Xigduo XR Dosage/Direction for Use

Dapagliflozin/metformin HCl extended-release tablets: XIGDUO XR should be taken orally, once daily with the evening meal. The recommended dose of dapagliflozin is 10 mg once daily. The recommended starting dose of metformin is 500 mg once daily, which can be titrated to 2000 mg once daily, with gradual dose escalation to reduce the gastrointestinal side effects due to metformin. The maximum dose of XIGDUO XR is dapagliflozin 10 mg/metformin extended-release 2000 mg taken as two 5 mg/1000 mg tablets once daily.
In patients treated with metformin, the dose of XIGDUO XR should provide metformin at the dose already being taken, or the nearest therapeutically appropriate dose.
If no adequate strength of XIGDUO XR is available, individual mono-components should be used instead of the fixed dose combination.
Patients should be informed that XIGDUO XR tablets must be swallowed whole and never crushed, cut, or chewed. Occasionally, the inactive ingredients of XIGDUO XR will be eliminated in the feces as a soft, hydrated mass that may resemble the original tablet.
Special populations: Patients with renal impairment: Assess renal function prior to initiation of XIGDUO XR and periodically thereafter (see Precautions and Pharmacology: Pharmacokinetics under Actions).
Mild renal impairment: No dose adjustment of XIGDUO XR is required for patients with mild renal impairment (eGFR 60-89 mL/min/1.73 m² by Modified Diet in Renal Disease [MDRD] eGFR equation).
Moderate renal impairment: XIGDUO XR is not recommended for the treatment of diabetes in patients with eGFR persistently below 45 mL/min/1.73 m2 (see Precautions). No dose adjustment is required for patients with eGFR ≥ 45 mL/min/1.73 m²).
Severe renal impairment: Due to the metformin component, XIGDUO XR is contraindicated in patients with severe renal impairment (eGFR < 30 mL/min/1.73 m²) (see Contraindications).
Patients with hepatic impairment: Since impaired hepatic function has been associated with some cases of lactic acidosis in patients taking metformin, XIGDUO XR should generally be avoided in patients with clinical or laboratory evidence of hepatic impairment (see Precautions).
Pediatric and adolescent patients: Safety and effectiveness of XIGDUO XR in pediatric and adolescent patients have not been established.
Elderly patients: Because metformin is eliminated by the kidney, and because elderly patients are more likely to have decreased renal function, XIGDUO XR should be used with caution as age increases. The renal function recommendations provided for all patients also apply to elderly patients.
Patients at risk for volume depletion: For patients at risk for volume depletion due to co-existing conditions, a 5 mg starting dose of dapagliflozin may be appropriate.
