6. Further information
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.
Do not take Librium if you:

ingredients of Librium Capsules (these are listed in section 6,
“Further Information”).

diazepine (e.g. nitrazepam, diazepam, flurazepam, or temazepam).
■ suffer from lung disease.
■ suffer with breathing difficulties while awake or asleep.
■ suffer from myasthenia gravis (a condition in which the muscles
become weak and tire easily).
■ are suffering from a psychiatric illness or a personality disorder
(severe mental problems).

Librium capsules relax the muscles, therefore elderly patients should
take extra care when they get up at night as there is a risk of falls and
consequently of injuries including hip fractures.
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 tablets, neuroleptics, hypnotics, tranquillisers or other such medicines which act on the brain and
■ Medicines used to relieve pain or anaesthetics.
■ Antihistamines (used for treating allergies) that cause drowsiness
(e.g. chlorphenamine).
■ Medicines for treating epilepsy (e.g. phenytoin and phenobarbital).
■ Medicines that affect the liver (e.g. the antibiotic rifampicin and
cimetidine, omeprazole; medicines used to treat stomach problems,
disulfiram and contraceptive agents).
■ Medicines used to treat viral infections (e.g. ritonavir) as these
medicines can potentiate the actions of benzodiazepines.

blockers, anticoagulants, cardiac glycosides,

15 days of taking Librium regularly.

longer working, you should consult your doctor.

high doses and for long periods. Therefore, Librium Capsules are not
