Contraindications
- Avoid standard dosing assumptions when eGFR is below medication-specific safety thresholds.
- Avoid nephrotoxic combinations during acute kidney injury risk periods when alternatives exist.
- Avoid finalizing high-risk regimens without drug-specific reference confirmation.
Renal and hepatic considerations
- This is a high-level summary; always verify with product monographs or RxTx.
- Adjust for acute kidney injury and rapid changes in creatinine.
- Integrate hepatic function review for medications with mixed renal/hepatic clearance.
Pregnancy and lactation cautions
- Pregnancy changes renal physiology and can alter drug exposure; use pregnancy-specific references.
- During lactation, confirm medication transfer risk and infant safety context.
- Seek specialist or pharmacist support when maternal-fetal risk is uncertain.
Monitoring checkpoints
- Recheck renal labs after clinically meaningful medication changes or acute illness.
- Coordinate with pharmacy for complex polypharmacy.
- Document dose rationale and planned follow-up interval in the chart.
Stop or escalate criteria
- Hold or stop medications when rapid creatinine rise, severe electrolyte disturbance, or toxicity appears.
- Escalate when eGFR is below 30 mL/min/1.73 m2, dialysis is involved, or dosing references conflict.
- Escalate urgently if clinical instability develops while dosing uncertainty remains unresolved.
