Vistaril has multiple uses. It reduces central nervous system activity and acts as an antihistamine. It’s often used to treat patients who are having tension and anxiety, and it does this by calming the nervous system. The antihistamine action works to help when someone is having allergy problems. When a patient has an allergy, it creates histamines in the body. This medication can cause histamines to have reduced effects in the body so that there are fewer symptoms like hives or itching on the skin.

As a sedative, it’s sometimes given to patients along with other medications during general anesthesia as well as afterward. It may also be taken by patients regularly for anxiety or on an as-needed basis when they have episodes of anxiety. It may also be prescribed for other issues like nausea or vomiting, and rashes.
