What BrinzoQuin is used for

BrinzoQuin Eye Drops contain the active ingredient brinzolamide, which belongs to a class of medicines known as “carbonic anhydrase inhibitors”.

BrinzoQuin Eye Drops are used, either alone or in combination with other eye drops/medicines, to lower high pressure inside the eye(s) and to treat open-angle glaucoma or hypertension (high pressure) in the eye.

Glaucoma is a condition in which the pressure of fluid in the eye may be high. However, some people with glaucoma may have normal eye pressure.

Glaucoma is usually caused by a build up of the fluid which flows through the eye. This build up occurs because the fluid drains out of the eye more slowly than it is being pumped in. Since new fluid continues to enter the eye, joining the fluid already there, the pressure continues to rise. This raised pressure may damage the back of the eye resulting in gradual loss of sight. Damage can progress so slowly that the person is not aware of this gradual loss of sight. Sometimes even normal eye pressure is associated with damage to the back of the eye.

There are usually no symptoms of glaucoma. The only way of knowing that you have glaucoma is to have your eye pressure, optic nerve and visual field checked by an eye specialist or optometrist. If glaucoma is not treated, it can lead to serious problems, including total blindness. In fact, untreated glaucoma is one of the most common causes of blindness.

BrinzoQuin Eye Drops lower the pressure within the eye by reducing the production of fluid.

Although BrinzoQuin Eye Drops help to control your glaucoma, they do not cure it.

For more information about glaucoma, contact Glaucoma Australia Inc. (PO BOX 420, Crows Nest 1585 telephone 1800 500 880).

Ask your doctor if you have any questions about why BrinzoQuin has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is only available with a doctor’s prescription.

BrinzoQuin Eye Drops are not addictive.

  • High dose of salicylate-containing medicines which are used to relieve pain
  • Other medicines known as “carbonic anhydrase inhibitors” that you take to treat glaucoma.

These medicines may be affected by BrinzoQuin Eye Drops, or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines.

If you are taking another carbonic anhydrase inhibitor (acetazolamide or dorzolamide) or medicines that are nonsteroidal anti-inflammatory drugs (NSAIDs) or salicylates, talk to your doctor or healthcare provider.

Your doctor or pharmacist has more information on medicines to be careful with or avoid while using this medicine.

How to use BrinzoQuin

Follow all directions given to you by your doctor or healthcare provider carefully.

They may differ from the information contained in this leaflet.

If you do not understand the instructions on the box ask your doctor or pharmacist for help.

How much to use

The usual dose of BrinzoQuin Eye Drops is one drop in the affected eye(s) twice a day. This will normally be in the morning and at night. Your doctor will tell you how many drops you need to use each day.

After using BrinzoQuin Eye Drops wait at least 5 minutes before putting any other eye drops in your eye(s). Eye ointment should be administered last.

If you are being changed from one eye drop to another, follow your doctor’s instructions carefully as to when to stop the old drops and when to start the new drops.

If you are unsure about when, or how, to stop using BrinzoQuin Eye Drops you should talk to your doctor.

Do not use BrinzoQuin Eye Drops more often than your doctor or pharmacist has told you.

How to use BrinzoQuin

Follow these steps to use BrinzoQuin Eye Drops:

  1. Wash your hands thoroughly.
  2. Immediately before using a bottle for the first time, break the safety seal around the neck area and throw the loose plastic ring away.
  3. Shake the bottle.
  4. Remove the cap from the bottle.
  5. Hold the bottle upside down in one hand between your thumb and middle finger (see Diagram 1).

  1. Tilt your head back and look up.
  2. Using your other hand, gently pull down your lower eyelid to form a pouch/pocket.

  1. Place the dropper tip close to, but not touching, your eye. Release one drop into the pouch/pocket formed between your eye and eyelid by gently tapping or pressing the base of the bottle with your forefinger (see Diagrams 2 and 3).
  2. Close your eye gently without blinking and press on the inside corner of the eye with the pad of your index finger for two minutes.
  3. If necessary, repeat steps 4-8 for your other eye.
  4. Replace the cap on the bottle, closing it tightly.
  5. Wash your hands again with soap and water to remove any residue.

You may feel a slight burning sensation in the eye shortly after using BrinzoQuin Eye Drops. If this persists, or is very uncomfortable, contact your doctor or pharmacist.

Do not touch the tip of the dropper to your eye or to any other surface. This will help to prevent your eye drops becoming dirty or contaminated.

When to use it

Use BrinzoQuin Eye Drops at about the same time every day unless your doctor tells you otherwise.

Using your eye drops at the same time each day will have the best effect on your eye pressure. It will also help you remember when to use the eye drops.

How long to use it

BrinzoQuin Eye Drops help control your condition but will not cure it. BrinzoQuin Eye Drops must be used every day. Continue using BrinzoQuin Eye Drops for as long as your doctor prescribes.

If you forget to use it

If you forget to use BrinzoQuin Eye Drops you should put the drops that you missed in your eye(s) as soon as you remember and then go back to using them as recommended by your doctor.

If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to.

Otherwise, use the drops as soon as you remember, and then go back to using them as you would normally.

If you are not sure whether to skip the dose, talk to your doctor or pharmacist.

Do not use double the amount to make up for the dose that you missed. Using multiple doses may cause unwanted side effects.

If you use too much (overdose)

If you accidentally put several drops in your eye(s), immediately rinse your eye(s) with warm water.

If you think that you or anyone else may have swallowed any or all of the contents of a bottle of BrinzoQuin Eye Drops, immediately telephone your doctor or Poisons Information Centre on 131126 for advice or go to Accident and Emergency at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

After using BrinzoQuin


Keep your eye drops in a cool place where the temperature stays below 25°C. Do not freeze the eye drops.

Do not leave BrinzoQuin Eye Drops in the car, the bathroom or in other warm, damp places. Heat and dampness can destroy some medicines.

A locked cupboard at least one and a half metres above ground is good place to store medicines.

Keep it where children cannot reach it.

Put the top back on the bottle right away after use to avoid contaminating the eye drops. Do not leave the top off the bottle for any length of time.


Write the date on the bottle when you open the eye drops and throw out any remaining solution after four weeks.

Open a new bottle every four weeks. Eye drops contain a preservative which helps prevent germs growing in the solution for the first four weeks after opening the bottle. After this time there is a greater risk that the drops may become contaminated and cause an eye infection.

If your doctor tells you to stop using the eye drops or they have passed their expiry date, ask your pharmacist what to do with any remaining solution.
