A:

The Seroquel (quetiapine) half-life is about six hours. This means it stays in your system for about 1.5 days. Age, liver disease, and severe kidney disease can prolong the process of clearing Seroquel from the body. Do not stop Seroquel suddenly. Doctors slowly decrease the Seroquel dosage to prevent withdrawal symptoms.
