What Is Hydroxyzine?

Hydroxyzine seems to be considered an antihistamine. This means that it may be able to block the effects of too much histamine. Histamine appears to build in an individual's body when they deal with an allergic reaction. It may be the cause of their symptoms. Doses of this medication may vary between patients. Considerations for dosages seem to include the patient's age, medical history, and why they are taking this medication.

It seems as if hydroxyzine is only available as a prescription antihistamine. Patients may take this common oral allergy medication when strong over-the-counter antihistamines have not worked.
