Croma Eye Drops are formulated to treat allergic conjunctivitis by combining two active ingredients: Sodium Cromoglicate (40 mg) and Tetrahydrozoline Hydrochloride (0.5 mg). Sodium Cromoglicate acts as a mast cell stabilizer, preventing the release of histamine and other inflammatory mediators responsible for allergic reactions. Tetrahydrozoline Hydrochloride is a decongestant that provides rapid relief from redness and swelling by constricting blood vessels in the eye. This combination ensures both immediate and long-term relief from symptoms such as itching, redness, and watering of the eyes. Regular use as directed can effectively manage eye allergy symptoms and improve comfort. .
