Summary
This study was designed to see if a combination of levocetirizine (an allergy medicine) and pseudoephedrine (a decongestant) works better than levocetirizine alone for relieving nasal congestion in people with allergic rhinitis. It planned to enroll people aged 12 to 65 with the condition. However, the study was withdrawn before any participants were enrolled.
