For Healthcare Professionals

Applies to tranylcypromine: oral tablet

Cardiovascular

Hypertensive crisis (sometimes fatal) is the most important reaction associated with tranylcypromine therapy and is characterized by some or all of the following symptoms: occipital headache that may radiate frontally, palpitation, neck stiffness or soreness, nausea or vomiting, sweating (sometimes with fever and sometimes with cold, clammy skin), pupil dilatation, photophobia, tachycardia or bradycardia, and constricting chest pain. Hypertensive crises may be precipitated by concomitant administration of sympathomimetic drugs or related compounds, other monoamine oxidase inhibitors, or dibenzazepine-related entities. Ingestion of foods with a high concentration of tyramine may also cause a hypertensive crisis. Blood pressure should be monitored closely in all patients to detect any pressor response. Patients should be observed frequently, as blood pressure readings should not be relied upon completely. Therapy should be discontinued immediately upon the occurrence of palpitation or frequent headaches, as these signs may be prodromal of a hypertensive crisis.

Cardiovascular side effects have included hypertensive crisis, postural hypotension, tachycardia, palpitations, and edema. Intracranial bleeding, which can be fatal, has been reported with the paradoxical increase in blood pressure.

Nervous system

Nervous system side effects have included weakness, drowsiness, tinnitus, numbness, paresthesia, headache without blood pressure elevation, insomnia, dizziness, orthostatic dysregulation, syncope, restlessness, and arterial hypertonia (possibly due to failure in low-tyramine diet). Lowering the dosage may relieve some of these effects. Ataxia, confusion, disorientation, memory loss, and akinesia have been reported during postmarketing experience.

Psychiatric

Psychiatric side effects have included anxiety, agitation, suicidality, and manic symptoms. Some of these effects may be due to overstimulation or excessive therapeutic action and may be relieved by lowering the dosage.

Gastrointestinal

Gastrointestinal side effects have included nausea, dry mouth, diarrhea, abdominal pain, anorexia, and constipation. Lowering the dosage may relieve some of these effects. Fissuring in corner of mouth has been reported during postmarketing experience.

Endocrine

Endocrine side effects have included hypoglycemic episodes and impaired water excretion compatible with the syndrome of inappropriate secretion of antidiuretic hormone (SIADH).

Genitourinary

Genitourinary side effects have included urinary retention, impotence, and retarded ejaculation. Urinary frequency and urinary incontinence have been reported during postmarketing experience.
