What should I watch for while using this medicine?

Visit your doctor or health care professional for regular checks on your progress. It may be several weeks before you see the full effects of this medicine. Notify your doctor or health care professional if your symptoms get worse, if you have new symptoms, if you are having an unusual effect from this medicine, or if you feel out of control, very discouraged or think you might harm yourself or others.

Do not suddenly stop taking this medicine. You may need to gradually reduce the dose. Ask your doctor or health care professional for advice.

You may get dizzy or drowsy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medicine 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.

Avoid alcoholic drinks. Alcohol can increase dizziness and drowsiness with olanzapine.

Do not treat yourself for colds, diarrhea or allergies without asking your doctor or health care professional for advice. Some ingredients can increase possible side effects.

Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water will help.

This medicine can reduce the response of your body to heat or cold. Dress warm in cold weather and stay hydrated in hot weather. If possible, avoid extreme temperatures like saunas, hot tubs, very hot or cold showers, or activities that can cause dehydration such as vigorous exercise.
