Maintenance treatment can prevent relapses but problems with medication adherence limit effectiveness. Long-acting injectable antipsychotics (LAIs) provide an opportunity to establish adherence but challenges remain in ensuring that the dose selected is therapeutic. Therapeutic drug monitoring has not been established as valuable for LAIs in the maintenance treatment of schizophrenia.
