About CARBOXYMETHYLCELLULOSE(1%W/V)
Introduction
Carboxymethylcellulose 1% w/v is an ophthalmic solution commonly used as artificial tears. It is a lubricating eye drop that helps relieve dryness and irritation of the eyes. This formulation contains carboxymethylcellulose sodium, a cellulose derivative that acts as a lubricant and moisturizer for the eye surface.
Uses
Used to relieve dry eyes and eye irritation caused by reduced tear production, wind, sun exposure, computer use, or certain medical conditions. Helps protect eyes from injury and infection in cases of dry eye syndrome. Also used as a lubricant for artificial eyes and to moisten contact lenses.
Benefits
Provides immediate relief from burning, irritation, and discomfort associated with dry eyes. Creates a protective coating over the eye surface, maintaining moisture and preventing further dryness. Improves comfort during prolonged reading, screen time, or exposure to environmental irritants. Safe for frequent use throughout the day as needed.
Side effects
Most side effects are mild and temporary. Common effects include temporary blurred vision immediately after application, eye redness, mild eye discomfort, or sticky sensation on eyelids. Some patients may experience increased watering of eyes or sensitivity to light. These effects usually resolve quickly. If irritation persists or worsens, consult your doctor.
How to use
Wash hands thoroughly before use. Tilt your head back, pull down the lower eyelid to create a pocket, and instill the prescribed number of drops. Close eyes gently for 1-2 minutes. Do not touch the dropper tip to any surface to avoid contamination. Wait at least 5 minutes between different eye drops if using multiple medications. Always follow your doctor's or pharmacist's instructions regarding frequency of use.
How it works
Carboxymethylcellulose is a water-soluble polymer that acts as a lubricant and artificial tear substitute. It increases the thickness and stability of the tear film on the eye surface. By forming a protective coating, it retains moisture, reduces friction during blinking, and protects the cornea from drying and irritation, thereby providing relief from dry eye symptoms.
Safety advice
Pregnancy and Breastfeeding: Generally considered safe for use during pregnancy and breastfeeding as it is applied topically to the eye with minimal systemic absorption. Driving: May cause temporary blurred vision immediately after application; wait until vision clears before driving. Remove contact lenses before application and wait 15 minutes before reinserting. Do not use if solution changes color or becomes cloudy. Discard the bottle within 4 weeks of opening. Store at room temperature away from direct sunlight.
