Scope of this summary
Adults already diagnosed with painful diabetic polyneuropathy who are considering treatment for neuropathic pain. The AAN practice-guideline update is specific to this condition. It does not establish how to diagnose polyneuropathy, investigate its cause, manage the diabetic foot or treat postherpetic neuralgia, radiculopathy, trigeminal neuralgia, central pain or another neuropathic-pain syndrome.

The Bottom Line
- Discuss realistic goals before treatment: the AAN source frames success as reducing pain rather than guaranteeing complete elimination of symptoms.
- The guideline supports offering treatment from an effective medication class, including tricyclic antidepressants, SNRIs, gabapentinoids or sodium-channel blockers.
- Selection should account for adverse-effect profiles, relevant comorbidities, patient preferences and cost rather than assuming equal suitability for every person.
- When the initial class does not produce meaningful improvement or causes important adverse effects, offer a trial from a different effective class instead of another medicine from the same class.
- The AAN guideline states that opioids should not be used for painful diabetic polyneuropathy and also addresses topical and nonpharmacologic options.

Practical clinical workflow
1
Confirm that painful diabetic polyneuropathy has been established through a separate diagnostic process before applying this treatment-only summary.
2
Agree on the pain outcome that would count as meaningful improvement and identify adverse effects, comorbidities, preferences and affordability factors relevant to class selection.
3
Select one AAN-supported oral class or consider a source-supported topical or nonpharmacologic option without inferring a universal first-choice medicine from this summary.
4
Reassess whether treatment produced meaningful pain improvement and whether adverse effects are acceptable; the guideline does not support indefinite continuation without benefit.
5
If a change is needed, move to a different effective class and use current FDA labeling for product-specific contraindications, interactions, dose adjustment and monitoring.

Safety boundaries and escalation
- This treatment guideline does not substantiate a neuropathy diagnostic examination, laboratory panel, imaging strategy, electrodiagnostic threshold or etiologic work-up.
- It does not substantiate diabetic-foot surveillance, ulcer or ischemia management, fall assessment, emergency neurologic triage or diabetes-control targets.
- Class-level recommendations do not replace product labeling; dosing, renal or hepatic adjustment, interactions, pregnancy considerations and monitoring remain medicine-specific.
- Do not generalize these recommendations to another painful neuropathy, and do not use an opioid as treatment for painful diabetic polyneuropathy under this AAN guidance.

Localization
The AAN document is a US specialty-society treatment guideline, published in 2021 and reaffirmed in 2025. Its scope is painful diabetic polyneuropathy rather than all adult neuropathic pain. US formularies and coverage vary, and product-specific decisions must use current FDA labeling.
