How does this medication work? What will it do for me?
Probenecid belongs to the class of medications called uricosurics. It is used to treat and prevent gout. It is not useful for treatment of a gout attack that is currently taking place.
It may also be used to increase the levels of certain types of antibiotics in the blood. Probenecid acts by decreasing levels of uric acid, which causes gout, in the blood. It acts on the kidney to pass uric acid in the urine. Probenecid also acts on the kidney to prevent certain antibiotics, such as penicillin, from being passed in the urine.
