Hello, LaceyLu! How are you? I'm very sorry about the problem that you're having.

According to the FDA, Allopurinol is used to treat excess uric acid and it has been reported to cause rapid weight gain in a small percentage of people that take it. Other side effects may possibly include sore throat, nausea, dizziness, bruising and joint stiffness.

Have you spoken to your doctor? It might not be the right medication for you to take.

I am on 200 mg a day, I didn't notice until I saw your post, but I have gained 50# in 2 years. I thought I was overeating but I actually eat weather and don't hardly ever eat junk or fast food. I will definitely be bringing this up with my rheumatologist. Ty

I am 60yrs old take 200 mg allopurinol each morning for past two years and have gone from 185 to 203 lbs basically eating the same - if not less because I don't like the weight gain - same amount of exercise - maybe even more walking. What is it about Allopurinol that causes this - is it dangerous - and what do they recommend? Can't find any info online and doctors have no solution. I believe I would have to be on an extremely low calorie diet to lose the weight.

I stopped taking it and have lost 7 lbs in the last three weeks without changing my diet. You try to cure one problem and it gives you another problem! I wonder what Chinese Herbalists would do for Gout??

I started taking this about 18 months ago and have gained 80 pounds. I am now having problems with blood pressure, edema, and almost daily headaches. I kept telling my dr that I'm eating better (1k calories a day) and exercising more but still gaining weight. I started taking phentermine and STILL gained weight (in the past I could drop 10 pounds very easily in 2 weeks while taking it) and tried Truvision too. I had my thyroid checked along with lots of other things. The pharmacy was closed and I didn't get my allopurinol filled.... in 2 days I lost 4 pounds. I have started a chart to make sure that is the source but regardless I was still been getting kidney stones even while taking the meds.
