Be Aware

Probenecid may initially increase the frequency of gout attacks during the first 6 to 12 months of use, but it will ultimately help prevent them. Your doctor may prescribe another medication, such as colchicine, to decrease this effect. Inform your doctor about all prescription and nonprescription medications you are currently taking. Additionally, let your doctor know if you have a history of ulcers, kidney stones, kidney disorders, or blood disorders.

If you are pregnant, planning to become pregnant, or breastfeeding, inform your doctor. If you become pregnant while taking probenecid, contact your doctor immediately.

Also, inform your doctor if you are planning to undergo surgery that involves a general anesthetic.

If you are having any urine tests, notify your doctor and the laboratory personnel that you are taking probenecid, as it may affect test results.
