The duration of lorazepam withdrawal can vary from person to person, depending on several factors such as the dosage, frequency, and duration of use, as well as individual differences in metabolism, genetics, and overall health. Generally, lorazepam withdrawal symptoms can start within a few hours to a few days after the last dose and can last anywhere from a few days to several weeks, with the peak of intensity usually occurring within the first week or so. However, some people may experience protracted withdrawal symptoms that can last for several months or even years. It is important to seek professional medical assistance when withdrawing from lorazepam or any benzodiazepine to ensure a safe and effective detoxification process.
