Recommendations for Use in Renal Impairment
- • Assess renal function prior to initiation of GLUMETZA and periodically thereafter.
- • GLUMETZA is contraindicated in patients with an estimated glomerular filtration rate (eGFR) below
- 30 mL/minute/1.73 m2.
- • Initiation of GLUMETZA in patients with an eGFR between 30 to 45 mL/minute/1.73 m2 is not recommended.
- • In patients taking GLUMETZA whose eGFR later falls below 45 mL/minute/1.73 m2, assess the benefit risk of
- continuing therapy.
- • Discontinue GLUMETZA if the patient’s eGFR later falls below 30 mL/minute/1.73 m2 [see Contraindications (4) and Warnings and Precautions (5.1)].
Discontinuation for Iodinated Contrast Imaging Procedures
Discontinue GLUMETZA at the time of, or prior to, an iodinated contrast imaging procedure in patients with an eGFR between 30 and 60 mL/minute/1.73 m2; in patients with a history of liver disease, alcoholism or heart failure; or in patients who will be administered intra-arterial iodinated contrast. Re-evaluate eGFR 48 hours after the imaging procedure; restart GLUMETZA if renal function is stable [see Warnings and Precautions (5.1)].
