Resumo
Erythromycin markedly raises dihydroergotamine exposure, which can cause ergotism with severe peripheral and cerebral vasospasm and ischemia. This is a labeled contraindication with potent CYP3A4 inhibitors.
O que esta interação significa em palavras simples
Dihydroergotamine and Erythromycin are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Dihydroergotamine belongs to Central Nervous System; Erythromycin belongs to Anti Bacterial.
Por que acontece
Erythromycin inhibits CYP3A4-mediated metabolism of dihydroergotamine.
O que fazer
Do not coadminister; use a non-interacting antibiotic such as azithromycin or a different class. Watch for numbness, cold extremities and ischemia if exposure occurs.
