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. B2 Doc Eye Drop 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.

How B2 Doc Eye Drop works
B2 Doc Eye Drop is a combination of two medicines: Brinzolamide and Brimonidine. Brinzolamide is an alpha-2 adrenergic receptor agonist while Brimonidine is a sympathomimetic. They work by decreasing the production of aqueous humour (fluid in the eye), thereby lowering the increased eye pressure.
Quick tips
- B2 Doc Eye Drop 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.
