## How should I use Besivance?

Use Besivance eye drops exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

To apply Besivance eye drops:

- Turn the bottle upside down and shake it once before each use.

- Tilt your head back slightly and pull down your lower eyelid to create a small pocket. 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.

- Gently press your finger to the inside corner of the eye (near your nose) for about 1 minute to keep the liquid from draining into your tear duct.

- 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.

Use this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses can increase your risk of infection that is resistant to medication.
