Racial, ethnic, and biologic sex disparities in outpatient laboratory monitoring of isotretinoin use: a cross-sectional study.

Background: Isotretinoin is commonly used for the treatment of acne. Despite high efficacy, isotretinoin has a side effect profile that prompts regular outpatient laboratory monitoring. Emerging evidence suggests clinically significant lab abnormalities are rare.

A multiyear cross-sectional study of U.S. national prescribing patterns of first-generation sedating antihistamines in older adults with skin disease.

Background: First-generation antihistamines (FGAs) are classified as 'potentially inappropriate' for use in older patients (patients aged ≥ 65 years). However, the prevalence of and factors associated with FGA prescription have not been studied.

Objectives: To examine FGA prescription rates for older patients who visited dermatology offices, and compare them to those for younger patients (patients aged 18-65 years) who visited dermatology offices and those for older patients who visited primary-care physicians (PCPs).
