From the Guidelines

The Signal Relief Patch does not contain any medication or active pharmaceutical ingredients, specifically capsaicin, as it is marketed as a non-drug, non-transdermal patch that uses nanotechnology to allegedly capture and redirect electromagnetic signals from pain receptors in the body. The patch consists of a polymer substrate embedded with microscopic antennas that supposedly interact with the body's electrical signals. However, there is no substantial scientific evidence supporting these claims or the effectiveness of the technology, as seen in studies such as 1, which focuses on pharmacologic therapies for treatment of pain in diabetes, including capsaicin, but does not mention the Signal Relief Patch. Some key points to consider include:

  • The patch works through a self-adhesive backing that allows it to be placed directly on the skin near the area of pain.
  • Users should be aware that despite marketing claims, the Signal Relief Patch has not been FDA-approved for pain treatment, and its mechanism of action remains scientifically unproven, unlike capsaicin, which has received FDA approval for treatment of pain in DPN using an 8% patch, as mentioned in 1.
  • If experiencing pain, it would be more advisable to consult with a healthcare provider about evidence-based pain management strategies rather than relying solely on products with unsubstantiated claims, such as the Signal Relief Patch. The provided evidence, including studies 1, 1, and 1, discusses the use of capsaicin for pain management, but does not support the use of the Signal Relief Patch. Therefore, it is recommended to prioritize evidence-based treatments, such as capsaicin, which has been shown to be effective in reducing pain, as seen in studies such as 1.
