Thinking about cutting back or stopping?

For people using benzodiazepines regularly, it is advised to seek medical advice before stopping as they may be dependent. Benzodiazepine withdrawal can trigger seizures. Withdrawal symptoms may be unpleasant, but will lessen over time. Common withdrawal symptoms include headaches, dizziness, nausea, aching muscles, poor sleep, low mood, irritability, hallucinations, paranoia, anxiety and cravings.

Sometimes it can take a few attempts to cut back or stop.

  • Focus on reasons for cutting down or stopping
  • Avoid ‘triggers’ (i.e. things associated with using such as places, people and stressful situations)
  • Ask a friend, family member or health professional for support
