Even when Cetiriz provides momentary relief, symptoms may recur because colds frequently endure for several days. Maintain supportive care, which includes relaxation, steam inhalation, warm liquids, and avoiding dust and chilly air. See a physician if symptoms intensify, last longer than a week, or involve fever or breathing difficulties.

For allergy-related rashes, use cold compresses, antihistamines, and gentle moisturizers, and avoid the trigger if known. If the rash worsens, spreads, or persists, a doctor may prescribe topical steroids or anti-allergy medication.

Itching with small rashes can be due to allergies, dry skin, heat rash, insect bites, or mild infections like fungal dermatitis. If the rash spreads, lasts more than a few days, or comes with fever, a doctor should check it for proper diagnosis.
