Special Considerations for Children:
If the patient is under 2 years of age, do not administer this medication. It is not recommended for children younger than 2 years old.
Additional Precautions:
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. Verify that it is safe to take this medication with your existing medications and health conditions. Never start, stop, or modify the dosage of any medication without consulting your doctor.
Precautions & Cautions
This medication may mask certain symptoms of low blood sugar, including 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, undergoing surgery, have a poor appetite, or are experiencing vomiting. If you have any questions or concerns, consult your doctor.
Regularly schedule appointments with your doctor to monitor your eye pressure and vision, as advised. Additionally, notify your doctor if you have an eye infection, eye injury, or are scheduled to undergo eye surgery.
Before consuming alcohol, using marijuana or other cannabis products, or taking prescription or over-the-counter medications that may impair your reactions, discuss the potential risks with your doctor.
Although rare, this medication has been associated with severe respiratory problems, which can be life-threatening, particularly in individuals with asthma. If you have any questions or concerns, consult your doctor.
If you have a history of severe allergic reactions, inform your doctor, as you may be at risk of an even more severe reaction if you are exposed to the allergen again. Furthermore, 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.

Special Patient Groups
Pregnancy
Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Timolol is a Category C drug and has been associated with adverse effects in animal studies and potential for systemic effects in humans. Brimonidine is Category B. Systemic absorption of timolol can lead to fetal bradycardia and growth restriction.
Trimester-Specific Risks:
Lactation
Both brimonidine and timolol are excreted in human milk. Due to the potential for serious adverse reactions in nursing infants (e.g., apnea, bradycardia, CNS depression from brimonidine; bradycardia, hypotension, respiratory depression from timolol), a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother. L3 (moderately safe) for timolol, L3 for brimonidine. Consider alternative or monitor infant closely.
Pediatric Use
Contraindicated in infants and children under 2 years of age due to the potential for severe systemic adverse reactions (e.g., apnea, bradycardia, somnolence, hypotension) associated with brimonidine. Use with caution in children 2-12 years of age due to potential for systemic absorption and associated adverse effects. Safety and efficacy in pediatric patients have not been fully established.
Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients, but greater sensitivity of some older individuals to the systemic effects of timolol cannot be ruled out. Use with caution in patients with underlying cardiovascular or respiratory conditions. Monitor for systemic adverse effects.
Clinical Information
Clinical Pearls
- This combination ophthalmic solution is often used when monotherapy is insufficient to achieve target IOP.
- Patients should be instructed on proper instillation technique to minimize systemic absorption and maximize local effect.
- Advise patients to wait 5 minutes between instilling this product and any other ophthalmic medications.
- Due to the timolol component, caution is advised in patients with a history of asthma, COPD, or certain cardiac conditions. Systemic absorption, though minimal, can still cause significant adverse effects.
- Patients should be monitored for signs of systemic beta-blockade (e.g., bradycardia, hypotension, fatigue) and CNS depression (e.g., somnolence, lethargy).
- The brimonidine component can cause ocular hyperemia (redness) and allergic conjunctivitis in some patients.
Alternative Therapies
- Prostaglandin analogs (e.g., Latanoprost, Travoprost, Bimatoprost)
- Beta-blockers (e.g., Timolol, Betaxolol)
- Alpha-2 adrenergic agonists (e.g., Brimonidine)
- Carbonic anhydrase inhibitors (e.g., Dorzolamide, Brinzolamide, Acetazolamide)
- Rho kinase inhibitors (e.g., Netarsudil)
- Cholinergic agonists (e.g., Pilocarpine)
