Menthol: Brands, Price & Uses in Bangladesh

Menthol is a topical counter-irritant and cooling agent used in a variety ofover-the-counter external preparations. Its indications, classified by strength of evidence, are:

Established / OTC-monograph approved uses

• Temporary relief of minor muscle aches, joint pain, sprains, and strains: appliedtopically as a cream, gel, ointment, lotion, or patch (often combined with other counter-irritantssuch as methyl salicylate or camphor).
• Temporary relief of minor itching (pruritus): including insect bites and minorskin irritation, in topical anti-itch preparations.
• Temporary relief of cold/cough symptoms: as an inhalant, chest rub, or lozengeingredient, Menthol produces a cooling sensation in the nose and throat that gives a subjective feelingof easier breathing and helps suppress minor cough irritation; it does not treat the underlyinginfection.
• Oral care / throat preparations: as a flavoring and mild local anesthetic inlozenges, mouthwashes, and oral sprays for temporary relief of minor mouth or throat irritation.

Adjunct / combination use

Menthol is frequently formulated together with other agents (e.g., camphor, methyl salicylate,eucalyptus oil, benzocaine) for combined counter-irritant, anesthetic, or decongestant-sensationeffects; in such products Menthol is one contributing ingredient rather than the sole active agent.

Not established / off-label

Menthol is not an antibiotic, does not treat infection or inflammation at its source, and is notestablished as effective for deep or chronic pain, nerve pain, or as a substitute for prescribedrespiratory therapy. Use for any purpose beyond temporary symptomatic relief should be discussed witha physician.

Adult and Pediatric Dosage (by formulation)

Administration

For external/topical use only unless the product is specifically labeled for oral use (e.g.,lozenges). Wash hands after topical application (unless the hands are the treated area). Do notbandage tightly, apply heat (such as a heating pad) over, or use with a heating device on an areatreated with Menthol, as this can increase absorption and cause burns. Avoid contact with the eyes,inner nose, mouth (for topical products), and broken or irritated skin. If symptoms persist beyond7 days, worsen, or are accompanied by fever, a physician should be consulted.

When used as directed, Menthol is generally well tolerated. Reported side effectsinclude:

• Local burning, stinging, or tingling sensation at the application site (common, usually mild andtransient)
• Skin redness (erythema) or irritation
• Contact dermatitis or allergic skin reaction (uncommon)
• Cold or "icy-hot" sensation more intense than expected, especially with excessive application
• Rarely, chemical burns if used with heat sources or under occlusive dressings
• With concentrated inhalant/rub products used near an infant's or young child's face: throattightness, breathing difficulty, or laryngospasm (rare but serious — see Contraindications andPrecautions)

Stop use and consult a physician if excessive irritation, blistering, or an allergic reactionoccurs.
