Effects of drug abuse

  • None

Short-Term Effects

  • See “What Are Side Effects Associated with Using Ergotamine/Caffeine?”

Long-Term Effects

  • See “What Are Side Effects Associated with Using Ergotamine/Caffeine?”

Cautions

  • Ergotism
    • Although ergotism rarely develops even after long-term intermittent use of orally administered ergotamine, do not exceed dosage recommendations
    • Ergotism manifested by intense arterial vasoconstriction, producing signs and symptoms of peripheral vascular ischemia
    • Headache, intermittent claudication, muscle pains, numbness, or coldness and pallor of the digits may occur with chronic intoxication; if the condition is allowed to progress untreated, gangrene can result
    • While most cases result from frank overdosage, some cases involve hypersensitivity
    • There are few reports among patients taking doses within recommended limits or for brief periods
    • Withdrawal symptoms (eg, rebound headache) upon discontinuation are rare; typically reported with long, indiscriminate use
  • Fibrotic complications
    • Retroperitoneal and/or pleuropulmonary fibrosis reported
    • Rare reports of fibrotic thickening of the aortic, mitral, tricuspid, and/or pulmonary valves with long-term, continuous use of ergotamine tartrate and Caffeine
    • Do not use it for the chronic daily administration
  • Drug interaction overview
    • Ergotamine is a CYP3A substrate and inhibitor
    • CYP3A inhibitors
    • Potent inhibitors: Contraindicated owing to risk for acute ergot toxicity (ergotism) characterized by vasospasm and ischemia of the extremities
    • Less potent inhibitors: Although not contraindicated, avoid them if possible owing to the risk for vasospasm

Pregnancy and Lactation

  • Contraindicated; ergotamine elicits oxytocic effects
  • There are no studies on placental transfer or teratogenicity of the combination of ergotamine and Caffeine
  • Labor and delivery
  • Contraindicated in labor and delivery owing to ergotamine’s oxytocic effect, which is maximal in the third trimester
  • Lactation
    • Ergot drugs are known to inhibit prolactin, but there are no reports of decreased lactation with ergotamine/Caffeine
    • Ergotamine is excreted in breast milk and may cause symptoms of vomiting, diarrhea, weak pulse, and unstable blood pressure in nursing infants
    • Owing to the potential serious adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or discontinue the drug, considering the importance of the drug to the mother
