Resumo
Methylene blue inhibits MAO-A and, with a serotonergic tricyclic such as amitriptyline, can precipitate serotonin syndrome. This has been reported with other serotonergic antidepressants and the risk is labelled.
O que esta interação significa em palavras simples
Amitriptyline and Methylene blue 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.
Por que acontece
MAO-A inhibition by methylene blue combined with serotonin reuptake inhibition by amitriptyline.
O que fazer
Avoid the combination in non-emergency settings. If urgent methylene blue treatment is essential, stop amitriptyline and monitor for serotonin toxicity for up to 2 weeks or until 24 hours after the last methylene blue dose, whichever comes first.
