Itch facts

  • The medical term for itching is pruritus.
  • Infections, bites and stings, infestations, chronic diseases, sun exposure, and dry skin are among the numerous causes of itching.
  • Anti-itch creams and lotions containing camphor, menthol, phenol, pramoxine (Caladryl, Tronolane), diphenhydramine (Benadryl), or benzocaine can bring relief.
  • Some cases of itching will respond to corticosteroid medications.
  • It is best to avoid scratching when possible to avoid worsening of the condition and disruption of the skin that could lead to bacterial infection.
  • If itching persists with time or worsens, or is associated with skin lesions, consulting a health care professional is advisable.

What is an itch?

Itch is an irritation in the skin that elicits an urge to scratch. Itches are a problem that everyone experiences and can be localized (limited to one area of the body) or generalized (occurring all over the body or in several different areas). Sometimes, itching may be worse at night. In medical terminology, itching is known as pruritus.

Generalized itch is often more difficult to treat than localized itch. Itches can also occur with or without skin lesions (bumps, blisters, rash, or abnormalities that can be seen on the skin). An itch that is accompanied by a visible skin abnormality usually should be evaluated by a physician and, in some cases, by a dermatologist since the problem is likely to be a condition that requires specialized medical treatment (for example, eczema, scabies, etc.).
