⭐Introduction
Drug-induced rashes are skin reactions caused by medicines. While some rashes are mild and disappear after stopping the medicine, others may become serious and need urgent medical care. Many people know about common allergic rashes, but there are also other drug-induced rashes that may appear in different forms such as redness, itching, blisters, peeling skin, or dark patches.
Understanding these rashes can help in early diagnosis and proper treatment.
