Off-label medications in the treatment of hospitalized children with atopic dermatitis

INTRODUCTION: Off-label prescribing is defined as using medications outside conditions of the marketing authorisation including their licensed indications, dosage, age and route. Atopic dermatitis (AD) is the most common chronic skin condition in children which can be related to a high level of off-label prescribing. AIM: To investigate the frequency of off-label prescribing and the medications involved in relation to indications and age in paediatric patients hospitalized for atopic dermatitis in a paediatric dermatology ward in 2019. MATERIAL AND METHODS: One hundred and seventy-five consecutive discharge letters of patients were analysed regarding gender, age and medications used during hospital stay and prescribed on discharge. Each medication was checked against the licensed age and indications. RESULTS: Altogether 564 medications were prescribed, including 289 topical and 275 systemic ones with 278 prescribed off-label (49.1%). Out of 289 topical medications, 113 (39.1%) were prescribed off-label regarding indications and 34 (11.76%) regarding the age of the patients. In the systemic medications group, 96 (34.53%) were prescribed off-label as AD was not a registered indication and 35 (12.73%) as the age of the patients was outside the marketing authorization. The most frequent medications prescribed off-label were antihistamines, antibiotics and corticosteroids. CONCLUSIONS: Prescribing off-label in paediatric population is a common practice. Both topical and systemic medications are frequently used in AD patients off-label, therefore doctors should be familiar with the pitfalls of prescribing beyond the licensed indications and age.
