"Depression is a common risk for people who have lost their vision from age-related macular degeneration (AMD), but a new study shows that a type of rehabilitation therapy can cut this risk in half. The study was funded by the National Eye Institu"...
Simbrinza Side Effects Center

Simbrinza (brinzolamide/brimonidine tartrate) 1%/0.2% is a combination of a carbonic anhydrase inhibitor and an alpha 2 adrenergic receptor agonist used to reduce intraocular pressure (IOP) in patients with glaucoma or ocular hypertension. Common side effects of Simbrinza include:
- blurred vision,
- eye irritation,
- bad taste in the mouth,
- dry mouth,
- watery eyes,
- itchy eyes,
- red eyes, or
- allergic reaction.
Simbrinza should be shaken well before use. Simbrinza is dose as one drop in the affected eye(s) three times per day. If more than one topically applied medication for eyes, eye medications should be taken at least five minutes apart. Ingredients in Simbrinza are known to interact with certain medications prescribed for depression, including tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs). Simbrinza is also likely to interact with medications that depress the central nervous system (CNS depressants) and some medications prescribed for high blood pressure. Simbrinza has not been studied in pregnant women and should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether Simbrinza is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Simbrinza, 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.

Simbrinza FDA Prescribing Information: Side Effects
Clinical Studies Experience
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to the rates in the clinical studies of another drug and may not refiect the rates observed in practice.
SIMBRINZA In two clinical trials of 3 months duration 435 patients were treated with SIMBRINZA, and 915 were treated with the two individual components. The most frequently reported adverse reactions in patients treated with SIMBRINZA occurring in approximately 3 to 5% of patients in descending order of incidence were blurred vision, eye irritation, dysgeusia (bad taste), dry mouth, and eye allergy. Rates of adverse reactions reported with the individual components were comparable. Treatment discontinuation, mainly due to adverse reactions, was reported in 11% of SIMBRINZA patients.
Other adverse reactions that have been reported with the individual components during clinical trials are listed below.
In clinical studies of brinzolamide ophthalmic suspension 1%, the most frequently reported adverse reactions reported in 5 to 10% of patients were blurred vision and bitter, sour or unusual taste. Adverse reactions occurring in 1 to 5% of patients were blepharitis, dermatitis, dry eye, foreign body sensation, headache, hyperemia, ocular discharge, ocular discomfort, ocular keratitis, ocular pain, ocular pruritus and rhinitis.
The following adverse reactions were reported at an incidence below 1%: allergic reactions, alopecia, chest pain, conjunctivitis, diarrhea, diplopia, dizziness, dry mouth, dyspnea, dyspepsia, eye fatigue, hypertonia, keratoconjunctivitis, keratopathy, kidney pain, lid margin crusting or sticky sensation, nausea, pharyngitis, tearing and urticaria.
Brimonidine Tartrate 0.2%
In clinical studies of brimonidine tartrate 0.2%, adverse reactions occurring in approximately 10 to 30% of the subjects, in descending order of incidence, included oral dryness, ocular hyperemia, burning and stinging, headache, blurring, foreign body sensation, fatigue/drowsiness, conjunctival follicles, ocular allergic reactions, and ocular pruritus.
Reactions occurring in approximately 3 to 9% of the subjects, in descending order included corneal staining/erosion, photophobia, eyelid erythema, ocular ache/pain, ocular dryness, tearing, upper respiratory symptoms, eyelid edema, conjunctival edema, dizziness, blepharitis, ocular irritation, gastrointestinal symptoms, asthenia, conjunctival blanching, abnormal vision and muscular pain.
The following adverse reactions were reported in less than 3% of the patients: lid crusting, conjunctival hemorrhage, abnormal taste, insomnia, conjunctival discharge, depression, hypertension, anxiety, palpitations/arrhythmias, nasal dryness and syncope.
The following reactions have been identified during postmarketing use of brimonidine tartrate ophthalmic solutions in clinical practice. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. The reactions, which have been chosen for inclusion due to either their seriousness, frequency of reporting, possible causal connection to brimonidine tartrate ophthalmic solutions, or a combination of these factors, include: bradycardia, hypersensitivity, iritis, keratoconjunctivitis sicca, miosis, nausea, skin reactions (including erythema, eyelid pruritus, rash, and vasodilation), and tachycardia.
Apnea, bradycardia, coma, hypotension, hypothermia, hypotonia, lethargy, pallor, respiratory depression, and somnolence have been reported in infants receiving brimonidine tartrate ophthalmic solutions [see CONTRAINDICATIONS].
