What Is Icy Hot and How Does It Work?

Icy Hot is a topical pain reliever that is used for minor arthritis pain, aching joints, and sore muscles. Icy Hot is available in several different formulations, but the brand name is best known for being the best-selling over-the-counter medicated back patch, according to the manufacturer.

The active ingredients in Icy Hot formulations are menthol or a combination of menthol and methyl salicylate. Some formulations also contain camphor. The ingredients cause a cooling sensation followed by a warming sensation that distracts you from the pain by blocking pain signals sent to the brain. The cooling sensation dulls the pain while the warming sensation relaxes it away.

All formulations are for external use only. There are over a dozen formulations of Icy Hot and different ways of applying it to the skin and to the part of the body where you want pain relief. These include patches, cream, gel spray, stick, and sleeve applications.

You need to read the ingredients on the label before you buy as they are different for similar-sounding Icy Hot products. The warnings on the label of all of the formulations of Icy Hot state the following:

• Use only as directed.
• Avoid contact with eyes or mucous membranes.
• Do not apply to wounds or irritated, broken, or damaged skin.
• Do not bandage tightly or use with a heating pad.
• If you are prone to allergy from aspirin or salicylates, consult a doctor before using the formulations that contain methyl salicylate.

Icy Hot continues to innovate its delivery systems. The formulations listed below are likely to change over time, with new ones added, old ones renamed, and less-popular forms discontinued. All formulations are for external use only.

Be sure to read each product before you buy it as there can be different ingredients included for similar-sounding and appearing products. Some have only menthol; others also have salicylates (aspirin) and some have camphor or lidocaine.
