Dacomitinib significantly improves progression‐free survival and overall survival (OS) compared with gefitinib in patients with non–small‐cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR)‐activating mutations. However, dacomitinib often causes skin toxicities, resulting in treatment discontinuation. We aimed to evaluate a prophylactic strategy for skin toxicity induced by dacomitinib.
