Indications
Menthol is used on the skin and by inhalation. It is found in balms, rubs, gels, lozenges and inhalants to ease a blocked nose from colds, mild muscle and joint aches, minor itching and a sore throat.
How It Works
Menthol acts on cold-sensing nerve endings in the skin and nose, giving a cooling feeling. This feeling distracts from pain and itching and makes breathing through the nose feel easier, although it does not actually clear the blockage.
Dosage and Administration
- Rubs, balms and gels: apply a thin layer to the affected area and rub in gently, usually up to 3 or 4 times a day.
- Inhalation: use the number of drops in hot water or on a tissue stated on the label.
- Lozenges: dissolve slowly in the mouth, as directed on the label.
Wash your hands after use. Do not apply to the eyes, inside the nose, on broken skin or under tight bandages.
Interactions
No important interactions with medicines taken by mouth are known. Do not use with heating pads or other heat-producing rubs on the same area, as this can burn the skin.
Contraindications
- Allergy to Menthol or any ingredient of the product.
- Broken, burned or inflamed skin.
- Babies and children under 2 years: do not apply to the face, nose or chest area near the nose, as it can affect breathing.
Side Effects
Usually mild: redness, stinging or a burning feeling on the skin, and occasionally an allergic rash.
Get urgent medical help if there is blistering or severe burning, swelling of the face or throat, breathing difficulty (especially in a young child), or if a product containing Menthol has been swallowed.
Pregnancy and Lactation
Normal use of skin products and lozenges is generally considered acceptable. Ask a doctor or pharmacist before regular use of strong products. When breastfeeding, do not apply to the breast or chest area where the baby may touch or breathe it in.
Precautions and Warnings
For external use or inhalation only, unless the product is a lozenge. Keep away from the eyes. Stop using it if irritation develops. See a doctor if pain lasts more than 7 days or a cold does not improve.
Overdose
Swallowing concentrated Menthol or menthol oil can be poisonous, causing stomach pain, vomiting, drowsiness, unsteadiness and, in children, fits. Get emergency medical help.
Therapeutic Class
