Uses
1 INDICATIONS AND USAGE JANUVIA ® is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. JANUVIA is a dipeptidyl peptidase-4 (DPP-4) inhibitor indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus. ( 1 ) Limitations of Use: • JANUVIA should not be used in patients with type 1 diabetes ( 1 ) • JANUVIA has not been studied in patients with a history of pancreatitis. ( 1 , 5.1 ) Limitations of Use JANUVIA should not be used in patients with type 1 diabetes. JANUVIA has not been studied in patients with a history of pancreatitis. It is unknown whether patients with a history of pancreatitis are at increased risk for the development of pancreatitis while using JANUVIA.
Dosage
2 DOSAGE AND ADMINISTRATION The recommended dose of JANUVIA is 100 mg once daily. JANUVIA can be taken with or without food. ( 2.1 ) Dosage adjustment is recommended for patients with eGFR less than 45 mL/min/1.73 m 2 . ( 2.2 ) Dosage Adjustment in Patients with Renal Impairment ( 2.2 ) eGFR greater than or equal to 30 mL/min/1.73 m 2 to less than 45 mL/min/1.73 m 2 eGFR less than 30 mL/min/1.73 m 2 (including patients with end stage renal disease [ESRD] on dialysis) 50 mg once daily 25 mg once daily 2.1 Recommended Dosing The recommended dose of JANUVIA is 100 mg once daily. JANUVIA can be taken with or without food. 2.2 Recommendations for Use in Renal Impairment Assess renal function prior to initiation of JANUVIA and periodically thereafter.
Side Effects
6 ADVERSE REACTIONS The following adverse reactions are also discussed elsewhere in the labeling: • Pancreatitis [see Warnings and Precautions (5.1) ] • Heart Failure [see Warnings and Precautions (5.2) ] • Acute Renal Failure [see Warnings and Precautions (5.3) ] • Hypoglycemia with Concomitant Use with Insulin or Insulin Secretagogues [see Warnings and Precautions (5.4) ] • Hypersensitivity Reactions [see Warnings and Precautions (5.5) ] • Severe and Disabling Arthralgia [see Warnings and Precautions (5.6) ] • Bullous Pemphigoid [see Warnings and Precautions (5.7) ] Adverse reactions reported in ≥5% of patients treated with JANUVIA and more commonly than in patients treated with placebo are: upper respiratory tract infection, nasopharyngitis and headache.
Interactions
7 DRUG INTERACTIONS 7.1 Insulin Secretagogues or Insulin Coadministration of JANUVIA with an insulin secretagogue (e.g., sulfonylurea) or insulin may require lower doses of the insulin secretagogue or insulin to reduce the risk of hypoglycemia. [See Warnings and Precautions (5.4) .]
Warnings
5 WARNINGS AND PRECAUTIONS • Pancreatitis: There have been postmarketing reports of acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis. If pancreatitis is suspected, promptly discontinue JANUVIA. ( 5.1 ) • Heart failure : Heart failure has been observed with two other members of the DPP-4 inhibitor class. Consider risks and benefits of JANUVIA in patients who have known risk factors for heart failure. Monitor patients for signs and symptoms. ( 5.2 ) • Acute Renal Failure: Has been reported postmarketing, sometimes requiring dialysis. Assessment of renal function is recommended prior to initiating JANUVIA and periodically thereafter. 4 CONTRAINDICATIONS History of a serious hypersensitivity reaction to sitagliptin, such as anaphylaxis or angioedema. [See Warnings and Precautions (5.5) ; Adverse Reactions (6.2) .] History of a serious hypersensitivity reaction to sitagliptin, such as anaphylaxis or angioedema ( 5.5 , 6.2 )
Pregnancy
8.1 Pregnancy Risk Summary The limited available data with JANUVIA in pregnant women are not sufficient to inform a drug-associated risk for major birth defects and miscarriage. There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations ]. No adverse developmental effects were observed when sitagliptin was administered to pregnant rats and rabbits during organogenesis at oral doses up to 30-times and 20-times, respectively, the 100 mg clinical dose, based on AUC [see Data ] .
Storage
Storage Store at 20-25°C (68-77°F), excursions permitted to 15-30°C (59-86°F). [See USP Controlled Room Temperature.]
