Cequa - Why is vial more than 2 drops?

How should I use Cequa?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Use the medicine about every 12 hours. Remove contact lenses first.

Wash your hands before using eye medication.

To apply the eye drops: Tilt your head back slightly and pull down your lower eyelid to create a small pocket. Hold the dropper above the eye and squeeze a drop into this pocket. Close your eyes for 1 or 2 minutes.

Turn the Restasis bottle upside down a few times to gently mix the medicine before each use.

Use only the number of drops your doctor has prescribed.

Wait at least 15 minutes before inserting contact lenses or using artificial tears.

Do not touch the tip of the eye dropper or place it directly on your eye. A contaminated dropper can infect your eye, which could lead to serious vision problems.

Cequa eye drops should be clear and colorless. Restasis eye drops should appear white in color.

Each single-use bottle is for one use only (in both eyes). Throw the bottle away after one use, even if there is still medicine left inside.

Store at room temperature. Store Cequa single-use vials in their original foil pouch.
