  • Keep this leaflet, as you may need to read it again.
  • If you have any questions, ask your doctor, pharmacist, or nurse.
  • This medicine has been prescribed to you only, and you should not give it to others, even if they have the same symptoms as you, as it may harm them.
  • If you experience side effects, consult your doctor, pharmacist, or nurse, even if they are not listed in this leaflet. See section 4.

Contents of the leaflet:

  1. What is Zaditen and what is it used for
  2. What you need to know before using Zaditen
  3. How to use Zaditen
  4. Possible side effects
  5. Storage of Zaditen
  6. Package contents and additional information

1. What is Zaditen and what is it used for

Zaditen contains the active substance ketotifen, which is an antiallergic substance. Zaditen is used to treat the ocular symptoms of seasonal allergic conjunctivitis.

You should consult a doctor if it worsens or does not improve.

2. What you need to know before using Zaditen

Do not use Zaditen

If you are allergic to ketotifen or any of the other components of this medicine (listed in section 6).

Warnings and precautions

Consult your doctor, pharmacist, or nurse before starting to use Zaditen.

Using Zaditen with other medicines

If you need to apply any other eye medicine in addition to Zaditen, wait at least 5 minutes between the application of each product.

Tell your doctor or pharmacist if you are using or have recently used or may need to use any other medicine. This is especially important in the case of medicines used to treat:

  • depression, anxiety, and sleep disorders
  • allergies (e.g., antihistamines)

Using Zaditen with food, drinks, and alcohol

Zaditen may increase the effects of alcohol.

Pregnancy and breastfeeding

If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Zaditen can be used during breastfeeding.

Driving and using machines

Zaditen may cause blurred vision or drowsiness. Do not drive or use machines until these effects have disappeared.

3. How to use Zaditen

Follow exactly the administration instructions of this medicine indicated by your doctor or pharmacist. In case of doubt, consult your doctor or pharmacist again.

The recommended dose for adults, elderly, and children (3 years or older) is one drop in the affected eye(s) twice a day (morning and evening).

A single-dose container contains enough solution to treat both eyes in one application.

Instructions for use

  1. Wash your hands.
  2. Open the blister pack and remove the block of single-dose containers.
  3. Separate a single-dose container from the strip (Fig. 1).
  4. Store the remaining single-dose containers back in the blister pack and close the blister pack by folding the edge. Store the blister pack in the carton.
  5. Open the single-dose container by twisting the top. After opening, do not touch the tip of the dropper (Fig. 2).
  6. Tilt your head back (Fig. 3).
  7. Pull the lower eyelid down with your finger and hold the container with the other hand. Squeeze the container so that one drop falls into the eye (Fig. 4).
  8. Close your eyes and press the inner corner of the eye with the tip of your finger for 1-2 minutes. This prevents the drop from flowing down the tear duct into the throat, and most of the drop will remain in the eye (Fig. 5). If necessary, repeat steps 6 to 8 with the other eye.
  9. Discard the container after use.
