Facts About This Drug [top]
Probenecid helps to prevent gout attacks. Gout occurs when you have high levels of uric acid in your body, and an attack occurs when crystals of uric acid form in your joints and your body releases chemicals in response to the crystals. This causes pain and inflammation. Probenecid works by causing more uric acid to leave your body through the kidneys, thereby lowering the level of uric acid in your blood.

Probenecid helps to prevent gout attacks. Gout occurs when you have high levels of uric acid in your body, and an attack occurs when crystals of uric acid form in your joints and your body releases chemicals in response to the crystals. This causes pain and inflammation. Probenecid works by causing more uric acid to leave your body through the kidneys, thereby lowering the level of uric acid in your blood.
Probenecid will not relieve a gout attack that has already started. If you are taking probenecid, keep taking it during an attack, even if another drug is prescribed to treat the attack.
After you start using probenecid, you may still have gout attacks for a while. Keep taking the drug. If you take it regularly, the attacks gradually will become less frequent and less painful, and they may stop completely after several months.
Probenecid can increase your risk of getting kidney stones. To help prevent kidney stones while using probenecid, drink at least 10 to 12 full glasses (eight ounces each) of fluid each day, unless your doctor tells you otherwise. Too much vitamin C also increases your risk of kidney stones, so do not take vitamin C supplements while taking probenecid unless you have checked with your doctor.
