Xanax vs. Klonopin
See how Xanax and Klonopin compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Xanax acts fast and wears off quickly, while Klonopin takes longer to kick in but stays in the body for much longer.
Klonopin is FDA-approved for seizure disorders and panic disorder, while Xanax is approved for panic disorder and generalized anxiety disorder.
Both drugs carry the same boxed warnings for abuse, physical dependence, and dangerous interactions with opioids.
Xanax vs. Klonopin Drug Summary
Xanax
Xanax (alprazolam) is a short-acting benzodiazepine approved to treat generalized anxiety disorder and panic disorder in adults. It comes as an immediate-release tablet, usually taken two to four times a day, with the dose raised slowly every few days.
Klonopin
Klonopin (clonazepam) is a longer-acting benzodiazepine approved to treat certain seizure disorders and panic disorder in adults. It comes as a tablet or a dissolving wafer, usually taken once or twice a day since its effects last much longer than Xanax's.

Xanax vs. Klonopin Indications
Xanax
Xanax is FDA-approved for two conditions: generalized anxiety disorder and panic disorder, with or without agoraphobia. It's meant for short-term or as-needed use, and doctors typically reassess the need for continued treatment on a regular basis.
Generalized anxiety disorder (GAD)
Panic disorder, with or without agoraphobia
Short-term relief of anxiety symptoms
Klonopin
Klonopin is FDA-approved for panic disorder and for specific seizure types, including Lennox-Gastaut syndrome and absence seizures. Doctors also prescribe it off-label for generalized anxiety disorder, restless legs syndrome, and insomnia, though it isn't FDA-approved for those uses.
Panic disorder, with or without agoraphobia
Lennox-Gastaut syndrome seizures
Akinetic and myoclonic seizures
Xanax vs. Klonopin Pros and Cons
Xanax
Xanax works quickly, often easing panic symptoms within an hour, but its effects wear off fast enough that anxiety can return before the next dose is due. It's a widely used generic that most insurance plans cover.
Pros
Fast onset, often within 20-60 minutes
Available in four tablet strengths for fine dosing
Extended-release version (Xanax XR) allows less frequent dosing
Widely covered generic with low typical copays
Cons
Short half-life means doses are often needed several times a day
Higher risk of interdose rebound anxiety between doses
Not approved or used for seizure disorders
Fast onset raises misuse potential
Klonopin
Klonopin's long half-life means steadier blood levels and less risk of anxiety returning between doses, but it can take longer to feel the calming effect and daytime grogginess is common. Brand-name Klonopin has largely been replaced by inexpensive generic clonazepam.
Pros
Long half-life allows once or twice daily dosing
Steadier blood levels with less interdose rebound
Also approved for several seizure disorders
Orally disintegrating tablet option available
Cons
Slower onset than Xanax for acute panic symptoms
Not FDA-approved for generalized anxiety disorder
Higher reported rates of ataxia and behavior changes
Long half-life can cause next-day sedation buildup
