Benzodiazepines are prescribed to treat many conditions including severe anxiety, alcohol withdrawal symptoms and muscle spasms. Doctors usually prescribe them for a short time and only if other treatment isn't working.

What conditions are benzodiazepines used for?
Benzodiazepines have a calming, relaxing effect, and are used to treat a number of conditions, such as:
- severe anxiety, agitation or panic attacks if other treatments are not working
- severe insomnia (sleeping problems) if other treatments are not working
- to relax and/or sedate you during certain medical procedures or operations
- to reduce the symptoms of alcohol withdrawal if you have stopped drinking
- muscle spasms, to help relax your muscles
- epileptic fits (seizures) if a quick effect is needed.
Are benzodiazepines safe to take?
|Benzodiazepines can be highly addictive and should only be used for a short time.|
It is usually safe to take benzodiazepines as prescribed by your doctor. For anxiety and insomnia, it's best to use benzodiazepines for a short time only. Ongoing use for longer than 2–4 weeks is not recommended.
- Your body gets used to benzodiazepines quickly and after 2–4 weeks it's unlikely they will have the same effect.
- This doesn't happen if you take benzodiazepines every now and again, or for less than 2–4 weeks.
- If you take a benzodiazepine every day for longer than about 2–4 weeks, you may feel dependent on it. You may get withdrawal effects if you stop suddenly and the feelings of anxiety may be worse.
If you have been using benzodiazepines every day for a long time, your doctor could recommend you reduce your dose gradually when it is time to stop taking it. This is to reduce the risk of withdrawal effects.
