Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Chlordiazepoxide (Librium) and alprazolam (Xanax) are both benzodiazepines used to treat anxiety, but they have some key differences. Chlordiazepoxide is used for short-term relief of anxiety symptoms and alcohol withdrawal, while alprazolam is approved for generalized anxiety disorder (GAD) and panic disorder. Chlordiazepoxide takes up to 4 hours to reach maximum levels in your blood and can stay in your system for over 10 days, whereas alprazolam starts working within 30 minutes and typically clears out in 2-3 days. Both medications are available as lower-cost generics, while alprazolam is available in both immediate-release and extended-release forms. Both medications can cause drowsiness and confusion, but alprazolam has a higher incidence of memory problems and other side effects like irritability and appetite changes. Both should be used short-term due to the risk of addiction and withdrawal symptoms, and neither is recommended during pregnancy.
