Zyprexa – A Complete Overview Including Dosage and Side Effects

Symptoms associated with schizophrenia or severe mood disorders can be treated by anti-psychotic medications such as Zyprexa, or Olanzapine. The drug was first patented in 1971 with the intended goal of reducing hallucinations and agitation in schizophrenic patients. By the time 2008 rolled around, the drug was widely prescribed and was also seen as a treatment option for bipolar disorders.

For patients who are taking the drug now, or who have questions regarding the drug, the following guide provides a comprehensive breakdown of the drug. We begin with a brief overview of the drug, then we discuss the doses and forms in which the drug is available in. We also tell you some of the important things you need to know before you begin taking the drug. In our side effects section, we discuss both common as well as severe side effects, along with rare symptoms you should look out for.

What Is Zyprexa?

Zyprexa, the brand name for Olanzapine, is a prescription drug used for the treatment of schizophrenia and mental disorders, such as bipolar disorder and depression. The drug may be used in combination with other antipsychotic drugs to treat mood disorders as well.

For those suffering from schizophrenia, Zyprexa helps to decrease the amount of hallucinations and help patients live as close to a normal life as possible. It does this by restoring the chemical balances in the brain—specifically dopamine D2 receptor, so that patients feel less irritated and less negatively about themselves. The end goal is to allow patients to gain clarity in their thought process.

For some patients who had underwent chemotherapy, this drug can be used to reduce nausea and vomiting associated with the treatment.

The Food and Drug Administration approved Zyprexa for treating psychotic disorders in 1996. The FDA, however, has not approved the drug for treatment of dementia-related problems. In fact, adults who have dementia may experience heightened risk of suffering from stroke and pneumonia when using the drug.

Patents should take Zyprexa in accordance to their doctor’s prescription and instructions. Also, be sure to follow all directions on the drug label. It is very important that patients do not exceed the dosage prescribed by their doctors, nor take dosage that is below the prescribed amount.

Zyprexa and olanzapine are available in tablet and injectable forms. For tablets, the drug comes in 2.5 mg, 5 mg, 7.5 mg, 10 mg, 15 mg, and 20 mg. There is also a disintegrating tablet (dissolves in the mouth and does not require swallowing) that comes in 5 mg, 10 mg, 15 mg, and 20 mg. The injectable form is an immediate-release medication that is available in 10 mg vials.

Patients who are taking oral Zyprexa should take one dose (5 to 10 mg) once a day without or without meals. Patients should eventually work up the dosage to 10 mg a day for more than a few days. Again, patients should follow their doctor’s instructions closely.

The drug may be taken in combination with other drugs as ordered by your doctor. In this case, read the instructions on the prescription labels carefully before taking the medications. It’s important that you do not alter the dosages prescribed by your doctor for each additional drug you’re taking on top of this drug. If you have questions, allergies, and concerns, be sure to discuss them with your doctor immediately.

Taking this drug with other medications may increase the risk of serious side effects associated with all of the drugs. Do not decrease or stop doses completely without consulting your doctor. When taking Zyprexa, patients should drink plenty of water to prevent dehydration and symptoms associated with dehydration.

Here are some important things to keep in mind when taking orally disintegrating Zyprexa tablets (Zyprexa Zydis). Keep the tablets inside its package until you are ready to take it. Instead of pushing the tablet through the foil, peel the foil back gently to avoid puncturing and breaking the tablet. Do not touch the tablets with wet hands, as the tablets will immediately start dissolving upon contact with liquid. Take the tablet and place it in your mouth and allow it to dissolve on its own without swallowing with water like you would with traditional oral medication. Do not chew the tablets either. While the tablet is in the process of dissolving, you may swallow a few times with or without liquids. Always wait for the tablets to dissolve before swallowing.

Patients who have missed a dose should take the missed dose as soon as possible. If it so happens that the next scheduled dose is near, do not take the missed dose as it would amount to over-dosage. The best thing to do is to just skip the missed dose altogether and take the next scheduled dose at its prescribed time.

Patients who have taken a larger dose than prescribed should get medical support immediately or call the Poison Control Help line at (800) 222-1222.

Do not drive a vehicle or operate machinery after taking your dose of Zyprexa, as it will make you sleepy and drowsy. You should also avoid drinking alcohol when taking this drug, as it will exacerbate feelings of drowsiness and sleepiness associated with taking the drug.

Smoking cigarettes and using other tobacco products may reduce the effectiveness of the drug. Patients who smoke or use tobacco products should let their doctors know before taking Zyprexa.
