• Cefaclor, is a semisynthetic cephalosporin antibiotic for oral administration. Cefaclor oral capsule is used to treat bacterial infections. These include infections of the ear, skin, lungs and respiratory tract, throat, tonsils, and urinary tract.
• Cefaclor works by stopping the growth of the bacteria causing your infection. This causes your infection to go away.

• Cefaclor is indicated in the treatment of the following infections when caused by susceptible strains of the designated microorganisms.
• Otitis media caused by Streptococcus pneumoniae, Haemophilus influenzae, staphylococci, and Streptococcus pyogenes.
• Lower respiratory tract infections, including pneumonia, caused by Streptococcus pneumoniae, Haemophilus influenzae, and Streptococcus pyogenes
• Pharyngitis and Tonsillitis, caused by Streptococcus pyogenes

Note: Penicillin is the usual drug of choice in the treatment and prevention of streptococcal infections, including the prophylaxis of rheumatic fever. Cefaclor is generally effective in the eradication of streptococci from the nasopharynx; however, substantial data establishing the efficacy of cefaclor in the subsequent prevention of rheumatic fever are not available at present.
