Allopurinol is sometimes given to people who suffer repeated gout attacks, especially when tophi deposits, collections of uric acid crystals, develop. This medicine slows the development of uric acid by inhibiting the activity of certain enzymes. It is given in tablet form and should be taken at the same time (or times) each day with food or liquid to help avoid stomach upset.
