Levobunolol is used on its own or together with other medicines to treat increased pressure in the eye.
Instil Levobunolol eye drop solution in the affected eye(s) exactly as directed by your doctor or according to the instructions on the label. Do not use more or less than instructed by your doctor.
To use the eye drop solution:
- Wash your hands thoroughly with soap and water before using the eye drops.
- Tilt your head slightly backwards. With the index finger, pull the lower eyelid away from the eye to form a pouch. Look upward and instil the required number of drops inside the lower eyelid.
- Close your eye and gently press your finger against the corner of the eye (near the nose bridge) for 2 minutes.
- Wipe any excess liquid from your face with a clean tissue.
- Replace and tighten the cap of the bottle.
Do not allow the tip of the dropper of this medicine to touch your eyes, eyelids, or any other surface. Recap the eye drop bottle immediately after use. If the eye drop becomes contaminated, it could cause an infection in your eyes.
If you have been given any other eye drops or medicines to be used together with Levobunolol, wait for at least 5 minutes before using the other medicine.
Do not share your eye drops with anyone else.
Some brands of Levobunolol contain benzalkonium chloride as a preservative. This may discolour soft contact lenses and cause eye irritation. If you are wearing contact lenses, you should remove them before applying the eye drops. Wait for at least 15 minutes before reinserting your lenses.
Levobunolol must be used regularly for it to be effective. Continue using this medicine even when you feel better. Do not stop using it suddenly as this may worsen your condition.
Instil the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.
DO NOT double a dose to make up for a missed dose.
