What is probenecid, and how does it work (mechanism of action)?
Probenecid is an oral drug used for reducing blood uric acid levels in patients with hyperuricemia (high uric acid) and/or. High uric acid can cause attacks of gout and kidney stones. Probenecid prevents attacks of gout by reducing uric acid levels in the blood. It does this by preventing the reabsorption of uric acid by the kidney and increasing its excretion from the body in the urine. Probenecid also blocks excretion by the kidney of penicillin and related antibiotics and is used for increasing the levels of the antibiotics in the blood and increasing their effectiveness when treating infections.
What are the uses for probenecid?
Probenecid is used for the treatment of hyperuricemia associated with gout. It also is used for increasing blood levels of penicillin-type antibiotics (for example, ampicillin and amoxicillin) when treating gonorrhea.
What are the side effects of probenecid?
Common side effects of probenecid include:
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.

What is the dosage for probenecid?
The usual adult dose for hyperuricemia is 500 mg twice daily and the maximum dose is 2 grams daily. When combined with penicillin type antibiotics to treat infections, the usual dose is 500 mg 4 times daily. Patients should drink plenty of water in order to prevent formation of kidney stones and take probenecid with food or antacid to reduce stomach upset.
Which drugs or supplements interact with probenecid?
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.
Is probenecid safe to take if I'm pregnant or breastfeeding?
Probenecid has not been adequately studied in pregnant women.
Probenecid has not been adequately studied in nursing mothers.

How should I keep probenecid stored?
Probenecid should be stored at room temperature, 15 C - 30 C (59 F - 86 F).

STDs in Men Overview
Sexually transmitted diseases (STDs) are infections transmitted during sexual contact. They may be caused by viruses, bacteria, or parasites. STDs in men cause no symptoms or symptoms like
genital burning, itching, sores, rashes, or discharge.
Common infections that are sexually transmitted in men include gonorrhea, chlamydia, syphilis, hepatitis C and B, genital warts, human papillomavirus (HPV), and genital herpes.
Some STDs in men are treatable while others are not. STDs are diagnosed with tests that identify proteins or genetic material of the organisms causing the infection. The prognosis of an STD depends on whether the infection is treatable or not. Use of latex condoms can help reduce the risk of contracting an STD but it does not eliminate the risk entirely.
