Antipsychotic dosing: how much but also how often?

Considerable focus has been devoted to how much antipsychotic is appropriate for optimal clinical response, although how often antipsychotics need to be administered is also less than clear. Clinicians are aware of the increased risk of relapse related to antipsychotic nonadherence/discontinuation, and current practice dictates continuous antipsychotic exposure with the goal of achieving steady state-levels to maintain effectiveness and prevent relapse. Does this mean we need to (or should) administer antipsychotics at least daily? There is a body of evidence challenging this long-established clinical axiom.
