Side Effects
(This is a list of the most common side effects; for a complete list, see the insert provided with your medication)

The most frequent side effects are temporary stinging and burning and blurred vision upon instillation. Some patients also have a slight redness of the eye upon waking in the morning. This is normal, and usually clears up after a couple of hours. In patients with a hazel-colored iris, there is a 15% chance of darkening of the iris. If this occurs, the eye color changes from hazel to brown. This only occurs in certain eyes. Ask your doctor if you are at risk for this change in eye color. Other side effects can include growth of the eye lashes, darkening of the skin around the eyes, and inflammation inside the eyes.

Some patients develop flu-like symptoms, skin rash, or muscle and joint pains.

Special Precautions
If you notice a persistent change or worsening of your vision, especially if you have had prior eye surgery, notify your doctor immediately.

You must keep your regularly scheduled appointment with your eye doctor so the effect of this medicine can be monitored. All medicines should be taken exactly as prescribed. If you experience any problems with this medication, call your doctor immediately.
