Overview

Explanation

Metformin (Glucophage) will cause the client to be at risk for lactic acidosis if the client take the medication with injection of contrast medium. The contrast medium may affect kidney function, and metformin in the system may increase risk of lactic acidosis. Holding the drug 24 hours prior and 48 hours following the procedure will minimize complications.
