One or two intact local summaries. No averaged regimen, patient-specific dose or automatic source preference.
1 local source card selected. Local card fingerprints checked where supplied. This is not an original-document hash, source-currency guarantee or clinical approval. Record-level cautions below are the current library's cautions, not a frozen prior version.
Independent clinical review is pending. Confirm indication, exact formulation/route, population, renal measure and units, kidney-function stability, dialysis prescription, interacting drugs, monitoring and source revision. An RX mirror and its original label are not independent corroboration. Missing disagreement notes do not certify agreement.
These historical serum-creatinine cutoffs are not a current-label validation. A separately attributed current U.S. eGFR-based label must control current product-label dosing.
The preserved source uses historical serum-creatinine cutoffs. The imported U.S. immediate-release label instead uses indexed eGFR, and contraindicates use below 30 mL/min/1.73 m2. The old rule and current-label summary must not be blended.
The joint ADA/KDIGO 2022 consensus supports selected CKD use with a lower daily dose at eGFR 30-44. The U.S. label separately discourages initiation between eGFR 30 and 45 and requires benefit-risk reassessment for continued therapy below 45.
What to reconcile: Do not interpret a continuation strategy as automatic authorization for a new start. Reconcile label, guideline, acute illness and monitoring; document the plan, including when therapy should be held or reassessed.
Open this note and its source referencesStart 500 mg twice daily or 850 mg daily with meals. Increase by 500 mg weekly or 850 mg every 2 weeks according to response and tolerance; the labeled maximum is 2550 mg/day in divided doses.

Use indexed eGFR (mL/min/1.73 m2): below 30, treatment is contraindicated; starting treatment at 30-45 is not recommended. Reassess continuation if eGFR falls below 45 and discontinue below 30. Check renal function before treatment and periodically. For iodinated contrast, hold at/before the procedure with eGFR 30-60, specified liver/alcohol/heart-failure risks, or intra-arterial contrast; reassess after 48 hours and restart only when stable.
