Anaphylactic reaction after oral application of Wick Medinait

Case report on an anaphylactic reaction to oral polyethylene glycol (PEG) 6 000. In accordance with clinical symptoms prick skin test was positive for PEG 6000, which is contained in Wick Medinait. All other ingredients tested showed no reaction. Further skin tests revealed a positive prick test reac tion to PEG 4000. This resulted in the diagnosis of allergy to PEG 4000 and PEG 6000. Type I-allergic reactions to polyethylene glycol with longer cha in lengths are rare. Dealing with this subject, we found only three reports of contact urticaria [11, 12] and some cases of anaphylactic reactions in patients who had drunk a PEG lavage solution prior to colonoscopy [15, 22, 24, 25]. This is astonishing because PEGs are widely used.
