1. WHAT LIBRIUM IS AND WHAT IT IS USED FOR
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.
You must talk to a doctor if you do not feel better or if you feel worse.

Do not take Librium:
– If you are allergic to chlordiazepoxide or any of the ingredients of
this medicine (listed in section 6).
– If you are allergic (hypersensitive) to any medicine known as a
benzodiazepine (e. g. nitrazepam, diazepam, flurazepam, or temazepam).
– If you suffer from lung disease.
– If you suffer with breathing difficulties while awake or asleep.
– If you suffer from myasthenia gravis (a condition in which the
muscles become weak and tire easily).

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.
Children and adolescents
Librium Capsules are not to be used in anyone under 18 years of age.
Other medicines and Librium
Tell your doctor or pharmacist if you are taking, have recently taken
or might take any other medicines. 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, tranquilisers (may increase effects of relaxing muscles – higher risk of
falling in elderly patients) or other such medicines which act on the
brain and nerves.
– Medicines used to relieve pain or anaesthetics.
– Antihistamines (used for treating allergies) that cause drowsiness
– Medicines for treating epilepsy (e.g. phenytoin and phenobarbital).
– Medicines that affect the liver (e.g. the antibiotic rifampicin and cimetidine, omeprazole, macrolide antibiotics (erythromycin); 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.
– Drugs to treat high blood pressure (e.g. beta
blockers, anticoagulants, cardiac glycosides,
– Drugs known as dopaminergics (e.g. levodopa,
for Parkinson’s disease).
– Sodium oxybate used in patients with narcolepsy
(possible increase of respiratory depression)
– Theophylline; drug to make breathing easier

3. HOW TO TAKE LIBRIUM CAPSULES
Always take this medicine exactly as your doctor or pharmacist has
told you. Check with your doctor or pharmacist if you are not sure.
Your doctor will find the lowest dose to control your symptoms. The
dose that your doctor prescribes will depend on the nature of your
illness, your reaction to the medicine, your age and bodyweight.
If you think that the effect of your medicine is too weak or too strong,
talk to your doctor.
For the treatment of:
Up to 30 mg per day. The maximum
dose is 100 mg per day, taken in
divided doses throughout the day
associated with anxiety
10 to 30 mg before going to sleep.
Symptoms of sudden
25 to 100 mg. This can be repeated 2 to
4 hours after the initial dose, if necessary
10 to 30 mg per day, taken in divided
doses throughout the day.
If you are elderly or suffer from a lung, liver or kidney condition, or
are generally unwell, your doctor will usually prescribe a lower dose.
Use in children and adolescents
Librium Capsules are not to be used in anyone under 18 years of age.
Swallow the capsule(s) whole with a glass of water.
You will normally see an improvement in your symptoms after 10 to
15 days of taking Librium regularly.
Treatment will not normally be continued for more than 4 weeks. This
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.
Do not stop taking Librium Capsules without discussing with your
doctor (refer to “If you stop taking Librium” below.)
If you take more Librium than you should
If you take too many capsules or someone else accidentally takes your
medicine, contact your doctor, pharmacist or nearest hospital straight
If you forget to take Librium
Do not take a double dose to make up for a forgotten dose. Instead
you should simply continue with the next dose when it is due.
If you stop taking Librium
Your doctor will advise you when to stop taking the capsules. Do not
stop taking Librium Capsules abruptly. You may experience withdrawal effects if your treatment is stopped suddenly. This is less likely
if your dose is gradually reduced towards the end of your treatment.
Withdrawal symptoms may include:
– A recurrence of sleep problems
– Extreme anxiety
– Muscle pain
In severe cases the following symptoms may occur:
– changes in behaviour or the way you are feeling
– numbness and tingling of the extremities
– over-sensitivity to light, noise and touch
If you are woken up soon after taking the medicine your memory may
be temporarily affected.
If you have taken benzodiazepines for a long time, the reduction in
your dosage will be over a longer period of time than would normally
be required when you stop taking this medicine. You may need
additional help. Your doctor will be able to discuss this with you.
If you have any further questions on the use of this medicine, ask your
doctor or pharmacist.
