Allopurinol
"Had first attack at age of 20 . Didn't treat it till i was 36 . Was really bad - couldn't work . Constant pain ... .
My dr. Put me on allopurinol about a year ago . First month - it's gotten worse.  But since then I have been completely attack free !!! It's done a miracle for me . I can eat and drink and enjoy life .
Didn't see any side effects ."
