Allopurinol (Aloprim®, Zyloprim®)
Veterinary & Aquatic Services Department, Drs. Foster & Smith

Allopurinol decreases the amount of uric acid produced in the body. It is given to prevent certain types of bladder stones (urate stones). Side effects are rare, but may include vomiting, diarrhea, pale gums, tiredness, or bleeding problems. Consult your veterinarian if your pet experiences these signs while being treated with allopurinol. Follow other recommendations to prevent urate stones such as increasing water intake, feeding special diets, and treating urinary tract infections.
