There are several synonyms for the term "drug rash", which is a skin reaction caused by a medication. Some of the other terms used to describe this condition include medication-induced rash, drug-induced dermatitis, and drug-related erythema. These terms are often used interchangeably and refer to the same skin condition. The symptoms typically include redness, itching, and small bumps on the skin, which can be mild or severe. Treatment may involve discontinuing the medication that caused the rash, taking antihistamines or applying topical creams to reduce itching and inflammation. It is important to consult with a healthcare professional if you experience a drug rash to determine the cause and appropriate treatment.
