What is Zyprexa?
Zyprexa, known generically as olanzapine, is a prescription medication used for the treatment of certain emotional, nervous, and mental conditions such as bipolar mania and schizophrenia. It can help reduce feeling of nervousness, increase concentration, and reduce incidence of hallucinations. It works by altering brain chemicals including serotonin and dopamine. Though it cannot cure diseases associated with an imbalance in the brain chemicals, it may provide temporary relief of the symptoms. Long-term use on a regular basis may also prevent some symptoms from returning.
Zyprexa belongs to a group of medications called atypical antipsychotics. Other drugs that belong to this class include aripiprazole (Abilify), clozapine (Clozaril), risperidone (Risperdal) and ziprasidone (Geodon). The FDA approved olanzapine in 1996. Originally, olanzapine formulations were manufactured and distributed by Eli Lilly and Company, but in 2011 the drug became available in its generic form.
Zyprexa is available in several forms. Oral Zyprexa tablets are available in olanzapine doses of 2.5 mg, 5 mg, 7.5 mg, 10 mg, 15 mg and 20 mg. Zyprexa Zydis orally disintegrating tablets come in olanzapine doses of 5 mg, 10 mg, 15 mg and 20 mg. The Zyprexa IntraMuscular injection (Zyprexa Relprevv) comes in a dose of 10 mg olanzapine. It is also available in parenteral drug formulation such as immediate release or extended release solution for injection.
It may be used along with Prozac (known generically as fluoxetine) for bipolar depression and depression that has not responded to other treatment options. Though Zyprexa cannot cure schizophrenia or bipolar disorder, it is effective at reducing and managing the disruptive symptoms.
Zyprexa is indicated for adults and children older than 13 years. Although it helps manage behavioral symptoms, Zyprexa is not recommended for treatment of behavioral problems due to Alzheimer’s disease or dementia in older adults. It is sometimes used to prevent nausea and vomiting due to chemotherapy or cancer treatment. It may also be prescribed by your healthcare provider for other medical conditions not discussed.
