Patient leaflet - Librium 5 mg capsules

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 eff ect). 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.

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE LIBRIUM CAPSULES

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 benzodi-azepine (e. g. nitrazepam, diazepam, fl urazepam, or temazepam).
  • If you suff er from lung disease.
  • If you suff er with breathing diffi culties while awake or asleep.
  • If you suff er from myasthenia gravis (a condition in which the muscles become weak and tire easily).
  • If you are suff ering from a psychiatric illness or a personality disorder (severe mental problems).
  • If you have a severe liver condition.
  • If you have spinal or cerebral ataxia

Warnings and precautions

Talk to your doctor or pharmacist before taking Librium if:

  • You have a long-term lung, liver or kidney disease.
  • You suff er from depression or have recently suff ered the death of a close friend or relative.
  • You are suff ering or have suff ered from a mental illness.
  • You have abused alcohol or drugs.

  • You are pregnant or breast feeding.

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 conse-quently 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. Th is is extremely important, as using more than one medicine at the same time can strengthen or weaken the eff ect 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 eff ects 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 (e.g. chlorphenamine)
  • Medicines for treating epilepsy (e.g. phenytoin and phenobarbital).
  • Medicines that aff ect the liver (e.g. the antibiotic rifampicin and cimetidine, omeprazole, macrolide antibiotics (erythromycin); medicines used to treat stomach problems, disulfi ram 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, moxonidine).

    • Drugs known as dopaminergics (e.g. levodopa, for

      Parkinson’s disease).

    • Sodium oxybate used in patients with narcolepsy

      (possible increase of respiratory depression)

    • Th eophylline; drug to make breathing easier

Concomitant use of Librium Capsules and opioids

(strong pain killers, medicines for substitution thera-

py and some cough medicines) increases the risk of

drowsiness, diffi culties in breathing (respiratory de-

pression), coma and may be life-threatening. Because of

this, concomitant use should only be considered when other treatment op-tions are not possible.

However if your doctor does prescribe Librium Capsules together with opi-oids the dose and duration of concomitant treatment should be limited by your doctor.

Please tell your doctor about all opioid medicines you are taking, and fol-low your doctor’s dose recommendation closely.
