Si2norm Dosage/Direction for Use

The recommended dose of Sitagliptin is 100 mg once daily as monotherapy or as combination therapy with metformin, a sulfonylurea, insulin (with or without metformin), a PPARγ agonist (e.g., thiazolidinediones), metformin plus a sulfonylurea, or metformin plus a PPARγ agonist.
When Sitagliptin is used in combination with a sulfonylurea or with insulin, a lower dose of sulfonylurea or insulin may be considered to reduce the risk of sulfonylurea- or insulin-induced hypoglycemia.
Patients with Renal Impairment: Because there is a dosage adjustment based upon renal function, assessment of renal function is recommended prior to initiation of Sitagliptin and periodically thereafter.
For patients with mild renal impairment (estimated glomerular filtration rate [eGFR] ≥60 mL/min/1.73 m² to <90 mL/min/1.73 m²), no dose adjustment for Sitagliptin is required.
For patients with moderate renal impairment (eGFR >45 mL/min/1.73 m² to 60 mL/min/1.73 m²), no dosage adjustment for Sitagliptin is required.
For patients with moderate renal impairment (eGFR ≥30 mL/min/1.73 m² to <45 mL/min/1.73 m²), the dose of Sitagliptin is 50 mg once daily.
For patients with severe renal impairment (eGFR ≥15 mL/min/1.73 m² to <30 mL/min/1.73 m²) or with end-stage renal disease (ESRD) (eGFR <15 mL/min/1.73 m²), including those requiring hemodialysis or peritoneal dialysis, the dose of Sitagliptin is 25 mg once daily. Sitagliptin may be administered without regard to the timing of dialysis.
Method of Administration: Sitagliptin can be taken orally with or without food.
