3. How to use Ketobrill

Follow exactly the administration instructions of this medicine given by your doctor. Ask your doctor or pharmacist if you have any doubts.

The recommended dose in adults, elderly and children (from 3 years onwards) is one drop in the affected eye(s) twice daily (in the morning and at night).

Use in children under 3 years

Safety and efficacy in children under 3 years have not been established.

A single-dose container contains a sufficient amount of solution to treat both eyes in one application.

Instructions for use

  1. Wash your hands.
  2. Open the aluminum bag and take out a strip of single-dose containers.
  3. Separate one single-dose container from the strip (Fig. 1).
  4. Put the remaining single-dose containers back in the aluminum bag and fold the edge of the bag. Keep the bag in the box.
  5. Open the single-dose container by twisting the top end. After opening the container, 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 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 stays in the eye (Fig. 5). If necessary, repeat steps 6 to 8 in the other eye.
