Librium belongs to a group of medicines known as benzodiazepines,
which are tranquillisers (medicines that have a calming effect).
Librium capsules are used for the short-term treatment of severe
anxiety, which may occur alone or in association with sleeplessness
(insomnia) or personality/behavioural disorders. Librium capsules
may also be used to treat muscle spasms, and to relieve symptoms of
sudden alcohol withdrawal.

Taking other medicines
Tell your doctor or pharmacist if you are taking or have recently
taken any other medicines, including medicines obtained without a
prescription. This is extremely important, as using more than one
medicine at the same time can strengthen or weaken the effect of the
medicines involved. In particular, tell your doctor if you are taking
any of the following medicines:
Antidepressants, sleeping pills, other tranquillisers or other such
medicines which act on the brain and nerves.
Medicines used to relieve pain or anaesthetics.

Medicines for treating epilepsy (e.g. phenytoin
and phenobarbital).
Medicines that affect the liver (e.g. the antibiotic
rifampicin and cimetidine, a medicine used to
treat stomach problems).
Medicines used to treat viral infections (e.g.
ritonavir) as these medicines can potentiate the
actions of benzodiazepines.

Alcohol will increase the effects of the capsules and this can be

Librium Capsules are not for use in children.
You will normally see an improvement in your symptoms after 10 to
15 days of taking Librium regularly.

is because Librium Capsules may become less effective if you take
them for more than four weeks. If you think that your medicine is no
longer working, you should consult your doctor.
Also, you may become dependent on the capsules if you use them at
high doses and for long periods. Therefore, Librium Capsules are not
suitable for long-term use and after a few weeks it is worth trying to
get by without these capsules. This will help to prevent you becoming
used to Librium and reduce the risk of dependence.
