What are Benzodiazepines?

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

Benzodiazepines are medications that may be prescribed for problems such as 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 be effective medications. However, there are risks, particularly if they’re not used properly, or are used regularly (e.g. daily) for more than a few weeks. 

What are the effects of Benzodiazepines?

Once swallowed, benzodiazepines usually take about half an hour to start taking effect. The length of time the effects last for varies. 

The effects of benzodiazepines can be immediate or long-term, as listed in the table below.
