At a glance

  • Lorazepam, usually known as Tavor, is a benzodiazepine with an anxiety-relieving, calming and sleep-promoting effect.
  • Already after two to four weeks of daily intake a dependence can arise, sometimes even earlier, even without the dose rising.
  • After a longer intake, lorazepam must never be stopped abruptly, because that can be dangerous and even trigger seizures.
  • Safe stopping means slow tapering over weeks to months according to a medical plan, never on your own.
  • Lorazepam only treats the symptoms, for the long-term treatment of anxiety there are better options like psychotherapy.

Exactly this rapid, noticeable effect also makes it risky, however, because lorazepam belongs to the benzodiazepines, and they have a high dependence potential. What is tricky about it is often underestimated in everyday life: a dependence can arise after just a few weeks, and a wrong, too fast stopping can become dangerous. Many people take lorazepam without knowing exactly what they have to pay attention to, and that is exactly what we want to change here. This guide explains in plain language how lorazepam works, why even a short intake can cause dependence and what a safe, slow tapering looks like that, unfortunately, is not always explained sufficiently in the family doctor's practice. The aim is to inform you so that you can use lorazepam safely and in close exchange with your medical practice. Those who know the most important points need not be afraid of the medicine but can use it consciously and safely.

How lorazepam works

Lorazepam belongs to the group of the benzodiazepines. It strengthens in the brain the effect of the body's own messenger GABA, which calms the nervous system. GABA works like a natural brake for overactive nerve cells, and lorazepam strengthens exactly this brake. Thereby lorazepam works on several levels at once: it relieves anxiety, it calms, it promotes sleep, it relaxes the muscles and it works anticonvulsant. This versatility is at the same time a strength and a weakness, because a medicine that dampens so comprehensively also intervenes deeply in the nervous system. This broad effect explains why it is used with very different complaints, for example with acute anxiety and tension states, with panic attacks, short term with severe sleep problems or with certain seizures. It is also sometimes given before operations or stressful examinations in order to relieve anxiety and tension. The effect sets in quickly and is clearly noticeable, which gives many sufferers quick relief and makes the medicine so popular in acute situations. Exactly this fast effect is, however, also a reason why a habituation arises so easily. The brain quickly learns to connect the relief with the medicine, and that makes it hard to do without it again later.

Dependence already after two to four weeks

The most important point you have to know about lorazepam is the high dependence risk. Benzodiazepines should, according to professional information, generally only be prescribed for short periods, often a frame of about two to four weeks is named. A longer use should only happen with a compelling reason and after careful weighing, because the risk then rises clearly. The reason: already after a few weeks of daily intake a physical and mental dependence can develop, some people even report a habituation after an even shorter time. In Germany an estimated more than one million people are dependent on benzodiazepines, which shows how widespread and underestimated this problem is. Especially tricky is the so-called low-dose dependence: with this the dose is not even increased but the body still cannot manage without the medicine. Unlike with the classic picture of an addiction, sufferers thus do not increase the amount but stay inconspicuously at a small dose and often do not notice the dependence at all. Because the dose stays the same, this form of dependence often goes unnoticed for a long time, neither by the sufferers nor by the medical practice. Only when trying to leave the medicine out does it then show that the body has long needed it.

Even a short intake can cause dependence

Lorazepam is not a medicine for continuous use. Already after two to four weeks of daily intake a dependence can arise, which is why it should only be taken short term and under close medical guidance. If lorazepam is prescribed to you over a longer period, actively ask how long the intake is planned and what the stopping should look like. But never stop the medicine on your own or abruptly. An open question in the practice is completely normal here and shows that you handle the medicine responsibly.

Safe stopping: the slow tapering

Unlike with many other medicines, lorazepam cannot simply be left out after a longer intake. While a painkiller or an antibiotic can usually be stopped without problems at the end of the treatment, this is different with a benzodiazepine after a longer use. After more than about two weeks the body has got used to the active substance, and an abrupt stop can trigger severe withdrawal symptoms. The safe way is a slow, step-by-step tapering that is always planned and accompanied by the medical practice. There is no blanket instruction, because every single body reacts differently. As a rule, the dose is reduced very carefully in small steps over weeks to months. Often a small part of the dose is reduced about every one to two weeks, sometimes a switch is also made to a longer-acting benzodiazepine such as diazepam, which is easier to taper. How big the individual steps are and how much time lies between them always depends on how well you tolerate them and is adjusted if needed. Behavioural therapy, relaxation techniques and exercise help alongside. Important is patience: the slower the tapering, the milder the process usually proceeds. A too fast pace, on the other hand, often leads to complaints that make the stopping unnecessarily hard and discourage sufferers.

Never stop abruptly: that can be dangerous

Never stop lorazepam from one day to the next after a longer intake. An abrupt stop can trigger severe and in rare cases even life-threatening withdrawal symptoms such as seizures, confusion or a delirium. Strong anxiety, restlessness and sleeplessness are also common. The stopping therefore always belongs in medical hands and should happen according to an individual plan. Speak with your medical practice before you change anything. Even if you have the feeling that you no longer need the medicine, the slow tapering is the safe way.

The rebound effect: when the complaints return

When stopping lorazepam, many people experience that the original complaints temporarily return intensified, that is for example the anxiety, the inner restlessness or the sleeplessness. Some sleep especially badly in this phase or feel more nervous than before, which can be very distressing. This phenomenon is called the rebound effect. It arises because the nervous system has got used to the dampening effect and briefly overshoots when stopping. What is tricky about it is that this effect is easily confused with a relapse of the actual illness. Many then think they still need the medicine, but it is usually a temporary withdrawal symptom that subsides over time on its own. This confusion is one of the main reasons why some people hold on to a benzodiazepine for years, although a stopping would have long been possible. Exactly for this reason it is so valuable to have the stopping medically accompanied, because this way rebound and a real relapse can be told apart better. The medical practice can assess whether the complaints are temporary or whether the underlying illness needs to be treated further.

Further side effects and risks

Like all benzodiazepines, lorazepam can make you tired and drowsy, promote dizziness and reduce attention, especially at the start of the treatment. Many of these effects ease somewhat over time but are clearly noticeable especially in the first days. Concentration and memory can also suffer. Because the reaction ability is restricted, driving and operating machines are often not possible. In older people the risk of falls is increased, and so-called paradoxical reactions can occur, with which restlessness or aggression appear instead of calming. In older people in particular, lorazepam should therefore be used especially cautiously and in a low dose, because they react more sensitively and the active substance is broken down more slowly in them. A particularly important warning concerns the combination with other dampening substances. This can intensify the effect of lorazepam so much that it becomes dangerous, which is why it should never happen without medical consultation.

Topic The most important in brief
Substance group Benzodiazepine, anxiety-relieving and calming via GABA
Use Acute anxiety, panic, short term sleep problems
Dependence Possible already after two to four weeks
Stopping Never abruptly, taper slowly with medical guidance
Important interaction Alcohol and opioids: risk of respiratory depression

Caution with alcohol and dampening substances

Do not drink alcohol during the intake of lorazepam and be careful with other dampening substances such as opioids, sleeping pills or certain painkillers. In combination the calming effect can become so strong that breathing is slowed dangerously. Especially the combination of a benzodiazepine and an opioid is considered risky. Always tell your medical practice and your pharmacy what else you take. This also applies to over-the-counter medicines and herbal preparations that you might not consider important.

The bottom line is that lorazepam is an effective medicine that helps quickly and reliably in acute situations but that demands great respect. It is not the medicine that makes anxiety generally bad or dangerous, but a tool that can be very valuable in the right situation and for the right duration. The decisive point is the duration: lorazepam is intended for short, clearly limited use, not for continuous use. Those who know this and plan the stopping in time and slowly with the medical practice can use the medicine sensibly and avoid an unwanted dependence. With an anxiety disorder, lasting sleep problems or frequent heart palpitations, the conversation about a long-term treatment that manages without a dependence risk is worthwhile, for example a psychotherapy or suitable antidepressants. Lorazepam can serve as a short-term bridge until the actual treatment takes effect.

Frequently asked questions about lorazepam (Tavor)

Lorazepam is a benzodiazepine that is usually prescribed under the trade name Tavor. It works anxiety-relieving, calming, sleep-promoting, muscle-relaxing and anticonvulsant. It is used above all with acute anxiety and tension states, with panic attacks and short term with severe sleep problems. Lorazepam is prescription only and should, because of the high dependence risk, only be taken for as short a time as possible.
Dependence can arise with lorazepam after a short time already, often after just two to four weeks of daily intake, sometimes even earlier. Therefore professional information recommends prescribing benzodiazepines only for short periods. Tricky is the so-called low-dose dependence, with which the dose is not even increased but the body still cannot manage without the medicine. Important is therefore a short, closely medically accompanied use.
After more than about two weeks of intake, the body has got used to lorazepam. A sudden stop can then trigger severe withdrawal symptoms, in rare cases even life-threatening ones such as seizures or a delirium. Increased anxiety, restlessness and sleeplessness are also common. Therefore lorazepam must, after a longer intake, never be stopped from one day to the next but only tapered slowly and according to a medical plan.
The tapering should always be planned and accompanied by the medical practice, there is no blanket instruction. As a rule, the dose is reduced very slowly and step by step over weeks to months, often in small steps every one to two weeks. Sometimes a switch is made to a longer-acting benzodiazepine such as diazepam, which is easier to taper. Behavioural therapy, relaxation techniques and exercise help alongside. The slower the tapering, the milder the process.
The rebound effect is the intensified reappearance of the original complaints when stopping, that is for example anxiety, inner restlessness or sleeplessness, often stronger than before the treatment. This is easily confused with a relapse of the underlying illness but is usually a temporary withdrawal symptom that subsides over time. Therefore it is important to accompany the stopping medically and not to interpret such phases as proof that you need the medicine permanently.
Common side effects are tiredness, drowsiness, dizziness and reduced attention, especially at the start of the treatment. Concentration and memory problems can also occur. In older people there is an increased risk of falls, and paradoxical reactions with restlessness or aggression instead of calming can occur. The reaction ability is reduced, so driving and operating machines are often not possible.
No, alcohol should be avoided during the intake of lorazepam. Alcohol and other dampening substances such as opioids, sleeping pills or certain painkillers intensify the calming effect and can slow breathing dangerously. Especially the combination of a benzodiazepine and an opioid is considered dangerous. Always inform your medical practice and your pharmacy about all substances you take.
Lorazepam works quickly and reliably against acute anxiety but only treats the symptoms and not the cause. For the longer-term treatment of anxiety disorders there are more suitable options, for example a psychotherapy and non-addictive medicines such as certain antidepressants. Lorazepam is therefore rather intended for short, clearly limited phases. The medical practice decides together with you about the best long-term treatment.
Lorazepam works quickly and well, which is why it is prescribed often and sometimes longer than is actually recommended. The high addiction danger of benzodiazepines is not always explained sufficiently. This is no reason to panic but a good reason to ask yourself how long the intake is planned and what the later stopping should look like. An informed use protects best against an unwanted dependence.
