Uses of Brishield Eye Drop

Benefits of Brishield Eye Drop

Treatment of Glaucoma
Glaucoma is an eye disease that damages the optic nerve which is essential for proper vision. This damage is often caused by an abnormally high pressure in the eye. Brishield (Bak Free) is used to reduce swelling and pressure inside the eye. This helps prevent complications of glaucoma such as blindness and improves the vision. 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.
Treatment of Ocular hypertension
Ocular hypertension is a condition where the pressure inside the eye is higher than normal eye pressure due to fluid build-up. Brishield (Bak Free) increases the flow of fluid from inside the eye into the bloodstream thereby lowering the increased eye pressure. This prevents further damage or complications such as change in vision or even loss of vision. You should only use Brishield (Bak Free) in the affected eye and take it regularly as prescribed by your doctor.

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

How to use Brishield 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 Brishield Eye Drop works

Brishield (Bak Free) is a combination of two medicines: Timolol and Brimonidine. Timolol is a beta blocker while Brimonidine is a sympathomimetic. They work by decreasing the production of aqueous humor (fluid in the eye), thereby lowering the increased eye pressure.

Quick tips

  • Brishield (Bak Free) is a combination of two medicines that lowers high pressure in the eye and reduces the risk of vision loss.
  • 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.
  • It may cause short term blurring of vision when first used. Use caution before driving or using machines.
  • It may cause temporary burning or itching sensation in the eye. Inform your doctor if this does not go away.
  • Make sure to use within 4 weeks of opening the bottle.
