About Thealoz Duo Dry Eye Drops

Thealoz Duo Dry Eye Drops are a sterile, preservative-free, and hypotonic ophthalmic solution designed to provide advanced protection, hydration, and lubrication for the ocular surface. It is specifically formulated to manage symptoms of moderate to severe dry eye syndrome by utilizing a unique dual-action formula. By combining Trehalose (3%) and Sodium Hyaluronate (0.15%), these drops mimic the natural protective mechanisms of the eye, offering immediate comfort and long-lasting relief from grittiness, stinging, and irritation.

Thealoz Duo is suitable for adults, children, and even those who are pregnant or breastfeeding. It is available in a specialized multi-dose ABAK bottle:

What Is Thealoz Duo Used For?

Thealoz Duo is used to treat dry eye symptoms such as discomfort, stinging, or irritation. These symptoms can be caused by external factors like wind, smoke, pollution, dust, sunny or cold weather, dry heat, or air conditioning. It is also highly effective for eye strain caused by long periods of computer work or for soothing the eyes following ophthalmic surgery (such as LASIK).

Who Is Thealoz Duo Suitable For?

Thealoz Duo is suitable for individuals with sensitive eyes who require long-term relief without the irritation of preservatives. It is compatible with all types of contact lenses.

Do not use Thealoz Duo if you:

  • Are allergic (hypersensitive) to trehalose, sodium hyaluronate, or any other ingredients.

Speak to a healthcare professional before use if you:

  • Are using other eye medications (wait at least 10 minutes between applications).
  • Suffer from a severe eye infection or injury.
  • Experience persistent eye pain or changes in vision.

How to Use Thealoz Duo Dry Eye Drops

  1. Wash your hands thoroughly before application.
  2. Remove the tamper-evident ring and pull off the cap.
  3. Tilt your head back and gently pull down the lower eyelid.
  4. Invert the bottle and squeeze until a single drop is released into the eye.
  5. Gently close your eye and replace the cap immediately after use.

The ABAK bottle ensures the solution remains sterile without the need for preservatives. Note that the first drop may take longer to appear due to the specialized filter system.

Possible Side Effects of Thealoz Duo

Thealoz Duo is very well tolerated, though rare side effects may occur:

  • Mild eye irritation or redness.
  • Brief periods of blurred vision immediately after use.

If you experience severe reactions or persistent discomfort, stop using the drops and consult an optometrist or doctor.

Warnings and Precautions

  • Do not exceed the frequency of use recommended by your specialist.
  • Avoid contact between the bottle tip and the eye or eyelids to prevent contamination.
  • Do not inject or swallow the solution.
  • If vision is blurred after use, wait until it clears before driving or using tools.
  • Keep the bottle away from heat sources and direct sunlight.

Storage Instructions

  • Store between 8°C and 30°C.
  • Keep out of the sight and reach of children.
  • Do not use after the expiry date shown on the box.
  • Discard the bottle 6 months after first opening.

Important Information

  • 100% Preservative-free and Phosphate-free.
  • Clinically proven to provide 24-hour protection for the ocular surface.
  • Safe for use with all contact lenses (no need to remove them).
