1. What Neoclarityn oral solution is and what it is used for What Neoclarityn is

Neoclarityn contains desloratadine which is an antihistamine.

How Neoclarityn works

Neoclarityn oral solution is an antiallergy medicine that does not make you drowsy. It helps control your allergic reaction and its symptoms.

When Neoclarityn should be used

Neoclarityn oral solution relieves symptoms associated with allergic rhinitis (inflammation of the nasal passages caused by an allergy, for example, hay fever or allergy to dust mites) in adults, adolescents and children 1 year of age and older. These symptoms include sneezing, runny or itchy nose, itchy palate, and itchy, red or watery eyes.

Neoclarityn oral solution is also used to relieve the symptoms associated with urticaria (a skin condition caused by an allergy). These symptoms include itching and hives.

Relief of these symptoms lasts a full day and helps you to resume your normal daily activities and sleep.
