Medical and Pharmacy Editor:

PRESCRIBED FOR: Cefaclor is effective against susceptible bacteria that cause infections of the middle ear, tonsillitis, throat infections, laryngitis, bronchitis, and pneumonia. It also is used in treating urinary tract infections, and skin infections.

SIDE EFFECTS: Cefaclor is generally well tolerated, and side effects usually are transient. Reported side effects include:

Cefaclor should be avoided by patients with known allergy to cephalosporin type antibiotics. Since cefaclor is chemically related to penicillin, patients allergic to penicillin can have an allergic reaction (sometimes even anaphylaxis) if given cefaclor. Treatment with cefaclor and other antibiotics can alter the normal bacteria flora of the colon and permit overgrowth of C. difficile, a bacteria responsible for pseudomembranous colitis. Patients who develop pseudomembranous colitis as a result of antibiotics treatment can experience diarrhea, abdominal pain, fever, and sometimes even shock.
