Alphagan Information

medically reviewed by Dr. HaVy Ngo, Pharmacist on July 15, 2025.

Alphagan and Brimonidine at CanadaPharmacyOnline.com

Brand Alphagan, manufactured by Allergan (an AbbVie company), is available in many countries worldwide, including Canada and India.

Generic brimonidine is sourced from manufacturers that meet applicable regulatory standards. The specific manufacturer of your dispensed medication may vary.

Important Information about Generic Brimonidine:

Generic brimonidine contains the same active ingredient as the brand-name Alphagan and is required to meet the same safety, effectiveness, and quality standards as the brand-name product. This means it is designed to work in the same way as Alphagan. Studies have demonstrated bioequivalence between generic and brand-name brimonidine, meaning they have comparable absorption rates and overall effects. However, individual responses to any medication can vary. If you have any questions about using generic brimonidine, talk to your doctor or pharmacist.

For more information about generic drug approval and bioequivalence, please refer to Access to Generic Drugs in Canada | Canada.ca

Dosage:

Alphagan (brimonidine) is available as eyedrops (ophthalmic solution) containing 0.2% brimonidine, packaged in a 5 mL bottle.

Your doctor will determine the appropriate dosage based on the individual needs and medical conditions.

Usage:

Alphagan (brimonidine) is a prescription medication used to lower elevated intraocular pressure (IOP) in people with open-angle glaucoma or ocular hypertension. Open-angle glaucoma is a long-term eye condition in which the part of the eye that drains fluid remains open, but the fluid doesn't flow out properly. This causes pressure to slowly build up in the eye, which can eventually damage the nerve (optic nerve) that helps you see. Lowering IOP is crucial for preventing damage to your optic nerve and preserving your vision.

Mechanism of Action:
Alphagan (brimonidine) is an alpha-2 adrenergic agonist that reduces the amount of fluid produced by the eye and facilitates the drainage of fluid, thereby lowering eye pressure. This helps protect the eye from damage caused by high pressure.

Use Alphagan exactly as your doctor prescribes. Do not change your dosage or stop using the medication without consulting your doctor. Follow the instructions in the Patient Medicine Information: https://www.abbvie.ca/content/dam/abbvie-dotcom/ca/en/documents/products/ALPHAGAN_PI_EN.pdf. Consult your doctor for personalized guidance and safe use.
