Ativan

Ativan is a drug that is approved to treat anxiety. The drug is thought to work in the brain by enhancing the effects of gamma-aminobutyric acid (GABA) -- a brain chemical that is naturally calming. Ativan comes in tablet, oral liquid, and injectable forms. As with all medications, side effects are possible during treatment with Ativan. Side effects of this drug can include dizziness, weakness, and unsteadiness.

How Does Ativan Work?

Ativan is part of a group of medicines called benzodiazepines. These medications have several effects on the body, including:
 
  • Reducing anxiety
  • Causing sleepiness
  • Relaxing muscles
  • Stopping seizures
  • Impairing short-term memory.
     
All 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 is naturally calming. GABA can slow down or stop certain nerve signals in the brain. This is why Ativan and other benzodiazepines are known as mild tranquilizers, sedatives, or central nervous system depressants (CNS depressants).
