# Pain Management in CKD: Reduce Exposure, Preserve Function

Treat the pain mechanism while checking predictable kidney, bleeding, sedation, and fall risks.

## Define what limits function

Distinguish focal musculoskeletal pain, neuropathic pain, acute injury, and systemic illness. Set a measurable goal such as walking or sleep. Unexplained fever, weakness, trauma, or progressive neurologic signs changes the evaluation.

## Identify the NSAID risk combination

Systemic NSAIDs constrict the afferent arteriolar response. Dehydration, diuretics, and ACE inhibitor/ARB therapy increase susceptibility to AKI. Ask specifically about over-the-counter ibuprofen or naproxen.

## Use local options for a local problem

Exercise modification, rehabilitation, and selected topical treatments can reduce systemic drug exposure. A topical NSAID still needs labeled use and intact skin; topical lidocaine fits certain localized neuropathic syndromes, not every pain mechanism.

## Check accumulation and sedation

Gabapentin/pregabalin and several opioid metabolites require kidney-function-aware prescribing. New somnolence, confusion, myoclonus, or falls warrants medication review; do not simply increase the dose for persistent pain.

## A concrete follow-up check

After a pain-plan change, assess function, adverse effects, new edema, blood pressure, and any indicated kidney/electrolyte testing. Ask whether multiple combination products duplicate the same analgesic.

## Worked example

A patient on a diuretic and ARB develops diarrhea, then adds ibuprofen for back pain. Address volume loss and medication-related AKI risk with the treating clinician; substituting a generic “pain bundle” does not solve the interaction.
