Non-suicidal self-injury by intravenous application of nicotine in a patient with borderline personality disorder resulting in substance dependence.

Abstract

Non-suicidal self-injury in many different forms is a classic struggle for those diagnosed with borderline personality disorder (BPD). Some common ways of NSSI are cutting, scratching and head-banging. A 23-year old woman with BPD presented in our clinic with a 4-month history of intravenous application of a liquid dosage form of nicotine that is generally used for nasal application. Accordingly, the patient developed nicotine dependency (ICD-10 F17.25). Before her admission to our ward the daily intravenous nicotine application was around 33 mg. The in-patient detoxification proceeded without a remarkable withdrawal syndrome. A case of regular intravenous administration of nicotine has been observed, apparently resulting in nicotine dependence in a person with borderline personality disorder. The original intent appears to have been self-harm.
