ABSTRACT
Patients diagnosed with schizophrenia are at least three times more likely to develop a substance use disorder than controls. These patients are frequently prescribed benzodiacepines as a coadjuvant drug, which have a high potential for addiction. We performed a literature review aiming to gather evidence on various topics concerning the use of benzodiacepines in schizophrenia, with a focus on possible abuse 1) Prevalence of prescripted and non-prescripted benzodiacepine use among patients, 2) Prevalence of abusers, 3) Effects of long-term benzodiacepine abuse in schizophrenia prognosis, 4) Possible management strategies for benzodiacepine abuse in this population. Our search revealed there is a high variability (up to 20%) in benzodiacepine abuse among patients, with cannabis and stimulants being more frequent, and no clear demographic traits have been identified among these patients. Patients with affective symptoms are more likely to abuse benzodiazepines. Its long-term effects on prognosis have been debated, with some papers hinting at a higher mortality rate. Tapering benzodiacepines has been associated with an improvement in some cognitive functions. Management strategies for potential abuse do not differ greatly for this population, and no specific pharmacological aid can be indicated, but an integral approach is proposed.
