By doing so, they help alleviate symptoms associated with seasonal allergies such as hay fever, sneezing, runny nose, and itchy eyes. These tablets also provide relief from nasal congestion, a common symptom of the common cold, by reducing blockage and swelling in the nasal passages. The effects of Clarinase tablets are long-lasting, allowing you to go about your day without being bothered by allergy or cold symptoms
