DRUG INTERACTIONS: Probenecid blocks excretion of some drugs by the kidney and, therefore, may increase blood levels and side effects of methotrexate (Rheumatrex, Trexall) and nonsteroidal antiinflammatory drugs (NSAIDs), for example, ibuprofen (Advil), naproxen (Aleve), indomethacin (Indocin), ketorolac (Toradol) and others. Aspirin may reduce the action of probenecid through unknown mechanisms.

PREGNANCY: Probenecid has not been adequately studied in pregnant women.

NURSING MOTHERS: Probenecid has not been adequately studied in nursing mothers.

SIDE EFFECTS: Common side effects of probenecid include headache, dizziness, nausea, vomiting, skin rash, sore gums, and fever. Probenecid may cause a flare of gout and kidney stones, and it is not started during an acute attack of gout. Serious but rare side effects include reduced red blood cell counts (anemia), liver damage and severe allergic reactions.
