ZYRTEC® significantly improved quality of life (QoL) in adult SAR patients*1-3
Patients receiving ZYRTEC® reported significantly greater improvements in overall RQLQ scores compared with placebo
The Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) is a validated measurement of overall QoL. These studies used the 28-item RQLQ, which measured 7 domains: activity limitation, sleep problems, nose symptoms, eye symptoms, non–hay fever symptoms, practical problems, and emotional function.†
