What Is Buspirone?
Buspirone is an anxiolytic medication used most often for the short-term treatment of generalized anxiety and the relief of anxiety symptoms. Unlike benzodiazepines, buspirone does not cause sedation, dependence, or withdrawal symptoms, making it a preferred option in appropriate cases[4][7][1].
- Brand names: BuSpar, BuSpar Dividose, Vanspar
- Drug class: Miscellaneous anxiolytics, sedatives, and hypnotics
- How supplied: Oral tablets in various strengths
Buspirone is not intended for immediate relief of acute anxiety and is not effective for panic disorder, severe anxiety, or as a substitute for antipsychotic medications[1][4][7].

How Buspirone Works
Buspirone interacts with neurotransmitter receptors in the brain to alter levels of serotonin and dopamine, which play a key role in mood and anxiety regulation. It is a partial agonist at the 5-HT₁A (serotonin) receptors, enhancing serotonergic activity in brain regions that modulate anxiety and fear[1].
- This mechanism is distinct from benzodiazepines and SSRIs.
- Buspirone’s effects typically develop over several weeks, not immediately after dosing.

Approved and Off-Label Uses of Buspirone
Buspirone is FDA-approved for:
- Generalized Anxiety Disorder (GAD): It alleviates excessive worry, nervousness, and tension.
- Short-term treatment of anxiety symptoms: Such as fear, irritability, dizziness, restlessness, and pounding heartbeat[4][7].
Buspirone is not intended for:
- Panic disorder
- Phobias
- Obsessive-compulsive disorder (OCD)

Off-label uses are sometimes considered by physicians for depression as a second-line agent, but such use is less common and not strongly supported by controlled studies[1].

Dosage, Administration, and Precautions
Buspirone is usually prescribed at a low starting dose, with gradual increases based on individual response.
- Typical starting dose: 7.5 mg twice daily
- Maximum dose: 60 mg per day, split across 2-3 doses[2][5][8]
- Consistency: Take buspirone either always with food or always without food, as food increases its bioavailability[2][5]
- Adjustments: Dose changes should be made at intervals of at least 2-3 days[4][8]
Precautions:
- Do not take buspirone with MAO inhibitors or within 14 days of stopping an MAOI.
- Caution is advised in patients with liver or kidney impairment.
- Not approved for use in individuals under 18 years old, though sometimes used off-label with specialist supervision[7].
