What are benzodiazepines and z-drugs?
Benzodiazepines such as alprazolam (Xanax), clonazepam (Klonopin), and lorazepam (Ativan) are prescribed mostly for anxiety, panic disorder, and insomnia. Z-drugs such as zolpidem (Ambien) are sleep medications that act on the same receptors. Both strengthen the effect of gamma-aminobutyric acid (GABA), the brain’s own calming messenger.
Taken daily for weeks or months, these drugs teach the brain to rely on that extra calming signal. That adaptation is physical dependence, and it happens to people who take their medication exactly as prescribed. Physical dependence is not addiction.
Dr. Mark Leeds, an osteopathic physician and deprescribing specialist in Fort Lauderdale, Florida, serves on the medical advisory board of the Benzodiazepine Information Coalition.

Each card below answers one question on its own page, from what these drugs are to the risks and side effects of long-term use and safe tapering and discontinuation.
What Are Benzodiazepines?
These drugs act on GABA, the brain's calming messenger, and over time the brain comes to rely on them.
Risks and Side Effects
Long-term use of benzodiazepines can lead to dependence, memory issues, impaired coordination, and increased risk of falls or accidents.
Safe Tapering and Discontinuation
A benzodiazepine should come down gradually, over months, at the patient's pace. Stopping suddenly is never the safe way off.
Regular use changes how the brain responds.
Tolerance
Over months of daily use, the same dose can do less, and withdrawal symptoms can appear between doses.
Withdrawal
A dose that falls too fast can bring anxiety, insomnia, muscle tension, and sensitivity to light and sound. Stopping suddenly can cause seizures.
Protracted Withdrawal
For some people, symptoms come and go in waves for months after the last dose. In most cases, protracted withdrawal eases with time.
A safe taper is slow and patient-directed.
These medications do not have to be stopped all at once, and they should not be. Dr. Leeds tapers gradually, usually over months, guided by the Ashton Manual, written by Professor C. Heather Ashton, and the Maudsley Deprescribing Guidelines. Where it helps, the taper starts with a crossover to diazepam (Valium), a longer-acting benzodiazepine.
Reductions get smaller as the dose falls, and the taper holds whenever symptoms need time to settle. Every step rests on informed consent: the risks first, the alternatives, an exit plan, and the right to decline. Read more about medically supervised benzodiazepine tapering.
A Plan the Patient Shapes
Each reduction and every hold are decided together, and they change when symptoms call for it.

Common questions about benzodiazepines
Short answers to common questions. This page is education, not medical advice, and reading it does not create a doctor-patient relationship.
What are benzodiazepines used for?
Benzodiazepines are prescribed mainly for anxiety, panic disorder, and insomnia. The Ashton Manual advises keeping use to a few weeks, because the brain adapts to them with regular use.
What are the potential side effects of benzodiazepines?
Drowsiness, dizziness, unsteadiness, memory problems, and, in older adults, falls. Physical dependence can develop even at prescribed doses, and in 2020 the U.S. Food and Drug Administration (FDA) updated the benzodiazepine boxed warning to cover dependence and withdrawal.
How can I safely taper off benzodiazepines?
Gradually, usually over months, with a physician who adjusts the pace to how the patient feels. Never stop a benzodiazepine suddenly, and work with your prescriber before changing any dose.
What should I do if I experience withdrawal symptoms?
Tell the physician supervising your taper. The usual answer is to hold the dose until symptoms settle. For severe confusion, a seizure, or thoughts of suicide, call 911, go to the nearest emergency room, or call or text the 988 Suicide and Crisis Lifeline.
