Quick Answer: Zyprexa (olanzapine) withdrawal can cause insomnia, anxiety, nausea, sweating, restlessness, mood changes, and other symptoms, particularly when the medication is stopped suddenly. The safest approach to avoiding the worst of olanzapine withdrawal symptoms is generally to reduce or taper the drug gradually with guidance from the prescribing healthcare professional while monitoring for withdrawal and a return of psychiatric symptoms.

Can You Have Withdrawal From Olanzapine?
Yes, Zyprexa withdrawal symptoms can occur when the drug is discontinued, especially if it is stopped abruptly. Olanzapine is an atypical antipsychotic that changes the activity of certain chemical systems in the brain, and the body can adapt to its effects during treatment.
Physical dependence is not the same as addiction. A person can experience withdrawal after discontinuing an antipsychotic without having an addiction to the medication.
What Happens if You Stop Zyprexa Cold Turkey?
Stopping Zyprexa suddenly can increase the likelihood of withdrawal symptoms and may also increase the risk of psychiatric symptoms returning. Research into antipsychotic discontinuation has found withdrawal symptoms from Zyprexa are substantially more common following abrupt discontinuation than when medication is continued.
According to MedlinePlus, people taking olanzapine should not stop the medication without speaking to their doctor. If you want to discontinue Zyprexa because of side effects or another concern, discuss those concerns with your prescribing professional before changing your dose.
What Are the Symptoms of Zyprexa Withdrawal?
Zyprexa withdrawal may cause physical, emotional, sleep-related, and movement-related symptoms. Symptoms of olanzapine withdrawal can include:
- Insomnia or changes in sleep
- Anxiety and restlessness
- Irritability or agitation
- Nausea, vomiting, or diarrhea
- Abdominal discomfort
- Sweating
- Headaches
- Dizziness
- Muscle aches
- Tremors
- Increased heart rate
- Abnormal or involuntary movements
Symptom type and severity of withdrawal symptoms from olanzapine can differ significantly from person to person. Discuss withdrawal from Zyprexa symptoms that develop during a medication change with the healthcare professional overseeing treatment.
How Long Does Olanzapine Withdrawal Last?
There is no single timeline because the experience depends on factors such as dose, length of treatment, individual response, and how quickly the medication is reduced. Available research on antipsychotic withdrawal suggests that symptoms may emerge within days after discontinuation and that many acute symptoms occur during the first several weeks.
First few days: Some people may notice sleep disruption, nausea, anxiety, sweating, or restlessness soon after a significant dose reduction or stopping.
First several weeks: Olanzapine withdrawal symptoms may become more noticeable or gradually improve during this period. Changes in mood, movement, or psychiatric symptoms require continued monitoring.
Longer term: Some symptoms, particularly movement-related effects, can last longer. People with schizophrenia also need continued monitoring for relapse after an antipsychotic is withdrawn; NICE recommends monitoring for signs and symptoms of relapse for at least two years after withdrawal.

Is It Withdrawal or a Return of Schizophrenia Symptoms?
Withdrawal and a return of schizophrenia symptoms can overlap, so changes during a taper should be evaluated by a mental health professional. Withdrawal may involve symptoms such as nausea, sweating, headaches, insomnia, and physical restlessness, while recurring psychosis may involve hallucinations, delusions, paranoia, disorganized thinking, or substantial behavioral changes.
Sleep disruption, anxiety, and agitation can occur in either situation, which makes self-diagnosis unreliable. The National Institute for Health and Care Excellence recommends gradual antipsychotic withdrawal with regular monitoring for signs of relapse.
How Should Zyprexa Be Tapered Safely?
Zyprexa should generally be tapered gradually using an individualized plan developed with the prescribing healthcare professional. No universal reduction schedule is safe or appropriate for everyone.
A clinician may consider the current dosage, length of treatment, reason for discontinuing the medication, previous responses to medication changes, other medications, and history of psychosis or relapse. If significant symptoms appear, the prescriber may decide to slow, pause, or otherwise modify the plan.
We encourage individuals and families to keep the prescribing professional informed about changes in sleep, behavior, mood, thinking, and daily functioning throughout the process.
When Should You Seek Immediate Help for Olanzapine Withdrawal Symptoms?
Immediate help is warranted when a medication change is accompanied by severe psychiatric symptoms or concerns about safety. Seek prompt medical attention for suicidal thoughts, hallucinations, or paranoia that create a safety risk, severe confusion, dangerous behavior, extreme agitation, or a significant inability to care for basic needs.
For someone with schizophrenia, a noticeable return of psychosis should be taken seriously rather than assumed to be temporary withdrawal.

FAQs About Zyprexa (Olanzapine) Withdrawal
Can olanzapine withdrawal symptoms happen after only reducing the dose?
Olanzapine withdrawal symptoms can potentially occur following a significant dose reduction, not only after completely stopping an antipsychotic. How a person responds depends on their medication history and individual sensitivity, which is another reason gradual, medically supervised dose changes are recommended.
How long does Zyprexa stay in your system?
Olanzapine has a relatively long half-life, so it can remain in the body for several days after the last dose. The exact time varies based on factors such as age, metabolism, dose, liver function, and how long you've been taking the medication.
Is missing one dose of Zyprexa the same as withdrawal?
Missing one dose does not necessarily mean someone will experience withdrawal, but medication levels can begin to fall. If you miss a dose, follow the instructions from your prescribing professional or pharmacist rather than doubling the next dose without guidance.
Does stopping olanzapine affect appetite or weight?
Appetite and weight may change after you reduce or stop olanzapine because the medication can affect appetite, metabolism, and body weight during treatment. Changes vary widely between individuals and should not be a reason to stop the medication without medical guidance.
Can you lose weight after stopping Zyprexa?
Some people may lose weight after discontinuing olanzapine, particularly if their appetite decreases or the medication's metabolic effects lessen. Weight changes are not guaranteed, and medication decisions should be based on overall mental and physical health rather than weight alone.
Does olanzapine withdrawal mean you were dependent on the medication?
Withdrawal symptoms can reflect physical adaptation to a medication, but that is different from addiction. The body can become accustomed to olanzapine's effects during treatment even when the medication has been taken exactly as prescribed.
Can supplements help with olanzapine withdrawal?
No supplement has been established as a standard treatment for olanzapine withdrawal. Supplements can also interact with medications or affect psychiatric symptoms, so they should be discussed with a physician or pharmacist before being added during a medication change.
