What Brinzolamide + Timolol is used for

Brinzolamide + Timolol eye drops are prescribed to help manage a condition called open-angle glaucoma. This medicine is specifically used when your doctor believes that two different medications are needed to effectively lower your eye pressure, and if you find other similar eye drops (like those containing dorzolamide) cause too much stinging.

Open-angle glaucoma: This is a common eye condition where the pressure inside your eye (intraocular pressure) becomes too high. If left untreated, this high pressure can damage the optic nerve, which connects your eye to your brain. Damage to the optic nerve can lead to permanent vision loss. Brinzolamide + Timolol helps to reduce this pressure, protecting your vision.

How it works

Brinzolamide + Timolol is a combination eye drop that contains two different medicines, Brinzolamide and Timolol, which work together to lower the pressure inside your eye. Both of these medicines achieve this by reducing the amount of fluid produced within your eye. Your eye constantly produces a fluid called aqueous humour, and when this fluid doesn’t drain properly or too much is produced, the pressure inside your eye can increase. By reducing the production of this fluid, Brinzolamide + Timolol helps to bring your eye pressure down to a safer level, which is crucial for protecting your vision from the damaging effects of glaucoma.

How it’s used

Always use Brinzolamide + Timolol eye drops exactly as your doctor or pharmacist has told you. It is very important to follow their instructions carefully to ensure the medicine works effectively and safely.

Dosing: The usual dose is one drop in the affected eye(s) twice a day. Your doctor will tell you exactly which eye(s) to treat and for how long.

Important steps for using your eye drops:

Shake well: Before each use, make sure to shake the bottle well. This is because Brinzolamide + Timolol is a suspension, meaning the medicine particles are suspended in the liquid and need to be evenly distributed.
Wash your hands thoroughly with soap and water before handling the eye drop bottle.
Tilt your head back slightly and pull down your lower eyelid to create a small pocket.
Hold the dropper tip directly over your eye. Try not to let the tip touch your eye, eyelid, or any other surface, as this can contaminate the drops.
Gently squeeze the bottle to release one drop into the pocket you created.
Close your eye gently and, immediately after instilling the drop, gently press your finger on the inner corner of your eye (near your nose) for 1-2 minutes. This technique, called punctal occlusion, helps to reduce the amount of medicine absorbed into your bloodstream, which is particularly important for this medicine.
Wipe away any excess liquid from your cheek with a clean tissue.
If you need to use the drops in both eyes, repeat the process for the other eye.
Replace the cap tightly on the bottle immediately after use.
Do not stop using these eye drops suddenly without consulting your doctor, as this could lead to an increase in your eye pressure and potentially worsen your glaucoma.

Always follow your ophthalmologist’s exact instructions.

Please note

Contains a beta-blocker that can be absorbed into the body. Tell your doctor if you have asthma, COPD, a slow heart rate or heart disease. After instilling, gently press the inner corner of the eye for 1-2 minutes to reduce absorption. Do not stop suddenly without advice.

Precautions & side effects

While Brinzolamide + Timolol eye drops are effective for glaucoma, there are important precautions you need to be aware of to ensure your safety and the effectiveness of the treatment. Always discuss your full medical history with your doctor before starting this medication.

Shake well: Remember to shake the bottle well before each use, as this is a suspension and the medicine needs to be evenly mixed.
Less stinging: Patients often find that these eye drops cause less stinging compared to other similar combinations, such as those containing dorzolamide.
Contains a beta-blocker: This medicine contains Timolol, which is a type of medicine called a beta-blocker. Beta-blockers can be absorbed into your body through the eyes and affect other parts of your body.
Tell your doctor if you have certain conditions: It is crucial to inform your doctor if you have any of the following conditions, as beta-blockers can potentially worsen them:
- Asthma or Chronic Obstructive Pulmonary Disease (COPD): Beta-blockers can affect breathing and may not be suitable for patients with these respiratory conditions.
- A slow heart rate or heart disease: Beta-blockers can slow down the heart rate and affect heart function, so they should be used with caution in patients with heart conditions.
Reduce systemic absorption: After putting in the eye drops, gently press the inner corner of your eye (near your nose) for 1-2 minutes. This simple step helps to reduce the amount of medicine that gets absorbed into your bloodstream, thereby minimizing potential side effects on other parts of your body.
Do not stop suddenly: It is very important not to stop using Brinzolamide + Timolol eye drops suddenly without your doctor’s advice. Stopping abruptly can cause your eye pressure to increase, potentially leading to further damage to your optic nerve and vision. Your doctor will guide you on how to safely discontinue the medication if needed.
Prescription only: This is a prescription medicine and should only be used under the guidance of a qualified eye doctor.
High warning level: Due to the potential for systemic absorption and interactions with other medical conditions, this medicine carries a high warning level. Always follow your doctor’s instructions diligently and report any new or worsening symptoms.

Understanding Glaucoma and Why Treatment is Important

Glaucoma is a group of eye conditions that damage the optic nerve, the vital connection between your eye and your brain. This damage is often caused by abnormally high pressure inside your eye, known as intraocular pressure. In most cases, glaucoma develops slowly over many years and often has no early warning signs or symptoms. This is why it’s sometimes called the ‘silent thief of sight.’ By the time people notice vision problems, significant and irreversible damage may have already occurred. Regular eye check-ups, especially if you are over 40 or have a family history of glaucoma, are crucial for early detection. If diagnosed, timely and consistent treatment, like using eye drops such as Brinzolamide + Timolol, is essential to lower eye pressure and prevent further damage to your optic nerve, thereby preserving your vision. While glaucoma cannot be cured, its progression can be effectively managed with proper treatment.

Correct Way to Use Eye Drops

Using eye drops correctly is vital for them to work effectively and to prevent contamination. Here’s a step-by-step guide to help you:

Wash Your Hands: Always start by washing your hands thoroughly with soap and water to prevent introducing germs into your eye.
Prepare the Bottle: If your eye drop is a suspension (like Brinzolamide + Timolol), shake the bottle well before each use to ensure the medicine is evenly mixed.
Open Carefully: Twist off the cap, making sure not to touch the dropper tip with your fingers or any other surface. Contamination of the tip can lead to eye infections.
Position Yourself: Tilt your head back slightly or lie down. With the index finger of one hand, gently pull down your lower eyelid to create a small pocket.
Instil the Drop: Hold the dropper bottle upside down with your other hand, positioning the tip directly over your eye. Look upwards. Gently squeeze the bottle to release just one drop into the pocket formed by your lower eyelid. Avoid letting the tip touch your eye, eyelashes, or any other surface.
Close and Press: Immediately after instilling the drop, close your eye gently. Do not blink excessively or squeeze your eye shut tightly, as this can push the medicine out. Gently press your finger on the inner corner of your eye (near your nose) for 1-2 minutes. This helps the medicine stay in your eye and reduces its absorption into your bloodstream.
Wipe Excess: Use a clean tissue to gently wipe away any excess liquid from your eyelid or cheek.
Recap: Replace the cap tightly on the bottle immediately after use.
Wait Between Drops: If you need to use more than one type of eye drop, wait at least 5-10 minutes between different medications. This allows each drop to be absorbed properly.

General Eye Care, Hygiene, and When to Seek Help

Maintaining good eye hygiene and being aware of when to seek medical attention are important aspects of managing your eye health, especially when using eye medications. Always store your eye drops at room temperature, away from direct sunlight and heat, unless otherwise specified by your pharmacist or doctor. Do not store them in the refrigerator unless instructed to do so. Always check the expiry date on the bottle and discard any opened bottle after the recommended period (usually 28 days after opening, even if there is still medicine left). This is because once opened, eye drops can become contaminated over time. Never share your eye drops with anyone else, as this can spread infections.

It’s important to know when to contact your eye doctor. You should seek immediate medical advice if you experience any of the following:

Sudden changes in vision or vision loss.
Severe eye pain.
Redness, swelling, or discharge from the eye that worsens or doesn’t improve.
Increased sensitivity to light.
Seeing halos around lights.
Any new or unusual symptoms after starting your eye drops, or if you suspect an allergic reaction.
If your eye condition seems to be worsening despite using the medication as prescribed.

Regular follow-up appointments with your eye doctor are crucial to monitor your eye pressure and overall eye health, and to ensure your treatment plan remains effective. Do not hesitate to ask your doctor or pharmacist any questions you may have about your medication or eye condition.
