Renal dose adjustment summary

High-level dosing considerations by eGFR with safety reminders.

Last reviewed January 5, 2026

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.

Dosing

60 and above

Dosing approach: Verify the drug-specific regimen
Key reminders: Kidney function alone does not establish dose safety.

45-59

Dosing approach: Caution with renally cleared meds
Key reminders: Consider lower starting doses and closer monitoring.

30-44

Dosing approach: Check medication-specific thresholds
Key reminders: Some medicines need reduction or avoidance; do not apply one adjustment to every medicine.

Below 30

Dosing approach: Review each drug and indication
Key reminders: Seek pharmacy/nephrology input; do not automatically stop all medicines at this threshold.

Dialysis

Dosing approach: Dialysis-specific dosing
Key reminders: Check timing around dialysis sessions.

Renal dose adjustment summary: dosing
eGFR (mL/min/1.73 m2)	Dosing approach	Key reminders
60 and above	Verify the drug-specific regimen	Kidney function alone does not establish dose safety.
45-59	Caution with renally cleared meds	Consider lower starting doses and closer monitoring.
30-44	Check medication-specific thresholds	Some medicines need reduction or avoidance; do not apply one adjustment to every medicine.
Below 30	Review each drug and indication	Seek pharmacy/nephrology input; do not automatically stop all medicines at this threshold.
Dialysis	Dialysis-specific dosing	Check timing around dialysis sessions.

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.
For DOACs, use Cockcroft-Gault creatinine clearance with the drug-specific dosing guide rather than substituting laboratory eGFR.
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.
