Proper use of Ilotycin

To use:

  • First, wash your hands. Tilt the head back and, pressing your finger gently on the skin just beneath the lower eyelid, pull the lower eyelid away from the eye to make a space. Squeeze a thin strip of ointment into this space. A 1-cm (approximately 1/3-inch) strip of ointment is usually enough, unless you have been told by your doctor to use a different amount. Let go of the eyelid and gently close the eyes. Keep the eyes closed for 1 or 2 minutes to allow the medicine to come into contact with the infection.
  • To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). After using erythromycin eye ointment, wipe the tip of the ointment tube with a clean tissue and keep the tube tightly closed.

To help clear up your infection completely, keep using this medicine for the full time of treatment, even if your symptoms begin to clear up after a few days. If you stop using this medicine too soon, your symptoms may return. Do not miss any doses.
