About carteolol eye drops

Type of medicine Beta-blocker
Used for Chronic open angle glaucoma
Also called Teoptic®
Available as 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. Carteolol 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 carteolol 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 have myasthenia gravis (a condition causing muscle weakness).
  • 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 carteolol eye drops

  • Wash your hands well.
  • Remove the cap from the bottle.
  • Tilt your head back a little and pull the lower lid of your eye out to form a pocket.
  • Hold the bottle upside down near to your eye. Try not to touch your eye as you do this.
  • Apply enough pressure to the bottle 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 asked to use the drops in both eyes.
  • Replace the cap.

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, twice each day. Remember to use these drops at regular intervals and try not to miss any doses.
  • If you forget to use the drops, apply them 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 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 unless your doctor has advised you otherwise. This is because there is a preservative in these eye drops which can affect soft contact lenses.
  • 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 carteolol eye drops.

  • Keep all medicines out of the reach and sight of children.
