Résumé

Phenelzine irreversibly inhibits monoamine oxidase, so serotonin is not broken down, and fluvoxamine is an SSRI that increases synaptic serotonin. Together they can precipitate serotonin syndrome with hyperthermia, agitation, clonus and autonomic instability, which can be fatal.

Ce que signifie cette interaction, en termes simples

Fluvoxamine and Phenelzine 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.

Fluvoxamine belongs to Central Nervous System; Phenelzine belongs to Central Nervous System.

Niveau de preuve: High

Pourquoi elle survient

Excess serotonergic activity (MAO inhibition plus serotonin reuptake or receptor effects)

Conduite à tenir

Do not co-administer. Leave at least 14 days after stopping phenelzine before starting fluvoxamine, and at least 14 days after stopping fluvoxamine before starting phenelzine.
