Elevation in cephalin flocculation tests without concurrent changes in other liver function parameters have been noted. Hence, it is recommended that metaxalone be administered with great care to patients with pre-existing liver damage and that serial liver function studies be performed as required.

False-positive Benedict's tests, due to an unknown reducing substance, have been noted. A glucose-specific test will differentiate findings.
