Benzodiazepines (pronounced BEN-ZOH-DIE-AZ-A-PINS) are depressant drugs. Benzodiazepines, also known as "minor tranquillisers", are prescribed by doctors to relieve stress and anxiety and to help people sleep. Some people use benzodiazepines illegally, to become intoxicated.
Like other depressants, benzodiazepines work by slowing down the activity of the central nervous system. In the short term, they can help with relaxation, calmness and relief from tension and anxiety. But they do not solve the problem that caused the anxiety in the first place and they can have a range of unwanted side effects.
Benzodiazepines usually come in the form of tablets and capsules, in a range of colors and designs. They are generally stamped with their name and milligram quantity.
Benzodiazepines are prescribed as sedatives/hypnotics (to induce sleep) or anxiolytics (to relieve anxiety). They vary in how quickly they work and how long they last. They are also used to treat epilepsy, to relax muscles, to help people withdraw from alcohol, or as an anaesthetic before surgery.
Some people use benzodiazepines illegally to become intoxicated. They may use them when they can't get heroin, when they are trying to get off heroin or to increase the effects of heroin. People who use stimulant drugs such as amphetamines (speed) or MDMA (ecstasy) may use benzodiazepines to help when they are "coming down" from a "high", and to help them sleep.
Benzodiazepines are known by their chemical (generic) names and their brand/trade names. In each case, these are exactly the same drug, usually made by different companies. There are over 24 different prescribed benzodiazepines, including:
|Chemical name||Brand names|
|Oxazepam||Alepam, Murelax, Serepax|
|Temazepam||Normison, Euhypnos, Temaze|
The unwanted negative effects of benzodiazepines vary according to dose.
The immediate effects of low to moderate doses include mild impairment of thought processes, memory and coordination; drowsiness, tiredness and lethargy; dizziness; vertigo; and blurred or double vision. The person may experience a dry mouth, slurred speech and stuttering, tremors, nausea and vomiting, loss of appetite, constipation or diarrhoea. Feelings of euphoria or isolation and emotional depression may also occur.
Higher doses can result in drowsiness, over-sedation and sleep. They may produce an effect similar to alcohol intoxication. Other effects can include confusion, slurred speech, poor coordination, impaired judgement, difficulty thinking clearly, loss of memory, blurred or double vision and/or dizziness. Mood swings and aggressive outbursts may also occur. The symptoms intensify as the dose increases. Feelings of jitteriness and excitability often become evident as the effects of large doses wear off.
Very high doses of benzodiazepines can cause respiratory depression, unconsciousness or coma. Death rarely occurs from overdose of benzodiazepines alone, but deaths can occur if large doses are combined with alcohol or other drugs. Deaths can also occur from inhalation of mucus or vomit when a person is unconscious.
A "binge" is when a large amount of benzodiazepines is taken in one session, rather than as prescibed by a doctor. There is a strong possibility of overdosing and that a high level of benzodiazepine will remain in the bloodstream the day after a binge. This makes it dangerous to drive or operate machinery. If the binges are fairly close together, there is a risk of developing dependency on the drug.
The use of benzodiazepines over a long period of time (more than two to three weeks) should be carefully monitored by your doctor. Some of the health effects of using high doses of benzodiazepines in the long term include:
|increased risk of accidents|
|increased risk of falling|
|confusion and diffculty thinking clearly|
|lethargy and lack of motivation|
|difficulty sleeping and disturbing dreams|
|personality change and changes in emotional responses|
|irritability, paranoia and aggression|
Injecting benzodiazepines can be very dangerous and can result in serious health problems. Most benzodiazepines are intended for oral use but some people inject them. Serious effects include:
|red, swollen, infected skin|
|amputation of limbs due to poor circulation|
|damage to organs|
|stroke, and even death.|
Sharing needles, syringes and other injecting equipment can greatly increase the risk of contracting blood-borne viruses such as hepatitis B, hepatitis C and HIV (human immunodeficiency virus—the virus that causes AIDS).
People who are physically dependent on benzodiazepines can develop tolerance to the drug. This can happen very quickly and means that more of the drug is required to get the same effect.
Dependence on benzodiazepines can be psychological or physical, or both. Dependence can occur after using them for a few months and is not related to the size or physical effect of the daily dose taken. Dependency can still develop for people on long-term, low doses.
People who are psychologically dependent feel as though they can’t cope without benzodiazepines. They crave the drug and find it very difficult to stop using it.
People who are physically dependent on benzodiazepines have become used to functioning with the drug present.
If a dependent person suddenly stops taking benzodiazepines, or severely cuts down their dose, they may experience physical withdrawal symptoms as their body readjusts to functioning without the drug.
Withdrawal symptoms from benzodiazepines vary from person to person, but can be quite severe. Some people have no symptoms at all, while others may have symptoms lasting from a few weeks or months to a year. Symptoms tend to come and go, but all withdrawal symptoms eventually disappear as the body adjusts to functioning without the drug.
Withdrawal symptoms can include:
|aching or twitching muscles|
|faintness or dizziness|
|nausea, vomiting and stomach pains|
|inability to sleep properly|
|anxiety and irritablity|
|heightening of the senses of sight, touch, hearing, smell and taste.|
Other less common withdrawal symptoms may include delirium, delusions, hallucinations, seizures and paranoia.
People who have been using benzodiazepines for more than a month should not suddenly stop taking them withut seeing a doctor or health worker. A slow reduction in dose over time is recommended to reduce the severity of the withdrawal symptoms. If you suffer from anxiety and/or insomia keep in mind they may simply be withdrawal symptoms. If so, these symptoms will eventually cease.
