What are olanzapine tablets?

Olanzapine is also sometimes used for the treatment of other emotional or behavioral problems like manic-depressive illness or bipolar disorder.

Tell your prescriber or health care professional about all other medicines you are taking, including non-prescription medicines, nutritional supplements, or herbal products. Also tell your prescriber or health care professional if you are a frequent user of drinks with caffeine or alcohol, if you smoke, or if you use illegal drugs. These may affect the way your medicine works. Check with your health care professional before stopping or starting any of your medicines.

What should I watch for while taking olanzapine?

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 olanzapine. Do notify your prescriber if your symptoms get worse or you have new symptoms, if you are having an unusual effect from olanzapine, or if you feel out of control, very discouraged or think you might harm yourself or others. Your prescriber can help you manage these problems.

Do not suddenly stop taking olanzapine. You may need to gradually reduce the dose. Only stop taking olanzapine on your prescriber's advice.

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

Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water will help. Be careful when brushing and flossing your teeth to avoid mouth infections or damage to your gums. See your dentist regularly. Sometimes olanzapine can make your mouth water a lot.

Olanzapine can reduce the response of your body to heat or cold. Try not to get overheated or dehydrated from exercise. Avoid temperature extremes, such as saunas, hot tubs, or very hot or cold baths or showers. Dress warmly in cold weather.

Olanzapine may make your skin more sensitive to sun or ultraviolet light. Limit your sun exposure; wear protective clothing outdoors and use a sunscreen (at least SPF 15). Avoid using sun lamps or sun tanning beds or booths.

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