This medication 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.
Use this medication in the affected eye(s) as directed
by your doctor, usually twice daily.
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.
Shake the bottle well before using. 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. 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.
Wait several minutes for your vision to clear before
driving or operating machinery.
Use this medication regularly in order to get the most
benefit from it. To help you remember, use it at the same times each day.
Keep using this medication even if you feel well. Most people with glaucoma
or high pressure in the eyes do not feel sick.
Temporary stinging/discomfort of the eye,
watery/dry/itchy/red eyes, blurred vision, feeling as if something is in
the eye, crusting of eyelashes, headache, trouble sleeping, or dizziness
may occur. If any of these effects last or get worse, tell your doctor or
pharmacist promptly.
