Ce que signifie cette interaction, en termes simples

Ergotamine and Letermovir 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.

Ergotamine belongs to Central Nervous System; Letermovir belongs to Anti Virals.

Niveau de preuve: Moderate

Pourquoi elle survient

Letermovir inhibits CYP3A4, reducing the metabolism of ergotamine.
