Betaxolol
(Betaxolol)Betaxolol Overview
Betaxolol is used alone or with other medications to treat high pressure inside the eye due to glaucoma (open-angle type) or other eye diseases (such as ocular hypertension). Lowering high pressure inside the eye helps to prevent blindness. Betaxolol belongs to a class of drugs known as beta blockers and works by decreasing the amount of fluid that is made within the eye.
How to Use Betaxolol
To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface. If you are wearing contact lenses, remove them before using eye drops. Wait at least 15 minutes before replacing your contact lenses. Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place one drop into the pouch, usually twice daily or as directed by your doctor. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of your eye (near the nose) and apply gentle pressure. This will prevent the medication from draining out. Try not to blink and do not rub your eye. Repeat these steps for your other eye if so directed or if your dose is for more than 1 drop. Do not rinse the dropper. Replace the dropper cap after each use. If you are using another kind of eye medication (such as drops or ointments), wait at least 10 minutes before using the other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye. Use Betaxolol regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day. Keep using Betaxolol even if you feel well. Most people with glaucoma or high pressure in the eyes do not feel sick.
