Vistaril Oral

A healthcare provider may prescribe Vistaril® (hydroxyzine) to treat several conditions, such as nausea, vomiting, and allergic reactions caused by opioid medications. This medication is approved for use in adults and children.
Vistaril is available in the form of capsules, an oral suspension (liquid), and an injection. It is typically taken two to four times a day.
As a type of antihistamine, Vistaril works for allergic reactions (or itching reactions to opioids) by blocking histamine receptors. It probably works for anxiety by affecting certain parts of the brain. Vistaril also can cause relaxation of skeletal muscles and blocks acetylcholine receptors (which is probably why it helps to alleviate nausea).
Oral Vistaril capsules and suspension come in various strengths, including:
The injectable form of Vistaril is available in two strengths.
