Benzalkonium / Tyloxapol
Benzalkonium/Tyloxapol is an ophthalmic medication combination used primarily in eye drop formulations. Benzalkonium chloride serves as a preservative to maintain sterility, while Tyloxapol acts as a surfactant to help disperse active ingredients and improve contact with the eye surface. This combination is commonly found in lubricating eye drops and artificial tear preparations for dry eye relief.

Used for temporary relief of dry, irritated eyes; artificial tear supplementation; and general eye lubrication. Commonly formulated for conditions involving insufficient tear production or poor tear film stability.
Tyloxapol acts as a non-ionic surfactant to lower surface tension and improve spreading of the solution across the corneal surface. Benzalkonium chloride preserves the formulation by preventing microbial contamination, extending the product's shelf life.
For ophthalmic use only; avoid touching the dropper tip to any surface to prevent contamination. Contact lens compatibility varies by formulation—consult with an eye care professional. Discontinue use and seek medical attention if eye pain, vision changes, or persistent irritation occurs. Not a replacement for medical treatment of underlying eye conditions.
