Patient Information Leaflet

Do not use this medicine:

• If you or your child are allergic to sodium cromoglicate or any of the other ingredients of this medicine. Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your ips, face, throat, tongue and worsening of redness, itching or swelling of the eye or eyelid.
• If your child is under 6 years of age.
• For other allergic eye symptoms (not caused by hayfever). Other things in everyday life can start allergies causing eye symptoms in certain people. For example contact with animals including pets, house dust mites, other particles and chemicals. Talk to your pharmacist or doctor.

Do not use this medicine if the above applies to you. If you are not sure, talk to your doctor or pharmacist before using these eye drops.

You must be confident that you or your child's irritated eyes are caused by hayfever, or have been previously diagnosed by your doctor to suffer from hayfever: You can be sure allergic eyes are caused by hayfever if:

• Both eyes are affected
• You also have a runny or blocked nose
• Your eyesight is not affected
• You know you suffer from hayfever and your symptoms coincide with the times of year when grass or tree pollen is high.

But if you or your child have:

• No nose symptoms
• Only one eye affected
• Your sight is affected.

Or if the eye symptoms:

• Occur at the wrong time of year for hayfever
• Are likely to be caused by another allergy, eg. a pet or dust mite allergy.

Then you cannot be sure that the condition is due to hayfever and you should see your doctor or pharmacist before you use these drops.

If you are not sure if the above applies to you, talk to your doctor or pharmacist before using this medicine.
