How Does It Work?

Halcion is part of a group of medicines called benzodiazepines. Benzodiazepines have several effects on the body, including:
  • Reducing anxiety
  • Causing sleepiness
  • Relaxing muscles
  • Stopping seizures
  • Impairing short-term memory.
All of the medicines in this category can have these effects to some degree, depending on the specific benzodiazepine that is being taken. They work in the brain by enhancing the effects of gamma-aminobutyric acid (GABA), a brain chemical that has a naturally calming effect. GABA can slow down or stop certain nerve signals in the brain. This is why Halcion and other benzodiazepines are known as mild tranquilizers, sedatives, or central nervous system depressants (CNS depressants).
