Résumé

Citalopram raises synaptic serotonin by blocking reuptake, and isocarboxazid (an irreversible non-selective MAO inhibitor) prevents its breakdown. Serotonin syndrome with agitation, hyperthermia, clonus and autonomic instability can develop, sometimes fatally.

Ce que signifie cette interaction, en termes simples

Citalopram and Isocarboxazid 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.

Citalopram belongs to Central Nervous System; Isocarboxazid belongs to Central Nervous System.

Niveau de preuve: High

Pourquoi elle survient

Serotonin reuptake inhibition combined with MAO inhibition causes excess serotonergic activity

Conduite à tenir

Contraindicated. Wait at least 14 days after stopping isocarboxazid before starting the other drug; allow at least 2 weeks between stopping an irreversible MAOI and starting citalopram, and about a week the other way round.
