Compare Valium vs. Chlordiazepoxide

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Diazepam (Valium) and chlordiazepoxide (Librium) are both benzodiazepines used to treat anxiety and alcohol withdrawal symptoms. Diazepam is available as a tablet and liquid solution, while chlordiazepoxide comes as a capsule. Diazepam works by increasing levels of gamma-aminobutyric acid (GABA) in the brain, which helps control anxiety, muscle spasms, and seizures. On the other hand, researchers aren't exactly sure how chlordiazepoxide works, but it's thought to slow down brain activity to manage anxiety and alcohol withdrawal symptoms. Diazepam typically starts working within 15 to 30 minutes, whereas chlordiazepoxide can take up to 4 hours to reach maximum levels in your blood. Both medications carry a risk of addiction and dependence, and they should be used for the shortest time possible. Both medications are not recommended during pregnancy or breastfeeding. Common side effects for both include drowsiness, dizziness, and confusion.
