Tranylcypromine is a non-selective, irreversible MAOI typically reserved for treatment-resistant major depressive disorder. Requires strict dietary restrictions to avoid tyramine-rich foods, which can cause life-threatening hypertensive crisis. Allow adequate washout periods when switching from other antidepressants (typically 2 weeks, but 5 weeks for fluoxetine). Effects persist for days to weeks after discontinuation due to irreversible MAO inhibition. Higher doses may produce stimulant-like effects due to structural similarity to amphetamine.
