IMPORTANT INFORMATION

Darkening of your eyes and lashes

This drug can darken the color of your eye or change it from a light color to brown. It can also cause the skin around your eye to darken. It may cause your eyelashes to grow longer, thicker, and darker in color. These changes often occur slowly, but they can be permanent. If you only use this drug in one eye, your eyes may look different from each other. Call your doctor if you have these changes.

Contact lenses

If you wear contact lenses, you should remove them from your eyes before using this drug. Wait at least 15 minutes after using your eye drops before you put your contacts in your eyes again.

Contamination of dropper tip and solution

Be careful not to let the dropper tip of the eye drops touch your eye, eyelids, or surrounding areas when giving yourself the medication. This could contaminate the dropper tip and the solution.

Eye problems

This drug may cause macular edema. In this condition, fluid builds up in your eye and causes it to swell. This can damage your vision. You’re at higher risk for this side effect if you have a history of macular edema or other eye problems. Talk to your doctor before using latanoprost if you have a history of eye problems.

Latanoprost comes with serious risks if you don’t take it as prescribed.

If you stop taking the drug or don’t take it at all

If you miss doses or don’t take the drug on schedule

Your medication may not work as well or may stop working completely. For this drug to work well, a certain amount needs to be in your body at all times.

If you take too much

If you take too much, you could also have dangerous levels of the drug in your body. Symptoms may include:

  • eye irritation
  • redness

If you think you’ve taken too much of this drug, call your doctor or local poison control center. If your symptoms are severe, call 9-1-1 or go to the nearest emergency room right away.
