Chlorhexidine is used as an antiseptic and disinfectant agent because of its wide antimicrobial spectrum. Immediate hypersensitivity reactions to chlorhexidine have rarely been reported in the literature [1]. One case of contact urticaria caused by chlorhexidine has been reported following dermal exposure to a hydroalcoholic gel.

A 45-year-old female with obsessive–compulsive disorder presented with an acute itchy eruption on the neck and cleavage, which appeared five days earlier, ten minutes after the frictional application of a hydroalcoholic gel to prevent a COVID-19 infection. The patient presented urticarial lesions with annular erythematous wheals on the neck and cleavage and extending to the submammary area. Brownish scales were also present, indicating the beginning of skin healing after the chemical burn (Figs. 13). There were neither angioedema nor respiratory symptoms. She reported a similar eruption located initially on the hands and forearms after the first application of the hydroalcoholic gel, which resolved spontaneously in several hours. She had never used any product containing chlorhexidine before and had no history of allergic reactions. Contact urticaria to the hydroalcoholic gel was suspected. The patient was treated with cetirizine at a dose of 10 mg once daily and scar creams, with a rapid resolution of the skin lesions.
