Pharmacological mechanism

Used for temporary relief of minor pain and itching associated with sunburn, insect bites, minor burns, cuts, scrapes, and skin irritations; also used in throat lozenges for sore throat relief

Works as a topical anesthetic by blocking sodium channels in nerve endings, preventing the transmission of pain and itch signals to the brain

For topical use only; avoid contact with eyes and mucous membranes (unless formulation is specifically designed for these areas); do not apply to large areas of broken or damaged skin; discontinue use if irritation or allergic reaction occurs; keep out of reach of children
