Elidel® is indicated for the short-term treatment and long-term management of signs and symptoms of atopic dermatitis (AD) in infants (3 to 23 months), children (2 to 11 years), adolescents (12 to 17 years), and adults. However, little evidence is available in literature in South and East Asian population. Hence, this non interventional study (NIS) is designed to capture data about the actual use of Elidel® in South and East Asian patients from 3 months to 12 years with mild to moderate AD.

Once the clinical decision has been made to prescribe Elidel® to a patient according to the local Package Insert, the investigator will consider recruiting the patient into this NIS. The decision to prescribe Elidel® must be prior to and independent from the decision to include the patient into the NIS.

As per study design:

• Visit 1 (V1; Inclusion): Only after the decision of prescribing Elidel® has been made, eligible patients will be asked for their agreement to participate in the study.
• V1a/b/c (optional visits): AD related visits between Inclusion and Elidel® Treatment Interruption - according to routine clinical practice
• Visit 2 (V2; Elidel® Treatment Interruption): Investigators will decide to interrupt Elidel® treatment because of success or failure: Treatment success: Patient's symptoms improved and does not need to continue the Elidel® treatment. Treatment failure: Patient's symptoms worsened and need to switch to a different treatment.
• V2a/b/c (optional visits): AD related follow-up visits between Elidel® Treatment Interruption and EOS - According to routine clinical practice.
• Visit 3 (V3; End of Study): The study ends after the Maintenance Period of at least 3 months allowing certain flexibility to respond to the routine practice.

End of Study will be approximately 6 months after the inclusion depending on length of the Elidel® Treatment Period. Collection of data includes but not limited to patients' demographics, clinical history, clinical symptom and manifestation, comorbidities, reported adverse events and concomitant medications. The patients' questionnaires (IDQOL and CDLQI) will be utilized to collect data directly from enrolled patients and transferred into the CRF.
