systane eye drops preservative free

Common active ingredients in preservative-free Systane drops include polyethylene glycol, propylene glycol, and mineral oil. Formulations may also contain other inactive or supporting components listed on the product label.

For drops: place 1 or 2 drops in the affected eye(s) as needed and blink to distribute. For the nighttime ointment: apply from the small tube before sleep for overnight relief.

The preservative-free nighttime lubricant ointment is designed for overnight use; it forms a protective layer while you sleep to provide extended relief.

Product notes typically advise storing at room temperature and include standard safety warnings such as "Keep out of reach of children." Always follow the label for full storage and safety information.

Preservative-free Systane products are offered as single-use vials, multi-dose bottles, and a nighttime lubricant ointment.

Guidance varies by product: some preservative-free Systane drops are compatible with soft, silicone hydrogel, and gas-permeable lenses; others are labeled "Not Recommended for Contacts." Some products note they can be used before or after contact lens wear but are not marketed as rewetting drops. Check the specific product label for compatibility details.

Some preservative-free Systane formulas are formulated for aqueous-deficient dry eye, while others are intended to address evaporative or mixed (aqueous-deficient plus evaporative) dry eye. Check the product description for the targeted condition.
