How should I use Alphagan P?
Use Alphagan P exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Wash your hands before using the eye drops.
To apply the Alphagan P eye drops:
Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye with the tip down. Look up and away from the dropper and squeeze out a drop.
Close your eyes for 2 or 3 minutes with your head tipped down, without blinking or squinting. Gently press your finger to the inside corner of the eye for about 1 minute, to keep the liquid from draining into your tear duct.
Use only the number of drops your doctor has prescribed. If you use more than one drop, wait about 5 minutes between drops.
Wait at least 5 minutes before using any other eye drops your doctor has prescribed.
Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.
Do not use the Alphagan P eye drops if the liquid has changed colors or has particles in it. Call your pharmacist for new medicine.
Tell your doctor right away if you have any eye injury or infection, or if you need to have any type of surgery, especially eye surgery.
Store Alphagan P eye drops at room temperature away from moisture and heat. Do not freeze. Keep the bottle tightly closed when not in use.
