Some topical pain relievers containing menthol may cause burns: Health Canada
TORONTO — Health Canada says a safety review has found a risk of serious burns with the use of some over-the-counter topical pain relievers that contain menthol.
These pain relievers are applied to the skin and are intended to help relieve muscle and joint pain. They come in a variety of formulations, including creams, gels, liquids and patches.
Health Canada has received 21 reports of serious side-effects involving topical pain relievers containing menthol in various concentrations, either as a single ingredient or in combination with other compounds.
In many cases, the products were used as directed, with burns, severe swelling and blistering appearing within 24 to 48 hours after the first application.
