Summary
This study aimed to see if a combination of levocetirizine (an antihistamine) and pseudoephedrine (a decongestant) works better than levocetirizine alone for relieving nasal congestion in people with allergic rhinitis. It was designed for participants aged 12 to 65. However, the study was withdrawn before enrolling anyone, so no results are available.
