What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of flurazepam can be fatal if you take it with alcohol, opioid medicine, or other drugs that cause drowsiness or slow your breathing.

Overdose symptoms may include drowsiness, confusion, slurred speech, weak or shallow breathing, or coma.

You may still feel sleepy the morning after taking flurazepam. Wait until you are fully awake before you drive, operate machinery, or do anything that requires you to be awake and alert. Your reactions may be impaired.

Daytime drowsiness may last for several days after you stop taking flurazepam. Drowsiness can cause falls, accidents, or severe injuries.
