When to use it

Use Zaditen Eye Drops at about the same time every day unless your doctor or pharmacist tells you otherwise.

Using your eye drops at the same time each day will have the best effect in treating your allergic conjunctivitis. It will also help you remember when to use the eye drops.

How long to use it

You can stop using this medicine when the itching in your eye(s) has gone.

If you forget to use it

If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to.

Otherwise, use the drops as soon as you remember, and then go back to using your medicine as you would normally.

Do not use double the amount to make up for the dose that you missed. Using multiple doses may cause unwanted side effects.

If you are not sure what to do, ask your pharmacist or doctor.

If you use too much (overdose)

It is unlikely that you will experience symptoms or side effects if you accidently swallow Zaditen. Similarly, do not be concerned if more than one drop is accidently dropped into your eye.

If you have any doubts, speak to your doctor or pharmacist for advice or contact the Poisons Information Centre on 13 11 26.

After using Zaditen

Storage

Keep your eye drops in a cool place where the temperature stays below 25°C. Do not freeze the eye drops.

Do not store Zaditen Eye Drops or any other medicine in the car, bathroom, the window sill or in other warm, damp places. Heat and dampness can destroy some medicines.

Keep it out of the sight or reach of children. A locked cupboard at least one and a half metres above the ground is a good place to store medicines.

Multi-dose Bottle:

  • Keep the bottle sealed until it is time to use the eye drops.
  • After opening, write the date on the bottle.
  • Use the eye drops for four (4) weeks.
    These eye drops contain a preservative which helps prevent germs growing in the solution for the first four weeks after opening the bottle. After this time there is a greater risk that the drops may become contaminated and cause an eye infection.
    If you need to continue treatment get a new bottle of drops, even if there is some left in the old bottle.
  • Put the top back on the bottle right away after use to avoid contaminating the eye drops. Do not leave the top off the bottle for any length of time as the drops may not keep well.

Single Dose Units:

  • Keep the inner blisters sealed until it is time to use the eye drops.
    If you open the inner blisters, the eye drops may not keep well.
  • After opening the single dose unit, use the drops once and immediately discard any unused solution.
    These eye drops contain no preservative.
  • Keep the remaining single dose units at room temperature (below 25°C), preferably in the carton.

Disposal

If your doctor tells you to stop using the eye drops or they have passed their expiry date, ask your pharmacist what to do with any remaining solution.
