Klonopin is the brand name for Clonazepam, a benzodiazepine anticonvulsant manufactured by Genentech (Roche). It is FDA-approved to treat seizure disorders (including Lennox-Gastaut syndrome, akinetic seizures, and myoclonic seizures) and panic disorder with or without agoraphobia. It is also sometimes prescribed off-label for generalized anxiety disorder, insomnia, restless legs syndrome, and essential tremor.
Klonopin works by enhancing the activity of gamma-aminobutyric acid (GABA), the brain's primary inhibitory neurotransmitter. It binds to the benzodiazepine site on GABA-A receptors, which increases inhibitory signaling in the central nervous system. This produces calming, anticonvulsant, and anti-anxiety effects. Klonopin has a relatively long duration of action compared to some other benzodiazepines, which is why it is effective for both seizure prevention and panic disorder management.

Klonopin (Clonazepam) has a findability score of 45 out of 100, meaning it can be moderately difficult to find in stock at your local pharmacy. An active shortage of Clonazepam tablets has persisted since March 2023, with manufacturers like Teva experiencing intermittent back orders on the 0.5 mg and 2 mg strengths. As of early 2026, some strengths have been reverified as available, but supply disruptions continue. Using Medfinder can help you quickly locate pharmacies near you that currently have Klonopin or Clonazepam in stock.

Note that Klonopin is generally not available through telehealth platforms due to DEA regulations on prescribing controlled substances.
Yes. Klonopin (Clonazepam) is classified as a DEA Schedule IV controlled substance. This means it has a recognized medical use but carries a risk of abuse, misuse, addiction, and physical dependence. The FDA requires a boxed warning on all benzodiazepines stating that concomitant use with opioids may result in profound sedation, respiratory depression, coma, and death. Patients should never stop Klonopin abruptly — doses must be tapered gradually under medical supervision to avoid potentially dangerous withdrawal symptoms, including seizures.
Serious side effects can include respiratory depression (especially when combined with opioids or alcohol), suicidal thoughts, paradoxical agitation, and severe withdrawal symptoms if stopped abruptly. Contact your doctor immediately if you experience any serious side effects.

Klonopin (Clonazepam) remains an important medication for patients with seizure disorders and panic disorder, but the ongoing shortage that began in 2023 continues to make it challenging to find in 2026. With a findability score of just 45, many patients are experiencing difficulty locating their medication at local pharmacies. Generic Clonazepam is affordable — as low as $8 with a discount coupon — but availability is the primary concern. If you're struggling to find Klonopin in stock, Medfinder can help you search pharmacies near you in seconds. Talk to your doctor about alternatives if your pharmacy continues to be out of stock.
