Common antipruritics
Topical antipruritics in the form of creams and sprays are often available over-the-counter. Oral anti-itch drugs also exist and are usually prescription drugs. The active ingredients usually belong to the following classes:
Antihistamines such as diphenhydramine (Benadryl)
Corticosteroids such as hydrocortisone topical cream, see topical steroid
Local anesthetics such as benzocaine topical cream (Lanacaine)
Counterirritants, such as mint oil, menthol, or camphor
Disputed and questionable antipruritics
Burow's solution (aluminium acetate)
Olive oil
Jewelweed, has been shown to be devoid of any anti-itch activity in several controlled studies
SSRIs (selective serotonin reuptake inhibitors) comprise a class of medicines commonly used for depression, and are also said to be effective in controlling pruritus in a small number of refractory cases. Mirtazapine, a different type of antidepressant, also has antipruritic effects due to its strong antagonism of the H1 receptor.
Calamine lotion, containing zinc oxide and iron(III) oxide, is a traditional remedy for mild itching, such as that typically associated with chicken pox - although the U.S. Food and Drug Administration (FDA) has asserted that it has little if any effect.
Home remedies
Paste of sodium bicarbonate (baking soda) and water, applied topically
Ammonium hydroxide (household ammonia), applied topically
Cooling with ice or cold water (usually stops the itch for as long as the ice or cold water is applied)[citation needed]
Heat application with a common hairdryer set on high heat counteracts the enzymes.
Slightly painful stimulation like rubbing, slapping or scratching, based on a spinal antagonism between pain- and itch-processing neurons[citation needed]
