On 06-sep-2022, a spontaneous report from the united states was received via telephone regarding a 66-year-old female who used a thermacare neck/shoulder/wrist 8hr heat wrap.Medical history included high cholesterol.Allergies included sodium pentothal, sulfonamides, penicillin, and swordfish.Concomitant products included an unspecified medication for high cholesterol.On (b)(6) 2022, the consumer applied a thermacare neck/shoulder/wrist 8hr heat wrap directly to her skin on her left thigh.She wore loose fitting jogging pants over the heat wrap.Approximately 4 hours after application, the heat wrap started to fall off.The edges were peeled back and were no longer sticking to her skin.She was at a store and went to the bathroom to see if she could help make it stick.She removed her clothing and noted skin redness at the application site.She noted the heat wrap burned her in 3 different places.The redness was in the shape of the heat wrap and was only at the application site.She denied pain or discomfort.After she saw the redness, she did not feel comfortable in trying to get the heat wrap to stick.She threw the patch away and went home.Once she arrived at home, she applied ice to the area and aloe vera.She did not go to the hospital because she thought they would just tell her as of (b)(6) 2022, the redness was gradually fading and was pink in color.She did not have any pain, blisters, or open areas.
