3. How to use Zaditen
Follow exactly the administration instructions of this medicine given by your doctor or pharmacist. If you are unsure, consult your doctor or pharmacist again if you have any doubts.
The recommended dose in adults, the elderly, and children (3 years or older) is one drop in the affected eye(s) twice a day (morning and evening).
Instructions for use
- Wash your hands.
- Open the bottle. Do not touch the tip of the dropper after opening the bottle.
- Tilt your head back (Fig. 1).
- Pull the lower eyelid down with your finger and hold the bottle with the other hand. Squeeze the bottle so that one drop falls into the eye (Fig. 2).
- Close your eyes and press the inner corner of the eye with the tip of one finger for 1-2 minutes. This prevents the drop from flowing down the tear duct to the throat, and most of the drop will remain in the eye (Fig. 3). If necessary, repeat steps 3 to 5 with the other eye.
- Close the bottle after use.
