Buspirone vs Xanax: A Comparison

Buspirone and Xanax are two drugs that are used to treat anxiety disorders. While they are both used to treat the same conditions, they work in different ways and have different benefits and drawbacks. In this article, we will compare and contrast these two drugs.

Mechanism of Action

Buspirone and Xanax have different mechanisms of action. Buspirone works by affecting serotonin receptors in the brain, which leads to a decrease in anxiety symptoms. Xanax, on the other hand, works by increasing the activity of GABA, which is an inhibitory neurotransmitter. This leads to a decrease in anxiety symptoms as well as muscle relaxation and sedation.


Both buspirone and Xanax are used to treat anxiety disorders, but they are approved for different types of anxiety. Buspirone is mainly used to treat generalized anxiety disorder, while Xanax is used to treat a variety of anxiety disorders, including panic disorder, social anxiety disorder, and generalized anxiety disorder.

Onset and Duration of Action

Buspirone has a slower onset of action compared to Xanax. It can take several weeks for the full effects of buspirone to be felt, while Xanax begins to work within an hour of taking it. The duration of action for buspirone is longer than Xanax, with effects lasting up to 12 hours, while Xanax’s effects usually last 4-6 hours.

Side Effects

Both buspirone and Xanax can cause side effects. Some common side effects of buspirone include dizziness, nausea, headache, and nervousness. Xanax can cause drowsiness, dizziness, and coordination problems. Xanax is also more likely to cause addiction and dependence compared to buspirone.


Buspirone and Xanax are both effective drugs for treating anxiety disorders, but they have different mechanisms of action, indications, onset and duration of action, and side effects. While Xanax may work faster, it is more likely to cause addiction and dependence, making buspirone a safer long-term option for many patients.
