|Type of medicine||Antihistamine|
|Available as||Tablets and syrup|
Hydroxyzine is used to relieve itching of the skin due to some allergic reactions. It can be used in adults or children.
Exposure to substances such as pollen, pet fur, house dust or an insect bite, can cause the body to release a chemical called histamine. The release of histamine causes allergic symptoms which may result in an itchy rash on the skin. Hydroxyzine reduces the effects of histamine and so helps to relieve itching.
