Adverse reactions to monoamine oxidase inhibitors. Part II. Treatment correlates and clinical management.

From a review of the clinical charts of 198 depressed outpatients, information was extracted on common major treatment emergent side effects associated with phenelzine, tranylcypromine, and imipramine. These included hypertensive reactions, severe orthostatic hypotension, hypomania, significant weight gain, sexual dysfunction, and a residual category of multiple side effects which together culminated in drug discontinuation. In this report, frequency of their occurrence for each drug, level of severity, relation to dose and treatment duration, and physician response at the time the side effect was recorded are described. In addition, procedures found useful in the clinical management of these side effects are discussed.
