Product Overview

Alphagan P 0.15% Eye Drop is an alpha-adrenergic receptor agonist primarily composed of Brimonidine, used to manage eye pressure in patients with open-angle glaucoma or ocular hypertension. Reducing the production of aqueous humor effectively controls ocular pressure and assists in the management of glaucoma.

Available in strengths of 0.2% and 0.15%, Alphagan P Eye Drops should be applied to the affected eye as directed by a healthcare professional, generally one drop thrice daily. It is suitable for adults and not recommended for children under two years of age or those allergic to any of its components. The eye drops should not be used concurrently with monoamine oxidase inhibitors and require a five-minute interval between other topical eye medications.

Common side effects include blurred vision, burning sensation, conjunctivitis, and dizziness. Individuals should be cautious while engaging in activities that require clear vision immediately after using the medication. If you miss a dose, it should be taken as soon as remembered unless it’s almost time for the next dose. In case of an overdose of the medication, seek immediate medical assistance. Store the eye drops at room temperature (15-25°C) and use within 28 days of opening. Ensure proper disposal of unused medication as advised by a pharmacist. Consult your physician or healthcare provider for personalized guidance on use, potential interactions, and management of side effects.
