Allopurinol
A xanthine oxidase inhibitor that reduces the production of uric acid in the body, used primarily to prevent gout attacks and kidney stones caused by uric acid crystal buildup in joints and the urinary tract. It is also used to prevent elevated uric acid levels during cancer treatment when chemotherapy causes rapid breakdown of cancer cells.

The combination of allopurinol and amoxicillin is associated with a markedly increased incidence of skin rashes (primarily maculopapular), though the rash is usually non-severe and reversible.
Low-dose aspirin reduces the uricosuric effect of allopurinol and may increase uric acid levels, potentially triggering gout flares.
No side effects recorded
