The half-life of Seroquel (quetiapine) is 6 hrs..

For example, if you took 10mg of Seroquel at 12AM (midnight), at 6AM 5mg of Seroquel will be left in your body. At 12PM (noon), 2.5mg will be left, and so forth until there is 0mg left in your body.

Basically that means that every 6 hours, half of the previous amount of Seroquel in the body disappears.

Some use the formula of 5x half-life. Pretty close.

How long Seroquel will take to leave your system is obviously related to dosage, your metabolism and to a lesser degree length of usage.
