Hydroxyzine comes under the category of antihistamines. Having both, sedative and anticholinergic properties, it is therefore used in the treatment of allergic reactions. It follows a strategy for curing allergic reactions. When histamine attaches to the receptors present on the surface of cells, it stimulates them to release certain chemical messengers. This causes sneezing, itching, and a rise in mucus production. Antihistamines resemble histamines in structure. They bind to the histamine receptors on the cell surface, and thus prevent the attachment of histamines with the cells. This further prevents the occurrence of allergic reactions in your body. Consumption of hydroxyzine as a medicine is generally considered to be safe, and does not cause any negative reactions. However, medical professionals do not deny the possibility of certain side effects. These generally occur in cases of overdose or wrong dosage and also, when the person naturally has allergy against hydroxyzine and any of its constituents.
