Zyprexa (A complete review)

Zyprexa

Zyprexa is an antipsychotic used to treat schizophrenia and bipolar disorder. 

What is Zyprexa?

Zyprexa is an antipsychotic medication that is used to treat psychiatric disorders including schizophrenia and symptoms of bipolar disorder (manic depression). The generic name for Zyprexa is olanzapine. Zyprexa should not be prescribed to children under 13 years old. 

Zyprexa is an atypical or second generation antipsychotic and works by restoring the balance of serotonin and dopamine in the brain. Experts believe that Zyprexa mimics the activity of dopamine and serotonin, which are two of the brain’s major neurotransmitters that are important in regulating mood, pleasure, thinking, and behavior. Neurotransmitters are chemical messengers in the brain that relay information from one neuron to the next to regulate all of our behaviors. 

Dopamine is one of the neurotransmitters heavily involved in the reward center of the brain, and serotonin is a master regulator of sleep, appetite, and mood. Deficits in the dopamine system have also been implicated in psychotic and movement disorders.

Who is prescribed Zyprexa?

People who are diagnosed with schizophrenia may also be treated with Zyprexa. Schizophrenia is a severe mental disorder characterized by abnormal perception of reality. Symptoms involve hallucinations, delusions, disordered thinking and behavior that hinders one’s ability to function in daily life. Many people confuse dissociative identity disorder with schizophrenia. Schizophrenia and dissociative identity disorder are both serious mental health disorders that involve different symptoms and different treatments. 

Bipolar disorder is a brain disorder that causes extreme shifts in mood, energy, and activity levels, and severely interferes with everyday life. 

Symptoms of bipolar disorder include both manic and depressive episodes. Signs of a manic episode are: 

·      Feeling very “up” or elated

·      Increased energy and activity levels

·      Feeling jumpy or wired 

·      Trouble sleeping (insomnia)

·      Talking very fast about a lot of different things

·      Agitation or irritability

·      Thoughts racing 

·      Think they can do a lot of things at once 

·      Taking risks such as spending a lot of money or having reckless sex 

The following are symptoms of a depressive episode: 

·      Feelings of sadness, emptiness, or hopelessness 

·      Very low energy and activity levels 

·      Trouble sleeping (either sleeping too much or too little) 

·      Loss of enjoyment in hobbies or activities

·      Feelings of worry 

·      Trouble concentrating and trouble remembering things 

·      Changes in appetite (either eating too much or too little)

·      Feeling sluggish 

·      Thoughts of death or suicide

If you or someone you know is having thoughts of suicide, seek help immediately. 

There are two main types of bipolar disorder: Bipolar I Disorder and Bipolar II Disorder. 

Bipolar I Disorder is defined by manic episodes that last at least 7 days, or severe manic symptoms that require immediate hospitalization. Depressive episodes occur as well and usually last at least 2 weeks. Bipolar I Disorder patients may also have mixed episodes with both manic and depressive symptoms simultaneously. 

Bipolar II Disorder is characterized by a pattern of depressive episodes and hypomanic episodes. Hypomanic episodes have some features of typical manic episodes but are not severe enough to be considered manic. 

Zyprexa can also be used in combination with other antidepressants or antipsychotics.

What is some important information I should know before taking Zyprexa?

If you are taking Zyprexa for schizophrenia or bipolar disorder, it may take several weeks before your symptoms start to improve. Keep taking the medication as directed. Consult your doctor if your symptoms do not improve, or if they worsen. 

You should not stop taking Zyprexa without direction from your doctor. Stopping Zyprexa suddenly may cause unpleasant withdrawal effects. 

People, especially elderly people, with dementia-related psychosis should not take Zyprexa or other antipsychotic medications. Zyprexa can increase the risk of death in these patients. 

Long-term treatment with Zyprexa and other atypical antipsychotics can lead to the development of tardive dyskinesia (TD). TD is a movement disorder that is characterized by repetitive, involuntary movements which usually include eye blinking, grimacing, or lip smacking. This syndrome may be reversible if treatment with the antipsychotic is ceased. 

If you are taking Zyprexa, it is imperative that your doctor monitors your weight and blood sugar consistently. Patients taking Zyprexa or other atypical antipsychotics have developed hyperglycemia (high blood sugar). In addition, people taking Zyprexa, especially teenagers, may develop high cholesterol or triglycerides. 

Zyprexa has both risks and benefits. Talk to your doctor about your concerns so that he or she can make sure that you are getting the treatment that is right for you.

It is common to become hot or dehydrated when you are taking Zyprexa. Drink a lot of fluids, particularly in hot weather and while exercising. 

Zyprexa may impair your thoughts or reactions. Do not drive or do anything that requires alertness until you know how Zyprexa affects you. Avoid alcohol while taking Zyprexa. In addition, do not get up too fast from a sitting or lying down position because you may feel dizzy. 

You should not take Zyprexa if you are allergic to olanzapine.

It is imperative to tell your doctor if you have ever had any of the following conditions: 

  • liver disease
  • heart disease, high or low blood pressure
  • low white blood cell (WBC) counts
  • high cholesterol or triglycerides 
  • heart failure, heart attack, or stroke
  • breast cancer
  • seizures or epilepsy
  • diabetes
  • an enlarged prostate or difficulty urinating
  • bowel problems
  • narrow-angle glaucoma

Tell your doctor if you are pregnant or plan to become pregnant while using this medication. If you take an antipsychotic medication during the last 3 months of pregnancy, your newborn is at risk for experiencing problems. These include withdrawal symptoms, breathing problems, feeding problems, fussiness, tremors, and limp or stiff muscles. Zyprexa can pass into breast milk and may harm a nursing baby. Do not breastfeed while taking Zyprexa. 

The Zyprexa tablet may contain phenylalanine. If you have phenylketonuria (PKU), a genetic condition that affects the breakdown of the amino acid phenylalanine, tell your doctor right away.
