Topical Capsaicin

Reviewed by the Nimbera editorial team · Last updated May 2026

Simpson 2017 J Pain (PMID 27746370) - double-blind RCT in 369 patients found capsaicin 8% patch reduced average daily pain score by 27.4% vs 20.9% for placebo (P=0.025), with median time to response of 19 vs 72 days.$10-$25/month for OTC cream; prescription patch is applied in-clinic (cost varies by insurance)

How to use

Over-the-counter 0.025-0.1% capsaicin cream: apply a thin layer to the painful area 3-4 times daily, every day. Consistent daily use is essential - the effect builds over 2-4 weeks as substance P is depleted. Wear gloves when applying and wash hands thoroughly afterward. Keep away from eyes, mucous membranes, and broken skin. High-concentration 8% patches (Qutenza) are prescription-only and applied by a healthcare provider in a clinical setting.

How it works

Capsaicin binds to TRPV1 (transient receptor potential vanilloid 1) receptors on pain-sensing C-fibers, causing initial activation (burning sensation) followed by prolonged defunctionalization and depletion of substance P, the primary neuropeptide responsible for transmitting pain signals. Repeated application leads to desensitization of pain-conducting nerve fibers, reducing the perception of neuropathic pain without causing permanent nerve damage at low concentrations.

Where to buy

OTC creams (0.025-0.1% capsaicin) available at pharmacies under brands including Zostrix, Capzasin, and generics. High-dose 8% patches (Qutenza) require a prescription and clinical application. Look for products specifically labeled for nerve pain or neuropathy.

Typical cost: $10-$25/month for OTC cream; prescription patch is applied in-clinic (cost varies by insurance)

Safety notes

Initial burning, stinging, and redness at the application site are expected and normal - they typically diminish with continued use over 1-2 weeks. Do not apply to broken, irritated, or infected skin. Do not use near eyes or on the face without medical guidance. Do not apply heat (heating pads) to treated areas as this intensifies absorption and burning. Wash hands immediately after application - accidental eye contact causes intense pain.
