How does this medication work? What will it do for me?

How should I use this medication?
The usual recommended starting dose for schizophrenia is 25 mg twice daily. Quetiapine is usually started with a low dose in order to allow the body to get used to it. This dose is increased as tolerated to a target dose of 150 mg twice daily. No more than 400 mg twice daily should be taken as the safety of higher doses has not been established.
For manic episodes associated with bipolar disorder, the recommended starting dose is 50 mg twice daily. This dose is increased up to 400 mg twice daily as tolerated. Most people respond to doses between 200 mg and 400 mg twice daily.
For depressive episodes associated with bipolar disorder, the recommended starting dose is 50 mg once daily, usually at bedtime. This dose is increased to 300 mg once daily as tolerated.
