What You'll Learn

Hydroxyzine is the generic form of Vistaril
Hydroxyzine, also known by its brand name Vistaril, is an antihistamine medication. It is used to treat anxiety and tension caused by nervous and emotional conditions. It can also be used to help control anxiety and produce sleep before surgery. Hydroxyzine is also used to treat difficulty sleeping, nausea, vomiting, itching, skin rash, and allergies. It is available in the form of capsules, tablets, syrup, and solution. The dose of hydroxyzine will differ for each patient, but adults are typically prescribed 50 to 100 milligrams (mg) 4 times a day.
Hydroxyzine is not a controlled substance, meaning it does not have the risk of addiction associated with other medications used to treat anxiety, such as lorazepam (Ativan®), alprazolam (Xanax®), and clonazepam (Klonopin®). However, it is important to note that hydroxyzine should not be used as a long-term daily solution for anxiety or sleep for most people. Tolerance to the medication can build over time, reducing its effectiveness.
Hydroxyzine may be taken with or without food. However, if it causes an upset stomach, it is recommended to take it with food. It can be taken daily at regular times or on an as-needed ("PRN") basis, depending on the advice of your healthcare provider. They will determine the appropriate dose and method of taking the medication based on your response.
Hydroxyzine can cause drowsiness, so caution should be exercised when driving or operating heavy machinery after taking it. Additionally, it may interact with other central nervous system (CNS) depressants, such as narcotics, non-narcotic analgesics, and barbiturates. Therefore, it is important to consult a doctor before taking hydroxyzine with other medications.
