Zyprexa (olanzapine) withdrawal symptoms

Zyprexa withdrawal is the set of physical and mental symptoms that can appear when olanzapine is lowered or stopped, especially if it’s done quickly or without support. The most common are nausea, vomiting, insomnia, headache, dizziness, sweating, a racing heart, and anxiety. The most serious is rebound psychosis or mania.

Zyprexa withdrawal symptoms may include:

  • Rebound psychosis, mania, or hallucinations: caused by dopamine supersensitivity, and sometimes more intense than before treatment, notably after long-term use.13,29
  • Nausea, vomiting, and stomach pain: can persist for days or weeks.18,19
  • Insomnia: can last days, weeks, or longer.19
  • Anxiety and panic: along with restlessness and tension.18,29
  • Heavy sweating (diaphoresis).18,29
  • Rapid heartbeat at rest (tachycardia).18
  • Headache.19
  • Dizziness and vertigo.18
  • Diarrhea.18,29
  • Muscle and tissue soreness (myalgia) in ligaments and tendons.18,29
  • Dry mucous membranes.18
  • Catatonia.29
  • Oculogyric crisis: the eyes involuntarily roll upward.12,13,28

Who tends to have it harder: a large 2020 review of antipsychotic withdrawal studies in Frontiers in Psychiatry found withdrawal tended to be more severe in people over 50, and more severe in women than in men.18 Long-term treatment with these drugs raises its own concerns too.22

Withdrawal or relapse? Withdrawal symptoms and drug side effects can look like a returning or new mental illness. Caregivers need to be careful not to mistake them for one. The timing of when symptoms appear can help tell a psychotic relapse apart from a withdrawal reaction.16

What happens if you stop olanzapine suddenly?

Stopping Zyprexa abruptly can be a severe shock to the body, and the symptoms can be intolerable. That’s why the well-known warning applies: never abruptly stop taking antipsychotic medication.

Abrupt withdrawal of this class of drugs has documented medical effects, including nausea, vomiting, headache, and insomnia.19 Even after only a few weeks on Zyprexa, lowering the dose, even gradually, can bring acute symptoms that affect the whole body. The biggest concern is the brain’s dopamine system, explained below. Without proper support, coming off can trigger the same kind of crisis the drug was first prescribed for.

Without help and a good plan, Zyprexa withdrawal can be harsh. Some people stay on the drug simply to avoid getting too sick to work and cope with daily life. A slow, carefully monitored taper with trained professionals is the safer path.

Why withdrawal happens: Zyprexa and dopamine

Zyprexa appears to block dopamine at the D2 receptor, which is likely what calms manic or agitated symptoms. To adapt, the brain builds more dopamine receptors. Studies have shown increased D2 receptor binding after long-term antipsychotic treatment.7

  • While you take it: Zyprexa holds back dopamine’s effect.
  • When the dose drops: dopamine comes back to a brain with extra receptors. Even small reductions can flood those receptors and set off rapid-onset mania.
  • Beyond dopamine: Zyprexa affects many other brain chemicals, so similar disruptions can happen elsewhere in the nervous system, causing unusual and unpredictable reactions.

This is why tapering off Zyprexa or any dopamine blocker has to be conservative and very slow, giving the nervous system time to return to normal function.

How long does olanzapine withdrawal last?

There’s no single timeline. It depends on how long you took Zyprexa, how fast it was reduced, and how much support you had.

  • Physical symptoms: nausea, vomiting, and stomach pain can persist for days or weeks; insomnia can last days, weeks, or longer.18,19
  • Without support: after long-term use, symptoms can last weeks, months, or even years, especially when the drug was withdrawn too fast.
  • The brain’s recovery: receptors that adapted to the drug have no set return-to-normal time. It depends on genetics, how long you took Zyprexa, and diet (including caffeine and other stimulants), and can take months to years.7

How long does Zyprexa stay in your system? Its metabolites can show up in urine for about 4–10 days. That has little to do with how long it takes to fully adjust to being off it.

Coming off Zyprexa safely

A safe Zyprexa taper is slow, supervised, and built around the person, not a fixed schedule. We recommend inpatient antipsychotic withdrawal care. At Alternative to Meds Center, it happens in a comfortable residential setting in Sedona, Arizona.

What coming off Zyprexa looks like at ATMC:

  • Stabilize first. When you’re stable, eating well, and sleeping well, the slow and gentle taper begins.
  • Built around you. Your taper is individualized, never one-size-fits-all.
  • Adjusted as you go. Our clinical team is on site, watches how you respond, and adjusts the pace.
  • Precise doses. Our medical team plans each dose step, using half tablets or liquid preparations as needed, so each step is the right size.
  • Supporting your brain chemistry. Nutrient therapy, targeted supplements, and neurotransmitter support help rebalance neurochemistry.
  • Treating root causes. Testing early on looks for neurotoxins such as heavy metals, pesticides, and pollutants, which are gently removed. Diet, sleep, and other contributors are addressed too.

Tapering at home vs. at ATMC

At home At ATMC
Taper plan Often a fixed schedule Individualized and adjusted as you respond
Dosing You work out each dose change yourself Precise doses at every step
Rebound mania or psychosis Family left to manage a crisis Clinical team on site adjusts the plan
Withdrawal vs. relapse Easy to mistake for returning illness Recognized by staff who know antipsychotic withdrawal
Brain chemistry Not addressed Nutrient therapy and neurotransmitter support
Underlying causes Not addressed Toxins, diet, sleep, and counseling addressed

Helping a loved one come off Zyprexa

Families are often hit hardest. A person in withdrawal may be mentally fatigued or confused and may resist direction, which can make things very hard to manage. It’s difficult to watch someone you love suffer. These steps can help:

  • Know the symptoms. Withdrawal can look like relapse. Timing helps tell them apart, so note when changes start.16
  • Don’t let them stop suddenly. Abrupt withdrawal risks severe symptoms, including rebound mania or psychosis.13,29
  • Agree on a plan in advance. A voluntary safety agreement, sometimes called a “Ulysses contract,” can keep a taper on track if your loved one later resists following medical guidance.25
  • Choose care that recognizes withdrawal. If inpatient care isn’t possible, work closely with a doctor who has hospital admitting privileges and knows drug tapering.
  • Be ready to slow down. If things become unstable, the taper can resume later at a slower pace, with your loved one’s cooperation.

Why the right care matters

People have reported going to the hospital with severe antipsychotic withdrawal only to find the symptoms weren’t recognized. Some are told they’re imagining things and sent home. Medical training often doesn’t cover how to recognize withdrawal or help someone safely come off a potent drug like Zyprexa, and this appears to be a worldwide problem.6,15 In one study of 448 psychiatric inpatients in Japan, 338 medication errors occurred. More than half of all adverse drug reactions came from antipsychotics like Zyprexa, and the authors called for better patient monitoring.14,15

Zyprexa side effects

Zyprexa’s side effects have been controversial since 2006, when leaked Eli Lilly documents reported by the New York Times described illegal off-label marketing and the company downplaying side effects to protect sales.2,5,6,7,8,9,10,11 Side effects are a common reason people choose to come off the drug when the negatives outweigh the benefits.

Known side effects include:5,7,13,17,22,23,26-29

  • Everyday effects: weight gain, tiredness, drowsiness, headache, dizziness, dry mouth, stomach pain, weakness, restlessness, and aches, especially in the arms and legs.
  • Metabolic: high blood sugar, which can lead to diabetes.
  • Hormonal: raised prolactin, which can stop menstrual periods or cause lactation in women, and breast growth and impotence in men.
  • Movement and nerves: involuntary facial movements (tongue rolling, grimacing, lip-smacking), akathisia (intense inner restlessness that can lead to suicidality), seizures, tremors, slurred speech, and pins and needles or numbness.
  • Mood and mind: suicidal thoughts, mood swings, personality changes, and memory loss.
  • Sleep: sleepwalking and other parasomnias, and night terrors.
  • Mouth and throat: swollen gums, mouth sores, drooling, and difficult or painful swallowing.
  • Severe reactions: a life-threatening reaction with high fever, rigid muscles, heavy sweating, and confusion; DRESS (a rare, potentially fatal multi-organ reaction); yellowing of the skin or eyes (possible liver damage); sudden flu-like symptoms; and loss of bladder control.

Long-term antipsychotic use is linked to many problems, including the drugs ceasing to work over time.22

What is Zyprexa (olanzapine) used for?

Zyprexa (olanzapine) is a second-generation atypical antipsychotic. Antipsychotics quickly dampen emotions, hallucinations, and mania, so they can help bring a crisis under control. Exactly how Zyprexa works in the brain still isn’t fully understood.

  • FDA-approved uses: schizophrenia, mixed episodes of bipolar disorder, and psychosis, with age restrictions.
  • Black Box warning: the FDA has issued Black Box warnings on Zyprexa, including the extended-release injectable and any product containing olanzapine. Elderly patients with dementia-related psychosis should not be prescribed olanzapine because of an increased risk of death.5 It should not be prescribed under age 13 due to an increased risk of suicidality.
  • Lawsuits: Eli Lilly agreed to pay about $1.4 billion over off-label promotion of Zyprexa, one of the largest corporate fines in history.2 Similar settlements followed for Abbott ($1.5 billion), Johnson & Johnson ($2.2 billion), Pfizer ($2.3 billion), and GlaxoSmithKline ($3 billion).8-11


Off-label uses: Zyprexa and related products such as Zyprexa Zydis are sometimes prescribed for depression, OCD, PTSD, personality disorder, and Tourette’s syndrome in children or teens, as well as agitation and anxiety. Reviews warn there’s no strong evidence these uses work.1,24


Other names: olanzapine is sold under many brand names worldwide, including Zyprexa Zydis, Olanzapina Arrowblue, Olanzapine Torrent, Jolyon, Dopin, Marathon, and Kozylex. It isn’t a known street drug, so it has no slang names.

Why families choose Alternative to Meds Center

Alternative to Meds Center has specialized in antipsychotic withdrawal for nearly 20 years, and our results are documented in published evidence. Many of our staff have been through similar challenges, which is why they chose this work.

ATMC client outcomes after antipsychotic withdrawal

We often find that other contributors to psychotic episodes were never addressed: poor diet, genetic differences, recreational drug use, poor sleep, and more. Many of these can be resolved holistically. Alongside the taper, clients receive:


A family’s story: this young man was labeled schizoaffective and nearly lost in the psychiatric system. His mom wouldn’t give up. At ATMC we identified food allergies, did a physiological reboot, and helped him come off antipsychotics.

Our program lasts about 60 days on average. Slow, guided tapering can help a person move to drug-free living, or to the lowest dose that still gives a satisfying quality of life.

Zyprexa withdrawal FAQs

Can I stop Zyprexa cold turkey?
It isn’t safe. Stopping Zyprexa abruptly can be a severe, intolerable shock to the body. Because the brain adapts by adding dopamine receptors, a sudden stop can trigger rebound psychosis or mania.13,29 If you want to come off Zyprexa, talk with your prescriber or call us about a slow, individualized, supervised taper.
Is olanzapine withdrawal dangerous?
It can be. Beyond nausea, insomnia, and anxiety, withdrawal can include rebound psychosis, catatonia, a rapid heartbeat, and oculogyric crisis (eyes rolling upward).12,13,18,29 Risk is higher when the drug is stopped quickly or without support, which is why we recommend an inpatient, supervised taper.
How long does olanzapine withdrawal last?
It varies. Physical symptoms can last days to weeks.18,19 After long-term use, and especially when the drug is withdrawn too fast or without support, symptoms can last weeks, months, or even years.
How long does Zyprexa stay in your system?
Metabolites can show up in urine for about 4–10 days. Adjusting to life off the drug takes longer, because receptors that adapted to Zyprexa may need months to years to return to normal.7
Is it withdrawal or is my illness coming back?
Withdrawal and drug side effects can look like a returning or new mental illness. The timing of symptoms can help distinguish a withdrawal reaction from a psychotic relapse.16 Staff who know antipsychotic withdrawal are best placed to tell the difference.
What does Zyprexa do to the brain?
Zyprexa appears to block dopamine at D2 receptors and affects many other neurotransmitters. It belongs to a drug class called thienobenzodiazepines.4 Over time the brain may build more dopamine receptors in response.7 More research is needed to fully understand how it works.
What other medications or substances interact with olanzapine?
Alcohol and other psychoactive or medicinal drugs can interact with olanzapine and may cause enough drowsiness that you shouldn’t drive or operate machinery. Smoking cigarettes can lower olanzapine levels in the blood.3 Always tell your prescriber about any other drugs you use.
Can I come off Zyprexa after years of use?
Long-term use makes a slow, well-supported taper even more important. Slow, guided tapering can help a person move to drug-free living, or to the lowest dose that still gives a satisfying quality of life. Learn about Zyprexa alternatives.
