Sintesi

Phenelzine, a nonselective MAOI, taken with codeine can cause serotonin syndrome or an opioid-MAOI reaction with hypertension or hypotension, hyperthermia, agitation, coma and respiratory depression. The reaction can be severe.

Cosa significa questa interazione in parole semplici

Codeine 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.

Codeine belongs to Musculoskeletal; Phenelzine belongs to Central Nervous System.

Livello di evidenza: High

Perché avviene

Irreversible MAO inhibition combined with opioid serotonergic and CNS depressant effects produces serotonin toxicity and exaggerated opioid effects.

Cosa fare

Do not use codeine during or within 14 days after stopping phenelzine. Choose a non-serotonergic analgesic instead.
