Zaylube Eye Drop contains Carboxymethylcellulose 0.5% w/v, a viscous ophthalmic lubricant designed to provide effective relief from dry, irritated, or strained eyes. Carboxymethylcellulose is a cellulose derivative that acts as a tear substitute, enhancing ocular surface moisture and promoting lubrication to alleviate discomfort associated with dryness caused by environmental factors, prolonged screen exposure, contact lens wear, or post-surgical conditions. The formulation mimics natural tears, reducing friction between the eyelid and the corneal surface, thereby minimizing irritation and preventing further damage to the ocular epithelium. Zaylube Eye Drop is preservative-free, reducing the risk of hypersensitivity or allergic reactions, making it suitable for frequent or long-term use. It is indicated for symptomatic relief of dry eye syndrome, keratoconjunctivitis sicca, and other conditions characterized by insufficient tear production or poor tear film quality. The recommended dosage is one to two drops in the affected eye(s) as needed, with caution advised to avoid contamination of the dropper tip. Patients should consult an ophthalmologist if symptoms persist or worsen. Zaylube Eye Drop is intended for topical ocular use only and should be stored at room temperature, protected from light and moisture.
