Probenecid is used to treat chronic gout and gouty arthritis. It is used to prevent attacks related to gout, not treat them once they occur. It acts on the kidneys to help the body eliminate uric acid. Probenecid is also used to make certain antibiotics more effective by preventing the body from passing them in the urine.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
Probenecid comes in a tablet to take by mouth. It usually is taken two times a day when prescribed for chronic gout or gouty arthritis and four times a day when prescribed with antibiotics to make them more effective. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take probenecid exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Probenecid may increase the frequency of gout attacks during the first 6 to 12 months that you take it, although it will eventually prevent them. Another drug, such as colchicine, may be prescribed to decrease this effect.
Drink at least six to eight full glasses of water a day while taking probenecid to prevent kidney stones, unless directed to do otherwise by your doctor.
Probenecid may cause an upset stomach. Take with food or antacids.
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
