About apraclonidine eye drops

Type of medicine

An alpha2-adrenoceptor agonist eye drop

Used for

Treatment of glaucoma; and to control eye pressure during laser surgery

Also called


Available as

Eye drops (0.5%) and single-dose units (1%)

An increase in pressure within your eye can lead to damage to the optic nerve at the back of your eye. When this occurs it is called glaucoma. Glaucoma can lead to a loss of vision if it is not treated. Treatment with apraclonidine eye drops, in addition to your usual drops for glaucoma, can help to reduce eye pressure.

The 0.5% drops are prescribed for people who need additional help to control pressure in the eye in order to delay the need for laser treatment or surgery. The drops are usually prescribed for a short period of time, as the benefit from them tends to be lost after about a month, although this differs from person to person.

Apraclonidine is also used as a treatment during laser surgery. A higher-strength (1%) solution is used for this. It will be applied for you by the clinical staff who are treating you.

Apraclonidine eye drops are thought to work by reducing the amount of fluid (called aqueous humour) that you make in the front part of your eye. This helps to lower the pressure within your eye.

Before using apraclonidine eye drops

Some medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start using the eye drops, it is important that your doctor knows:

  • If you wear soft contact lenses.

  • If you have a heart condition or blood vessel disorder.

  • If you have a depressive illness.

  • If you have any of the following conditions: high blood pressure, Parkinson's disease, Raynaud's syndrome.

  • If you are pregnant or breastfeeding.

  • If you have any problems with the way your liver works, or any problems with the way your kidneys work.

  • If you have ever had an allergic reaction to a medicine.

  • If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

How to use apraclonidine eye drops

  1. Wash your hands well before you use the drops.

  2. Remove the cap.

  3. Tilt your head back a little and pull the lower lid of your eye downwards to form a pocket.

  4. Hold the bottle upside down near to your eye. Try not to touch your eye as you do this.

  5. Gently press on the base of the bottle to release one drop into your eye.

  6. 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.

  7. Repeat the process in your other eye if you have been told to use the drops in both eyes.

  8. Replace the cap.

Getting the most from your treatment

  • Before you start using the eye drops, read the manufacturer's printed information leaflet from the pack. It will give you more information about the eye drops and will provide you with a full list of the side-effects which you may experience from using them.

  • Use one drop into the eye (or eyes) affected three times each day. The benefit of treatment with the drops usually lasts for up to a month.

  • Remember to use the drops at regular intervals and try not to miss any doses. If you do forget, use 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.

  • As you will also be using other eye drops for glaucoma, you should leave 5-10 minutes between putting in each type of drop. This is to prevent more liquid going into your eye than it can handle. Otherwise the drops will overflow from your eye and not have the intended effect.

  • When first put in, eye drops can make your eyes water and may sometimes cause blurred vision. If this happens, it should quickly clear. Make sure you can see clearly again before you drive, or use tools or machines.

  • Do not wear soft contact lenses unless your doctor has advised you otherwise. This is because bottles of eye drops contain preservatives which can affect some soft contact lenses.

  • Please keep your regular appointments with your doctor and eye clinic so that your progress can be monitored.
