Anxiety disorders are a widespread concern, affecting millions of adults. If you’re exploring treatment options, you’ve likely come across medications like buspirone and Xanax. Both are prescribed to manage anxiety, but it’s crucial to understand their differences, especially regarding their classification. A common question arises: Is Buspirone A Benzo? The answer is no. Buspirone is not a benzodiazepine. While Xanax (alprazolam) is indeed a benzodiazepine, buspirone belongs to a different class of drugs altogether.
This article will delve into a detailed comparison of buspirone and Xanax, clarifying why buspirone is not a benzo and outlining the key distinctions between these two anti-anxiety medications. Understanding these differences is essential for making informed decisions about your mental health treatment.
Buspirone vs. Xanax: Key Differences
To clearly understand why buspirone is not a benzo, let’s break down the fundamental differences between buspirone and Xanax.
| Buspirone | Xanax | |
|---|---|---|
| Drug Class | Anti-anxiety medication (non-benzodiazepine) | Benzodiazepine |
| Brand/Generic Status | Generic only (BuSpar brand discontinued in the US) | Brand (Xanax) and generic (alprazolam) available |
| Generic Name | Buspirone | Alprazolam (Xanax is the brand name) |
| Available Forms | Oral tablet | Immediate-release tablet, extended-release tablet, orally disintegrating tablet, oral solution |
| Standard Dosage | Initial: 7.5 mg twice daily, average 20-30mg daily in divided doses | Usual range: 0.25 mg to 0.5 mg three times daily; dosage varies |
| Treatment Duration | Short-term or long-term use, as directed by a doctor | Short-term use, sometimes longer under medical supervision |
| Typical Users | Adults, Children 6+ (off-label) | Adults, Children 7+ (off-label) |
Buspirone: A Non-Benzodiazepine Approach to Anxiety
Buspirone stands out because it is not a benzodiazepine. It occupies its own unique drug class as an anti-anxiety medication. Its mechanism of action is not entirely clear, but research indicates it works by affecting serotonin and dopamine receptors in the brain. This is distinctly different from how benzodiazepines operate.
Xanax: Understanding Benzodiazepines
Xanax, on the other hand, is a well-known member of the benzodiazepine family. Benzodiazepines work by enhancing the activity of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces nerve activity in the central nervous system (CNS). This action leads to a calming, relaxing effect, which is why Xanax is effective in reducing anxiety and can also promote sleep. However, it’s important to note that Xanax is classified as a Schedule IV controlled substance due to its potential for abuse and dependence, a characteristic feature of benzodiazepines.
Uses of Buspirone and Xanax in Anxiety Treatment
Both buspirone and Xanax are primarily prescribed for managing anxiety disorders. They can provide relief from the short-term symptoms of anxiety, whether or not these symptoms are linked to depression.
Xanax also has a specific application in treating panic disorder, including panic attacks that may or may not be associated with agoraphobia.
Beyond their primary uses, both medications have been used off-label for various conditions such as alcohol withdrawal, bruxism (teeth grinding), depression, post-traumatic stress disorder, and premenstrual syndrome.
Comparing the Effectiveness of Buspirone and Xanax
Studies comparing buspirone and Xanax have shown that both can be effective in treating anxiety symptoms. However, notable differences emerge when considering side effects and tolerability.
One study directly comparing buspirone and Xanax found them to be equally effective in reducing anxiety. Importantly, buspirone was associated with fewer side effects and a lower incidence of withdrawal symptoms compared to Xanax.
Another study focused on daytime sleepiness, comparing buspirone, Xanax, and Valium (diazepam). Buspirone was found to cause the least amount of drowsiness among the three. While the difference in daytime sleepiness became less significant after the first week of treatment, those taking Xanax or Valium showed slower reaction times in performance tests. This suggests that while both can be effective, buspirone might be a better choice for individuals where maintaining daytime alertness is crucial.
Ultimately, the most suitable medication for an individual should be determined by a healthcare provider. They will consider your specific medical history, current health conditions, and any other medications you are taking to make an informed recommendation.

Food and Beverage Interactions
Both buspirone and Xanax interact with grapefruit and grapefruit juice. Consuming grapefruit products while taking these medications can lead to an increased drug level in your body, raising the risk of serious side effects.
Alcohol should be avoided when taking either buspirone or Xanax. Alcohol can amplify the side effects of both drugs, increasing impairment and potentially causing dangerous effects like slowed breathing, severe sedation, loss of consciousness, and coma.
Drug Interactions: A Critical Consideration
Before starting buspirone or Xanax, it’s vital to inform your healthcare provider about all medications you are taking, including prescriptions, over-the-counter drugs, vitamins, and supplements.
Buspirone should not be used within 14 days of taking a monoamine oxidase inhibitor (MAOI). Combining these can lead to a dangerous increase in blood pressure or serotonin syndrome, a potentially life-threatening condition.
Xanax carries a boxed warning from the FDA highlighting the serious risks of combining benzodiazepines with opioid painkillers. This combination can result in extreme sedation, severe respiratory depression, coma, and even death. If using both is unavoidable, it should be done with the lowest effective dose for the shortest duration and under close medical supervision.
The boxed warning for Xanax also emphasizes the potential for abuse, dependence, overdose, and death associated with benzodiazepines. It also warns against abrupt cessation of Xanax due to the risk of withdrawal symptoms; discontinuation should always be managed with a gradual tapering schedule under medical guidance.
| Buspirone Interactions | Xanax Interactions |
|---|---|
| Interacts with anxiety drugs | – CYP3A4 inhibitors – CYP3A4 inducers – Opioids – Alcohol – Antidepressants – Muscle relaxants – Anticonvulsants – Sedating antihistamines |
| Drug-specific interactions | – MAOIs |
Other drug interactions are possible. Always seek medical advice from your healthcare provider regarding potential interactions.

Frequently Asked Questions: Is Buspirone a Benzo and More
Are buspirone and Xanax the same type of medication?
No. While both treat anxiety, they function differently. Buspirone’s mechanism isn’t fully understood but involves serotonin and dopamine, making it distinct and not a benzo. Xanax, being a benzodiazepine, works on GABA receptors in the brain. This fundamental difference is why it’s crucial to know that buspirone is not a benzo.
Can buspirone replace Xanax?
Buspirone is not a direct substitute for Xanax in terms of being a generic equivalent, but it can be a suitable alternative for anxiety management. They operate via different pathways, with buspirone offering the benefit of less sedation. Whether buspirone is a good replacement for Xanax depends on individual needs and should be discussed with a healthcare provider.
Which is better for anxiety: buspirone or Xanax?
Clinical studies indicate that both buspirone and Xanax can be equally effective for anxiety. However, buspirone may be preferred due to causing less daytime drowsiness and having a lower risk of dependence, as buspirone is not a benzo and lacks the addictive properties associated with benzodiazepines like Xanax. The “better” medication is subjective and depends on individual patient profiles, which your doctor can assess.
Why might buspirone be chosen over a benzodiazepine like Xanax?
Buspirone often has fewer side effects compared to benzodiazepines. Crucially, buspirone is not a controlled substance because it is not a benzo. This means it carries a significantly lower risk of abuse and dependence compared to Xanax and other benzodiazepines, which are controlled substances due to their potential for addiction.
Can buspirone or Xanax be used during pregnancy?
Buspirone is classified as pregnancy category B. While animal studies suggest no fetal harm, human studies are limited. Buspirone should only be used during pregnancy if clearly necessary and under medical supervision.
Xanax is pregnancy category D, meaning it can cause fetal harm and should be avoided during pregnancy.
If you are pregnant or discover you are pregnant while taking buspirone or Xanax, consult your OB/GYN immediately.
RELATED: What medications are safe to take during pregnancy?
Is it safe to mix buspirone or Xanax with alcohol?
No. Combining buspirone or Xanax with alcohol is dangerous and potentially deadly. Both combinations can lead to severe CNS depression, respiratory depression, coma, and death. The interaction with alcohol is a significant risk factor for both types of medication, though the dependence risk is higher with Xanax as it is a benzo.
Is brand-name BuSpar still available?
No, brand-name BuSpar is no longer available in the U.S. However, generic buspirone is widely available and offers the same therapeutic benefits as the original brand.
