What is the most commonly prescribed medication in the United States for anxiety?

Benzodiazepines are commonly prescribed medications for anxiety in the United States due to their effectiveness in quickly reducing symptoms of anxiety. These medications work by enhancing the effect of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain, leading to a calming effect on the central nervous system. They are often used in both short-term and long-term treatment plans, depending on the severity of the anxiety and the needs of the patient.

While antidepressants can also be effective for anxiety disorders, particularly selective serotonin reuptake inhibitors (SSRIs), they typically take longer to show results compared to benzodiazepines. Barbiturates, on the other hand, are less commonly prescribed today due to their potential for addiction and overdose, and stimulants are primarily used to treat attention deficit hyperactivity disorder (ADHD) rather than anxiety. Therefore, benzodiazepines remain the most frequently prescribed class of medication for anxiety management in clinical practice.
