Epidermal growth factor receptor
Epidermal growth factor receptor (EGFR) inhibitors are medications used in cancer treatment. These medications commonly cause skin and nail problems, including rashes, dry skin and paronychia. Preventive intensive moisturising with emollient ointments several times, avoidance of water-based creams and water soaks (although in certain circumstances white vinegar or potassium permanganate soaks may help), protection the skin from excessive exposure to sunshine, and soap substitutes which are less dehydrating for the skin than normal soaps, as well as shampoos that reduce the risk of scalp folliculitis, are recommended. Treatment measures with topical antibiotic medication can be helpful.
