Before taking penicillin, tell your doctor or pharmacist if you are also taking probenecid. Probenecid slows down the removal of penicillin from your body, resulting in higher levels of this antibiotic in your bloodstream. For certain types of difficult-to-treat infections, your doctor may prescribe these 2 medications together in order to achieve this effect. Consult your doctor or pharmacist for more details.
