BRIMONIDINE

BRIMONIDINE: Brimonidine is a medication commonly used to treat high eye pressure (intraocular pressure) in patients with open-angle glaucoma or ocular hypertension. It is sold under the brand name Alphagan.

The mechanism of action of brimonidine involves reducing the production of fluid (aqueous humor) in the eye and increasing the drainage of fluid, which helps to lower the intraocular pressure. This is achieved by activating alpha-2 adrenergic receptors on the surface of the ciliary body, which is responsible for the production of aqueous humor.

The typical dose of brimonidine for adults is one drop in the affected eye(s) three times a day. The frequency may be adjusted based on the individual’s response and the recommendation of their healthcare provider.

Like any medication, brimonidine may cause side effects. Common side effects include burning or stinging sensation in the eye, eye redness, itching, dry mouth, blurred vision, and headache. These side effects are usually mild and temporary.

Some individuals may experience more severe or less common side effects, such as allergic reactions (itching, hives, swelling), eye pain, increased sensitivity to light, dizziness, fatigue, low blood pressure, depression, or irregular heartbeat. If any of these more serious side effects occur, it is important to seek immediate medical attention.

It is essential to inform your healthcare provider about any other medications, including over-the-counter drugs, you are taking, as there may be potential drug interactions. Brimonidine should only be used under medical supervision, and the prescribed dosage and frequency should not be altered without consulting a healthcare provider.
