What is the typical concentration range found in over-the-counter topical creams using capsaicin for pain management?
Answer
0.025% to 0.1% capsaicin
For localized pain relief applications such as creams or patches, the effective concentration of capsaicin is carefully managed, usually falling within a narrow range suitable for over-the-counter products. This range is specified as being between 0.025% and 0.1% capsaicin. This contrasts sharply with the amounts found in culinary cayenne powder, underscoring the necessity of understanding concentration when using the compound therapeutically versus just for flavoring food, especially concerning safety and efficacy.
