<unk>  is contraindicated in people with: * Severe renal impairment (estimated glomerular filtration rate (eGFR) below 30 ml/min/1.73 m2) * Known hypersensitivity to<unk>  * Acute or chronic<unk> abolic acidosis, including diabetic ketoacidosis (from uncontrolled diabetes), with or without coma Warnings are also given regarding the use of<unk>  in less severe renal impairment, people aged 65 years old or greater, hypoxic states (e.g., acute congestive heart failure), excessive alcohol intake, hepatic impairment, concomitant use of certain drugs (e.g. carbonic anhydrase inhibitors such as topiramate), surgery, and other procedures, or in people having a radiological study with administration of an iodinated contrast agent.<unk>  is recommended to be temporarily discontinued before any procedure involving use of iodinated contrast agents, (such as a contrast-enhanced CT scan or angiogram) due to the increased risk of lactic acidosis resulting from impaired kidney function;<unk>  can be resumed after two days after contrast administration, if renal function is adequate and stable.
