allopurinol
Brand names: Allopurinol
# Allopurinol Overview Allopurinol is a medicine used to treat gout and prevent kidney stones by lowering uric acid levels in your body. When you have too much uric acid, it can form crystals in your joints and kidneys, causing pain and other problems. This medication works by reducing the amount of uric acid your body makes. Doctors may prescribe it for people who have gout attacks, high uric acid levels, or certain types of cancer that can cause kidney problems. While allopurinol is helpful for many people, there are important safety things to know. Some antibiotics and water pills can increase your risk of serious skin reactions when taken with allopurinol, so tell your doctor about all medicines you're taking. Never use allopurinol with certain cancer medicines like capecitabine or pegloticase without talking to your doctor first, as they may need to adjust your dose or choose a different medicine. Always follow your doctor's instructions carefully and report any unusual skin rashes, fevers, or side effects right away, especially when you first start taking this medication.
