What is polyethylene glycol 400/propylene glycol ophthalmic, and what is it used for?
Polyethylene glycol 400/propylene glycol ophthalmic is a type of artificial tears used to treat symptoms of dry eyes.
Polyethylene glycol 400/propylene glycol eye drops are applied topically on the eyes for the temporary relief of irritation and burning from dry eyes, but they do not cure the underlying condition causing dry eye.
Eyes are naturally covered by a fluid film of tear composed of three layers, a mucous (mucin) inner layer, a watery (aqueous) middle layer and a fatty (lipid) outer layer. The tear film protects the eye from the environment and gets rid of irritants, lubricates and provides nutrients to the eye surface, and maintains a smooth eye surface for light refraction. Dry eyes may result from impaired tear production and/or excessive evaporation of natural tears due to aging, medical conditions, dietary deficiencies, or environmental factors.
Polyethylene glycol 400/propylene glycol ophthalmic drops add volume to the tear film and restructure the tear film by forming a protective gel matrix. This reduces tear drainage and evaporation, and keeps the eyes moist. Polyethylene glycol 400/propylene glycol ophthalmic formulations are available over-the-counter (OTC) in multi-dose vials that contain preservatives, and single-dose preservative-free eye drops that are usually more expensive.

- Polyethylene glycol 400/propylene glycol ophthalmic contains propylene glycol, which may be toxic when administered in large amounts, particularly in newborn babies. Use with caution.
