Comments from related studies:
From this study (2 weeks ago):
Triggered when I play golf when the temp is above 78-80 degrees.
From this study (1 month ago):
I have been diagnosed with IBS, but I have reason to believe that maybe taking Allopurinol for the last 8 years for Gout may have some effect on my condition. I understand that 300 mg may be too strong for me. My last uric acid level was 3.1 which is in the normal range...should I reduce my amount of the medication to 1/2? Also, I have not been taking the medication after a meal, but at night before I go to bed. Any advice.
From this study (1 month ago):
Low testosterone in the low 100s

- Allopürinol and achilles tendinitis
I take allopurinol on a purely prophylactic basis, as my father has got gout and kidney stones. Since three months I suffer from achilles tendinitis; I put it down to overload; I am rather heavy and play a lot of tennis, besides moving a lot at work. As always, I tried to "walk through" my weight associated problems, but it did not get any better. Non-compliant, I stopped taking allopurinol for the last three days, and, surprise surprise, the pain is quickly abating, in spite of playing prolonged matches the last three days. I remembered that gyrase inhibitors (e.g. ciprofloxacin) predispose to achilles tendon rupture, a fact that I was personal witness with a female player at our club. So I speculate on a causal link between allopurinol and achilles tendinitis
- Allopurinol for 6-mp metabolism to 6-tgn
I began taking Allopurinol 100mg to help metabolize the Purinethol I have been taking for 6 years for Crohn's disease after a blood test revealed my 6-MMP metabolites were too high and 6-TG were too low. Several published studies show Allopurinol to be helpful for "non-preferential metabolizers" like me, to help shunt the metabolic pathway towards therapeutic 6-TG.
After 1 week of Allopurinol, I had to discontinue the drug due to debilitating nausea, which was worst in the morning.
- Ear pain from allopurinol 100mg
I have just been prescribed 100mg Allopurinol.
1 a day.
I am in my second day of taking these tablets.
I have begun to get get a sudden pain in my ear.
I have never in all my years have ever had such a pain.
I know the only change that has happened around me is taking these tablets.
I have stopped taking these and am awaiting my next appt with my GP.
I do take Arcoxia with paracetemol for pain relief.
- Allopurinol and muscle cramps
Approximately 5 years ago I developed gout and my physician prescribed allopurinol. After a period of time I began to have muscle spasms in the calves of my legs at night. My doctor gave me a prescription for restless leg syndrome, which helped for a short time. I was then given a different prescription when that one no longer helped, and finally a third prescription, which did not work either. The cramps continued to grow more severe and more frequent. I was also having extremely severe cramps in my left hand, to the point that I could not straighten my fingers for several excruciating minutes. Although the cramps in my calves had lessened significantly, my toes were starting to cramp severely.
I stopped taking allopurinol about a month ago, and since then I realized that my hands and toes were cramping less and less, and now it is almost completely gone. I inadvertently stopped the allopurinol and I lost the bottle of pills and didn't realize it until I went to refill my pill box that holds a month's supply divided into daily doses. I searched on the internet and found that muscle problems are not uncommon for some people taking allopurinol.
