>Some irreversible MAOIs are still used as drugs of last resort in treatment resistant depression, but they are fairly dangerous comparatively.

They're definitely more side-effect & interaction heavy but a lot of providers are unduly afraid of them. The dietary restrictions are pretty overblown unless you're chowing down on artisanal cheese or chugging soy sauce. A lot of the drug interactions aren't absolute either as long as you start very low and monitor closely when going up - I was able to safely take a low dose of adderall when plenty of providers would act like being in the same room as it while on MAOIs causes instant death.
