Olanzapine is a prescription medication used to treat schizophrenia, a psychotic disorder. The medication treats the symptoms of this disorder, such as hallucinations, psychosis, and mania. This medication can come in various forms, including tablets, injections, or velotabs. As with most prescription medications, quitting this medication suddenly can result in olanzapine withdrawal symptoms.

Zyprexa® is a common brand name form of the olanzapine, which works on the brain's neurotransmitters. Neurotransmitters are chemicals stored in nerve cells, and they transmit messages between nerve cells. Dopamine and serotonin are neurotransmitters that regulate mood and behavior. When the brain has an over-activity of dopamine, it causes the schizophrenia.

Olanzapine is used to lessen the activity of dopamine, often to help control schizophrenia. This medication is also used to treat moderate to severe manic depression, also known as bipolar 1 disorder. Although, this medication is not addictive or commonly abused, it can still trigger severe olanzapine withdrawal symptoms.

Some common olanzapine withdrawal symptoms can include trouble sleeping, flu-like symptoms, and tremors. Other symptoms may include sweating, anxiety and muscle pain. Individuals may also experience a recurrence of the symptoms they were taking the medication for. These symptoms can occur when an individual decides to stop or change the dosage the doctor has prescribed.


Some of the more serious olanzapine withdrawal symptoms can include fatigue and severe headaches. Physicians' instructions should be followed on when and how to reduce this medication in order to reduce the risks of having these severe withdrawal symptoms. Stopping or changing the dosage can be very dangerous unless advised by a physician.

When prescribing this medication, a doctor will consider the other medications an individual is taking. He will make sure the combination of medication is safe. Reactions may occur when olanzapine is mixed with alcohol, sleeping tablets, and tricyclic antidepressants. Individuals should also avoid mixing this medication with barbiturates, benzodiazepines, and strong opioid painkillers. Some of the symptoms of these mixtures maybe be a lowering of blood pressure, dizziness, or even being faint.

The symptoms of olanzapine withdrawal can be severe, but these symptoms can be mitigated with the guidance and support of a physician. In addition to seeing a physician for guidance, it is not recommended that individuals decide to stop, decrease medication dosage, or increase the dosage because this may cause withdrawal. The individual’s doctor must monitor all changes in medication dosage to avoid these symptoms.

I have withdrawn from olanzapine to see if it relieves parkinsonism symptoms which it and other "atypical antipsychotics" cause. my latest neurologist thinks I do not have Parkinson's disease. I have been experiencing some of the symptoms referred to above but not the worst ones. you should watch out for Parkinson-type symptoms: trembling, balance problems.

I have been on 10mg for 2 months and really want to quit this due to the horror stories I read online. I wanted to go cold turkey but a taper seems to be the way forward. It's a very scary read all of this. I don't know how one survives the insomnia and nausea.

Insomnia is the worst side effect, in my opinion.

I was on 5mg for 20days stop cold and am sleepless and out of my mind now am worse than anxiety and depression. How long will this last?

Yes it is really that bad.

Yes, this a terrible medicine. I'm on only 2.5mg and the doctor told me to cut pill in half, so I could go off because of the side effects. I was only on it nine days and I woke up this morning very sick and with a a severe headache, nausea and shaking. This is a horrible drug. Beware if the doctor prescribes this. It is terrible.

I took Olanzapine for just six weeks and then reduced the dosage and finally off for about a week. I have anxiety now. Wondering how long will the withdrawal last?

Post 3

I reduced my olanzapine dose just by 2.5mg and I have vision changes and dizziness. I hope it goes away in a few days.

@turquoise-- I can't speak for everyone, but withdrawing from olanzapine was very difficult for me. Withdrawing from olanzapine seems to bring back and worsen all the symptoms this medication is supposed to treat. Of course, things get better with time, but I had serious issues for several months even though I reduced my dose very slowly. I had taken olanzapine for two years.

I had insomnia, mood swings, migraines, no appetite and nausea. I lost a lot of weight and just felt terrible overall.

My sister was just prescribed this medication. I looked up the potential side effects for her and read some terrible things about withdrawal from olanzapine. Among withdrawal symptoms, I've read everything from vomiting and nausea to hallucinations.

Is it really that bad?
