Nedocromil sodium drops are used to treat red, watery, itchy eyes caused by allergies such as hay fever.

They are usually used twice a day. If your symptoms are severe, your doctor may suggest you use them up to four times daily.

When first put in, eye drops may cause blurred vision. Wait until this clears before you drive.

The drops are not suitable for children under 6 years of age.

Available asEye drops

Allergic conjunctivitis causes red, watery, itchy eyes. A common cause is an allergy to pollen in the hay fever season. Other causes are less common such as allergies to house dust mite, cosmetics, and problems with contact lenses. Nedocromil sodium eye drops relieve the symptoms of allergic conjunctivitis by reducing the amount being released of some chemicals which cause inflammation.

To make sure this is the right treatment for you, before you start using nedocromil sodium eye drops it is important that your doctor knows:

  • If you wear soft contact lenses.
  • If you are pregnant or breast-feeding.
  • If you have ever had an allergic reaction to any eye drops.
  1. First wash your hands.
  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. Apply enough pressure 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.
  8. Replace the cap.
  • Before using the eye drops, read the manufacturer's printed information leaflet supplied with the drops. The manufacturer's leaflet will give you more information about nedocromil sodium and a full list of the side-effects which you may experience from using the eye drops.
  • Use the drops two to four times each day into both eyes, as directed by your doctor. Try to use the drops at regular intervals and try not to miss any doses. If you are using the drops for hay fever, do not use them continually for more than three months.
  • Take care not to touch your eye, fingers, or any other surface with the dropper of the bottle. This could contaminate the drops left in the bottle.
  • When first put in, eye drops can cause blurred vision. This should quickly clear, but make sure you can see properly before you drive, use machines or do any other jobs which would be dangerous if you were unable to see clearly.
  • If your symptoms do not start to improve within a few days, or if they become worse, check again with your doctor.
  • If you are using any other eye drops or ointments, leave 5-10 minutes between using each one.
  • Do not wear soft contact lenses while you are using nedocromil sodium eye drops unless your doctor has advised you otherwise. This is because there is a preservative in bottles of eye drops which may affect soft contact lenses.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with nedocromil sodium eye drops. You will find a full list in the manufacturer's information leaflet supplied with your drops. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Common nedocromil sodium side-effectsWhat can I do if I experience this?
Mild eye irritation such as burning or stinging, blurred visionThese usually disappear within a few minutes of applying the eye drops. Do not drive or use tools or machines until your vision is clear
An unusual taste in your mouthAfter using the drops, make sure you press gently on the side of your nose where the corner of your eye meets your nose. Try having a soft drink to take the taste away

If you experience any other symptoms which you think may be due to the eye drops, speak with your doctor or pharmacist for advice.

  • Keep all medicines out of the reach and sight of children.
  • Store in a cool, dry place, away from direct heat and light.
  • Eye drops only keep for four weeks once the bottle has been opened so throw away the bottle after this time, even if there is some solution left. Never keep opened bottles of eye drops to use later. This will help prevent the risk of eye infections.

This medicine is for you. Never give it to other people even if their condition appears to be the same as yours.

Make sure that the person prescribing this medicine knows about any other medicines that you are using. This includes medicines you buy and herbal and homeopathic medicines.

If you suspect that someone has swallowed some of this medicine, go to the accident and emergency department of your local hospital. Take the container with you, even if it is empty.

If you are having an operation or dental treatment, tell the person carrying out the treatment which medicines you are using.
