Opticrom Allergy 2% w/v Eye Drops contains a medicine called sodium cromoglicate. It works by stopping the release of the natural substances in your eyes that can lead to an allergic reaction such as 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.


Do not use this medicine:

  • If you or your child are allergic to sodium cromoglicate or any of the other ingredients of this medicine (listed in Section 6). 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 these eye drops.


Please see the enclosed medicine leaflet for directions on use.
