Hydroxyzine is primarily used as an antihistamine to relieve symptoms of allergies, such as itching, hives, and skin rashes. It is also effective in managing anxiety and tension due to its sedative properties, often prescribed to help patients feel calmer before medical procedures. Additionally, it is utilized to treat nausea, vomiting, and dizziness associated with motion sickness or certain medical conditions. In some cases, hydroxyzine is prescribed to aid in managing insomnia by promoting relaxation and sleep. Its ability to reduce itching makes it a common choice for treating eczema, dermatitis, and other skin conditions.
