What should I watch for while taking quetiapine?

Visit your prescriber or health care professional for regular checks on your progress. It may be several weeks before you see the full effects of quetiapine. Do not suddenly stop taking quetiapine. You may need to gradually reduce the dose. Only stop taking quetiapine on your prescriber's advice.

Your health care provider may suggest that you have your eyes examined prior to starting quetiapine, and every 6 months thereafter.

You may get dizzy or drowsy. Do not drive, use machinery, or do anything that needs mental alertness until you know how quetiapine affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can increase dizziness and drowsiness. Avoid alcoholic drinks.

Do not treat yourself for colds, diarrhea or allergies. Ask your prescriber or health care professional for advice, some nonprescription medicines may increase possible side effects.

If you are going to have surgery tell your prescriber or health care professional that you are taking quetiapine.

Where can I keep my medicine?

Keep out of the reach of children in a container that small children cannot open.
