Atarax Product Information
Hydroxyzine is a first-generation antihistamine primarily used to manage anxiety and tension associated with nervous and emotional conditions. It is also effective in controlling anxiety and inducing sleep prior to surgical procedures. Additionally, hydroxyzine is prescribed to alleviate symptoms of allergic conditions, including chronic urticaria, atopic dermatitis, and contact dermatoses.
The medication works by blocking the action of histamine, a natural substance in the body responsible for allergic symptoms. It also exerts a sedative effect by decreasing activity in the brain.
