What are Benzodiazepines?

Benzodiazepines are also known as benzos, sleeping tablets, downers, or sleeping pills.

Benzodiazepines are medications that may be prescribed for problems such insomnia (being unable to sleep) or anxiety. They are usually prescribed in a tablet or capsule form and the most common is diazepam (Valium). Others include alprazolam (Xanax), and oxazepam (Serepax). If used as prescribed by doctors, benzodiazepines can work well. However, there are risks, particularly if they’re not used properly, or are used regularly (e.g. daily) for more than a few weeks.
