An Introduction to Quetiapine XR Dosing
The dose of
quetiapine XR (
Seroquel XR®) your healthcare provider recommends will vary depending on a number of factors, including:
- The medical condition being treated
- The severity of your condition
- Other medical conditions you may have
- Other medications you may currently be taking.
As always, do not adjust your
quetiapine XR dose unless your healthcare provider specifically instructs you to do so.

The recommended starting quetiapine XR dose for treating
schizophrenia is quetiapine XR 300 mg once daily, preferably in the evening. Generally, your healthcare provider will increase your dose quickly within a few days, up to quetiapine XR 800 mg once daily if needed.
