A prescription medication that is used for treating itching symptoms that are caused by anxiety and allergies is known as Generic Atarax. Allergic reactions of the skin like contact dermatitis and hives can also be treated with it. You can use the medication alone or along with other medicines recommended for anaesthesia. You can also buy Generic Atarax and use it as a sedative for treating anxiety in the short term. Sometimes doctors also prescribe it to help a patient feel relaxed or sleepy before or after their surgery.
