3. How to use Ketotifeno Dermogen

Follow the administration instructions for this medication exactly as indicated by your doctor or pharmacist. If in doubt, consult your doctor or pharmacist again.

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

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 your 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 your 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 6-8 with the other eye.
  9. Discard the container after use.
