Olanzapine (Zyprexa^®) is a drug that is licensed to treat schizophrenia and bipolar disorder. This medication works by blocking or lessening the effects of several chemicals in the brain. However, olanzapine is not a cure for bipolar disorder or schizophrenia; it only controls the symptoms of these conditions. Olanzapine comes in tablet form and is usually taken once a day. If you forget to take your olanzapine dose as scheduled, take your missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not double your dose of olanzapine.

As with any drug, there are possible side effects with olanzapine. Some of the more common side effects seen with this drug include dizziness, drowsiness, and constipation.
