What is the half life of seroquel (quetiapine) xr?

Seroquel (quetiapine) XR 1/2 life: Elimination of quetiapine is mainly via hepatic metabolism. The mean-terminal half-life is approximately 7 hours for quetiapine and approximately 12 hours for norquetiapine within the clinical dose range. Steady-state concentrations are expected to be achieved within two days of dosing. XR allows faster uptitration. It should be taken with food. Best regards.

Seroquel (quetiapine) XR: Seroquel (quetiapine) xr can work well for schizophrenia, bipolar, bipolar depression and adjunctive depression treatment. It can cause sedation so it is typically given a few hours before bedtime. I sometimes say take it at 7pm to be up by 7 am. It is similar to seroquel (quetiapine) (not xr) which is now generic. For some individuals it can cause weight gain. Discuss any concerns with your doctor.
