Key takeaways
Hydroxyzine (Vistaril) and clonazepam (Klonopin) are both used to treat anxiety, but they belong to different medication classes and have distinct uses and side effects. Hydroxyzine is an antihistamine that can also help with itching and allergies, while clonazepam is a benzodiazepine primarily used for seizures and panic disorder. Hydroxyzine is not a controlled substance and is available in both pill and liquid forms, whereas clonazepam is a Schedule IV controlled substance due to its potential for misuse and dependence. Clonazepam is typically taken two to three times a day and can cause side effects like drowsiness, dizziness, and poor movement control. Hydroxyzine can also cause drowsiness and dry mouth, but it is generally not recommended for long-term use due to a lack of studies on its long-term safety and effectiveness. Additionally, clonazepam should not be stopped abruptly to avoid withdrawal symptoms, while hydroxyzine does not have this issue. Both medications should be used with caution in certain populations, such as older adults and those with specific health conditions.
