Opicapone may also be used for purposes not listed in this medication guide.

## Warnings

Opicapone is usually taken at bedtime, on an empty stomach.

Do not eat for at least 1 hour before or 1 hour after taking opicapone.

Your blood pressure may need to be checked often.

Opicapone may cause you to fall asleep during normal daytime activities such as working, talking, eating, or driving. You may fall asleep suddenly, even after feeling alert. Tell your doctor if you have any problems with daytime sleepiness or drowsiness.

Do not change your doses or stop using any of your medicines without your doctor's advice. Tell your doctor if any of your medicines seem to stop working.
