Benzodiazepine addiction explained: causes, signs and recovery
Benzodiazepine addiction is a loss of control over sedative medicines such as diazepam, lorazepam or alprazolam, where you keep taking them despite harm and cannot cut down. It often starts with a legitimate prescription for anxiety or sleep. Physical dependence can develop when these medicines are taken steadily for several days to weeks, even as prescribed (FDA, 2020).

The short answer
Recovery follows a set order. A doctor assesses your use and your health first. The dose is then reduced slowly under supervision, never stopped at once. Therapy also addresses the original reason for the prescription, usually anxiety or poor sleep. Aftercare protects the progress.
- Medical assessment of use, other substances and mental health
- Gradual, supervised taper with a personal plan
- Therapy for the underlying anxiety, panic or sleep problem
- Aftercare and relapse prevention
What are benzodiazepines?
Benzodiazepines are prescription sedatives that calm the nervous system. They are approved for generalised anxiety disorder, panic disorder, social phobia, insomnia and seizures (FDA, 2020). Doctors also use them for short periods during alcohol withdrawal.
They work fast. That speed is part of their appeal and part of their risk. The brain adapts to a regular dose. Over time the same dose does less, and stopping causes rebound symptoms.
Common brand names in Switzerland include Valium, Temesta, Xanax and Ativan (FOPH, 2023). Related sleeping pills known as Z-drugs, such as zolpidem, act on the same brain system and carry similar dependence risks.
- Diazepam (Valium): long-acting
- Lorazepam (Temesta, Ativan): intermediate-acting
- Alprazolam (Xanax): short-acting
- Midazolam: very short-acting, mainly used in hospital
Short-acting benzodiazepines wear off faster between doses. Rebound anxiety between doses can then encourage more frequent use.

Benzodiazepine use in Switzerland
Sedative use is common in Switzerland, and a small but steady share of people take these medicines long term. Roughly 1 in 12 people in Switzerland (8.3%) used a sleeping pill or sedative at some point in 2022 (FOPH, 2023). Daily or near-daily use was reported by 2.1%, and use lasting over a year by 1.6% (FOPH, 2023).
Near-daily use is highest among women and people aged 75 and over. Most supplies come from doctors or prescriptions (83%), but almost 7% of people who took these medicines in the past year got them from acquaintances (FOPH, 2023).
Comparable data from the United States show how often use turns into misuse. 5.3 million adults there (2.2%) misused benzodiazepines in a single year, which was 17.2% of all use (Maust et al., 2019). Our page on prescription drug addiction treatment in Switzerland covers sedatives, painkillers and stimulants together.
Why benzodiazepine addiction develops
Problem use of benzos develops from regular use, the brain's adaptation to the drug and the problem the drug was meant to treat. The FOPH notes that dependence on medicines can build up gradually, even from appropriate prescribing (FOPH, 2026). Many people never set out to misuse anything.
Dependence and addiction are not the same thing. Physical dependence means the body needs the drug to avoid withdrawal. Addiction adds loss of control, craving and use despite harm. Dependence can exist without addiction, but it often comes first.
Several factors raise the risk:
- Taking them every day for more than a few weeks
- Higher doses or short-acting products
- Anxiety, panic, insomnia, depression or trauma
- Past or current problems with alcohol or other drugs
- A family history of addiction
- Getting extra supplies outside a prescription
- Using the medicine to cope with stress rather than as prescribed
How fast can you get addicted to benzos? No study gives a reliable timeline for addiction itself. What is established is that the body can become dependent after several days to weeks of regular use (FDA, 2020). The FOPH therefore advises a clear reason, a small dose, short use and no abrupt stopping (FOPH, 2026).
Signs of benzodiazepine addiction
The clearest signs are needing the medicine to get through the day and being unable to cut down. Doctors look for a pattern over the past 12 months. One sign alone proves little. Several together point to a problem.
Signs you may notice in yourself:
- Taking more, or for longer, than prescribed
- Failed attempts to reduce the dose
- Strong urges to take a tablet
- Needing a higher dose for the same effect
- Anxiety, insomnia or tremor when a dose is late
- Running out early and seeking new prescriptions
- Drowsiness, poor coordination or memory gaps
- Hiding use from family or your doctor
Family members often notice different signs. These include slurred speech, unusual sleepiness, mood swings, withdrawal from friends, missed work and tablets from several doctors or pharmacies. If you are worried about someone close to you, our guide on how to help a loved one into rehab explains how to start the conversation.
Benzos with alcohol or opioids
Combining benzodiazepines with alcohol or opioids is the most dangerous pattern of use. All three slow breathing. The FDA states that misuse can lead to overdose or death, especially when benzodiazepines are combined with opioid painkillers, alcohol or illicit drugs (FDA, 2020).
In 2021, nearly 14% of overdose deaths involving opioids in the United States also involved benzodiazepines (NIDA, 2022). The FOPH tracks strong painkillers such as oxycodone and morphine alongside sedatives in its Swiss survey (FOPH, 2023). Taking both at once calls for close medical supervision.
Alcohol and benzodiazepines also mask each other. Some people use one to manage withdrawal from the other. Treatment must then cover both substances at once. Our guides on alcohol addiction signs and recovery and opioid addiction treatment explain those parts of the picture.

- Call 145 for poison advice from Tox Info Suisse (ch.ch, 2026)
How doctors diagnose it
Doctors diagnose sedative use disorder through a detailed conversation, a review of prescriptions and a physical and mental health check. They ask which medicines you take, at what dose, for how long and from which sources. They ask what happens when a dose is missed.
The answers are matched against the DSM-5 or ICD-11 criteria for sedative use disorder. A urine test can confirm recent use. The doctor also screens for alcohol, opioids, depression, anxiety disorders and sleep disorders. This matters because each one changes the treatment plan and the safety of the taper.
Specialist treatment is advisable when any of the following apply:
- You take benzodiazepines daily and cannot reduce the dose
- You also drink heavily or use opioids
- You have had seizures or severe withdrawal before
- Anxiety, depression or suicidal thoughts are getting worse
- Use has caused accidents, falls or problems at work
An honest account of all substances is the single most useful thing you can bring. Swiss medical secrecy protects what you share; our guide to confidentiality in Swiss rehab explains the legal rules.
Tapering explained step by step
Tapering means reducing the dose gradually under medical supervision until you stop. It is the standard way to come off benzodiazepines safely. Stopping abruptly or reducing the dose too quickly can cause withdrawal reactions, including seizures (FDA, 2020).
No standard tapering schedule suits everyone (FDA, 2020). Your doctor sets the pace based on your dose, the product, how long you have taken it and your health. This guide describes the process, not doses. Never change your own dose without your doctor.
- Step 1: full assessment of all medicines, alcohol and other drugs
- Step 2: a written, personal reduction plan agreed with you
- Step 3: in some cases, a switch to a longer-acting benzodiazepine
- Step 4: small reductions at intervals, with regular check-ins
- Step 5: a pause or slower pace if withdrawal becomes hard
- Step 6: therapy and sleep support running alongside
- Step 7: follow-up after the last dose
Withdrawal can still occur during a careful taper. Typical symptoms are anxiety, insomnia, irritability, muscle pain, tremor, blurred vision and memory problems (FDA, 2020). A protracted withdrawal syndrome can last beyond 4 to 6 weeks (FDA, 2020).
Most tapers can be run as an outpatient. Inpatient care makes sense at high doses, with alcohol or opioid use, a history of seizures or repeated failed attempts. Our guide on what happens during medical detox describes supervised withdrawal in a clinic.
Treating the anxiety or insomnia underneath
Lasting recovery depends on treating the problem the medicine was covering. Without that, anxiety or sleeplessness often returns during the taper and pulls people back to the tablets. The FDA advises doctors to offer non-drug alternatives for stress, anxiety and insomnia (FDA, 2020).
Anxiety is common in Switzerland. Moderate to severe generalised anxiety symptoms affected 6.3% of the Swiss population in 2022 (Obsan, 2024). Six in ten Swiss addiction services say that over 60% of their clients also have another mental disorder (Addiction Switzerland, 2025).
Treatment for benzo dependence therefore combines several approaches. Cognitive behavioural therapy teaches skills to manage worry and panic. CBT for insomnia rebuilds natural sleep. Some people need a different, non-addictive medicine for anxiety or depression, chosen by a psychiatrist. When addiction and a mental health condition occur together, Swiss clinics treat both at once; our page on dual diagnosis treatment explains how.
- Cognitive behavioural therapy for anxiety and panic
- CBT for insomnia and sleep routines
- Psychiatric review of other medication
- Stress management, exercise and relaxation training
- Group therapy and peer support
Benzodiazepine addiction recovery in Switzerland
Recovery from benzo dependence usually takes months, and the taper is only the first part. NIDA states that medically assisted detoxification is only the first stage of treatment (NIDA, 2018). Therapy and follow-up do most of the long-term work.
Your family doctor is usually the best first contact in Switzerland. They can review your prescriptions, start a taper and refer you to a psychiatrist or addiction service. SafeZone.ch offers free, anonymous online addiction counselling, developed by the FOPH and Infodrog (SafeZone.ch, 2026).
A residential clinic suits people with high doses, mixed substance use, serious anxiety or depression, or several failed attempts at home. A good clinic is led by a psychiatrist, can manage withdrawal on site and gives you a written aftercare plan. Our guide to choosing a rehab clinic lists the questions to ask.
A setback during recovery does not mean failure. It means the plan needs adjusting. If you would like help finding a Swiss clinic that treats benzodiazepine addiction alongside anxiety or sleep problems, we can shortlist suitable options, free and confidential.

Frequently asked questions
Can you take benzodiazepines long term without becoming addicted?
Some people take them for long periods without signs of addiction, but most develop physical dependence. That means stopping still needs a supervised taper. Regular review with your doctor is the safest approach.
Can you overdose on benzodiazepines?
Yes. The risk is highest when they are combined with alcohol, opioids or other sedatives, because breathing can slow dangerously. In Switzerland, call 144 if someone cannot be woken.
Can you stop benzodiazepines at home?
Many people can taper at home with close support from their doctor. Stopping suddenly without medical advice is not safe. High doses, mixed substance use or a seizure history usually call for a clinic.
How long does benzodiazepine withdrawal last?
It varies with the product, the dose and the length of use. According to the FDA, some people have withdrawal symptoms that last longer than 4 to 6 weeks. Your doctor adjusts the pace of the taper to keep symptoms manageable.
