Read this Medication Guide before you start taking HALCION and each time you get a refill. There may be new information. This Medication Guide does not take the place of talking to your doctor about your medical condition or treatment. You and your doctor should talk about the SEDATIVEHYPNOTIC when you start taking it and at regular checkups.

What is the most important information I should know about HALCION?

After taking a SEDATIVE-HYPNOTIC, you may get up out of bed while not being fully awake and do an activity that you do not know you are doing. The next morning, you may not remember that you did anything during the night. You have a higher chance for doing these activities if you drink alcohol or take other medicines that make you sleepy with a SEDATIVE-HYPNOTIC. Reported activities include:

  • driving a car (“sleep-driving”)
  • making and eating food
  • talking on the phone
  • having sex
  • sleep-walking


1. Take HALCION exactly as prescribed

  • Do not take more HALCION than prescribed.
  • Take HALCION right before you get in bed, not sooner.

2. Do not take HALCION if you:

  • drink alcohol
  • take other medicines that can make you sleepy. Talk to your doctor about all of your medicines. Your doctor will tell you if you can take HALCION with your other medicines
  • cannot get a full night's sleep
  • are pregnant or considering becoming pregnant

3 Call your doctor right away if you find out that you have done any of the above activities after taking HALCION.

HALCION is a federally controlled substance (C-IV) because it can be abused or lead to dependence. Keep HALCION in a safe place to prevent misuse and abuse.
