Severe itching all over the body, especially on the back, is commonly caused by allergy, dry skin, urticaria (hives), heat-related irritation, stress, insect bites, or skin conditions such as eczema. Less commonly, problems with the liver, kidneys, or thyroid may also cause repeated itching. If Incid-L Tablet (Cetirizine) is not helping, it may mean that the underlying trigger is not fully controlled or that the condition is not allergy-related. You should consult a doctor or dermatologist for proper evaluation rather than continuing the same tablet without benefit. The doctor may suggest blood tests to identify the cause or change your treatment to a stronger or different antihistamine, or add creams to soothe the skin. In the meantime, avoid hot showers, use a gentle moisturiser twice daily, wear loose cotton clothing, and try not to scratch, as this can worsen itching. Applying cool compresses can also give temporary relief.

Allergic reactions on the hands are often caused by contact with soaps, detergents, metals, plants or new skincare products. The skin may become red, itchy, dry, or slightly swollen. The first step is to avoid anything that may have triggered the reaction. You may take an over-the-counter antihistamine, such as cetirizine or loratadine, once daily to help reduce itching and allergy symptoms. A mild hydrocortisone cream can be applied gently to the affected areas once or twice a day for a short period. Use a simple, fragrance-free moisturiser several times a day to protect the skin barrier. Avoid scratching and wash your hands with lukewarm water and a gentle soap. Applying cold compresses can help reduce itching and swelling. If the rash is severe, painful, spreading, or shows no improvement within a few days, please see a doctor immediately for proper assessment and treatment.
