Carboxymethylcellulose
About Carboxymethylcellulose
Carboxymethylcellulose is a sterile ophthalmic solution used to relieve dry, irritated eyes. It acts as a lubricant to protect your eyes from dryness, wind, sun, and computer screen strain. This medicine helps maintain the proper moisture balance on the surface of your eyes to prevent discomfort.
You can use Carboxymethylcellulose as often as needed throughout the day, or as directed by your doctor. It is typically applied as one or two drops in the affected eye(s) whenever you feel dryness or irritation. Making simple lifestyle adjustments, such as taking regular breaks during screen time and drinking plenty of water, can also significantly improve your comfort.
Most people use this medicine without any major issues, but you may experience temporary mild stinging or blurred vision immediately after applying it. If you experience severe eye pain, changes in your vision, or persistent redness, stop using the drops and consult your doctor right away.

If you use other eye drops or eye ointments, always wait at least 5 to 10 minutes between applying each product to prevent them from washing each other out. If you are pregnant, breastfeeding, or treating an elderly family member, it is best to consult your doctor or pharmacist before starting.
