Description
Hydroxyzine belongs to the class of medications called antihistamines. It is used to relieve itching and other symptoms caused by allergic conditions. It can help to alleviate itching due to an adverse reaction to opioid medications. It works by blocking the actions of one of the body’s natural chemicals known as histamine. Histamine is responsible for many of the symptoms seen when an allergic reaction occurs. The calming effects of hydroxyzine result from its sedating side effect.
It is also used to manage anxiety and tension caused by situations such as dental procedures or acute emotional problems. Hydroxyzine is also used to control nausea and vomiting (except in pregnancy).
For adults and children weighing more than 40 kg, the recommended dose of hydroxyzine when taken by mouth is up to a maximum of 100 mg per day, divided into 3 or 4 doses. For people over the age of 65 years, the maximum daily dose is 50 mg.
For children weighing less than 40 kg, the dose is based on body size, and is calculated as 2 mg per kilogram of body weight. This dose is then divided into 3 or 4 doses to be taken spaced out throughout the day. The maximum daily dose of hydroxyzine for this group is 80 mg per day.
