Modafinil in schizophrenia: is the risk worth taking?

Schizophrenia is a severe mental disorder characterised by positive and negative symptoms. Negative symptoms are difficult to treat and there is no specific treatment. In small trials, modafinil has been studied in association with antipsychotic treatment. We present three cases of its use; two have developed positive symptoms and one developed renal impairment. Further studies are needed to assess its usefulness in schizophrenia and safety in this group of patients. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.
