摘要
Methylene blue inhibits MAO-A, and combining it with serotonergic drugs such as nortriptyline can cause serotonin syndrome, which may be severe. The FDA has issued a warning on this interaction.
用白話說明這項交互作用的意義
Methylene blue and Nortriptyline 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.
為什麼會發生
MAO-A inhibition by methylene blue added to serotonin reuptake inhibition by nortriptyline.
處置方式
Avoid the combination in non-emergency settings. If methylene blue is urgent, stop the serotonergic drug and monitor for CNS toxicity for up to two weeks or 24 hours after the last methylene blue dose, whichever comes first.
