What are Xanax withdrawal symptoms?
Direct Answer
Xanax withdrawal symptoms include rebound anxiety (often worse than the original anxiety), insomnia, irritability, muscle tension, tremors, sweating, and difficulty concentrating. In severe cases — particularly after high doses or prolonged use — withdrawal can cause seizures, which is why medical supervision is critical. Symptoms typically begin within 6-12 hours of the last dose due to Xanax's short half-life. The acute phase lasts 1-4 days, but protracted withdrawal symptoms (anxiety, insomnia, cognitive fog) can persist for weeks to months.
Based on published clinical trial data and FDA prescribing information. This is not medical advice — always consult your healthcare provider.
Supporting Evidence
Stopping Safely
Abrupt alprazolam discontinuation can cause life-threatening seizures. Benzodiazepine withdrawal is one of the two withdrawal syndromes (with alcohol) that can be directly fatal. Tapering must be slow and medically supervised.
Warning symptoms:
- Seizures — call 911 immediately
- Tremors or uncontrollable shaking
- Extreme anxiety or panic disproportionate to your normal level
Side Effects
Serious (rare)
- Physical dependence and addiction (40–60% of patients using >6 weeks)
- Withdrawal seizures if stopped abruptly — can be life-threatening
- Respiratory depression when combined with opioids or alcohol
