Hydroxyzine works by inhibiting the action of histamine, a substance in the body that causes allergic symptoms like itching, swelling, and rashes. In addition to its antihistaminic effects, hydroxyzine exhibits significant sedative effects, likely through its action on specific neurotransmitters in the brain involved in anxiety and wakefulness.

SKU: N/A Category:


Hydroxyzine, known by the brand names Vistaril and Atarax, is a medication primarily used to treat itching caused by allergies, induce sedation before or after general anesthesia, and treat anxiety. Belonging to a class of medications known as antihistamines, hydroxyzine blocks the activity of histamine in the body and also has anxiolytic (anxiety-reducing) and sedative effects. This dual functionality makes it effective in managing allergic reactions and providing sedation.
