Histafree Eye Drops contain Olopatadine 0.1% w/v, a selective histamine H1-receptor antagonist with mast cell stabilizing properties, indicated for the relief of symptoms associated with allergic conjunctivitis. Olopatadine acts by inhibiting the release of histamine and other inflammatory mediators from mast cells, thereby reducing ocular itching, redness, and swelling. This formulation provides rapid and sustained relief from allergic eye symptoms such as itching, burning, watering, and redness caused by exposure to allergens including pollen, dust, and pet dander. Histafree Eye Drops are intended for topical ophthalmic use and are suitable for adults and children over the age of three. The drops are preservative-free, minimizing the risk of ocular irritation and hypersensitivity reactions. Administration involves instilling one drop into the affected eye(s) twice daily or as directed by a healthcare professional. Caution is advised in patients with hypersensitivity to Olopatadine or any component of the formulation. Contact lens wearers should remove lenses prior to application and wait at least 15 minutes before reinsertion. Histafree Eye Drops offer an effective, well-tolerated option for managing allergic conjunctivitis, improving patient comfort and quality of life.
