Where it stands

Rapid Summary

Overview

Active component of chili peppers. Radically depletes Substance P from sensory nerve endings. Highly effective for localized neuropathic pain and osteoarthritis, but burns fiercely upon initial application.

Clinical Focus

The patient MUST wash their hands immediately after application to prevent catastrophic eye or mucosal burns.

Bottom Line

Capsaicin cream is a topical analgesic for neuropathic and musculoskeletal pain, but requires consistent application for 2-4 weeks before benefit and causes initial burning sensation.

Route / Formulation

Creams. High-potency clinical patches (used in pain clinics). (Zostrix (0.025%), Zostrix HP (0.075%), Qutenza (8% patch - Specialist only))

Usual Dose & Max

Topical Rub into affected area 3 to 4 times daily. Must be used consistently; PRN use is completely ineffective. Apply a thin layer QID.

Best Uses

Capsaicin cream is a topical analgesic for neuropathic and musculoskeletal pain, but requires consistent application for 2-4 weeks before benefit and causes initial burning sensation.

Key Risks

Dermatological: Severe localized burning, stinging, and erythema at the application site (especially during the first week). Mucosal: Excruciating pain if transferred to the eyes, nose, or genitals.

Key Interactions

NONE — Safe to use with all systemic medications.

Monitoring

Counsel patient: The burning sensation means it is working. It will fade after 3-5 days. If they stop using it because of the burn, the nerve resets and they have to start the painful process all over again.

Clinical Pearl

Advise the patient to apply the cream using a disposable nitrile glove. Washing hands with soap does not easily remove the lipophilic capsaicin oil, and rubbing their eye 2 hours later will still cause a severe burn.
