Product introduction

Never use DORtas Eye Drop if the seal is broken before you use it for the first time. Wash your hands before using it and shake the bottle well before each use. Make sure you remove contact lenses if you wear them and wait for at least 15 minutes before putting them back. Do not stop using this medicine without asking your doctor. Otherwise, the pressure in your eye will not be controlled and this could damage your sight.

The most common side effects of DORtas Eye Drop are a stinging and burning sensation and a bitter taste in your mouth. Sometimes people experience more general effects such as headache, nausea, tiredness, or eye irritation. If your vision is blurred or you have other changes in sight for a time, do not drive until your vision is clear.

Do not use this medicine if you have severe kidney problems or are allergic to medicines called sulphonamides. Talk to your doctor before taking it if you have liver problems, dry eyes, or cornea problems. Do not use other eye medications unless your doctor tells you to.

Uses of DORtas Eye Drop

Benefits of DORtas Eye Drop

Glaucoma
Glaucoma is an eye condition where increased pressure within the eye (intraocular pressure) can damage the optic nerve, potentially leading to vision loss if left untreated. DORtas Eye Drop is used to manage this condition by reducing the fluid production inside the eye, thereby lowering the pressure. Controlling eye pressure helps slow down or prevent further damage to the optic nerve, preserving vision and supporting long-term eye health.

Side effects of DORtas Eye Drop

Most side effects do not require any medical attention and disappear as your body adjusts to the medicine. Consult your doctor if they persist or if you’re worried about them
Common side effects of DORtas
  • Stinging in the eyes
  • Burning eyes
  • Bitter taste

How to use DORtas Eye Drop

This medicine is for external use only. Use it in the dose and duration as advised by your doctor. Check the label for directions before use. Hold the dropper close to the eye without touching it. Gently squeeze the dropper and place the medicine inside the lower eyelid. Wipe off the extra liquid.

How DORtas Eye Drop works

DORtas Eye Drop is a carbonic anhydrase inhibitor. It works by decreasing the production of aqueous humour (fluid in the eye), thereby lowering the increased eye pressure.

Quick tips

  • DORtas Eye Drop helps lower high pressure in the eye and reduce the risk of vision loss.
  • For best results, put one drop 2-3 times daily in the affected eye(s).
  • Apply pressure on the corner of the eye (close to the nose) for about 1 minute, immediately after instilling the drop. This minimizes the risk of side effects.
  • Do not touch the tip of the dropper to any surface, or to your eye, to avoid contaminating the eye drops.
  • Remove contact lenses before using DORtas Eye Drop, and wait at least 15 minutes before re-inserting them.
  • When applying multiple eye medications, wait for at least 5-15 minutes before delivering the next medication in the same eye to avoid dilution of the medicine.
