      based on cross-study comparison of the plasma concentration of desloratadine in
      adults and pediatric subjects. The safety of desloratadine oral solution has been
      established in 246 pediatric subjects aged 6 months to 11 years in three placebo-
      controlled clinical studies.

    - In general, dose selection for an elderly patient should be cautious, reflecting
      the greater frequency of decreased hepatic, renal, or cardiac function, and of
      concomitant disease or other drug therapy. [See CLINICAL PHARMACOLOGY ( 12.3 )].
      8.6 Renal Impairment Dosage adjustment for patients with renal impairment is
      recommended [see DOSAGE AND ADMINISTRATION ( 2.5 ) and CLINICAL PHARMACOLOGY (

      desloratadine and its metabolite approximately 320 times that at the recommended
      human daily oral dose (RHD) of 5 mg/day.
