Chronic itching: Many times there is not a specific cause, like a food allergy, that we can find for itching, and we have to try different antihistamines in different doses to get relief. Zyrtec 10 and Allegra 180 usually work better than Claritin (loratadine) for itch, and it is safe to use at least 1 twice a day. Itching can be a symptom of a more serious medical condition, so see a doctor for tests if you haven't yet.
