The use of academic detailing to improve evidence based prescribing of risperidone long acting injection.

Objective. It takes 6 weeks for plasma levels of risperidone long-acting injection (RLAI) to reach steady state, and randomised controlled trials demonstrate a flat dose-response curve. In clinical practice, the dose of RLAI is often increased rapidly at the start of treatment and many patients receive a dose above 25 mg/2 weeks.
