Topical medications can be creams, gels, sprays, or even shampoos - anything that is applied to the skin. Some topicals penetrate the outer layer of skin, while others act on the skin's surface. Some analgesic (pain reducers) or anti-itch medications are topically applied, such as the hydrocortisone and lidocaine, contained in our Itch Stop Shampoo or the hydrocortisone contained in our Itch Stop Series of itch control products.
Lidocaine belongs to the family of medicines called local anesthetics. When lidocaine is applied to the skin, it produces pain (and itch) relief by blocking the signals at the nerve endings in the skin. Lidocaine topical products are used in combination with other itch reducers like hydrocortisone, to relieve the itch caused by bug bites, scrapes, and other mild skin conditions.
