title: Risperidone long-acting injections: successful alternative deltoid muscle injections for refractory schizophrenia.
abstract: Treatment-resistant paranoid schizophrenia is often addressed with long-term intramuscular preparations of conventional antipsychotics (haloperidol and fluphenazine), which can be associated with the development of painful, lumpy nodules at the injection site. In this article, we present a case example of a 58-year-old male patient with paranoid schizophrenia who was treated with risperidone long-acting injection given into the deltoid muscle instead of the US Food and Drug Administration (FDA)-approved gluteal muscle injection site. Use of this agent in the deltoid muscle facilitated healing of the numerous painful lumpy nodules associated with prior trials of conventional long-acting injections. In addition, the patient's psychiatric outcome was improved relative to what had been observed with the previous agents.
