To reduce the development of drug-resistant bacteria and maintain the effectiveness of cefdinir capsules and other antibacterial drugs, cefdinir capsules should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Cefdinir capsules are indicated for the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions listed below. Adults and Adolescents Community-Acquired Pneumonia Caused by Haemophilus influenzae , Haemophilus parainfluenzae , Streptococcus pneumoniae , and Moraxella catarrhalis . Acute Exacerbations of Chronic Bronchitis Caused by Haemophilus influenzae , Haemophilus parainfluenzae , Streptococcus pneumoniae , and Moraxella catarrhalis . Acute Maxillary Sinusitis Caused by Haemophilus influenzae , Streptococcus pneumoniae , and Moraxella catarrhalis . NOTE: For information on use in pediatric patients, see Pediatric Use and DOSAGE AND ADMINISTRATION. Pharyngitis/Tonsillitis Caused by Streptococcus pyogenes. NOTE: Cefdinir is effective in the eradication of S. pyogenes from the oropharynx. Cefdinir has not, however, been studied for the prevention of rheumatic fever following S. pyogenes pharyngitis/tonsillitis. Only intramuscular penicillin has been demonstrated to be effective for the prevention of rheumatic fever. Uncomplicated Skin and Skin Structure Infections Caused by Staphylococcus aureus and Streptococcus pyogenes. Pediatric Patients Acute Bacterial Otitis Media Caused by Haemophilus influenzae , Streptococcus pneumoniae , and Moraxella catarrhalis . Pharyngitis/Tonsillitis Caused by Streptococcus pyogenes. NOTE: Cefdinir is effective in the eradication of S. pyogenes from the oropharynx. Cefdinir has not, however, been studied for the prevention of rheumatic fever following S. pyogenes pharyngitis/tonsillitis. Only intramuscular penicillin has been demonstrated to be effective for the prevention of rheumatic fever.
