Recommendations for Use in Renal Impairment
- •
- Assess renal function prior to initiation of RIOMET and periodically thereafter.
- •
- RIOMET is contraindicated in patients with an estimated glomerular filtration rate (eGFR) below 30 mL/minute/1.73 m2.
- •
- Initiation of RIOMET in patients with an eGFR between 30 to 45 mL/minute/1.73 m2 is not recommended.
- •
- In patients taking RIOMET whose eGFR later falls below 45 mL/min/1.73 m2, assess the benefit risk of continuing therapy.
- •
- Discontinue RIOMET if the patient’s eGFR later falls below 30 mL/minute/1.73 m2 [see Warnings and Precautions (5.1)].
Discontinuation for Iodinated Contrast Imaging Procedures
- •
- Discontinue RIOMET at the time of, or prior to, an iodinated contrast imaging procedure in patients with an eGFR between 30 and 60 mL/min/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 RIOMET if renal function is stable.
