Long-acting injections of antipsychotic medication (or depots) were developed specifically to promote treatment adherence and are a valuable option for maintenance medication in psychotic illnesses. Approximately 40–60% of patients with schizophrenia are partially or totally non-adherent to their antipsychotic regimen, but only 30% or less are prescribed a long-acting injection. The use of such injections has declined in recent years after the introduction of second-generation (atypical) oral antipsychotic drugs. Research shows that possible reasons for this decline include concerns that may be based on suboptimal knowledge, as well as an erroneous assumption that one's own patient group is more adherent than those of one's colleagues. Research on attitudes has also revealed that psychiatrists feel that long-acting injections have an `image' problem. This editorial addresses the gaps in knowledge and behaviour associated with possible underutilisation of these formulations, highlighting the role of stigma and the need for more research.
