What Does Renal Impairment Mean on a Medicine Label?
Renal impairment · say it: REE-nul im-PAIR-mentAlso written: kidney impairment, impaired renal function, reduced kidney function, renal insufficiency
Short answer
Renal impairment means the kidneys are not working as well as usual, so they clear waste and some medicines from the blood more slowly.
What it means
Renal means to do with the kidneys. Renal impairment means kidney function is reduced. It can be mild, moderate or severe, and it can be long-term (as in chronic kidney disease) or come on suddenly.
Medicine labels have a 'renal impairment' section because many medicines leave the body through the kidneys. If the kidneys are slower, the medicine can build up. Labels may say the dose needs adjusting, that blood tests are needed, or that the medicine should be avoided when kidney function is very low. Doctors usually judge this from blood tests such as eGFR or creatinine.
It is close in meaning to chronic kidney disease, but renal impairment only describes reduced function, not its cause or how long it has lasted.
Where you may see it
- The 'Use in specific populations' or 'Dosage in renal impairment' section of prescribing information
- Patient leaflets: 'Tell your doctor if you have kidney problems'
- Pharmacy and hospital medication reviews
📄 How it looks on a report
Dose adjustment is recommended in patients with moderate or severe renal impairment.
🙅 What it does not mean
- Being in a 'renal impairment' group on a label does not mean you have kidney failure.
- It does not mean every medicine is unsuitable for you; many just need a dose check.
- A single slightly low kidney test does not always mean long-term kidney disease.
