This medicine contains sodium cromoglicate which 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.

This medicine is used for the prevention, relief and treatment of eye allergies.

This includes:

  • Short and long term allergic conjunctivitis (inflammation of parts of the eye)
  • More severe cases of conjunctivitis (‘vernal keratoconjunctivitis’). Signs include bumps inside the upper eyelid, sensitivity to light and severe itching.
Do not use this medicine:
  • If you are allergic (hypersensitive) 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.

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.
