Question: what is the difference between augmentin and augmentin xr?
Answer: Tablets of AUGMENTIN (250 mg or 500 mg) CANNOT be used to provide the same dosages as AUGMENTIN XR Extended Release Tablets. This is because AUGMENTIN XR contains 62.5 mg of clavulanic acid, while the AUGMENTIN 250-mg and 500-mg tablets each contain 125 mg of clavulanic acid.
