Dark circles around eyes with allopurinol
I have been taking Allopurinol for about 3 months, starting with 100 MG/day the first week, followed by 200 MG/day the 2nd week and 300 MG/day since tell 3rd week.
Last week I noticed a dark discoloration around both eyes, extending down to my cheekbones. This is not a known side effect of allopurinol, but I wonder if someone can tell me if this drug dilates blood vessels, which might be the cause of the darker color under the thin skin around the eyes.
The discoloration might also be due to aging, as I recently turned 59. But seems to me it appeared much too abruptly to be attributed to aging.
