MAOIs

Monoamine Oxidase Inhibitors are used for atypical depressions (depressed patients with mixed anxiety and depression and phobic or hypochondriacally features and are clinically characterized as “atypical”, “non endogenous” or "neurotic"

An example is Phenelzine, commercial name Nardil.

The main drawbacks of this class of drugs is that there are dangerous interactions with food or drink containing high levels of tryamine
         e.g. cheeses such as brie, chocolate and chicken livers.
Side effects of mixing the two result in sweating, nausea, vomiting, chest pains and in the most severe cases death.
