Xanax, Klonopin, Ativan, Valium. These are the benzodiazepines people most often try to quit on their own. That attempt can be dangerous. Like alcohol withdrawal, stopping benzodiazepines abruptly can trigger seizures and other serious complications. The timeline is also longer than most people expect, often stretching for weeks. This is why doctors use a gradual taper instead of a sudden stop. If you or your loved one is dependent on a benzo, please do not quit cold turkey. Medical supervision keeps the process safe.
