In addition to the treatment of gout, probenecid can also be used as an adjunct therapy to increase the levels and effectiveness of antibiotics.

MethodTaking Probenecid Correctly

Follow your doctor's advice and read the information on the drug packaging label before taking probenecid. Do not increase or decrease the dose without consulting your doctor first.

Probenecid should be taken with food to reduce the risk of stomach upset. Take probenecid regularly at the same time every day for maximum effect.

Drink 6–8 glasses of water to avoid developing kidney stones while taking probenecid. Do not stop taking this medicine when your symptoms improve, unless your doctor tells you to.

If you forget to take your medicine, take probenecid immediately if the time lag with the next dose is not too close. If it is close ignore and do not double the dose.

To reduce the risk of gout attacks later in life, you also need to eat healthy foods. Avoid consuming alcoholic beverages, fizzy drinks, canned fruit, or foods rich in purines, such as organ meats and seafood.

During treatment with probenecid, you may need to have a blood uric acid level test, liver or kidney function tests, or a complete blood count, to monitor the progress of your condition and the effectiveness of the drug.
