Ativan (lorazepam) is not typically used to treat brain zaps, which are a common symptom of antidepressant and antipsychotic withdrawal. While Ativan is a benzodiazepine that can help alleviate symptoms of anxiety, it can also be habit-forming and cause withdrawal symptoms of its own if used long-term or in high doses. It is important to follow your doctor’s instructions and not stop or change the dosage of any medication without consulting with them first. If you are experiencing brain zaps, it is best to talk to your doctor about the best course of treatment for your individual situation.
