TRANYLCYPROMINE (Parnate) sulfate, a non-hydrazine monoamine oxidase inhibitor (trans, d,1-2-phenylcyclopropylamine sulfate), is used in the treatment of mental depression. The following adverse reactions have been reported to result from treatment with this drug: restlessness, insomnia, dizziness, headache, anorexia, nausea, epigastric distress, diarrhea, constipation, dermatitis, palpitations, hypertension, photophobia, leg cramps, tachycardia, edema, and hypotension, the latter occurring predominantly in hypertensive patients. Paroxysmal hypertension and severe headache have sometimes been associated with intracranial hemorrhage and death. Such reactions are characterized by a severe occipital headache which may radiate frontally, palpitation, stiffness of the neck, nausea, vomiting, sweating (sometimes with fever or cold, clammy skin), and photophobia. Either tachycardia or bradycardia may occur, and constricting chest pain and dilated pupils have been noted.1,2
