Hydroxyzine Pamoate Basics
Hydroxyzine pamoate is available by prescription only. Hydroxyzine pamoate is an antihistamine that blocks the effects of histamines in the body. Hydroxyzine pamoate also depresses the activity of the central nervous system. Hydroxyzine pamoate reduces or prevents swelling, itchiness, hives, rashes, anxiety disorders, and tension in stressful situations. Hydroxyzine pamoate binds to H1 receptors, a type of histamine receptor, that affect small blood vessels and smooth muscles. When histamines bind to H1 receptors, it causes blood vessels to dilate, and fluid begins to leak out, causing swelling and itchiness. Hydroxyzine pamoate prevents histamines from binding to receptors.
