Wash your hands before using the eye drops.

To apply the eye drops:
Tilt your head back slightly and pull down your lower eyelid. Hold
the dropper above the eye with the dropper tip down. Look up and away from the dropper as
you squeeze out a drop, then close your eye.

use more than one drop in the same eye, wait about 5 minutes before putting in the next drop.
Do not allow the dropper tip to touch any surface, including
the eyes or hands. If the dropper becomes contaminated it could cause an infection in your eye,
which can lead to vision loss or serious damage to the eye.
Do not use the eye drops if the liquid has changed colors or has particles in
it. Call your doctor for a new prescription.
