JANUMET XR

1 Dosing Considerations • The dosage of JANUMET® or JANUMET® XR should be individualized on the basis of the patient’s current regimen, effectiveness, and tolerability while not exceeding the maximum recommended daily dose of 100 mg sitagliptin and 2000 mg metformin hydrochloride.

Dose escalation should be gradual to reduce the gastrointestinal side effects associated with metformin use. Factors that may increase the risk of lactic acidosis should be reviewed before considering initiation of metformin-containing products in patients with renal impairment.

73 m2 is 50 mg and 1000 mg, respectively. • There have been reports of incompletely dissolved JANUMET® XR tablets being eliminated in the feces. If a patient reports seeing tablets in feces, the healthcare provider should assess adequacy of glycemic control (see PATIENT MEDICATION INFORMATION).

If glycemic control is found to be reduced, alternative treatments should be considered. , sulfonylurea), a lower dose of insulin or the insulin secretagogue may be considered to reduce the risk of hypoglycemia (see 7 WARNINGS AND PRECAUTIONS and 8 ADVERSE REACTIONS).

• Concomitant Use with Medication(s) that May Decrease Renal Function Caution should be exercised when using concomitant medication(s) that may decrease renal function (like diuretics, particularly loop diuretics) or may interfere with the disposition of metformin, such as cationic drugs, that are eliminated by renal tubular secretion, due to the increased risk of developing lactic acidosis during co-administration (see 9 DRUG INTERACTIONS).

2 Recommended Dose and Dosage Adjustment JANUMET® is available in the following dosage strengths: • 50 mg sitagliptin/500 mg metformin hydrochloride • 50 mg sitagliptin/850 mg metformin hydrochloride • 50 mg sitagliptin/1000 mg metformin hydrochloride One JANUMET® tablet should be taken orally twice a day with meals to reduce the risk of gastrointestinal side effects associated with metformin use.

Tablets are to be swallowed whole. For the following dosage strengths of JANUMET® XR: • 50 mg sitagliptin/500 mg metformin hydrochloride extended-release tablet • 50 mg sitagliptin/1000 mg metformin hydrochloride extended-release tablet Two JANUMET® XR tablets should be taken orally once a day with a meal preferably in the evening.

3 SERIOUS WARNINGS AND PRECAUTIONS BOX Serious Warnings and Precautions Lactic Acidosis • Lactic acidosis is a rare, but serious, metabolic complication that can occur due to metformin accumulation during treatment with JANUMET® or JANUMET® XR (see 7 WARNINGS AND PRECAUTIONS, Endocrine and Metabolism – Lactic Acidosis).

• Patients should be cautioned against excessive alcohol intake, either acute or chronic, when taking JANUMET® or JANUMET® XR, since alcohol intake potentiates the effect of metformin on lactate metabolism (see 7 WARNINGS AND PRECAUTIONS, Endocrine and Metabolism – Lactic Acidosis).
