Allopurinol
gout
"I'd put ZERO, but probably won't show!
2 weeks after taking it I started to itch. PA should have taken me off. 4 weeks after start, my kidneys started to fail. 5 weeks after my face, hands, feet started to swell and flake. 
My Dr.'s investigated and I had a syndrome called DRESS, Drug Rash with Eosinophilia and Systemic Symptoms. Allopurinol is one of a handful of meds that causes DRESS. 
I've also read that it has an 8% mortality rate, which is MUCH too high!"
