Tranylcypromine
"I took Parnate in the hospital.  It's the second most wonderful thing to ever have happened to my brain, after ECT.  But it tried to kill me.  But that was due to a drug interaction.  Don't take a high dose of Parnate (60 mg) with more than 150 mg of trazodone.  I did.  I had two hypertensive crises.  My BP was 208/163.  It was extremely painful.  But I would go back to Parnate in a second, just without the trazodone.  Look up the drugs it interacts with before you take something with it.  I felt cheerful, I started laughing again for the first time in years.  Until the hypertensive stuff happened my team was talking discharge.  And I came in very sick.  Parnate is great."
