Sintesi
Even with intranasal use, systemic exposure to dihydroergotamine is sufficient that strong CYP3A4 inhibition by clarithromycin can cause ergotism, with severe vasospasm and ischemia of extremities and the CNS.
Cosa significa questa interazione in parole semplici
Clarithromycin and Dihydroergotamine intranasal 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.
Perché avviene
Clarithromycin inhibits CYP3A4 and decreases clearance of dihydroergotamine.
Cosa fare
Do not coadminister; use an alternative antibiotic such as azithromycin and advise patients to report cold, numb or painful extremities immediately.
