The duration of Ativan withdrawal symptoms can vary depending on the individual, the dose of Ativan taken, and the duration of use. In general, acute withdrawal symptoms can last from a few days up to a few weeks. However, some people may experience post-acute withdrawal symptoms (PAWS) that can last for several months or even years after discontinuing Ativan. These symptoms can include anxiety, depression, insomnia, and cognitive difficulties. It’s important to note that the duration and severity of withdrawal symptoms can be reduced with proper medical treatment and support.
