NovoLog (insulin aspart) is a rapid-acting insulin that helps control blood sugar in people with diabetes. It works quickly to lower blood sugar levels after meals.
Olanzapine is a medicine used to treat certain mental disorders. It helps to balance chemicals in the brain to improve mood and behavior.
NovoLog is used to improve blood sugar control in adults and children with diabetes. Diabetes is a condition where your body doesn't make enough insulin or can't use insulin properly, leading to high blood sugar. This medicine helps to lower your blood sugar levels.
Olanzapine is used to treat schizophrenia in adults and teens (13-17). It also treats manic or mixed episodes of bipolar I disorder in adults and teens (13-17). In adults, it can be used with other medicines to treat bipolar depression.
NovoLog is a man-made form of insulin that works like the insulin your body naturally makes. It helps sugar (glucose) move from your blood into your cells, where it can be used for energy. This lowers the amount of sugar in your blood.
Olanzapine is an atypical antipsychotic. It works by affecting the levels of certain chemicals in your brain. These chemicals include dopamine and serotonin, which can help improve mood, thinking, and behavior.

Never share your NovoLog FlexPen, FlexTouch, PenFill cartridge, or PenFill cartridge device with anyone else, even if the needle is changed. Sharing insulin pens or cartridges can spread blood-borne diseases. Changes in your insulin regimen should be made carefully under medical supervision. Low blood sugar can be life-threatening. Monitor your blood sugar regularly. Fluid retention and heart failure can occur if you take NovoLog with thiazolidinediones (TZDs).
Olanzapine can increase the risk of death in older adults with dementia-related psychosis. Olanzapine is not approved to treat this condition. When using olanzapine with fluoxetine, read the Symbyax label for more warnings.
Tell your doctor if you are pregnant or plan to become pregnant. Good control of diabetes is important during pregnancy for both you and your baby. Discuss the best way to manage your blood sugar with your doctor.
If you take olanzapine during the third trimester of pregnancy, your baby may have withdrawal symptoms after birth. There is a pregnancy registry to monitor outcomes in women who take atypical antipsychotics during pregnancy. Talk to your doctor.

Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, insulin aspart has 22,706 submissions while olanzapine has 23,962.
