Experiences with

Isocarboxazid

. • An allergy to carbidopa, levodopa, or any other part of the medicine • Narrow-angle glaucoma, history of melanoma, unexplained skin spots • Whether you have taken a monoamine oxidase inhibitor (phenelzine, tranylcypromine, isocarboxazid) in the last 14 days

So I insisted I return to Marplan (isocarboxazid), another full MAOI.

Along with tranylcypromine and isocarboxazid, phenelzine is one of the few non-selective and irreversible MAOIs still in widespread clinical use.
