Dosing—

The dose of this medicine will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of this medicine. If your dose is different, do not change it unless your doctor tells you to do so.

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. Drop the medicine into this space. Let go of the eyelid and gently close the eyes. Do not blink. Keep the eyes closed and apply pressure to the inner corner of the eye with your finger for 2 or 3 minutes to allow the medicine to be absorbed by the eye. This is especially important in infants.
  • Immediately after using the eye drops, wash your hands to remove any medicine that may be on the hand to keep the medicine applicator tip as germ-free as possible. If you are using the eye drops for an infant or child, be sure to wash the infant's or child's hands also, and do not let any of the medicine get in the infant's or child's mouth.
  • To keep the medicine as germ-free as possible, do not touch the applicator tip to any surface (including the eye). Also, keep the container tightly closed.
