Buspirone vs Xanax
Introduction
For patients struggling with anxiety disorders or symptoms, certain medications that influence particular neurotransmitters in the brain can help manage and mitigate these symptoms. Buspirone and Xanax are two such drugs commonly prescribed for anxiety conditions. They each affect different neurotransmitters in the brain but both aim to lessen anxious feelings in patients. Buspirone is an azapirone class medication that primarily targets serotonin receptors, specifically 5-HT1A, thereby affecting levels of serotonin. On the other hand, Xanax is classified as a benzodiazepine which enhances the effect of gamma-aminobutyric acid (GABA), thus reducing overall neuronal excitability throughout the nervous system.

What is Buspirone?
Buspirone (marketed under the brand name Buspar) is an anxiety medication that represents a significant advancement from the traditional class of anti-anxiety drugs known as benzodiazepines. Unlike Xanax, which falls into this earlier category and was first approved by the FDA in 1981, buspirone does not have sedative properties and poses less risk of dependency. Instead of enhancing the effect of GABA like Xanax, it primarily works by modulating serotonin levels – much like antidepressants – although its exact mechanism isn't fully understood. It's prescribed for generalized anxiety disorder and has a more selective influence on brain chemistry with fewer side effects than benzodiazepines such as Xanax, which strongly affect multiple neurotransmitters.
What conditions is Buspirone approved to treat?
Buspirone is approved for the treatment of different anxiety disorders:
- Generalized Anxiety Disorder (GAD), a condition characterized by persistent and excessive worry about various things.
- Short-term relief of symptoms of anxiety, providing temporary relief from acute symptoms of anxiety.
It's important to note that unlike Xanax, Buspirone does not belong to the benzodiazepine class of medications and therefore does not carry a risk of dependency or withdrawal.
How does Buspirone help with these illnesses?
Buspirone helps to manage anxiety by affecting the amount and activity of serotonin available in the brain. It does this by acting as an agonist on specific serotonin receptors, which means it binds to these receptors and stimulates a response that can reduce feelings of anxiety. Serotonin is a neurotransmitter, a chemical that acts as a messenger in the brain and throughout the body. It plays crucial roles in mood, cognition, memory, sleep patterns, hunger and body temperature regulation among others. Insufficient levels or imbalanced functioning of serotonin are thought to contribute significantly to anxiety disorders. Therefore, by modulating serotonin activity through its action on certain receptors - without producing substantial sedative effects like some other anti-anxiety medications (e.g., Xanax) - Buspirone can help limit symptoms associated with anxiety disorders while maintaining alertness and cognitive function.
What is Xanax?
Xanax is a brand name for alprazolam, which belongs to the benzodiazepine class of drugs. These medicines work by enhancing the effects of gamma-aminobutyric acid (GABA), a neurotransmitter in the brain that inhibits activity in the nervous system, leading to calming and soothing effects. Xanax was first approved by the FDA in 1981.
Unlike buspirone, which isn't typically associated with dependence or withdrawal symptoms, Xanax carries significant risks related to these issues due its potential for misuse and addiction. Moreover, stopping Xanax abruptly can lead to severe withdrawal symptoms if not managed properly under medical supervision.
Common side effects of Xanax include drowsiness and light-headedness. It's also worth noting that while both medications are used in treating anxiety disorders, Xanax tends to have stronger sedative properties than buspirone and is frequently prescribed for panic disorder.
What conditions is Xanax approved to treat?
Xanax has been given the green light by the FDA for treating a range of conditions, such as:
- Anxiety disorders
- Panic disorder, characterized by sudden attacks of terror often accompanied by a pounding heart, sweatiness, weakness or faintness.
- Short-term relief from symptoms of anxiety.
How does Xanax help with these illnesses?
Xanax, also known as alprazolam, is a benzodiazepine that acts on gamma-aminobutyric acid (GABA) receptors in the brain. This neurotransmitter has inhibitory effects, meaning it reduces neuronal excitation and produces a calming effect. Xanax enhances this inhibition thereby reducing anxiety significantly and quickly, which makes it an effective drug for panic disorders and acute stress reactions. Its rapid action differentiates it from buspirone which takes longer to take effect but may be preferred for long term use due to lower dependency risk. However, because of its potency and fast acting nature, Xanax can lead to dependence if used regularly over extended periods of time or abused. Therefore, while highly effective in managing symptoms of acute anxiety disorders or episodes thereof when compared with buspirone, careful monitoring is necessary when prescribing Xanax.
How effective are both Buspirone and Xanax?
Both buspirone (Buspar) and alprazolam (Xanax) are FDA-approved treatments for anxiety disorders, though they work via different mechanisms and may be prescribed under different circumstances. Buspirone acts as an agonist at the 5-HT1A receptor, a subtype of serotonin receptor, while Xanax is a short-acting benzodiazepine that enhances the effect of the neurotransmitter GABA.
In terms of clinical effectiveness, both drugs have been shown to reduce symptoms in patients with generalized anxiety disorder. However, their side-effect profiles differ significantly due to their distinct mechanisms. A review published in 2012 noted that buspirone has less potential for dependency and withdrawal compared to benzodiazepines like Xanax but can cause dizziness or nausea initially upon treatment initiation. Conversely, patients taking Xanax may experience sedation or impairment of cognitive function - factors which should be taken into consideration when prescribing this medication particularly in elderly populations who might be more sensitive to these effects.
The optimal dose varies between individuals; however generally speaking for buspirone it's typically started at 10mg twice daily and titrated up based on response whereas initial dosage for Xanax often starts from 0.25 mg given two or three times daily.
Research data directly comparing buspirone against alprazolam is limited; nonetheless studies suggest both medications could potentially serve as first-line treatments depending on individual patient characteristics including symptom severity, comorbid conditions and risk factors related to misuse/dependence.

At what dose is Buspirone typically prescribed?
Oral dosages of Buspirone range from 5–60 mg/day, but studies have indicated that 15-30 mg/day is generally sufficient for managing generalized anxiety disorder in most adults. For children and adolescents, the use and dosage should be determined by a doctor. In either population, 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.
At what dose is Xanax typically prescribed?
Xanax therapy often begins with a dosage of 0.25–0.5 mg taken three times daily. The dose may be increased to reach a maximum daily dose of 4 mg, divided into smaller doses that are spread throughout the day at intervals not exceeding 1 hour apart. An increase in dosage can be considered if there is no significant improvement in symptoms after several weeks of treatment at initial dosages. However, careful consideration should be given due to Xanax's potential for dependency and withdrawal syndrome.
What are the most common side effects for Buspirone?
The common side effects of Buspirone can include:
- Nervousness or excitement
- Headache
- Dizziness, lightheadedness
- Sleepiness/drowsiness
- Insomnia (difficulty sleeping)
- Restlessness or being unable to sit still
- Dry mouth
- Nausea, stomach upset
- Diarrhea, constipation -Tremor (uncontrolled shaking) -Sweating
On the other hand, Xanax may cause side effects such as:
-Anxiety and panic attacks
-Drowsiness, sedation
-Impaired coordination and motor functions
-Memory impairment
-Lowered libido (sex drive)
-Nausea and vomiting
-Decreased appetite
-Dry mouth
-Hypotension (low blood pressure)
-Skin rash
Both drugs can potentially lead to dependence if used over an extended period. It's important to follow your healthcare provider's instructions when using these medications.
Are there any potential serious side effects for Buspirone?
While Buspirone is generally well-tolerated, some serious side effects may occur such as:
- Unusual thoughts or behaviors, including suicidal ideation
- Signs of a severe allergic reaction, like skin rash or hives; difficulty breathing; swelling in the face, lips, tongue or throat.
- Vision changes: blurred vision or tunnel vision; eye pain and seeing halos around lights
- Heart complications: rapid heart rate, chest fluttering sensation and breathlessness. Sudden dizziness could indicate low blood pressure
- Low sodium levels manifesting as headaches, confusion and impairment in speech coherency. Severe weakness could also be noted along with vomiting episodes. Loss of coordination leading to an unsteady gait might appear.
- A significant nervous system response characterized by rigid muscles coupled with high fever. This can also present itself through sweating profusely alongside fast or uneven heartbeat patterns and tremors. The individual might feel faint resulting into loss of consciousness.
Serotonin syndrome symptoms are rare but if you experience restlessness/agitation combined with hallucinations accompanied by increased body temperature (fever), excessive sweating/shivering episodes along with rapid heartbeats it should be addressed immediately. Muscle stiffness and twitching together with impaired coordination can indicate the same too followed by gastrointestinal disturbances like nausea/vomiting/diarrhea.
If any of these symptoms appear after taking Buspirone consult your healthcare provider without delay to ensure immediate medical attention is received to manage these conditions effectively.
What are the most common side effects for Xanax?
Xanax, a commonly prescribed anxiety drug, can come with several symptoms and side effects. These include:
- Dry mouth or increased salivation
- Dizziness, light-headedness
- Tiredness/sleepiness
- Changes in sex drive/ability
- Constipation or diarrhoea
- Weight changes (loss or gain)
- Nausea/vomiting
- Increased sweating
- Difficulty breathing Confusion, memory problems, abnormal mood swings including feelings of hostility. In some cases, Xanax may cause more severe side effects such as seizures and hallucinations. It's important to consult your doctor if any unusual or persistent side effects occur while taking this medication.
Are there any potential serious side effects for Xanax?
While Xanax has been a widely used medication for anxiety, it's important to be aware of potential adverse reactions. Serious side effects could include:
- Signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat
- Depression and suicidal thoughts or tendencies
- Seizures (even if you have never had one before)
- Risk-taking behavior; decreased inhibitions; no fear of danger
- Unusual changes in mood or behavior
- Blurred vision, tunnel vision, eye pain or swelling
- Rapid heartbeats and palpitations
- Hyperactivity: feeling extremely talkative and restless
Should any such symptoms occur while using Xanax, consult with your doctor immediately.
Contraindications for Buspirone and Xanax?
Both buspirone and Xanax, along with most other anti-anxiety medications, may increase symptoms of anxiety in some people. If you notice your anxiety worsening or an increase in suicidal ideation, thoughts, or behavior while using these drugs, please seek immediate medical attention.
Neither buspirone nor Xanax should be taken if you are currently taking or have recently been on monoamine oxidase inhibitors (MAOIs). Always inform your healthcare provider about all the medications you are taking; MAOIs will require a period of about 2 weeks to clear from your system to prevent dangerous interactions with buspirone and Xanax.
How much do Buspirone and Xanax cost?
For the brand name versions of these drugs:
- The price of 60 tablets of Buspar (buspirone, 10 mg) averages around $100–$200, which works out to $1.70–$3.30/day depending on your dose.
- The price for 60 tablets of Xanax (alprazolam, 0.5 mg), is typically between $230 and $400, working out to approximately a range of $4-$7 per day.
Thus, if you're in a higher dosage range for buspirone (i.e., up to 60 mg/day), then brand-name Xanax could potentially be more expensive on a per-day treatment basis. However, cost should not be used as the primary factor when determining which medication is right for you.
In terms of generic versions:
- Generic buspirone costs are significantly lower: A pack with thirty 10mg pills can average from about $4 to $15 dollars or approximately $.07 - $.25 cents daily if taking three doses.
- Alprazolam's generic version also offers savings: Prices usually range from around $9 - $50 for sixty .5mg tablets or roughly $.15 - $.83 cents a day at two tablet dosages.
Popularity of Buspirone and Xanax
Buspirone, available in generic form as well as under the brand name Buspar, was estimated to have been prescribed to about 6.5 million people in the US in 2020. Buspirone accounted for just over 12% of anxiolytic prescriptions in the US but is not classified among benzodiazepines or other broad classes of anxiolytics. The prevalence of buspirone has been generally increasing since it was introduced due to its lower risk of dependency compared to traditional benzodiazepines.
Alprazolam, including brand versions such as Xanax, was prescribed to approximately 18 million people in the USA during 2020. In the United States, alprazolam accounts for nearly half (48%) of all benzodiazepine prescriptions and about a quarter (26%) of overall anxiolytic prescriptions. Despite growing concerns regarding potential dependency and withdrawal issues associated with long-term use, the prescription rate for alprazolam has remained steady over recent years.
Conclusion
Both Buspirone and Xanax (alprazolam) are frequently used in the management of anxiety disorders, with numerous clinical studies and meta-analyses supporting their effectiveness over placebo treatments. Occasionally, these medications may be used together under close supervision by a physician as they can interact with one another. Their mechanisms of action differ significantly; while buspirone acts as an agonist for serotonin receptors, Xanax is a benzodiazepine that enhances the effect of GABA, a natural calming agent in the brain.
Buspirone is generally preferred as first-line therapy due to its lower risk for dependency compared to Xanax which could lead to withdrawal symptoms upon discontinuation. It may be selected for patients who need long-term management of generalized anxiety disorder or those concerned about addiction potential.
Both drugs are available in generic form, offering significant cost savings especially for those paying out-of-pocket. The onset time varies between these two drugs: buspirone may require several weeks before full effects are noticed whereas Xanax often provides immediate relief from acute symptoms.
In terms of side effects profile, both medications have tolerable side effects but they differ somewhat. Buspirone rarely causes sedation unlike Xanax which commonly induces drowsiness. Patients using either medication should closely monitor their responses particularly when initiating treatment and immediately seek medical help if adverse reactions occur or if their anxiety worsens.
