Dizziness, drowsiness, diarrhea, dry mouth, constipation, increased appetite, weight gain, or trouble sleeping may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor immediately if any of these unlikely but serious side effects occur: unusual or severe mental/mood changes (e.g., confusion, nervousness, trouble concentrating, rare thoughts of suicide), swelling hands/ankles/feet, restlessness, shaking (tremor), inability to keep still, decreased interest in sex, changes in sexual ability, large pupils, trouble urinating.
Tell your doctor immediately if any of these rare but very serious side effects occur: black stools, vomit that looks like coffee grounds, easy bruising/bleeding, muscle spasm, yellowing eyes/skin, severe stomach/abdominal pain, slow heartbeat, signs of infection (such as fever, persistent sore throat).
Get medical help right away if any of these rare but serious side effects occur: fainting, severe headache, seizures.
This drug may infrequently make your blood sugar level rise, an effect that may cause or worsen diabetes. This high blood sugar can rarely cause serious conditions such as diabetic coma. Tell your doctor immediately if you develop symptoms of high blood sugar, such as increased thirst/urination or unexplained weakness. If you already have diabetes, be sure to check your blood sugars regularly and share the results with your doctor. Your doctor may need to adjust your medication, diet, and exercise program when you start or stop this medication.
This drug may also cause significant weight gain and a rise in your blood cholesterol (or triglyceride) levels, especially in teenagers. These effects, along with diabetes, may increase your risk for developing heart disease. Discuss the risks and benefits of treatment with your doctor. (See also Notes section.)
This medication may increase serotonin and rarely cause a very serious condition called serotonin syndrome/toxicity. The risk increases if you are also taking other drugs that increase serotonin, so tell your doctor or pharmacist of all the drugs you take (see Drug Interactions section). Get medical help right away if you develop some of the following symptoms: fast heartbeat, hallucinations, loss of coordination, severe dizziness, severe nausea/vomiting/diarrhea, twitching muscles, unexplained fever, unusual agitation/restlessness.
This medication may rarely cause a very serious condition called neuroleptic malignant syndrome (NMS). Get medical help right away if you have any of the following symptoms: fever, muscle stiffness/pain/tenderness/weakness, severe tiredness, severe confusion, sweating, fast/irregular heartbeat, dark urine, change in the amount of urine.
Olanzapine may rarely cause a condition known as tardive dyskinesia. In some cases, this condition may be permanent. Tell your doctor immediately if you develop any unusual/uncontrolled movements (especially of the face/lips/tongue).
In rare cases, this medication may increase your blood level of a certain hormone (prolactin). For females, this rare increase in prolactin levels may result in unwanted breast milk, irregular/stopped menstrual periods, or difficulty becoming pregnant. For males, it may result in decreased sexual ability, inability to produce sperm, or enlarged breasts. If you develop any of these symptoms, tell your doctor immediately.
For males, in the very unlikely event you have a painful or prolonged erection lasting 4 or more hours, stop using this drug and seek immediate medical attention, or permanent problems could occur.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.
This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

PRECAUTIONS: Before taking olanzapine/fluoxetine, tell your doctor or pharmacist if you are allergic to olanzapine or fluoxetine; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: personal or family history of suicide attempts, breast cancer, intestinal problems (e.g., paralytic ileus, chronic constipation), kidney disease, liver problems, low blood pressure, neuroleptic malignant syndrome, narrow-angle glaucoma, prostate problems, seizures, stomach/intestinal ulcers, brain problems (e.g., dementia, stroke), severe loss of body water (dehydration), low white blood cell count.
Also tell your doctor or pharmacist if either you or a family member has a history of the following: diabetes, heart disease (e.g., chest pain, heart attack, heart failure, irregular heartbeat), high blood cholesterol/triglyceride levels, high blood pressure, obesity.
This drug may make you dizzy or drowsy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely. Avoid alcoholic beverages.
To reduce dizziness and lightheadedness, get up slowly when rising from a sitting or lying position, especially when you first start taking this medication.
Fluoxetine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can infrequently result in serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using olanzapine/fluoxetine, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using this medication safely.
This medication can make it harder to control your body temperature. Avoid activities that might cause you to overheat (e.g., doing strenuous work, exercising in hot weather, or using hot tubs). Drink plenty of fluids to avoid becoming dehydrated.
Teenagers may be more sensitive to the side effects of this drug, especially weight gain, and also increased amounts of cholesterol, triglycerides and prolactin. See also Side Effects section for more details.
Older adults may be more sensitive to the side effects of this drug, especially QT prolongation (see above), drowsiness, constipation, trouble urinating, confusion, or dizziness upon standing. Older adults may also be more likely to develop low sodium in the blood, especially if they are taking "water pills" (diuretics). Drowsiness, confusion, and dizziness can increase the risk of falling.
During pregnancy, this medication should be used only when clearly needed. It may harm an unborn baby. Also, babies born to mothers who have used this drug during the last 3 months of pregnancy may infrequently develop symptoms including muscle stiffness or shakiness, drowsiness, feeding/breathing difficulties, or constant crying. If you notice any of these symptoms in your newborn anytime during their first month, tell the doctor right away.
Since untreated depression can be a serious condition, do not stop taking this medication unless directed by your doctor. If you are planning pregnancy, become pregnant, or think you may be pregnant, immediately discuss the benefits and risks of using this medication during pregnancy with your doctor.
