'''Red man syndrome''' (RMS) is a [[hypersensitivity]] reaction commonly associated with the administration of the [[antibiotic]] [[vancomycin]]. It is characterized by flushing, rash, and pruritus that primarily affects the face, neck, and upper torso, hence the name "Red man syndrome".

==Etiology==

Red man syndrome is not a true [[allergic reaction]], but rather a direct result of [[histamine]] release from [[mast cells]]. This reaction is most commonly associated with the rapid intravenous administration of vancomycin. Other drugs, such as [[ciprofloxacin]], [[amphotericin B]], and [[rifampicin]], have also been reported to cause RMS.

==Clinical Presentation==

The symptoms of Red man syndrome typically occur within 4 to 10 minutes after the start of a vancomycin infusion. The most common symptoms include flushing, rash, and pruritus, primarily affecting the face, neck, and upper torso. Other symptoms may include [[hypotension]], [[tachycardia]], [[dyspnea]], [[nausea]], and [[chills]].

==Diagnosis==

The diagnosis of Red man syndrome is primarily clinical, based on the characteristic symptoms and their temporal relationship to drug administration. There are no specific laboratory tests for RMS. However, [[differential diagnosis]] should be made to rule out other conditions such as [[anaphylaxis]] and [[drug eruption]].

==Management==

The primary management of Red man syndrome involves stopping the infusion of vancomycin and providing supportive care. Antihistamines, such as [[diphenhydramine]], can be used to alleviate symptoms. Once the symptoms have resolved, vancomycin can be restarted at a slower rate.

==Prevention==

Prevention of Red man syndrome primarily involves the slow administration of vancomycin over at least 60 minutes. Pre-treatment with antihistamines may also be beneficial in patients who have previously experienced RMS.
