Key Takeaways
- Xanax can paradoxically cause or worsen anxiety through a phenomenon called rebound anxiety.
- Rebound anxiety occurs when the calming effects of Xanax wear off and anxiety returns at levels more intense than before taking the medication.
- Tolerance to Xanax can develop within 2-4 weeks of daily use, meaning the same dose provides less relief over time.
- Between-dose withdrawal (also called inter-dose withdrawal) can produce anxiety symptoms between scheduled doses as the drug wears off.
- Approximately 40% of long-term benzodiazepine users experience significant anxiety symptoms that are actually caused by the medication itself.
- Paradoxical reactions — where Xanax produces the opposite of its intended effect — have been documented, particularly in elderly patients and children.
How Can an Anti-Anxiety Medication Cause Anxiety?
It seems contradictory that a drug designed to treat anxiety could cause it. But Xanax (alprazolam) has several pharmacological properties that make this paradox very real for many users.
Rebound Anxiety
Xanax has a relatively short half-life (approximately 11 hours). As the drug leaves your system between doses, the brain's anxiety circuits rebound — sometimes overshooting their baseline level. This produces anxiety that is worse than what you experienced before taking the medication.
The cycle looks like this:
- Take Xanax → anxiety decreases
- Drug wears off → anxiety rebounds higher than baseline
- Take next dose to relieve rebound anxiety
- Brain adapts (tolerance develops)
- Higher doses needed → worse rebound → increasing dependency
Tolerance-Driven Anxiety
With regular use, your brain adapts to Xanax by reducing the sensitivity of its GABA receptors. This means:
- The same dose produces less anxiety relief
- Your baseline anxiety level increases
- You need more Xanax to feel the same level of calm
- Without the drug, your anxiety is now worse than it was originally
Inter-Dose Withdrawal
Because Xanax wears off relatively quickly, some users experience mini-withdrawal episodes between their scheduled doses. Symptoms include:
- Heightened anxiety and nervousness
- Tremors and shakiness
- Racing heart
- Sweating
- Difficulty concentrating
- Irritability
These symptoms often feel like worsening of the original anxiety condition, but they are actually caused by the medication cycle.
Paradoxical Reactions
In rare cases, Xanax produces paradoxical effects — the opposite of its intended action:
- Increased anxiety and agitation
- Hostility and aggression
- Impulsiveness
- Hallucinations
- Restlessness
Paradoxical reactions are more common in certain populations including elderly patients, children, individuals with a history of aggression, and people with certain personality disorders.

Breaking the Cycle
If Xanax is causing or worsening your anxiety:
- Do not stop abruptly — Xanax withdrawal can cause seizures and is potentially life-threatening
- Speak with your doctor about a gradual tapering plan
- Consider switching to a longer-acting benzodiazepine or non-benzodiazepine alternative
- Engage in therapy — CBT is highly effective for anxiety and can provide lasting relief without medication risks
- Explore non-medication approaches — exercise, meditation, and breathing techniques can reduce anxiety
Trailhead Treatment Center provides effective anxiety treatment without dependence risk to support lasting recovery and wellness.
