Brimonidine
Brimonidine eye drops reduce fluid production and increase drainage inside the eye. They may be used for glaucoma or ocular hypertension.
Key points
- Brimonidine controls eye pressure only while it is used consistently and monitored.
- It can cause drowsiness, low blood pressure or allergic eye redness, and some antidepressants interact.
- Sudden vision change, severe eye pain, collapse or breathing difficulty needs urgent assessment.
Listings are for comparison only. Suitability and supply depend on clinician and pharmacy checks, stock, destination rules and prescription requirements.
How it works
Brimonidine stimulates alpha-2 receptors in the eye, reducing aqueous-fluid production and increasing outflow.
Important safety checks
Low blood pressure, cardiovascular disease, pregnancy, kidney or liver problems and monoamine-oxidase inhibitors or selected antidepressants require review. Avoid touching the bottle tip, use the prescribed eye only and follow contact-lens instructions. Keep drops away from children because accidental ingestion can be dangerous.
When to seek urgent care
Seek urgent eye care for sudden vision loss, severe pain, marked redness with light sensitivity or eye injury. Seek emergency help for collapse, profound drowsiness, slowed breathing, facial swelling or breathing difficulty.
