If you have a sinus infection or community-acquired pneumonia, your healthcare provider may recommend amoxicillin/clavulanate potassium XR. This product contains two different medications: an antibiotic and a beta-lactamase inhibitor that helps amoxicillin work better. Amoxicillin/clavulanate potassium XR is also used occasionally for the prevention of certain infections rather than their treatment (it is not approved for this use, however).

An Introduction to the Uses for Amoxicillin/Clavulanate Potassium XR

Amoxicillin/clavulanate potassium XR (Augmentin XR®) is a prescription antibiotic. It is approved for the treatment of pneumonia and sinus infections. More specifically, it is used to treat community-acquired pneumonia (pneumonia that occurs in people who have not recently been hospitalized); it is not approved for treating hospital-acquired pneumonia.
Amoxicillin/clavulanate potassium XR is approved for treating such infections only when they are caused by certain types of bacteria. Not all bacteria (and no viruses) will respond to this medication. Also, bacteria have different resistance patterns in different regions in the country. This means that some bacteria may be susceptible to amoxicillin/clavulanate potassium XR in certain parts of the country but not in others.
Overuse and inappropriate use of antibiotics can lead to antibiotic resistance. In order to prevent this, broad-spectrum antibiotics, which are active against a wide range of bacteria, should not be used to treat infections that could be treated by an antibiotic with a narrower spectrum of activity. Amoxicillin/clavulanate potassium XR is usually considered a broad-spectrum antibiotic.
