Zaditen syrup is used to treat various allergic conditions such as rhinitis (inflammation of the mucous membranes in the nose) and conjunctivitis (inflammation of the mucous membranes in the eye).

It is also indicated for the prevention and treatment of allergic disorders such as hives, dermatitis, allergic rhinitis, and conjunctivitis.

Zaditen syrup contains the active ingredient ketotifen, which is an antihistamine with anti-allergy properties. It works by blocking the allergic response and reducing inflammation.
