Let's take a minute to talk about your medication.

This is olanzapine. You may also hear it called by its brand name, Zyprexa. It helps to treat schizophrenia and bipolar disorder. When used in combination with fluoxetine, it also helps to treat certain types of depression. It may have other uses, too.
It is often taken once each day, at the same time. You should take Olanzapine exactly how your doctor tells you to. You can take your dose with or without food. Your healthcare team will work to determine the best dose for you and how long you should take it. For more information regarding how to take this medicine and what to do if you miss a dose, read the "Medication Guide".
Most people tolerate this medicine well. Common side effects include dry mouth, constipation, tremors, and increased hunger. It could also make you feel weak, tired, dizzy, or restless. You should wait until you know how it affects you before doing activities that require you to be alert, like driving. If these or other side effects become reasons you want to stop taking this medication, please talk to your healthcare team. You should not stop taking it suddenly unless your doctor says it's okay. 
As with any medicine, rare but more serious side effects can occur. With Olanzapine, this includes high blood sugar, high levels of fat in your blood, and weight gain. There is also an increased risk of death in elderly people with dementia-related psychosis. Some people have changes in mood, behaviors, and thoughts. You should know that if thoughts of suicide, or worsening mood or behavior ever occur, you should get help right away. You should read the "Medication Guide" for more information and to know which symptoms to watch for and when to report changes. To help keep this medicine safe for you, your doctor will follow your condition closely and may order blood tests.

Olanzapine can interact with other medicines. You should always check with your doctor or pharmacist before taking any other medicines, herbal remedies, and vitamins. Also, do not drink alcohol. 

Women should talk to their doctors before becoming pregnant and breastfeeding while taking this medication.

For best results with Olanzapine, tell your doctor if your condition does not improve or if it gets worse rather than better.
