What exactly is chlordiazepoxide?

Chlordiazepoxide (Librium) is one of a group of medicines called benzodiazepine. They are also called
anxiolytics, or minor tranquillisers. It has many uses. For example:

  • for epilepsy
  • to reduce symptoms of anxiety and insomnia
  • to help people come off alcohol


Are they addictive?

Whilst less addictive than some other drugs, they are addictive and should only be given as a short course. For this reason, they will not be prescribed for more than two weeks.

Why have I been prescribed chlordiazepoxide?

If you stop drinking alcohol after a time of drinking too much you may get withdrawal effects. These effects can be very uncomfortable. In extreme cases they can be dangerous if they lead to DTs (delirium tremens). Withdrawal effects include:

  • shakes
  • sweating
  • having fits
  • seeing things that are not there (hallucinations)
  • feeling anxious and low in mood
  • feeling wound up and have difficulty in sleeping

Chlordiazepoxide can control these effects until your body is free of alcohol and has settled down. This usually takes 3 to 7 days from the time you stop drinking.

Is it safe to take?

It is safe to take for a short period of time, but does not suit everyone. Below are a few conditions for which it may be less suitable. If any of these apply to you please tell the nurse or your GP.

  • depression
  • breathing problems
  • liver or kidney trouble
  • if you take medicines or drugs on prescription or bought from a pharmacy
  • if you use illegal drugs bought on the street
  • If you are pregnant or breast feeding

What is the usual dose?

  • the dose you are given will depend on your individual assessment
  • you will usually be started on 15 to 30mg, 4 times a day
  • you may also receive a couple of extra doses in the first day or two
  • after this time the dose will be cut gradually every 1 to 2 days
  • a nurse will check your symptoms every day and will decide on any changes to the dose you take
  • you have agreed to take a regular alcohol breathalyser test

How should I take it?

  • most medicines now have an information leaflet for you to read
  • follow the instructions on the label carefully
  • never change the dose yourself
  • the dose should be taken every 4 to 6 hours over the day
  • Always take your medicine with a full glass of water.
If you have any questions speak to the nurse, your GP or pharmacist.
