Usage Information
Amoxicillin and Clavulanate Potassium Extended Release Tablets is indicated for the treatment of infections in adults and pediatric patients weighing greater than or equal to 40 kg who are able to swallow tablets with:community-acquired pneumonia oracute bacterial sinusitisdue to confirmed, or suspected beta-lactamase-producing pathogens (i.e., H. influenzae, M. catarrhalis, H. parainfluenzae, K. pneumoniae, or methicillin-susceptible S. aureus) and S. pneumoniae with reduced susceptibility to penicillin (i.e., penicillin MICs equal to 2 mcg/mL). Limitations of UseAmoxicillin and Clavulanate Potassium Extended Release Tablets is not indicated for the treatment of infections due to S. pneumoniae with penicillin MICs greater than or equal to 4 mcg/mL. Data are limited with regard to infections due to S. pneumoniae with penicillin MICs greater than or equal to 4 mcg/ mL [see Clinical Studies (14)].UsageTo reduce the development of drug-resistant bacteria and maintain the effectiveness of Amoxicillin and Clavulanate Potassium Extended Release Tablets and other antibacterial drugs, Amoxicillin and Clavulanate Potassium Extended Release Tablets 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.In patients with community-acquired pneumonia in whom penicillin-resistant S. pneumoniae is suspected, bacteriological studies should be performed to determine the causative organisms and their susceptibility when Amoxicillin and Clavulanate Potassium Extended Release Tablets is prescribed. Acute bacterial sinusitis or community-acquired pneumonia due to a penicillin-susceptible strain of S. pneumoniae plus a beta-lactamase-producing pathogen can be treated with another amoxicillin and clavulanate potassium product containing lower daily doses of amoxicillin (i.e., 500 mg every 8 hours or 875 mg every 12 hours). Acute bacterial sinusitis or community-acquired pneumonia due to S. pneumoniae alone can be treated with amoxicillin.
