Key Takeaways
Valium is a benzodiazepine approved for anxiety, alcohol withdrawal, muscle spasm, and seizures, while Vistaril is an antihistamine approved for anxiety and allergic itching.
The onset of either medicine can vary with the formulation, dose, and individual; a clinician can help determine which option is appropriate for acute symptoms. Valium carries boxed warnings for dependence, misuse, and dangerous interactions with opioids.
Vistaril is not a controlled substance and is generally not associated with the physical dependence risk seen with benzodiazepines. Its FDA labeling includes anxiety and tension associated with psychoneurosis; a clinician should determine whether it is appropriate for a person's symptoms. It can prolong the QT interval and should be used cautiously in people with heart-rhythm risk factors or when combined with medicines that can affect heart rhythm.

Valium vs. Vistaril Pros and Cons
Valium
