Oral route (Tablet; Tablet, Extended Release)

Lactic acidosis can occur due to metformin accumulation during treatment with linagliptin/metformin hydrochloride, and case reports of death, hypothermia, hypotension, and resistant bradyarrhythmias have been reported. The risk of lactic acidosis is increased with renal impairment, concomitant cationic drugs (eg, topiramate), age 65 years or greater, having a radiological study with contrast, surgery and other procedures, hypoxic states (eg, acute congestive heart failure), excessive alcohol intake, and hepatic impairment. Onset is often subtle with symptoms such as malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Laboratory abnormalities include elevated blood lactate levels (greater than 5 mmol/L), anion gap acidosis (without evidence of ketonuria or ketonemia), an increased lactate/pyruvate ratio, and metformin plasma levels generally greater than 5 mcg/mL. If lactic acidosis is suspected, immediately discontinue therapy, hospitalize patient, and promptly start hemodialysis.
