Allergic rhinitis is a chronic respiratory disease characterized by inflammation of the nasal cavity and affects people of all ages. The main symptoms of allergic rhinitis are sneezing, nasal itching, blocked or runny nose and sore throat (NHS, 2012; WHO, 2013). Research suggests that a combination of genetic factors such as family history of allergic rhinitis and environmental factors such as exposure to allergens, including smoke, dust, pollen, insects, molds, or animal dander, may increase the risk for developing allergic rhinitis (NHS, 2012; WHO, 2013). In the seven major markets (7MM) (US, France, Germany, Italy, Spain, UK, and Japan), the prevalence of self-reported allergic rhinitis ranges from 13.7% in men and 14.3% in women in the US to 35.1% in men and 39.3% in women in Japan (Bauchau and Durham, 2004; Konno et al., 2012; Nathan et al., 1997; Ozdoganoglu and Songu, 2012). According to the World Health Organization (WHO), an estimated 400 million people worldwide were affected with allergic rhinitis during 1996–2006 (WHO, 2007).
