1. What Opticrom Hayfever is and what it is used for

Opticrom Hayfever 2% w/v Eye Drops (called Opticrom Hayfever in this leaflet) contain a medicine called sodium cromoglicate. This belongs to a group of medicines called anti-allergics.

It works by stopping the release of the natural substances in your eyes that can lead to an allergic reaction. Signs of an allergic reaction include itchy, watery, red or inflamed eyes and puffy eyelids.

These symptoms occur usually in the late spring or early summer when pollen from grasses or trees comes into contact with the eyes of people who are sensitive to them. This condition is sometimes called ‘hayfever eyes’ or by its medical term: seasonal allergic conjunctivitis.

2. Before you use Opticrom Hayfever

Do not use this medicine:

  • If you or your child are allergic (hypersensitive) to sodium cromoglicate, or any of the other ingredients of Opticrom Hayfever (listed in Section 6: Further information)
    Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, 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 Opticrom Hayfever.

Take special care with Opticrom Hayfever:

  • 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 is 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, e.g. 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 Opticrom Hayfever.
