phenelzine

For instance, the MAOIs—chiefly isocarboxazid, phenelzine, and tranylcypromine—in general are used only after treatment with tricyclic drugs has proved unsatisfactory, because these drugs’ side effects are unpredictable and their complex interactions are incompletely understood. Fluoxetine often relieves cases of depression that have failed to yield to tricyclics or MAOIs.
