How Hydroxyzine works 

Hydroxyzine works by calming both the skin and the brain when your body overreacts to things like allergens or stress. For allergies, it blocks H1 histamine receptors that act like switches that turn on itching, swelling, and sneezing, keeping those reactions quiet. For anxiety or sleeplessness, it gently slows down brain signals by affecting serotonin and acetylcholine, which helps you feel more relaxed and sleepier. It doesn’t fix the root problem, but it mutes the body’s response.
