Buspar vs Klonopin
Introduction
For patients with anxiety disorders or symptoms of anxiety, certain medications that alter the concentrations of compounds in the brain that are linked to mood can help manage these conditions. Buspar and Klonopin are two such drugs frequently prescribed for anxiety relief. They each impact different neurotransmitters in the brain, but both can alleviate feelings of nervousness and tension in patients suffering from anxiety.
Buspar, also known as buspirone, is an anti-anxiety medication under the class azapirones. It affects levels of serotonin and dopamine by acting on their receptors to decrease overactivity in your brain which helps reduce fear, tension and enhance mental clarity.
On the other hand, Klonopin is classified as a benzodiazepine primarily affecting gamma-aminobutyric acid (GABA) receptors - it works by enhancing GABA’s effects leading to a reduction in nerve cell activity thus providing calming effect on body's nervous system.

What is Buspar?
Buspirone (the generic name for Buspar) was a significant step forward in the class of anxiolytic drugs, differentiating itself from its predecessor, benzodiazepines. It was first approved by the FDA in 1986 as an effective treatment to reduce symptoms of anxiety without sedation or muscle relaxation. Unlike most anti-anxiety medications which function by interacting with GABA receptors and inducing sleepiness, buspirone operates primarily on serotonin receptors, effectively increasing their activity and thus reducing feelings of fear or tension. It has less potential for dependency compared to earlier classes of anti-anxiety drugs such as benzodiazepines.
In contrast, clonazepam (Klonopin), is a classic example of the benzodiazepine class that has been prescribed since the early 1970s. Klonopin increases levels of free GABA neurotransmitters by enhancing their effect at receptor sites; this effectively “traps” them within neurons longer than usual resulting in a calming effect on overactive brain processes associated with anxiety and panic disorders. Klonopin's influence is not selective like Buspar's - it affects multiple neurotransmitter systems simultaneously including those involving dopamine and norepinephrine, potentially leading to more side effects.
What conditions is Buspar approved to treat?
Buspar and Klonopin are approved for the treatment of different mental health conditions:
- Buspar is primarily used to treat generalized anxiety disorder (GAD), a condition characterized by excessive, long-lasting worry and fear about everyday situations.
- Klonopin, on the other hand, is used for treating panic disorders (including agoraphobia) and for controlling seizures. It also finds use in managing short-term symptoms of anxiety.
How does Buspar help with these illnesses?
Buspar helps to manage anxiety by affecting the amount of serotonin and dopamine available in the synapses of the brain. It does this by altering their uptake or release, so levels can be regulated more effectively. Both serotonin and dopamine are neurotransmitters that act as messengers in the brain and throughout the body, playing crucial roles in mood regulation, cognition, memory, sleep patterns among other things. It is believed that individuals with anxiety disorders may have imbalances in these neurotransmitters' levels. Therefore, by modulating serotonin and dopamine levels, Buspar can limit negative effects of anxiety and aid patients to manage their condition better.
What is Klonopin?
Klonopin is a brand name for clonazepam, which is a benzodiazepine. It works by enhancing the activity of gamma-aminobutyric acid (GABA), an inhibitory neurotransmitter in the brain, thereby producing calming effects. Clonazepam was first approved by the FDA in 1975 and it differs from other drugs like Buspar that act on serotonin receptors.
As Klonopin is not a selective serotonin reuptake inhibitor (SSRI) or similar drug class, it does not affect serotonin levels directly. This difference means its side-effect profile varies from SSRIs; for instance, it can cause sedation as well as potential dependency with long term use - common concerns associated with benzodiazepines such as Klonopin. The enhanced GABA activity can be beneficial for treating anxiety disorders and seizures, especially in patients who don't respond optimally to traditional SSRI medications or similar classes.
What conditions is Klonopin approved to treat?
Klonopin, a type of benzodiazepine, is approved by the FDA for the treatment of:
- Panic disorder (with or without agoraphobia)
- Seizure disorders such as Lennox-Gastaut syndrome or akinetic and myoclonic seizures.
It's worth noting that while Klonopin can be effective in treating these conditions, it should only be used under medical supervision due to its potential for dependency and withdrawal symptoms when discontinued abruptly.
How does Klonopin help with these illnesses?
Gamma-aminobutyric acid (GABA) is a neurotransmitter that plays key roles in the body, including inducing relaxation, reducing anxiety, and helping with sleep. Low levels of GABA have been linked to conditions such as anxiety disorders and panic attacks. Klonopin works by enhancing the action of GABA in the brain, which results in a calming effect on both mind and body. This makes it effective for treating panic disorder and certain types of seizures. Its effects can be felt quickly after administration unlike Buspar which usually takes several weeks to begin working optimally as an anti-anxiety medication. Since Klonopin has potent sedative effects, it's often used when immediate relief from severe symptoms is needed or other medications like Buspar haven't provided sufficient symptom control.
How effective are both Buspar and Klonopin?
Both buspirone (Buspar) and clonazepam (Klonopin) have established histories of success in treating patients with anxiety disorders, and they were initially approved by the FDA within a decade of each other. Since they act on different neurotransmitters, they may be prescribed under different circumstances. The effectiveness of buspirone and clonazepam in alleviating symptoms associated with Generalized Anxiety Disorder was directly studied in several clinical trials; both drugs exhibited efficacy in managing symptoms as well as similar, promising safety profiles.
A 1990 review on double-blind studies involving Buspar demonstrated that it is effective at alleviating symptoms associated with Generalized Anxiety Disorder without leading to dependency or withdrawal syndromes often seen with benzodiazepines. Moreover, its side effect profile is generally well-tolerated even among elderly populations. This same study reported that Buspar does not produce significant sedation or cognitive impairment unlike most anxiolytic agents including Klonopin.
On the other hand, a 2003 systematic review indicated that while Klonopin seems to be more potent than placebo at relieving short-term symptoms of panic disorder it comes along with dependence potential which can lead to withdrawal syndrome upon discontinuation especially if used long-term. Nonetheless due to its rapid onset of action compared to Buspar, Klonopin might still hold merit for acute relief from severe bouts of anxiety or panic attacks provided it's used short term under close medical supervision.

At what dose is Buspar typically prescribed?
Oral dosages of Buspar range from 15–60 mg/day, taken in divided doses. However, studies have shown that 15 mg/day is usually sufficient for treating generalized anxiety disorder (GAD) in most people. Adolescents may be started on a lower dose if tolerated well and the dosage can be increased after a few weeks if there is no response. The maximum dosage that should not be exceeded in any case is 60 mg/day. On the other hand, Klonopin dosages vary significantly based on the condition being treated but ordinarily fall within the range of 0.5-20 mg per day; it's crucial to follow your doctor's instructions closely when using this potent medication.
At what dose is Klonopin typically prescribed?
Klonopin therapy typically starts with a dosage of 0.25 to 0.5 mg/day, which can be increased to a maximum dose of 20 mg per day divided into three doses, spaced about 8 hours apart. If there is no response to treatment at the initial low dose after several weeks, your doctor may gradually increase the dosage by increments of 0.125 – 0.25 mg every third day until panic disorder is controlled or until side effects make further increases undesired. The optimal therapeutic regimen is one that minimizes adverse reactions while achieving desired clinical outcomes; this often involves starting with lower dosages and slowly increasing as needed and tolerated.
What are the most common side effects for Buspar?
Side effects that are common in both Buspar (Buspirone) and Klonopin (Clonazepam) include dizziness, nausea, headache, and fatigue. But they also have unique side effects. For instance, with Buspar you may experience restlessness or feeling excited while Klonopin can cause memory problems or feelings of depression.
Further common side effects of Buspar may include:
- Dry mouth
- Sleep problems (insomnia)
- Feeling tired
- Stomach upset
Whereas for Klonopin they might be:
- Drowsiness

Are there any potential serious side effects for Buspar?
While Buspar is generally well-tolerated, it can occasionally cause serious side effects. These may include:
- Thoughts of suicide or self-harm
- Allergic reactions such as hives; difficulty breathing; swelling of the face, lips, tongue, or throat
- Visual disturbances including blurred vision and tunnel vision
- Heart complications such as fast or pounding heartbeats and chest fluttering; shortness of breath and feeling like you might faint
- Low sodium levels in the body - symptoms can include headache, confusion, slurred speech, severe weakness, vomiting, loss of coordination or unsteadiness.
On the other hand Klonopin also has some potentially serious side effects that one needs to be vigilant about:
-Serious nervous system reaction: rigid muscles causing high fever sweating confusion irregular heartbeat tremors feeling like you might pass out. -Signs pointing towards serotonin syndrome which includes agitation hallucinations fever excessive sweating shivering rapid heart rate muscle stiffness twitching loss of coordination nausea vomiting or diarrhea.
If any sign from either medication becomes apparent seek medical attention immediately.
What are the most common side effects for Klonopin?
Klonopin, a medication often used for panic disorder and certain types of seizures, can cause various side effects. Some of these include:
- Drowsiness or fatigue
- Coordination problems or unsteady walk
- Slurred speech
- Memory problems
- Depression, mood swings
- Blurry vision
- Dry mouth, sore throat
- Nausea or constipation Issues with urination such as increased frequency or urinary retention. It’s essential to remember that not everyone experiences all these side effects and they may subside over time as your body adjusts to the medication. However, if any become severe or persistently bothersome, it's crucial you consult your doctor immediately.
Are there any potential serious side effects for Klonopin?
In rare cases, Klonopin can cause serious side effects that should not be ignored. If you notice any of the following symptoms after taking Klonopin, seek immediate medical attention:
- Signs of a severe allergic reaction such as hives; difficulty breathing; swelling in your face, lips, tongue or throat
- New or worsened symptoms of depression including thoughts about suicide or self-harm
- Unusual changes in mood or behavior like panic attacks, anxiety, agitation and irritability
- Confusion and hallucinations
- Involuntary eye movements (nystagmus)
- Rapid heart rate or palpitations
- Symptoms related to dependence and withdrawal which may include seizures when abruptly stopped.
Remember to always consult with your doctor before making any changes to your medication regimen.
Contraindications for Buspar and Klonopin?
Both Buspar and Klonopin, like most anti-anxiety medications, can worsen certain symptoms of anxiety or depression in some people. If you notice an increase in your anxiety or depressive thoughts, or experience suicidal ideation while taking these medications, please reach out to a healthcare professional immediately.
Neither Buspar nor Klonopin should be taken if you are currently using, or have recently used within the past 14 days, any monoamine oxidase inhibitors (MAOIs). It's crucial to always inform your physician about all the medications you're on; MAOIs require approximately two weeks to clear from your system before starting either Buspar or Klonopin to prevent potentially dangerous drug interactions.
How much do Buspar and Klonopin cost?
For the brand name versions of these drugs:
- The price for Buspar (buspirone), a commonly prescribed medication for anxiety, varies depending on the dosage. For example, 60 tablets of Buspar at 10 mg each averages around $220, which works out to approximately $7.30/day if you are taking a typical dose.
- On the other hand, Klonopin (clonazepam) tends to be more expensive. A package containing 60 tablets at 1mg each is priced around $275 - effectively making it about $9.20 per day with typical usage.
Therefore, if you're following an average therapeutic range dosage scheme for Klonopin (i.e., up to 2 mg/day), then brand-name Buspar could be less costly on a daily treatment basis. But remember that cost should not be your primary consideration when choosing between these two medications.
As far as generic versions go:
- Generic buspirone can cost from as low as $0.16 to over $1 per pill and clonazepam's price ranges from under $0.15 to nearly $3 per tablet depending upon strength and quantity purchased.
Please note that prices may vary based on location and pharmacy used so always compare prices before purchasing your medications.
Popularity of Buspar and Klonopin
Buspirone, also known by its brand name Buspar, is an anti-anxiety drug that was prescribed to approximately 8 million people in the United States in 2020. It accounts for about 2% of all prescriptions for anti-anxiety medication. Unlike many other drugs used to treat anxiety disorders, buspirone is not a benzodiazepine and therefore does not carry the same risk of addiction or withdrawal symptoms. Its use has been steadily increasing since 2010.
On the other hand, clonazepam (brand name Klonopin) is a member of the benzodiazepine class and was prescribed to approximately 18 million people in the US in 2020. Clonazepam makes up roughly 10% of all prescriptions for anti-anxiety medications and also sees widespread use as an anticonvulsant. As with other benzodiazepines, there are significant concerns regarding dependency development with long-term usage but it remains popular due to its fast-acting relief from panic attacks and seizures. The prevalence of clonazepam prescriptions has remained relatively steady over the last decade.
Conclusion
Both Buspar (buspirone) and Klonopin (clonazepam) are used in the treatment of anxiety disorders, with a long-standing record of usage. They work differently though: Buspar acts on serotonin receptors and may take several weeks to show its effects, while Klonopin is a benzodiazepine that enhances GABA activity resulting in immediate relief from symptoms.
Buspar is considered a primary treatment for chronic anxiety disorders due to its lower risk of dependency, whereas Klonopin is typically used as an adjuvant therapy or for acute episodes of severe anxiety because it's faster-acting but has a higher potential for abuse and physical dependence.
Both medications are available as generic drugs which can result in cost savings. While buspirone may require some weeks before noticeable effects appear, clonazepam often provides immediate relief after administration.
Their side effect profiles do differ; buspirone is generally well-tolerated but might cause dizziness, nausea or headache. Clonazepam comes with risks such as cognitive impairment, withdrawal symptoms if stopped abruptly after long-term use, drowsiness and risk of dependence. Patients using either drug should keep their doctors informed about any new symptoms they experience during treatment.
