
Rectal: Ergotamine 2 mg/caffeine 100 mg (1 suppository) as a single dose at onset of attack; if symptoms persist or return, may administer an additional suppository after 1 hour. Maximum dose: Ergotamine 4 mg/caffeine 200 mg (2 suppositories) per attack; do not exceed ergotamine 10 mg/caffeine 500 mg (5 suppositories) per week.
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Use is contraindicated.
Use is contraindicated.
Refer to adult dosing; use caution due to vasoconstrictive properties (Ref).
(For additional information see "Ergotamine and caffeine: Pediatric drug information")
Migraine: Limited data available; efficacy results variable: Note: Not for chronic daily administration. Not a preferred agent; use of ergotamine has largely been replaced by newer agents with improved efficacy and adverse effect profile.
Adolescents:
Oral: Tablets (ergotamine 1 mg/caffeine 100 mg per tablet): Initial dose: 1 or 2 tablets at onset of attack; then 1 tablet every 30 minutes as needed up to 4 additional doses; maximum dose per attack: 6 tablets (ergotamine 6 mg/caffeine 600 mg); maximum weekly dose: 10 tablets/week (ergotamine 10 mg/caffeine 1,000 mg). Note: Some experts have recommended lower maximum doses (maximum dose per attack: ergotamine 3 mg/attack; maximum weekly dose: ergotamine 5 mg/week) in patients <14 years (Ref).
Rectal: Suppository (ergotamine 2 mg/caffeine 100 mg per suppository): Initial: 1/2 suppository (ergotamine 1 mg/caffeine 50 mg) at first sign of an attack; may repeat in 45 minutes if necessary. Maximum dose per attack: 1 suppository (ergotamine 2 mg/caffeine 100 mg)/attack; maximum dose per day: 2 suppositories (ergotamine 4 mg/caffeine 200 mg)/attack; maximum weekly dose: 4 suppositories (ergotamine 8 mg/caffeine 400 mg)/week (Ref).
Dosage adjustment for concomitant therapy: Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
Use is contraindicated in patients with impaired renal function.
Use is contraindicated in patients with impaired hepatic function.

Significant drug interactions exist, requiring dose/frequency adjustment or avoidance. Consult drug interactions database for more information.
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 myocardial infarction. Do not use in any patient at risk or predisposed to vascular effects of ergot alkaloids. In a scientific statement from the American Heart Association, ergotamine has been determined to be an agent that may cause direct myocardial toxicity (magnitude: major) (AHA [Page 2016]).
• 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 administration.
Special populations:
• Older adults: Avoid use in older adults due to the vasoconstrictive properties and cardiovascular adverse effects associated with ergot alkaloids.
Dosage form specific issues:
• Rectal suppositories: Solitary rectal or anal ulcers have occurred rarely when suppositories are used in higher than recommended doses or with continual use of recommended doses for prolonged periods of time. After discontinuation, spontaneous healing occurs within 4 to 8 weeks.
Other warnings/precautions:
• Appropriate use: Do not use for prolonged daily administration; serious adverse effects are associated with long-term continuous use. Use caution and remain within recommended dosage limits.
• Medication-overuse headache/Withdrawal: Discontinuation even after limited use may result in withdrawal symptoms (ie, rebound headache, nausea, vomiting).
