Brinzolamide/Timolol contains two active substances, brinzolamide and timolol, which work together to reduce pressure within the eye.

Brinzolamide/Timolol is used to treat high pressure in the eyes, also called glaucoma or ocular hypertension, in adult patients that are more than 18 years of age and in whom high pressure in the eyes cannot be controlled effectively by one medicine alone.

Do not use this medicine:
  • if you are allergic to brinzolamide, medicines called sulphonamides (examples include medicines used to treat diabetes, infections and also diuretics (water tablets)), timolol, beta-blockers (medicines used to lower blood pressure or to treat heart disease) or any of the other ingredients of this medicine (listed in section 6).
  • if you have now or have had in the past respiratory problems such as asthma, severe long-lasting obstructive bronchitis (severe lung condition which may cause wheezing, difficulty in breathing and/or long-standing cough) or other types of breathing problems.
  • if you have severe hay fever.
  • if you have a slow heartbeat, heart failure or disorders of heart rhythm (irregular heartbeats).
  • if you have too much acidity in your blood (a condition called hyperchloraemic acidosis).
  • if you have severe kidney problems.

Warnings and precautions

Only use this medicine for dropping in your eye(s).

If signs of serious reactions or hypersensitivity occur, discontinue the use of this product and talk to your doctor.

Talk to your doctor or pharmacist before using this medicine if you have or have had in the past:

  • coronary heart disease (symptoms can include chest pain or tightness, breathlessness or choking), heart failure, low blood pressure.
  • disturbances of heart rate such as slow heartbeat.
  • breathing problems, asthma or chronic obstructive pulmonary disease.
  • poor blood circulation disease (such as Raynaud’s disease or Raynaud’s syndrome).
  • diabetes as timolol may mask signs and symptoms of low blood sugar.
  • overactivity of the thyroid gland as timolol may mask signs and symptoms of thyroid disease.
  • muscular weakness (myasthenia gravis).
  • tell your doctor before you have an operation that you are using Brinzolamide/Timolol as timolol may change effects of some medicines used during anaesthesia.
  • if you have a history of atopy (a tendency to develop an allergic reaction) and severe allergic reactions you may be more sensitive to developing an allergic reaction whilst using Brinzolamide/Timolol and adrenaline may not be as effective to treat an allergic reaction.
    When receiving any other treatment please tell the doctor or nurse that you are taking Brinzolamide/Timolol.
  • if you have liver problems.
  • if you have dry eyes or cornea problems.
  • if you have problems with your kidneys.
  • if you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after using brinzolamide or other related medicines.

Take special care with this medicine

Serious skin reactions including Stevens- Johnson syndrome and toxic epidermal necrolysis have been reported in association with brinzolamide treatment. Stop using brinzolamide and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.

Children and adolescents

This medicine is not recommended for children and adolescents under 18 years.

Other medicines and Brinzolamide/Timolol

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines.

Brinzolamide/Timolol can affect, or be affected by, other medicines you are taking, including other eye drops for the treatment of glaucoma.

Tell your doctor if you are taking or intend to take medicines to lower blood pressure like parasympathomimetics and guanethidine, or other heart medicines including quinidine (used to treat heart conditions and some types of malaria), amiodarone or other medicines to treat heart rhythm disorders and glycosides to treat heart insufficiency. Also tell your doctor if you are taking or intend to take medicines to treat diabetes, or to treat gastric ulcers, antifungal, antiviral or antibiotic medicines, or antidepressants such as fluoxetine and paroxetine.

If you are taking another carbonic anhydrase inhibitor (acetazolamide or dorzolamide), talk to your doctor.

Increase in pupil size when taking Brinzolamide/Timolol and adrenaline (epinephrine) together has been reported occasionally.

Pregnancy and breast-feeding

You should not use this medicine if you are pregnant or might get pregnant, unless your doctor considers it necessary. Talk to your doctor before you use Brinzolamide/Timolol.

Do not use this medicine if you are breast-feeding, timolol may get into your milk.

Ask your doctor for advice before taking any medicine during breast-feeding.

Driving and using machines

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

One of the active ingredients may impair the ability to perform tasks requiring mental alertness and/or physical coordination.

If affected take care when driving or using machines.

Brinzolamide/Timolol contains benzalkonium chloride

This medicine contains 0.0033mg benzalkonium chloride in each drop which is equivalent to 0.01% or 0.1mg/ml.

Benzalkonium chloride is a preservative in Brinzolamide/Timolol that may be absorbed by soft contact lenses and may change the colour of the contact lenses. You should remove contact lenses before using this medicine and put them back 15 minutes afterwards.

Benzalkonium chloride may also cause eye irritation, especially if you have dry eyes or disorders of the cornea (the clear layer at the front of the eye). If you feel abnormal eye sensation, stinging or pain in the eye after using this medicine, talk to your doctor.


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

If you are changing from another eye drop medicine used to treat glaucoma to Brinzolamide/Timolol, you should stop using the other medicine and start using Brinzolamide/Timolol the following day.

Check with your doctor or pharmacist if you are not sure.

To prevent contamination of the dropper tip and the suspension, care must be taken not to touch the eyelids, surrounding areas or other surfaces with the dropper tip. Keep the bottle tightly closed when not in use.

The following measure is useful to limit the amount of medicine that will come into the blood after application of eye drops:

  • Keep the eyelid closed, while simultaneously applying gentle pressure to the corner of the eye next to the nose with a finger for at least 2 minutes.

The recommended dose is one drop in the affected eye or eyes, twice a day.

Only use this medicine in both eyes if your doctor told you to. Take it for as long as your doctor told you to.

How to use
  • Get the bottle and a mirror.
  • Wash your hands.
  • Shake well before use.
  • Twist off the bottle cap. After the cap is removed, if the tamper evident snap collar is loose, remove before using product.
  • Hold the bottle, pointing down, between your thumb and forefinger.
  • Tilt your head back. Pull down your eyelid with a clean finger, 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.
  • Squeeze one drop into the formed pocket (picture 2).

  • After using this medicine, press a finger to the corner of your eye, by the nose for at least 2 minutes. This helps to stop Brinzolamide/Timolol getting into the rest of the body (picture 3).

  • If you use drops in both eyes, repeat the steps for your other eye.
  • Close the bottle cap 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 drop or eye ointment medicines leave at least 5 minutes between each medicine. Eye ointments should be administered last.

If you use more Brinzolamide/Timolol than you should

Rinse your eye with warm water. Do not put in any more drops until it is time for your next regular dose.

You may experience a decreased heart rate, decreased blood pressure, heart failure; difficulty breathing and your nervous system may be affected.

If you forget to use Brinzolamide/Timolol

Continue with the next dose as planned. Do not use a double dose to make up for the forgotten dose. Do not use more than one drop in the affected eye(s) twice daily.

If you stop using this medicine 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.


Like all medicines, this medicine can cause side effects although not everybody gets them.

Stop using this medicine and contact your doctor immediately if you notice any of the following symptoms:
  • if you develop a skin rash, severe skin reaction, or severe redness and itching of the eye.
