What are benzodiazepines and “Z” drugs and what are they used for?

Benzodiazepines are a group of medicines which are sometimes used to treat anxiety e.g. diazepam, or insomnia (difficulty sleeping) e.g. temazepam or nitrazepam. The Z drugs (zopiclone and zolpidem) are other sleeping tablets that are similar to benzodiazepines.

These medicines can help ease symptoms of anxiety or aid sleep but are meant for short-term use, maximum 2-4 weeks.

Store these medicines safely. Only take them if they have been prescribed for you. Don’t share them with other people, even if their symptoms are the same. Obtaining or sharing benzodiazepines or Z drugs without a valid prescription is a criminal offence.

Illegal versions of benzodiazepines and Z drugs are also available via the internet or on ”the street”. The composition and quality of these is unknown and you should not buy or take these as they may harm you.

Why are doctors reluctant to prescribe these tablets?

Problems with Benzodiazepine and Z drugs:

Drowsiness and Clumsiness

They may affect how your muscles work or make you sleepy. Drowsiness may persist the following day. It is essential that you do not drive or use any tools or machines if you are affected in this way. Driving under the influence of these medicines is an offence. Take extra care if you get up during the night as there is a risk of falls and consequently injuries including hip fractures.

Memory Problems

They have been linked with memory problems such as Dementia and Alzheimer’s disease, particularly if used long-term.

Tolerance

If you take benzodiazepines or Z drugs regularly, the body becomes so used to them that they may loose their effectiveness and no longer help your original sleeping or anxiety problem. This is known as ‘tolerance’ and can develop within 3-14 days of continuous use.

Dependence

If you take a benzodiazepine or Z drug for a number of weeks or longer it is likely that you will experience withdrawal symptoms if you stop them suddenly. These may include:

· inability to sleep	· anxiety
· sweating	· panic attacks
· headache	· odd sensations
· tremor	· feelings of unreality
· feeling sick	· feeling awful
· palpitations	· hearing and visual disturbance
· muscle spasms

Taking with other substances

Do not drink alcohol while you are taking benzodiazepines or Z drugs. Taking some medicines along with benzodiazepines or Z drugs increases the risk of drowsiness, difficulties in breathing, coma and may be life-threatening. Examples of such medicines include:

Opioids (eg morphine, tramadol, co-codamol, oxycodone, fentanyl)
Epilepsy medicines
Medicines that affect the liver (e.g. the antibiotic rifampicin).
Moxonidine (for blood pressure),
Muscle relaxants (e.g. baclofen, tizanidine).

If the medication combination is essential, please follow your doctor’s dose recommendation closely and seek medical attention if you experience the symptoms listed.
