What is menthol topical?
Menthol is either manmade or made from the extracts of mint oil. Menthol provides a cooling sensation when applied to the skin or other tissues (such as the tongue, gums, or inside the cheeks).
Flanax Cough (for use inside the mouth) is used to treat minor sore throat pain, or mouth irritation caused by a canker sore.
Menthol topical may also be used for purposes not listed in this medication guide.
