SIMBRINZA is used to treat high pressure in the eyes in adult patients that are more than 18 years of age with open-angle glaucoma or ocular hypertension.

  • if you are taking monoamine oxidase (MAO) inhibitors or certain antidepressants. You must inform your doctor if you are taking any antidepressant drug.
  • if you have severe kidney problems
  • if you have too much acidity in your blood (a condition called hyperchloraemic acidosis)
  • in babies and infants aged less than 2 years and in children 2 to 17 years of age.

If you wear contact lenses

There is a preservative in SIMBRINZA (benzalkonium chloride) that may be absorbed by and can discolour soft contact lenses and may cause eye irritation.

Therefore, do not wear contact lenses while using SIMBRINZA.

Wait 15 minutes after using SIMBRINZA before putting your lenses back in.

Drugs that may interact with SIMBRINZA include other eye drops for the treatment for glaucoma, medicines to lower blood pressure, heart medicines including digoxin (used to treat heart conditions), other medicines for glaucoma that also treat altitude sickness known as acetazolamide, methazolamide and dorzolamide, antiviral or antibiotic medicines, acetylsalicylic acid, monoamine oxidates (MAO) inhibitors, or antidepressants such as amitriptyline, nortriptyline, clomipramine and mianserin.

Proper Use of this Medication

Always use SIMBRINZA exactly as your doctor has told you. Check if you are not sure.

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

Usual adult dose:

One drop in the eye or eyes, twice a day - morning and night. Use at the same times each day.

Only use SIMBRINZA 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 SIMBRINZA bottle and a mirror.
  • Wash your hands before use.
  • Shake well before use.
  • Twist off the bottle cap. Remove security-ring if loose.
  • Hold the bottle, pointing down, between your thumb and fingers.
  • 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. If the tip of the dispensing container contacts the eye or surrounding structures, it can become contaminated by common bacteria known to cause eye infections. It could infect the drops. Serious damage to the eye and subsequent loss of vision may result from using contaminated solutions.
  • Gently press on the base of the bottle to release one drop of SIMBRINZA 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 SIMBRINZA, press a finger into the corner of your eye, by the nose (picture 3) for up to 1 minute. This helps to stop SIMBRINZA getting into the rest of the body.
  • 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.
  • Do not use for more than 125 days after opening the 10 mL bottle or 32 days after opening the 5 mL bottle.
  • If solution changes color, do not use. Do not use the product after the expiration date marked on the bottle.

If a drop misses your eye, try again.

If you are using other eye drops, wait at least 5 minutes between using SIMBRINZA and the other drops.

SIMBRINZA contains a preservative called benzalkonium chloride which may discolour soft contact lenses. If you wear contact lenses, remove them before using SIMBRINZA. Wait 15 minutes after using the drops before you put your lenses back in.


If you use more SIMBRINZA 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.

In case of drug overdose, particularly oral ingestion, contact your doctor, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.

Missed Dose:

If you forget to use SIMBRINZA, continue with the next dose as planned. Do not use a double dose to make up for the missed dose. Do not use more than one drop in the affected eye(s) two times a day.

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