Relief of eye irritation, redness, and dryness caused by minor eye irritants such as wind, sun, smoke, or other environmental factors. May also be used for allergic conjunctivitis symptoms and general eye discomfort.
Boric acid acts as a mild antiseptic to maintain eye hygiene and reduce risk of infection, while phenylephrine is a sympathomimetic amine that causes vasoconstriction of blood vessels in the eye, reducing redness and swelling. Together they provide symptomatic relief from eye irritation.
For ophthalmic use only—avoid touching the dropper tip to any surface to prevent contamination. Use with caution in patients with glaucoma, heart disease, or hypertension due to phenylephrine's systemic effects. Discontinue use and consult a healthcare provider if eye pain, vision changes, or irritation persists beyond 72 hours.
