This medicine may be used alone or with other eye drops. Glaucoma cannot be prevented. Frequent monitoring, regular checkups can help detect the disease in its early stages.

It works by decreasing the production of aqueous humour (fluid in the eye), thereby lowering the increased eye pressure. Stabilized Oxychloro is a preservative.

  • Apply pressure on the corner of the eye (close to the nose) for about 1 minute, immediately after instilling the drop.
  • If you wear soft contact lenses, remove them before putting in these eye drops and wait at least 15 minutes before putting your lenses back in.
  • Do not touch the tip of the dropper to any surface, or to your eye, to avoid contaminating the eye drops.
  • Wait for at least 5-10 minutes before delivering the next medication in the same eye to avoid dilution.
