Depends: The opening depends on the patency at the nasopharyngeal area. Antihistamines by mouth do not decongest the nasopharyngeal area although nasal steroid if aimed laterally often does. The optimal decongesting effect from nasal steroid is at 5-7 day of daily use. If the problem persists, consult an allergist.
