WARNING: LACTIC ACIDOSIS Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. The onset of metformin-associated lactic acidosis is often subtle, accompanied only by nonspecific symptoms such as malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Metformin-associated lactic acidosis was characterized by elevated blood lactate levels (>5 mmol/Liter), anion gap acidosis (without evidence of ketonuria or ketonemia), an increased lactate/pyruvate ratio; and metformin plasma levels generally >5 mcg/mL [see Warnings and Precautions (5.1) ]. Risk factors for metformin-associated lactic acidosis include renal impairment, concomitant use of certain drugs (e.g., carbonic anhydrase inhibitors such as topiramate), age 65 years old or greater, having a radiological study with contrast, surgery and other procedures, hypoxic states (e.g., acute congestive heart failure), excessive alcohol intake, and hepatic impairment. Steps to reduce the risk of and manage metformin-associated lactic acidosis in these high risk groups are provided in the full prescribing information [see Dosage and Administration (2.2) , Contraindications (4) , Warnings and Precautions (5.1) , Drug Interactions (7) , and Use in Specific Populations (8.6 , 8.7) ]. If metformin-associated lactic acidosis is suspected, immediately discontinue JENTADUETO XR and institute general supportive measures in a hospital setting. Prompt hemodialysis is recommended [see Warnings and Precautions (5.1) ]. WARNING: LACTIC ACIDOSIS See full prescribing information for complete boxed warning. Postmarketing cases of metformin-associated lactic acidosis have resulted in death, hypothermia, hypotension, and resistant bradyarrhythmias. Symptoms included malaise, myalgias, respiratory distress, somnolence, and abdominal pain. Laboratory abnormalities included elevated blood lactate levels, anion gap acidosis, increased lactate/pyruvate ratio; and metformin plasma levels generally >5 mcg/mL. ( 5.1 ) Risk factors include renal impairment, concomitant use of certain drugs, age ≥65 years old, radiological studies with contrast, surgery and other procedures, hypoxic states, excessive alcohol intake, and hepatic impairment. Steps to reduce the risk of and manage metformin-associated lactic acidosis in these high risk groups are provided in the Full Prescribing Information. ( 5.1 ) If lactic acidosis is suspected, discontinue JENTADUETO XR and institute general supportive measures in a hospital setting. Prompt hemodialysis is recommended. ( 5.1 )
Adult Dosing
General dosing
Individualize the starting dosage of JENTADUETO XR based on the patient's current regimen The maximum recommended dosage is 5 mg linagliptin/2,000 mg metformin HCl once daily Take orally once daily with a meal, with gradual dose escalation to reduce the gastrointestinal effects due to metformin Swallow whole; do not split, crush, dissolve, or chew Prior to initiation, assess renal function with estimated glomerular filtration rate (eGFR) Do not use in patients with eGFR below 30 mL/min/1.73 m 2 Initiation is not recommended in patients with eGFR between 30 - 45 mL/min/1.73 m 2 Assess risk/benefit of continuing if eGFR falls below 45 mL/min/1.73 m 2 Discontinue if eGFR falls below 30 mL/min/1.73 m 2 JENTADUETO XR may need to be discontinued at time of, or prior to, iodinated contrast imaging procedures 2.1 RecommendedThe dosage of JENTADUETO XR should be individualized on the basis of both effectiveness and tolerability, while not exceeding the maximum recommended total daily dosage of linagliptin 5 mg and metformin hydrochloride (HCl) 2,000 mg. JENTADUETO XR should be given orally once daily with a meal.
