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. Levobunolol belongs to a class of drugs known as beta blockers and works by decreasing the amount of fluid production within the eye.
How to use Levobunolol HCL Drops
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 as directed by your doctor, usually once or twice daily. 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 5 to 10 minutes before using the other medications. Use eye drops before eye ointments to allow the eye drops to enter the eye.
Use this medication 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 this medication even if you feel well. Most people with glaucoma or high pressure in the eyes do not feel sick.
