Alphagan P Drug Side Effects and InteractionsChemical Name BRIMONIDINE (bri-MOE-ni-deen)
Alphagan P is an eye drop prescription used to treat open-angle glaucoma and ocular hypertension. It works by reducing the amount of fluid in the eye, thereby decreasing pressure inside the eye.
Alphagan P should not be used without a prescription, nor should it be used on children under 2.
Prior to using Alphagan P, it is important to wash your hands to mitigate the risk of eye infections. Use Alphagan P as prescribed by your doctor. You should not increase or decrease your dosage without consulting your doctor.
To avoid contaminating the dropper, do not touch the dropper to your eye. Contamination of the dropper can result in an infection that could cause vision problems.
If you notice that your prescription of Alphagan P has changed colors or has particles in it, your pharmacies should be able to provide you with a new medicine.
Alphagan Dosage InformationTo apply Alphagan P:
- Tilt your head back and pull down your lower eyelid to create a well. Hold the dropped above the eye, pointing the tip down.
- Squeeze out a drop.
- Close your eyes for 2-3 minutes without blinking or squinting. Press your finger gently on the inside of the corner of your eye to prevent the liquid from draining into your tear duct.
It is important to only use the number of drops indicated by your doctor. If you need to add any other eye drops, wait at least 5 minutes.
If you miss a dose of Alphagan, use it as soon as you remember. However, if it is almost time for your next dosage, skip the missed one.

What is a Generic Drug?
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
