Second-generation long-acting injectable antipsychotics: A practical guide

Risperidone LAI. When increasing the dose of risperidone LAI, do not expect to see the clinical effects of the new dose earlier than 3 weeks after initiating the higher dose, because the main release of the medication starts at 3 weeks after the injection.¹

Risperidone LAI for SQ has specific recommendations for the LAI dose based on whether the patient was stable when receiving 3 or 4 mg/d of oral risperidone. If patients are stable on <3 or >4 mg/d, they may not be candidates for risperidone LAI for SQ.⁷

Table 6^1-7,10 lists additional factors to consider when prescribing a specific LAIA.

Bottom Line

Second-generation long-acting injectable antipsychotics (LAIAs) have the potential to increase medication adherence. There are important differences among the 7 currently available LAIAs. For effective prescribing, clinicians need to understand each medication’s unique aspects, including dosing options, frequency, need for oral antipsychotic overlap, and route of administration.
