PREGNANCY AND BREASTFEEDING SAFETY: There are no adequate studies done on menthol and methylsalicylate to determine safe and effective use in pregnant women.

It is not known whether menthol and methylsalicylate enters breast milk; therefore, it is best to be cautious before using it in nursing mothers.

STORAGE: Menthol/methylsalicylate creams and patch are stored between 20 C to 25 C (68 F to 77 F). Balms are stored between 15 C to 30 C (59F to 86 F). Sprays, sticks, and foams should be stored away from heat and direct sunlight.

PREPARATIONS: Menthol/methylsalicylate topical products are available in cream, balm, spray, stick, patch, and foam.

DRUG INTERACTIONS: Menthol/methylsalicylate topical products should be used with caution with blood thinning medications like warfarin (Coumadin), nonsteroidal anti-Inflammatory drugs (NSAIDs), and steroids due to increased likelihood of bruising and bleeding resulting from methylsalicylate which acts like aspirin and can affect blood clotting.

DOSING:

Adults and children 12 years of age and older (Cream, balm, spray, stick, spray, balm, and foam): Apply liberally to affected area up to 3 to 4 times daily. Do not use on open wound or damaged skin. Do not use with a heating pad.

Children under 12 years of age: Consult a doctor.

For those 18 years and over, one patch should be placed on the affected area for 8 to 12 hours. A second patch may be added after removing the first one if pain continues. Do not use for more than 2 patches a day or for more than 3 days in a row.

DRUG CLASS AND MECHANISM: Menthol/methylsalicylate is used as a

topical analgesic. It works by first cooling the skin then warming it up, providing a topical anesthetic and analgesic action on the affected area. The cooling and warning action may interfere with transmission of pain signals through nerves.
