Probenecid Pharmacology

Patients with G6PD deficiency who are taking probenecid are at increased risk for hemolytic anemia.

In a patient taking probenecid, they need to have adequate kidney function for the drug to work.

GI upset is likely the most common adverse effect of probenecid. It can be given with food.

Probenecid can raise the concentrations of many common antibiotics like penicillins and cephalosporins.

Remember that there are many medications that can oppose the beneficial effects of probenecid. Thiazides, niacin, and some immunosuppressants can raise uric acid.
