Brain zaps, also known as “brain shivers” or “electric shock sensations,” are a common withdrawal symptom associated with discontinuing some antidepressant and anti-anxiety medications, including selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). Xanax (alprazolam) is a benzodiazepine that affects the central nervous system, but brain zaps are not typically reported as a withdrawal symptom of Xanax. However, sudden discontinuation or rapid tapering of Xanax after prolonged use can cause a range of withdrawal symptoms, including anxiety, agitation, insomnia, tremors, muscle cramps, and seizures. It’s important to follow a doctor’s instructions for tapering off Xanax to minimize the risk of withdrawal symptoms.
