About nedocromil sodium eye drops
|Type of medicine||Anti-allergic eye drops|
|Used for||To relieve the symptoms of allergic conjunctivitis|
|Available as||Eye drops|
Allergic conjunctivitis 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 hay fever 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.
Before using nedocromil sodium eye drops
To make sure that 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.
How to use nedocromil sodium eye drops
- Wash your hands before you use the drops.
- Remove the cap.
- 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.
- Hold the bottle upside down near to your eye. Try not to touch your eye as you do this.
- 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.
- 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.
- 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 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.
- 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 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.
