Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Hydroxyzine (Vistaril) and diazepam (Valium) are both medications used to treat anxiety. Hydroxyzine is an antihistamine that can also treat allergy-related symptoms. It's typically only used for short-term anxiety treatment and isn't usually a first-choice option. Diazepam is a benzodiazepine that also treats muscle spasms, seizures, and alcohol withdrawal. It's an effective anxiety treatment, but it's also a controlled substance due to its risk of dependence and misuse. Both medications can cause drowsiness and should not be mixed with alcohol.
