Which drugs or supplements interact with cefprozil?
Probenecid (Benemid) may increase the blood concentration of cefprozil by decreasing excretion of cefprozil by the kidney. This interaction is sometimes used to enhance the effect of cephalosporins.
Combining cefprozil with aminoglycosides (for example, tobramycin) produces additive bacterial killing effects but also may increase the risk of harmful effects to the kidney.
Exenatide (Byetta) may delay or reduce the absorption of cephalosporins. Cephalosporins should be administered one hour before exenatide.
CCefprozil may cause false test results with some tests for sugar in the urine.
