Topical itch treatments, those used on the skin, include
cold applications, creams, and lotions.
Cold applications: Because cold and itch travel along the same
nerve fibers, the use of cold can "jam the circuits" and deaden itch. Methods of applying cold include the following:
Cool water, either by running tap water over the affected area or placing a cold clean washcloth on the skin
Cool showers
A cool bath; products that contain colloidal oatmeal are available over the counter as an itch relief bath
Ice packs, either the commercially available type or ice cubes in a plastic bag
Anti-itch creams and lotions: Look for over-the-counter (OTC) remedies with these ingredients:
Camphor
Menthol
Phenol
Pramoxine
Diphenhydramine
Benzocaine (or one of the other "caine" anesthetics)
You can apply these products over and over -- every few minutes if needed. These preparations help numb the nerve endings and stop you from a frenzy of scratching, which leaves the skin raw, sore, and even itchier.
Although hydrocortisone-containing creams and lotions are often promoted as itch reducers, this ingredient only helps an itch that is caused by a
rash responsive to cortisone, such as
eczema and
seborrhea. Since OTC hydrocortisone-containing creams and lotions are weak (even so-called "maximum-strength" products contain only 1%), they aren't too helpful for itch even in responsive conditions. When itching is caused by irritations of other sorts (
insect bites, for instance), hydrocortisone doesn't help much at all. If you use hydrocortisone for 10 days and experience no improvement, you should see a physician to help determine the cause of your itch.
