Lubirest Eye Drop contains Carboxymethylcellulose 0.5% w/v, a viscous ophthalmic lubricant designed to provide effective relief from dry eye symptoms. Carboxymethylcellulose acts as a tear substitute, enhancing ocular surface hydration by stabilizing the tear film and preventing moisture evaporation. This formulation is indicated for the temporary relief of burning, irritation, and discomfort caused by dryness of the eye or exposure to wind and sun. Lubirest Eye Drop is suitable for patients experiencing mild to moderate dry eye syndrome, including those with environmental or contact lens-related dryness. The preservative-free formulation minimizes the risk of ocular irritation and hypersensitivity reactions, making it appropriate for frequent use. Administration involves instilling one or two drops into the affected eye(s) as needed, ensuring proper hygiene to avoid contamination. Clinical studies have demonstrated that Carboxymethylcellulose effectively improves tear film stability and reduces ocular surface damage, contributing to enhanced patient comfort and visual performance. Lubirest Eye Drop is contraindicated in patients with known hypersensitivity to any component of the formulation. Patients should consult an eye care professional if symptoms persist or worsen after prolonged use. This product is intended for topical ophthalmic use only and should be stored at controlled room temperature, protected from light.
