Federal regulators are warning certain over-the-counter products applied to the skin for the relief of mild muscle and joint pain have been reported to cause serious burns and skin injuries in some cases.
Food and Drug Administration officials noted such products contain menthol, methyl salicylate, or capsaicin, and are marketed under various brand names, such as Bengay, Capzasin, Flexall, Icy Hot, and Mentholatum.
When they’re applied to the skin, they produce a local sensation of warmth or coolness. But in rare cases, FDA regulators said they can cause first- to third-degree chemical burns — some which have required hospitalization.
Since 1969, the FDA said there have been 43 cases of burns caused by the products, usually within the first 24 hours after use.
The FDA recommends:
• Do not apply OTC topical muscle and joint pain relievers to wounds or damaged, broken, or irritated skin. Also do not allow contact with eyes and mucous membranes (such as the skin inside your nose, mouth, or genitals).
• Consumers who experience pain, swelling, or blistering of the skin after using the products — including creams, lotions, ointments, and patches — should seek medical attention immediately.
• Healthcare professionals should counsel patients about how to use the products safely and inform them about the risk of serious burns. When applying OTC topical muscle and joint pain relievers to the skin, do not bandage the area tightly and do not apply local heat (heating pads, lamps, hot water in bags or bottles) because doing so can increase the risk of serious burns.
