If you are currently taking another medication similar to this one. If you are unsure, consult your doctor or pharmacist.
Special Considerations for Children:
This medication is not suitable for children under 2 years of age. Do not administer this medication to a child younger than 2 years old.
Additional Guidance:
This list is not exhaustive, and it is crucial to discuss all your medications (prescription, over-the-counter, natural products, and vitamins) and health problems with your doctor and pharmacist.
Ensure it is safe to take this medication with all your other medications and health conditions before starting, stopping, or changing the dose of any medication. Always consult your doctor before making any changes to your medication regimen.
Precautions & Cautions
Before engaging in activities that require alertness or clear vision, such as driving, wait until you understand how this drug affects you.
This medication may mask certain symptoms of low blood sugar, such as a rapid heartbeat, which can increase the risk of severe or prolonged hypoglycemia. This risk is particularly elevated in individuals with diabetes, children, and those who are fasting, including people undergoing surgery, experiencing abnormal eating patterns, or vomiting. If you have concerns, consult your doctor.
Regularly check your eye pressure and vision as instructed by your doctor. Additionally, notify your doctor if you have an eye infection, eye injury, or are scheduled for eye surgery.
Before consuming alcohol, marijuana, or other forms of cannabis, or taking prescription or over-the-counter medications that may impair your reactions, discuss the potential risks with your doctor.
Although rare, severe respiratory problems have occurred in individuals taking this medication, sometimes with fatal outcomes in people with asthma. If you have questions or concerns, consult your doctor.
If you have a history of severe allergic reactions, inform your doctor, as you may be at risk for an even more severe reaction if exposed to the allergen again. If you use epinephrine to treat severe allergic reactions, consult your doctor, as this medication may reduce the effectiveness of epinephrine.
This drug may also make it more challenging to recognize symptoms of hyperthyroidism, such as a rapid heartbeat. If you have hyperthyroidism and suddenly stop taking this medication, your condition may worsen and become life-threatening. Consult your doctor for guidance.
If you are pregnant, plan to become pregnant, or are breastfeeding, discuss the benefits and risks of this medication with your doctor to ensure the best possible outcome for you and your baby.

Monitoring
Baseline Monitoring
Rationale: To establish baseline and assess treatment efficacy.
Timing: Prior to initiation of therapy.
Rationale: To assess ocular health and rule out other conditions.
Timing: Prior to initiation of therapy.
Rationale: To assess baseline cardiovascular status, especially in patients with pre-existing cardiovascular disease, due to potential systemic absorption of timolol.
Timing: Prior to initiation of therapy.
Routine Monitoring
Frequency: Regularly, as determined by ophthalmologist (e.g., 2-4 weeks after initiation, then every 3-6 months)
Target: Individualized target IOP
Action Threshold: IOP above target range or signs of progression.
Frequency: Periodically, especially in patients with cardiovascular or pulmonary disease.
Target: Normal physiological range for the patient
Action Threshold: Significant bradycardia, hypotension, or signs of heart failure.
Frequency: Annually or as clinically indicated.
Target: Stable ocular health
Action Threshold: Signs of ocular irritation, inflammation, or vision changes.
Symptom Monitoring
- Ocular irritation (redness, stinging, burning, itching)
- Blurred vision
- Dry mouth

Special Patient Groups
Pregnancy
Category C. Use only if the potential benefit justifies the potential risk to the fetus. Timolol has been associated with adverse effects in animal studies and has been detected in human breast milk. Brimonidine has shown some reproductive toxicity in animal studies.
Trimester-Specific Risks:
Lactation
Both brimonidine and timolol are excreted in human milk. Due to the potential for serious adverse reactions in nursing infants (especially bradycardia, hypotension, and apnea from timolol), a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Pediatric Use
Contraindicated in infants under 2 years of age due to the potential for increased risk of respiratory depression and bradycardia associated with timolol. Use with extreme caution in children 2-12 years of age due to high incidence and severity of systemic side effects (e.g., somnolence, bradycardia, hypothermia, apnea, hypotension).
Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients. However, greater sensitivity of some older individuals to systemic effects (e.g., cardiovascular, CNS) cannot be ruled out. Monitor for systemic adverse effects.
Clinical Information
Clinical Pearls
- This combination product offers the convenience of two medications in one drop, potentially improving patient adherence and providing enhanced IOP reduction compared to monotherapy.
- Despite being topical, systemic absorption can occur, leading to systemic side effects, particularly those associated with beta-blockade (e.g., bradycardia, hypotension, bronchospasm).
- Proper instillation technique, including nasolacrimal occlusion, can help minimize systemic absorption and maximize local drug concentration.
- Patients should be advised about potential for fatigue, drowsiness, or dizziness, especially at the start of therapy, and cautioned about driving or operating machinery.
- The preservative benzalkonium chloride (BAK) can be absorbed by soft contact lenses; patients should be advised to remove lenses before instillation and wait 15 minutes before reinserting.
Alternative Therapies
- Prostaglandin analogs (e.g., Latanoprost, Travoprost, Bimatoprost)
- Carbonic anhydrase inhibitors (e.g., Dorzolamide, Brinzolamide)
- Alpha-adrenergic agonists (e.g., Brimonidine monotherapy)
- Beta-adrenergic blockers (e.g., Timolol monotherapy, Betaxolol)
- Rho kinase inhibitors (e.g., Netarsudil)
- Miotics (e.g., Pilocarpine)
- Laser trabeculoplasty
- Glaucoma filtration surgery
