Skin Problems Spotlight
Pruritus results from a tingling, irritating or uneasy sensation on the skin. Skin irritation and inflammation from a rash is a common cause of pruritus. Other common causes include chemical irritants, such as soap and laundry detergent; dry skin; and medication side effects. Insect stings and bites may also result in pruritus. Depending on the cause, itching may occur in one localized area or the entire body, and it may be accompanied by redness, pain, swelling, or discharge from associated lesions or pustules.
Allergic reactions can lead to itching of the skin and, sometimes, of the entire face or body. In rare cases, pruritus of the nipples is a symptom of breast cancer. Medications, including antibiotics (sulfonamides, penicillin), opiates (morphine and its derivatives), phenothiazines like chlorpromazine (Thorazine) and prochlorperazine (Compazine), or isoniazid, can all lead to pruritus. Vitamin A supplementation may also cause pruritus.
Seek immediate medical care (call 911) if you experience pruritus along with sudden facial or throat swelling, difficulty breathing, a change in level of consciousness, or severe abdominal pain, as these may be a sign of anaphylaxis, a life-threatening allergic reaction.
If your pruritus is persistent or causes you concern, seek prompt medical care.
