What Brimonidine Tartrate is used for
Brimonidine Tartrate eye drops are prescribed by your eye doctor to help manage conditions that cause increased pressure inside your eye. This high pressure, if left untreated, can damage the optic nerve and lead to vision loss.
- Open-angle glaucoma: This is a common type of glaucoma where the drainage angle of the eye is open, but fluid doesn’t drain properly, leading to increased eye pressure.
- Ocular hypertension: This means you have high pressure inside your eye, but you don’t yet have signs of glaucoma or vision loss. Treating it can help prevent glaucoma from developing.
- Prevention of pressure spikes after laser procedures: Sometimes, after certain laser treatments for the eye, the pressure inside the eye can temporarily increase. Brimonidine Tartrate can be used to help prevent these sudden spikes.
How it works
Brimonidine Tartrate works in two important ways to reduce the pressure inside your eye. Firstly, it helps to reduce the amount of fluid (aqueous humour) that your eye produces. Secondly, it improves the way this fluid drains out of your eye. By doing both, it effectively lowers the overall pressure within the eye, helping to protect your optic nerve from damage.
How it’s used
Brimonidine Tartrate eye drops are typically prescribed for use one drop at a time, either twice or three times a day. Your eye doctor will tell you the exact schedule and strength that is right for you. It is very important to follow your doctor’s instructions carefully for the best results and to ensure the medicine works effectively.
Always follow your ophthalmologist’s exact instructions.

Please note
Must NOT be used in infants and young children — it can cause drowsiness, low blood pressure and breathing difficulty. Long-term use commonly causes an allergic red, itchy eye that means the drop should be stopped. Prescription and supervision required.
Precautions & side effects
While Brimonidine Tartrate is an effective medicine, there are some very important precautions you must be aware of:
- Infants and Young Children: This medicine MUST NOT be used in infants and young children. It can cause serious side effects in this age group, including severe drowsiness, dangerously low blood pressure, and difficulty breathing.
- Allergic Conjunctivitis: It is common for some patients to develop an allergic reaction after using Brimonidine Tartrate for several months. This reaction often appears as red, itchy eyelids and eyes (allergic conjunctivitis). If you notice these symptoms, you must stop using the eye drops and contact your eye doctor immediately. Continuing to use the drops can worsen the allergic reaction.
- Prescription and Supervision: Brimonidine Tartrate is a prescription medicine and should only be used under the supervision of an eye doctor. Do not use it without a prescription or share it with others.
Understanding Glaucoma and Ocular Hypertension
Glaucoma is a group of eye conditions that damage the optic nerve, the nerve that connects your eye to your brain and is essential for good vision. This damage is often caused by abnormally high pressure inside your eye. If left untreated, glaucoma can lead to permanent vision loss and even blindness. The most common type, open-angle glaucoma, often has no early warning signs, which is why regular eye check-ups are so important, especially if you are over 40 or have a family history of glaucoma.
Ocular hypertension means that the pressure inside your eye is higher than normal, but your optic nerve is not yet damaged, and you don’t have any vision loss. However, having ocular hypertension puts you at a higher risk of developing glaucoma in the future. Your eye doctor might prescribe medicines like Brimonidine Tartrate to lower this pressure and reduce your risk.
The goal of treating glaucoma and ocular hypertension is to lower the eye pressure to a safe level, which helps prevent further damage to the optic nerve and preserves your vision. Medicines like Brimonidine Tartrate play a crucial role in achieving this.
How to Use Eye Drops Correctly
Using eye drops correctly is vital for them to work effectively and to avoid contamination. Here’s a step-by-step guide:
- Wash Your Hands: Always wash your hands thoroughly with soap and water before touching your eyes or the eye drop bottle.
- Check the Bottle: Make sure the bottle’s tip is clean and not damaged. Do not let the tip touch any surface, including your eye, fingers, or eyelashes, to prevent contamination.
- Tilt Your Head: Gently tilt your head back or lie down.
- Pull Down Lower Lid: Use one finger to gently pull down your lower eyelid, creating a small pocket.
- Administer the Drop: Hold the eye drop bottle upside down with the tip pointing towards your eye. Look upwards and squeeze the bottle gently to release one drop into the pocket you created in your lower eyelid.
- Close Your Eye Gently: Close your eye gently for a minute or two. Do not blink excessively or squeeze your eye shut, as this can push the medicine out.
- Apply Pressure (Optional but Recommended): You can gently press your finger on the inner corner of your eye (near your nose) for about a minute. This helps prevent the medicine from draining too quickly into your tear duct and entering your bloodstream, allowing more of it to stay in your eye.
- Wipe Excess: Gently wipe away any excess liquid around your eye with a clean tissue.
- Wash Hands Again: Wash your hands again to remove any medicine.
If you are using more than one type of eye drop, wait at least 5-10 minutes between different drops to allow each medicine to be absorbed properly.
General Advice for Eye Drop Users
Maintaining good hygiene and proper storage of your eye drops are essential for your eye health:
- Storage: Store your eye drops as directed by your doctor or the packaging. Generally, they should be kept in a cool, dry place, away from direct sunlight and out of reach of children.
- Expiry Date: Always check the expiry date on the bottle. Do not use expired medicine.
- Discard After Opening: Eye drops usually need to be discarded a certain period after opening (e.g., one month), even if there is still medicine left. This is to prevent infection. Your doctor or pharmacist can advise you on the specific duration for your medicine.
- Do Not Share: Never share your eye drops with anyone else, even if they have similar symptoms. This can spread infections.
- Contact Lenses: If you wear contact lenses, your doctor will advise you whether you need to remove them before instilling the drops and how long you should wait before reinserting them. Many eye drops contain preservatives that can be absorbed by soft contact lenses.
- When to See a Doctor: It is crucial to attend all your follow-up appointments with your eye doctor to monitor your eye pressure and overall eye health. If you experience any new or worsening eye pain, redness, blurred vision, or any other unusual symptoms after starting or while using Brimonidine Tartrate, contact Pristine Eye Hospitals or your eye doctor immediately. Remember the specific warning about allergic conjunctivitis (red, itchy lids) with long-term use – if this happens, stop the drops and consult your doctor right away. Your doctor will guide you on the next steps.
