Rub A535 Dual Action Back Patch is a pain relief product that comes in a patch form, indicated to provide both cold and hot therapy for targeted, effective relief of back pain and lower back pain. The medicated patch is formulated to start out cold to ease the pain and then turns too hot for soothing, penetrating relief. It is a flexible and greaseless patch that can provide up to 8 hours of targeted pain relief.
The patch contains multiple active ingredients, including menthol, methyl salicylate, and camphor, which work together to provide effective pain relief. It works by providing cooling and heating sensations to the affected back area. The patch starts out cold, which helps to relieve pain and reduce inflammation. After a while, the patch begins to warm up, which helps relax tense muscles and soothe the area.
