Azatadine is primarily used as an antihistamine to manage symptoms associated with allergic conditions. It effectively alleviates symptoms like sneezing, runny nose, itching, and watery eyes caused by allergic rhinitis or hay fever. Additionally, it is used to treat skin reactions such as hives and itching due to its anti-allergic properties. Azatadine works by blocking the action of histamine, a substance in the body that triggers allergic responses. It is also sometimes combined with other medications, such as decongestants, to provide broader relief from allergy symptoms. Its sedative effects may also help in managing mild anxiety or promoting sleep in certain cases.
