Benzodiazepine Side Effects

Benzodiazepines, also known as “benzos,” are a class of prescription depressants that work in the body by depressing activity in the central nervous system.

When taken as prescribed, this can cause feelings of drowsiness, sedation, reduce anxiety, and slow down a person’s breathing. Unfortunately, these drugs are also sometimes misused.

Abusing benzodiazepines such as Xanax or Valium by taking them in ways other than prescribed can cause additional side effects, including:

• the rapid development of tolerance to benzodiazepines
• dependence
• cognitive decline
