What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With Serious Adverse Events (SAEs) and Non-serious Adverse Events (AEs)	A non-serious AE is defined as any untoward medical occurrence in a participant/clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. For marketed medicinal products, this also includes failure to produce expected benefits (i.e., lack of efficacy), abuse, or misuse. An SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, is a congenital anomaly/birth defect, or is a possible drug-induced liver injury. For a list of all SAEs/non-serious AEs occurring at a frequency of >=5%, please see the SAE/non-serious AE module of this record.	up to Week 2/Early Withdrawal (EW)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants With the Indicated Change From the First Day of Treatment in Allergic Rhinitis and Pruritis Associated With Skin Diseases at Weeks 1 and 2/EW, as Assessed by the Investigator/Sub-investigator Based on Legal Representative Impression	The investigator or sub-investigator made an overall assessment of nasal symptoms (allergic rhinitis [AR]) and pruritus associated with skin diseases (PAWSD) at Weeks 1 and 2 (or at the discontinuation day in the case of early withdrawal [EW] from the clinical trial) by asking the participants' legal representatives to provide feedback using the following scale: 1, significantly improved; 2, moderately improved; 3, mildly improved; 4, no change; 5, mildly worse; 6, moderately worse; 7, significantly worse. Only those participants with AR and PAWSD at Baseline were assessed for improvement in the conditions at Weeks 1 and 2. The "n"s in the category titles reflect the number of participants in the Full Analysis Set (FAS) who had AR and PAWSD at Baseline.	First day of treatment; Weeks 1 and 2/Early Withdrawal
Number of Participants With the Indicated Change From the First Day of Treatment in Nasal Symptoms and Pruritis Associated With Skin Diseases at Weeks 1 and 2/Early Withdrawal, as Assessed by the Investigator or Sub-investigator	The investigator or sub-investigator comprehensively assessed the participants' improvement in nasal symptoms (allergic rhinitis [AR]) and pruritus associated with skin diseases (PAWSD) at Weeks 1 and 2 (or at the discontinuation day in the case of early withdrawal [EW] from the clinical trial) compared to the first day of treatment by using the following scale: 1, markedly improved; 2, moderately improved; 3, slightly improved; 4, no change; 5, worsened.	First day of treatment; Weeks 1 and 2/Early Withdrawal
Number of Participants Categorized With the Indicated Pruritis Severity on the First Day of Treatment and at Weeks 1 and 2/Early Withdrawal	The investigator comprehensively assessed the pariticipant's severity of pruritus on the first day of treatment (FDOT), at Week 1, and at Week 2 (or at the discontinuation day in the case of early withdrawal [EW] from the clinical trial) by using the following scale: 4, severe; 3, moderate; 2, mild; 1, slight; 0, none.	First day of treatment; Weeks 1 and 2/Early Withdrawal
Cmax and Cmin of Levocetirizine in Plasma	Cmax is defined as the peak plasma concentration of a drug after administration. Cmin is defined as the lowest (trough) concentration that a drug reaches before the next dose is administered. For both age cohorts, blood samples were collected 1.5-2.5 hours after the last drug administration for assessment of Cmax at either Week 1 or 2/EW. For participants in the >=6 months and <12 months cohort, blood samples were collected 22.5-25.5 hours after the last drug administration for Cmin at a different visit from Cmax sampling. For participants in the >=12 months and <24 months cohort, blood samples were collected 10.5-13.5 hours after the final drug administration for Cmin at a different visit from Cmax sampling. For all participants, if Cmin sampling occurred at Week 1, then Cmax sampling occurred at Week 2/EW, and vice versa.	Weeks 1 and 2/Early Withdrawal
