Brinzolamide contains brinzolamide which belongs to a group of medicines called carbonic anhydrase inhibitors. It reduces pressure within the eye.

Brinzolamide eye drops are used to treat high pressure in the eye. This pressure can lead to an illness called glaucoma.

If the pressure in the eye is too high, it can damage your sight.


Do not use brinzolamide

  • if you have severe kidney problems
  • if you are allergic to brinzolamide or any of the other ingredients of this medicine (listed in section 6).
  • if you are allergic to medicines called sulphonamides. Examples include medicines used to treat diabetes and infections and also diuretics (water tablets). Brinzolamide may cause the same allergy.
  • if you have too much acidity in your blood (a condition called hyperchloraemic acidosis)

If you have further questions, ask your doctor for advice.

Warnings and precautions

Talk to your doctor or pharmacist before using brinzolamide:

  • if you have kidney or liver problems.
  • if you have dry eyes or cornea problems.
  • if you are taking other sulphonamide medicines.

Children and adolescents

Brinzolamide is not to be used by infants, children or adolescents under 18 of years of age unless advised by your doctor.

Other medicines and brinzolamide

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

If you are taking another carbonic anhydrase inhibitor (acetazolamide or dorzolamide, see section 1 'What brinzolamide is and what it is used for'), talk to your doctor.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Women who may become pregnant are advised to use effective contraception during brinzolamide treatment. The use of brinzolamide is not recommended during pregnancy or breast-feeding. Do not use brinzolamide unless clearly indicated by your doctor.

Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines

Do not drive or use machines until your vision is clear. You may find that your vision is blurred for a time just after using brinzolamide.

Brinzolamide may impair the ability to perform tasks requiring mental alertness and/or physical coordination. If affected, take care when driving or using machines.

Brinzolamide contains benzalkonium chloride

Brinzolamide contains a preservative (benzalkonium chloride) which may cause eye irritation and is known to discolour soft contact lenses. Contact with soft contact lenses should be avoided. If you wear contact lenses you should remove prior to the application of brinzolamide and wait at least 15 minutes after instillation of the dose before putting your lenses back in.


Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.

Only use brinzolamide for your eyes. Do not swallow or inject.

The recommended dose is

1 drop in the affected eye or eyes, twice a day - morning and night.

Use this much unless your doctor told you to do something different. Only use brinzolamide in both eyes if your doctor told you to. Use it for as long as your doctor told you to.

How to use

  • Get the brinzolamide bottle and a mirror
  • Wash your hands
  • Shake the bottle and twist off the cap. After the cap is removed, if tamper evident snap collar is loose, remove before using the product.
  • Hold the bottle, pointing down, between your thumb and middle finger
  • Tilt your head back. Pull down your eyelid with a clean figure, until there is a 'pocket' between the eyelid and your eye. The drop will go in here (picture 1)
  • Bring the bottle tip close to the eye. Use the mirror if it helps
  • Do not touch your eye or eyelid, surrounding areas or other surfaces with the dropper. It could infect the drops
  • Gently press on the base of the bottle to release one drop of brinzolamide at a time.
  • Do not squeeze the bottle: it is designed so that a gentle press on the bottom is all that it needs (picture 2).
  • After using brinzolamide, press a finger to the corner of your eye, by the nose (picture 3) for at least 1 minute. This helps to stop brinzolamide getting into the rest of the body.
  • If you take drops in both eyes, repeat the steps for your other eye.
  • Put the bottle cap back on firmly immediately after use.
  • Use up one bottle before opening the next bottle.

If a drop misses your eye, try again.

If you are using other eye drops, leave at least 5 minutes between putting in brinzolamide and the other drops. Eye ointments should be administered last.

If you use more brinzolamide than you should

If you get too much in your eyes, rinse it all out with warm water. Do not put in any more drops until it's time for your next regular dose.

If you forget to use brinzolamide

Use a single drop as soon as you remember, and then go back to your regular routine.

Do not use a double dose to make up for a forgotten dose.

If you stop using brinzolamide

If you stop using brinzolamide without speaking to your doctor, the pressure in your eye will not be controlled which could lead to loss of sight.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
