Ergotamine and Caffeine Dosage and Administration

Procedure: For the best results, dosage should start at the first sign of an attack. Adults: Take 2 tablets at the start of attack; 1 additional tablet every ½ hour, if needed for full relief (maximum 6 tablets per attack, 10 per week).

Maximum Adult Dosage:

Total daily dose for any one attack should not exceed 6 tablets. Total weekly dosage should not exceed 10 tablets. Ergotamine tartrate and caffeine tablets should not be used for chronic daily administration. In carefully selected patients, with due consideration of maximum dosage recommendations, administration of the drug at bedtime may be an appropriate short-term preventive measure.

Pregnancy Risk Factor X Pregnancy Considerations

Animal reproduction studies have not been conducted with this combination. Ergotamine and caffeine both cross the placenta and may cause prolonged constriction of the uterine vessels and/or increased myometrial tone leading to reduced placental blood flow. Use is contraindicated in pregnant women.
