Long-acting insulin analogue
Insulin Glargine with kidney impairment: dosing and safety
Kidney function affects how the body clears Insulin Glargine (Insulin Glargine) and many of its metabolites. For people with chronic kidney disease, dialysis, or even mild renal impairment from age or comorbidities, the standard 100 IU/mL dose may need adjustment. This page summarises the practical principles for Insulin Glargine in renal impairment.
Why renal function matters for Insulin Glargine
A meaningful fraction of Insulin Glargine or its active metabolites is cleared by the kidneys for many medications. Reduced eGFR slows clearance, raises plasma concentrations and prolongs effect. Insulin glargine binds the insulin receptor with similar affinity to human insulin, activating intracellular signalling that increases glucose uptake in muscle and adipose tissue, suppresses hepatic g… The prescribing information for Insulin Glargine usually specifies dose adjustments by eGFR threshold (e.g. 30–60 vs <30 mL/min/1.73m²).
Practical guidance
According to the prescribing information, baseline kidney function should be checked before starting Insulin Glargine and periodically during treatment. People on dialysis need specialist input on dose timing relative to dialysis. Acute kidney injury — from dehydration, infection or other medications — can shift Insulin Glargine effects unpredictably and may warrant a temporary hold at 100 IU/mL.
Frequently asked questions
Is Insulin Glargine safe with kidney problems? ▾
Mild to moderate kidney impairment usually allows Insulin Glargine at adjusted lower 100 IU/mL doses with monitoring. Severe impairment (eGFR <30) often requires substantial reduction or alternative therapy. The prescriber decides based on lab results and the indication.
Do I need lab tests on Insulin Glargine if I have kidney disease? ▾
Yes — periodic eGFR and electrolyte monitoring is the standard practice for Insulin Glargine in chronic kidney disease. Frequency depends on the severity of impairment and on Insulin Glargine-specific risks. The prescriber sets the schedule.
