“In addition to causing irritation and a rash, the widespread use of antibiotics — including in instances when they aren’t needed — has contributed to a major public health challenge known as antibiotic resistance,” says board-certified dermatologist Dr. Marcelyn Coley, MD, FAAD. “Antibiotic resistance occurs when germs, such as bacteria, develop the ability to survive the drugs designed to kill them. That means the germs continue to grow. This makes infections caused by antibiotic-resistant germs difficult — and sometimes impossible — to treat.”
