SIDE EFFECTS: Cefadroxil generally is well-tolerated. The most common side effects are:

Patients who have had allergic reactions to other cephalosporins should not take cefadroxil. Additionally, persons allergic to penicillin or one of its derivatives (for example, amoxicillin [Amoxil, Dispermox, Trimox] or ampicillin [Omnipen, Plycillin, Principen]) may also be allergic to cefadroxil, although cefadroxil has been used safely in such patients.

Other important side effects which are serious, but rare include:

  • seizures,
  • severe allergic reactions (anaphylaxis),
  • and reduced platelet or red blood cell counts.

Cefadroxil can alter the normal bacteria in the colon and encourage overgrowth of some bacteria, specifically, Clostridium difficile which causes inflammation of the colon (pseudomembranous colitis). Patients who develop signs of pseudomembranous colitis after starting cefadroxil (diarrhea, fever, abdominal pain, and possibly shock) should contact their physician immediately.
