What is cefadroxil, and how does it work (mechanism of action)?
Cefadroxil is an oral antibiotic in the cephalosporin family of drugs, a family that includes cephalexin (Keflex), cefaclor (Ceclor), cefuroxime (Zinacef), cefpodoxime (Vantin), cefixime (Suprax), and many other injectable antibiotics. Cephalosporins stop bacteria from multiplying by preventing bacteria from forming the walls that surround them. The walls are necessary to protect bacteria from their environment and to keep the contents of the bacterial cell together. Bacteria cannot survive without a cell wall. Cephalosporins are most effective when bacteria are actively multiplying and forming cell walls. Cefadroxil is active against many bacteria, including Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus pyogenes, Moraxella catarrhalis, E. coli, Klebsiella, and Proteus mirabilis. The FDA approved cefadroxil in 1977.
Is cefadroxil available as a generic drug?
GENERIC AVAILABLE: Yes

What are the side effects of cefadroxil?
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:
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.
