Background Neurotoxins produced by the Clostridium botulinum bacterium can cause botulism in humans, usually in the foodborne or wound-based form. Less is known about botulism as a complication of medicinal or aesthetic procedures, where injections are widely viewed as safe when administered correctly. Case presentation We report on a patient with dysphagia, blurry vision, weakness in the neck, constipation, fatigue and headache after botox injections for chronic migraine, treated in a private clinic abroad 15 days before hospital admission. She was discharged with home nursing and a nasogastric tube after 10 days. Interpretation This was interpreted as the first known case of iatrogenic botulism in Norway. The diagnosis was supported by an unsure detection of free toxins in a mouse bioassay. We may see more cases related to medical tourism in the future. Antitoxins are available and should be discussed as a treatment option in iatrogenic cases.
