Anaphylaxis to the chlorhexidine component of Instillagel®: a case series

Abstract: Anaphylaxis to chlorhexidine is rare. We report three cases of anaphylaxis attributed to the chlorhexidine component of Instillagel, presenting after urological surgery, while the patients were in the recovery room. In these cases, the cause of the collapse was not immediately obvious as the presentation was delayed. Anaesthetists should be aware that urethral lubricants may contain chlorhexidine that can trigger anaphylaxis in susceptible individuals. Anaphylaxis should be considered a possible diagnosis when… Show more

“…In these cases there is no indication of performing STs (grade of recommendation, B) [12,118,128] ii) patients with a previous history of reactions, with detailed information available regarding the reaction kinetics and drugs and agents administered. In these cases, STs are mandatory for all the agents administered plus latex [129] and clorhexidine [71,103,104,130] (grade of recommendation, C), however ST results may not be reliable until 4-6 weeks after the initial reaction [131]; iii) Patients with reactions but without clear information about the episode, which is the most complex scenario, especially when there is a long interval between the reaction and the study. In this case the type of surgery and anaesthesia and severity of the reaction can help to decide the agents to test, nevertheless it is recommended to perform ST with all the essential agents needed for anaesthesia, including a muscle relaxant derivative and an opioid (grade of recommendation, D) ( Table 3).…”

“…It has been used in clinical practice as an antiseptic since 1954 [3] and is available in aqueous or 0.5%–4.0% alcoholic solutions. Chlorhexidine has broad-spectrum activity against gram-positive and gram-negative bacteria, facultative anaerobes, yeast, and HIV [48]. …”
