About levobunolol eye drops
|Type of medicine||Beta-blocker eye preparation|
|Used for||Chronic open angle glaucoma|
|Available as||Eye drops and single-dose unit eye drops|
In chronic open angle glaucoma there is damage to the optic nerve at the back of your eye. It is usually caused by an increase in pressure within your eye. Levobunolol eye drops work by lowering the pressure in your eye. They do this by reducing the amount of fluid that you make that fills the front part of your eye (called aqueous humour). By reducing the amount of fluid produced, it reduces the pressure within your eye.
Before using levobunolol eye drops
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start using these drops it is important that your doctor or pharmacist knows:
- If you are pregnant or breast-feeding.
- If you have asthma or any other breathing problems.
- If you have heart problems.
- If you have Raynaud's disease or low blood pressure.
- If you have thyroid problems or diabetes.
- If you wear soft contact lenses.
- If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
- If you have ever had an allergic reaction to this or to any other medicine.
How to use levobunolol eye drops
- Wash your hands well before you use the drops.
- Remove the cap (or twist off the tip of the unit if you are using a single-dose unit).
- Tilt your head back a little and pull the lower lid of your eye out to form a pocket.
- Hold the bottle (or single-dose unit) upside down near to your eye. Try not to touch your eye as you do this.
- Apply enough pressure to release one drop into your eye.
- Close your eye for a minute or two, and press gently on the side of your nose where the corner of your eye meets your nose. This helps to stop the drop from draining away and keeps it in your eye.
- Repeat the process in your other eye if you have been told to use the drops in both eyes. (The contents of one single-dose unit are enough for both eyes.)
- Replace the cap (or if you are using the single-dose unit, throw it away).
Getting the most from your treatment
- Before you start using these eye drops, read the manufacturer's printed information leaflet from the pack. The leaflet will give you more information about the eye drops and a full list of possible side-effects from using them.
- Use one drop into the eye (or eyes) affected. Your doctor will have told you whether to use the drops once or twice a day - your dose will also be on the label of your pack. Remember to use these drops at regular intervals and try not to miss any doses.
- If you forget to use the drops, put them in as soon as you remember unless it is nearly time for your next dose, in which case just use the drops when they are next due. Do not double up to make up for a missed dose.
- Take care not to touch the tip of the dropper (or dose unit) with your eye, fingers, or any other surface. This is to prevent the drops from becoming contaminated.
- If you are using any other eye drops, leave 5-10 minutes between applying each one.
- When first put in, eye drops may sometimes cause blurred vision. If this happens, it should quickly clear. Make sure you can see clearly before you drive, or use tools or machines.
- Do not wear soft contact lenses if you are using eye drops from a bottle unless your doctor has advised you otherwise. This is because there is a preservative in bottles of eye drops which can affect soft contact lenses. You may wear soft contact lenses while you are using the single-dose units as there is no preservative in these.
- Keep your regular appointments with your doctor so that your progress can be checked.
- If you are having an operation or any dental treatment, remember to tell the person carrying out the treatment that you are using levobunolol eye drops.
Can levobunolol eye drops cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. These usually improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following side-effects continue or become troublesome.
|Common levobunolol eye drop side-effects||What can I do if I experience this?|
|Eye irritation or inflammation, redness||If any of these continue or become troublesome, speak with your doctor|
Important: if you experience any of the following, contact your doctor for advice straightaway:
- Any difficulties breathing, such as wheezing or shortness of breath.
- A skin rash.
If you experience any other symptoms which you think may be due to these eye drops, discuss them with your doctor or pharmacist.
How to store levobunolol eye drops
- Keep all medicines out of the reach and sight of children.
- Store in a cool, dry place, away from direct heat and light.
- Single-dose units should be used immediately the unit is opened. Do not store or re-use opened units for later doses. This is because the units do not contain any preservative.
- Eye drops only keep for four weeks once the bottle has been opened, so do not use the drops if the bottle has been open for longer than this. This will help to prevent the risk of eye infections.
