Clinical author's note Michael Stewart 19/2/2020: Rapitil® eye drops were discontinued in the UK in April 2018. At the time of review there are no branded or generic eye drop products containing nedocromil available in the UK. Nedocromil eye drops may still be available in other countries. This medicine leaflet is based on medical information available in the UK at the time of writing and is left here for reference purposes. Please also refer to the manufacturer's information supplied with your medicine.
Nedocromil sodium eye drops help to prevent red, watery, itchy eyes caused by allergies.
The drops are usually used twice a day. If your symptoms are more severe, your doctor may suggest you use them three or four times daily.
When first put in, eye drops can cause blurred vision. Wait until this clears before you drive or before you use tools or machines.

About nedocromil sodium eye drops
Type de médicament | Anti-allergic eye drops |
Utilisé pour | To relieve the symptoms of allergic conjunctivitis |
Aussi appelé | Alocril® (in US); Rapitil® (discontinued) |
Disponible sous forme de | Gouttes pour les yeux |
Conjonctivite allergique causes red, watery, itchy eyes. It is caused by exposure to irritants such as plant pollens, pet fur, cosmetics or house dust mite. Seasonal allergic conjunctivitis occurs at certain times in a year, a common cause being an allergy to pollen in the rhume des foins season. Perennial allergic conjunctivitis persists throughout the year. This is commonly due to an allergy to house dust mite or animal hair.
Nedocromil sodium eye drops can help prevent the symptoms of allergic conjunctivitis. The drops work by stopping the release of certain natural substances which can lead to an allergic reaction in your eyes. The drops can be prescribed for adults and for older children.

How to use nedocromil sodium eye drops
Retour au sommaireLavez-vous les mains avant d'utiliser les gouttes.
Retirez le bouchon.
Tilt your head back a little and then pull the lower lid of your eye downwards to form a pocket between the eye and the lower eyelid.
Tenez la bouteille à l'envers près de votre œil. Essayez de ne pas toucher votre œil en faisant cela.
Apply sufficient pressure to the bottle to release one drop into your eye. Only use a second drop if the first drop missed going into your eye.
Fermez votre œil pendant une minute ou deux, et appuyez doucement sur le côté de votre nez où le coin de votre œil rencontre votre nez. Cela aide à empêcher la goutte de s'écouler et la maintient dans votre œil.
Repeat the process in your other eye.
Remettez le bouchon.
Tirer le meilleur parti de votre traitement
Retour au sommaireBefore you start using the eye drops, read the manufacturer's printed information leaflet from the pack. It will give you more information about the drops, and it will also provide you with a full list of the side-effects which you could experience from using them.
Please follow the directions your doctor gives to you for using the eye drops. You could be asked to use the drops two, three or four times a day. Put one drop into both eyes for each dose. Try to use the drops at regular intervals throughout the day, 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.
Faites attention à ne pas toucher votre œil, vos doigts ou toute autre surface avec le compte-gouttes du flacon. Cela pourrait contaminer les gouttes restantes dans le flacon.
When you first put the drop into your eye, it may cause blurred vision. This should quickly clear, but make sure you can see clearly again before you drive, or before you use machines or tools.
If you are using any other eye drops, leave 5-10 minutes between using the other eye drops. 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.
If your symptoms do not start to improve within a few days, or if they become worse, make another appointment to see a doctor.
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 can affect soft contact lenses.

Common nedocromil sodium side-effects (these affect fewer than 1 in 10 people) | Que puis-je faire si je ressens cela ? |
Mild eye irritation such as burning or stinging, blurred vision | These usually disappear within a few minutes of applying the eye drops. Do not drive and do not use tools or machines until your vision is clear again |

Occasionally people can be allergic to eye drops, particularly when the eye drops contain a preservative. If you notice a rash around your eyes, or any swelling or increased itching, stop using the drops and contact a doctor for advice. If you experience any other symptoms which you think may be due to the eye drops, speak with your doctor or pharmacist for further advice.
