Capsaicin dosing frequency for 0.025%-0.15% preparations is

• A. 3-4 times daily
• B. Once daily
• C. Twice daily
• D. Hourly

Answer: (A)

Capsaicin works by gradually desensitizing and depleting substance P from peripheral nerve endings in the skin. With low-concentration topical formulations (0.025% to 0.15%), the desensitization effect builds up with repeated exposure, so maintaining a steady level of drug on the skin is necessary to stay therapeutic. That’s why these preparations are typically used several times a day—about three to four applications—to sustain analgesia and achieve meaningful relief. Using it only once or twice daily wouldn’t keep the affected skin repeatedly exposed long enough to produce lasting desensitization, while hourly application isn’t practical and increases irritation without added benefit. Expect some initial burning with first uses, which often diminishes with continued treatment.
