Epilube 1% Eye Drop contains Carboxymethylcellulose 1% w/v, a viscoelastic polymer used as a lubricant and artificial tear substitute for the relief of dry, irritated eyes. It is indicated for the management of symptoms associated with dry eye syndrome, including burning, stinging, irritation, and discomfort caused by reduced tear production or environmental factors. The formulation enhances tear film stability by increasing ocular surface hydration and providing a protective coating that reduces friction between the eyelid and cornea during blinking. Epilube 1% Eye Drop is preservative-free, minimizing the risk of ocular surface toxicity and making it suitable for frequent use and for patients with sensitive eyes or those requiring long-term therapy. It is administered topically, typically instilled as one or two drops in the affected eye(s) as needed, with dosage adjusted according to symptom severity. The product is contraindicated in patients with known hypersensitivity to Carboxymethylcellulose or any other component of the formulation. Adverse effects are rare but may include transient blurred vision or mild ocular irritation upon instillation. Epilube 1% Eye Drop should be used under medical supervision, especially in patients with pre-existing ocular conditions or contact lens wearers.
