Neuroleptics, also known as antipsychotic medications, are used to treat and manage symptoms of many psychiatric disorders. They fall into two classes: first-generation or "typical" antipsychotics and second-generation or "atypical" antipsychotics. Both first and second-generation antipsychotics are used in various neuropsychiatric conditions.
Is a neuroleptic the same the as an antipsychotic?
Neuroleptic malignant syndrome (NMS) is a life-threatening idiosyncratic reaction to antipsychotic drugs characterized by fever, altered mental status, muscle rigidity, and autonomic dysfunction. It has been associated with virtually all neuroleptics, including newer atypical antipsychotics, as well as a variety of other medications that affect ...
What is the prognosis of neuroleptic malignant syndrome (NMS)?
You're also more likely to get it if you:
- Take a high dose of the drug
- Quickly increase your dose
- Get the medicine as a shot
- Switch from one antipsychotic drug to another
How to treat NMS?
Neuroleptic Malignant Syndrome (NMS) is a severe neurological disorder caused by the adverse effects of antipsychotic and neuroleptic drugs, such as clozapine, Abilify, Sordinol, Risperdal, Clorazil, Seroquel, and Haldol. The symptoms of Neuroleptic Malignant Syndrome include:
Does Abilify cause neuroleptic malignant syndrome?
How do you manage neuroleptic syndrome?
Nonpharmacologic management centers on aggressive supportive care including vigilant nursing, physical therapy, cooling, rehydration, anticoagulation. Pharmacologic interventions include immediate discontinuation of antipsychotics, judicious use of anticholinergics, and adjunctive benzodiazepines.
What MED do you give for neuroleptic malignant syndrome?
Medicines used to treat NMS include: Drugs that relax tight muscles, such as dantrolene (Dantrium) Parkinson's disease drugs that make your body produce more dopamine, such as amantadine (Symmetrel) or bromocriptine (Parlodel)
What is NMS and how is it treated?
Neuroleptic malignant syndrome (NMS) is a rare and life-threatening reaction to the use of any neuroleptic medication. Neuroleptics, also known as antipsychotic medications, treat and manage symptoms of many psychiatric conditions. NMS is characterized by the following: High fever (hyperthermia).
How do you manage a patient who develops neuroleptic malignant syndrome?
Treatment of patients with neuroleptic malignant syndrome may include the following:Benzodiazepines for restraint may be useful.Stop all neuroleptics.Correct volume depletion and hypotension with intravenous fluids.Reduce hyperthermia.
How long does it take for NMS to resolve?
The most important intervention is to discontinue all neuroleptic agents. In most cases, symptoms will resolve in 1-2 weeks. Episodes precipitated by long-acting depot injections of neuroleptics can last as long as a month. See Treatment and Medication for more detail.
Is NMS reversible?
The mortality rate of NMS is estimated to be as high as 20% and the usual cause of death is due to acute renal failure. Fortunately, with early recognition and intervention, it is usually reversible without any serious complications.
Do people recover from NMS?
With treatment, most individuals with NMS will recover within 2–14 days . Once a person has recovered, a doctor might prescribe them a different antipsychotic medication or a lower dosage. If a person does not receive treatment for NMS quickly enough, they can develop serious complications .

Neuroleptic malignant syndrome (NMS) is a rare, but potentially lethal neurological emergency. Fifty percent of traumatic brain injury (TBI) patients will have emotional disorders and post-traumatic agitations.
What is the priority action with a patient with NMS?
The first and most critical step in the treatment of NMS is discontinuation of the neuroleptic medication. If dopamine agonists such as amantadine are being used, they should be continued, as their sudden withdrawal may worsen symptomatology.
Is neuroleptic malignant syndrome reversible?
Previous reports have shown that most patients with neuroleptic malignant syndrome recover without neurologic sequelae. Some patients with neuroleptic malignant syndrome show reversible magnetic resonance imaging (changes in the brain.
How is NMS diagnosed?
The diagnosis is confirmed by the presence of recent treatment with neuroleptics (within the past 1-4 weeks), hyperthermia (temperature above 38°C), and muscular rigidity, along with at least five of the following features: Change in mental status. Tachycardia. Hypertension or hypotension.
Why is NMS a medical emergency?
INTRODUCTION Neuroleptic malignant syndrome (NMS) is a life-threatening neurologic emergency associated with the use of antipsychotic (neuroleptic) agents and characterized by a distinctive clinical syndrome of mental status change, rigidity, fever, and dysautonomia.
What is the priority action with a patient with NMS?
The first and most critical step in the treatment of NMS is discontinuation of the neuroleptic medication. If dopamine agonists such as amantadine are being used, they should be continued, as their sudden withdrawal may worsen symptomatology.
What is fluphenazine used to treat?
Fluphenazine is an antipsychotic medication used to treat schizophrenia and psychotic symptoms such as hallucinations, delusions, and hostility.
What is dantrolene used for?
Dantrolene is used to help relax certain muscles in your body. It relieves the spasms, cramping, and tightness of muscles caused by certain medical problems such as multiple sclerosis (MS), cerebral palsy, stroke, or injury to the spine.
How is malignant hyperthermia treated?
The main treatment for malignant hyperthermia is a drug called dantrolene (Dantrium®). Anesthesiologists administer this drug immediately if they suspect malignant hyperthermia. They also stop giving the triggering anesthetic, and the surgeon ends the surgery as soon as possible.
What is neuroleptic malignant syndrome?
Neuroleptic malignant syndrome (NMS) is a rare reaction to antipsychotic drugs that treat schizophrenia, bipolar disorder, and other mental health conditions. It affects the nervous system and causes symptoms like a high fever and muscle stiffness.
How long does it take for NMS to show up?
Symptoms. These often start within 2 weeks after you first take the medicine or have your dosage changed. Sometimes, they show up a few days after you start to take it.
How long does NMS last?
NMS symptoms usually last for 7 to 10 days. They may include: NMS can damage muscles and cause very high or low blood pressure. If you’re not treated, you can get serious problems, like: Your doctor will look for the two main symptoms of NMS: a high temperature and stiff muscles.
What drugs can cause Parkinson's disease?
Ziprazidone ( Geodon) These drugs block a brain chemical called dopamine. That can make your muscles stiff and can cause rigid movements in people with Parkinson's disease. Any antipsychotic drug can cause NMS. But stronger drugs, like fluphenazine and haloperidol, are more likely to trigger it.
How to treat NMS?
Often, people with NMS get treatment in a hospital intensive care unit. The goal is to bring down your fever and give you fluids and nutrition.
What are the symptoms of NMS?
If you’re not treated, you can get serious problems, like: Your doctor will look for the two main symptoms of NMS: a high temperature and stiff muscles. To be diagnosed with it, you also need to have a few other warning signs, like a fast heartbeat, low or high blood pressure, and sweating.
Which drugs are more likely to cause NMS?
But stronger drugs, like fluphenazine and haloperidol, are more likely to trigger it. NMS is more common in men than in women. You're also more likely to get it if you: Some drugs used to treat nausea and vomiting can also cause NMS, because they block dopamine.
What is neuroleptic malignant syndrome?
Neuroleptic malignant syndrome is a rare but potentially life-threatening reaction to the use of almost any of a group of antipsychotic drugs or major tranquilizers (neuroleptics). These drugs are commonly prescribed for the treatment of schizophrenia and other neurological, mental, or emotional disorders.
What are neuroleptic medications?
neuroleptic medications under a doctor's supervision, immediate measures to restore appropriate water and nutrient levels, and steps to lower the individual's body temperature. Medications prescribed as treatment may include skeletal muscle relaxants, such as dantrolene; stimulators of dopamine production and activity, such as bromocriptine; and/or continuous perfusion of central nervous system depressants, such as diazepam.
Can neuroleptic malignant syndrome affect men?
Neuroleptic malignant syndrome may affect any person taking neuroleptic drugs. Men appear to be at higher risk than women. Some clinicians believe that the stronger neuroleptic medications are more likely to precipitate an attack of NMS.
Can NMS recur?
Recurrence of an attack of NMS is not uncommon. The risk of recurrence is closely related to the time elapsed between the end of the original episode of neuroleptic malignant syndrome and the beginning of renewed administration of an antipsychotic drug. If the waiting period is two weeks or less, about 63% will have a recurrence.
Can neuroleptic malignant syndrome be treated with electroconvulsive therapy?
Such patients must be carefully monitored since recurrences of neuroleptic malignant syndrome are not infrequent. Electroconvulsive treatments have been prescribed for patients with neuroleptic malignant syndrome with varied results.
How does dantrolene sodium help with neuroleptic malignant syndrome?
Dantrolene sodium directly relaxes muscles by inhibiting calcium release from the sarcoplasmic reticulum. Most patients respond to 400 mg/day or less.
What is electroconvulsive therapy?
In patients with neuroleptic malignant syndrome, electroconvulsive therapy (ECT) can help with the alteration of temperature, level of consciousness, and diaphoresis. It may also be useful in treating the underlying psychiatric disease in patients who are unable to take neuroleptics. [ 44, 45] A retrospective case series of 15 patients with refractory NMS who were treated with ECT over a 17-year period reported a remission rate of 73.3%. Although early response occurred after a mean of 4.2 treatments, an average of 17.7 treatments were needed to keep catatonic signs from recurring. [ 46]
How to identify possible precipitants of neuroleptic malignant syndrome?
To identify possible precipitants of neuroleptic malignant syndrome, prehospital personnel should try to obtain an accurate medication list. If that is impossible, they should bring all the medication bottles found with the patient.
What is the treatment for neuroleptic malignant syndrome?
Treatment of neuroleptic malignant syndrome (NMS) is mainly supportive; it is directed toward controlling the rigidity and hyperthermia and preventing complications ( eg, respiratory failure, renal failure). Monitoring and management in an intensive care unit (ICU) is recommended.
How long does it take for neurologic deficits to resolve?
No new focal neurologic deficits should develop, although cases of neurologic sequelae have been reported rarely. In most cases, symptoms will resolve in 1-2 weeks.
What can be used to reduce hyperthermia?
Patients should receive circulatory and ventilatory support as needed. Antipyretics, evaporative cooling, ice packs, and cooled intravenous (IV) fluids can be used to reduce hyperthermia. Consider prophylactic intubation for patients with excessive salivation, swallowing dysfunction, coma, hypoxemia, acidosis, and severe rigidity with hyperthermia. Aggressive fluid resuscitation and alkalization of urine can help prevent acute renal failure and enhance excretion of muscle breakdown products. [ 32]

Paparrigopoulos T, Tzavellas E, Ferentinos P, Mourikis I, Liappas J. Catatonia as a risk factor for the development of neuroleptic malignant syndrome: report of a case following treatment with clozapine. World J Biol Psychiatry. 2009. 10 (1):70-3. [Medline].
What is neuroleptic malignant syndrome?
Neuroleptic malignant syndrome (NMS) is a severe disorder caused by an adverse reaction to medications with dopamine receptor-antagonist properties or the rapid withdrawal of dopaminergic medications.
What is the next step in the management of NMS?
The next key step in the management of NMS is the initiation of supportive medical therapy. Aggressive hydration is often required, especially if highly elevated CPK levels threaten to damage the kidneys, and treatment of hyperthermia with cooling blankets or ice packs to the axillae and groin may be needed.
Which neuroleptic drug is most commonly associated with NMS?
Potent typical neuroleptics such as haloperidol, fluphenazine, chlorpromazine, trifluoperazine, and prochlorperazine have been most frequently associated with NMS and thought to confer the greatest risk.
What is the clinical manifestation of lethal catatonia?
Lethal catatonia is a life-threatening psychiatric disorder that can present with clinical features of fever, rigidity, akinesia, and altered mental status.41Although it can be difficult to distinguish it from NMS, the motor features in lethal catatonia are typically preceded by a few weeks of behavioral changes including ambivalence, apathy, withdrawal, automatisms, extreme negativism, and psychotic agitation.42As lethal catatonia typically requires neuroleptic treatment as opposed to being caused by such treatment, rapid clinical differentiation between these two disorders is extremely important (Table 3).
How long does it take for a person to develop NMS?
The diagnosis of NMS is based on history and the presence of certain physical examination and laboratory findings.5,6Patients typically develop NMS within hours or days after exposure to a causative drug, with most exhibiting symptoms within 2 weeks and nearly all within 30 days.7Although NMS has classically been characterized by the presence of the triad of fever, muscle rigidity, and altered mental status, its presentation can be quite heterogeneous, as reflected in the current Diagnostic and Statistical Manual of Mental Disorders(Fourth Edition [DSM-IV] criteria (see Table 1).8The clinical course typically begins with muscle rigidity followed by a fever within several hours of onset and mental status changes that can range from mild drowsiness, agitation, or confusion to a severe delirium or coma.
What are the laboratory findings of NMS?
Characteristic laboratory findings seen in NMS include elevated creatinine phosphokinase (CPK) due to rhabdomyolysis and leukocytosis, but these are neither specific for the syndrome nor present in all cases.14When rhabdomyolysis is present, it can be severe enough to cause renal failure, requiring hemodialysis.13Additional common laboratory abnormalities include a metabolic acidosis and iron deficiency.15The cerebrospinal fluid (CSF) and imaging studies are usually normal, but an electroencephalogram (EEG) may show nongeneralized slowing.7
What is the best treatment for NMS?
In more severe cases of NMS, empiric pharmacologic therapy is typically tried. The two most frequently used medications are bromocriptine mesylate, a dopamine agonist, and dantrolene sodium, a muscle relaxant that works by inhibiting calcium release from the sarcoplasmic reticulum.
What is NMS in medical terms?
NMS is a rare condition that can occur as a result of exposure to antipsychotic drugs. Doctors use these drugs, which decrease dopamine activity, to treat various neurological disorders.
What is the NMS reaction?
NMS is a rare and potentially deadly reaction to the use of antipsychotic medications. These medications, also called neuroleptics, prevent the overactivity of dopamine. Dopamine is a neurotransmitter that carries messages between cells.
Why do people with NMS need mechanical ventilation?
People with NMS are at a greater risk of abnormal heart rates due to autonomic dysfunction and may need treatment in the form of mechanical ventilation. Doctors may also give people skeletal relaxers to prevent or stop dangerous muscle rigidity.
How many white blood cells are in a microliter of blood?
A normal white blood cell count is 4,000–11,000 per microliter of blood. A person with NMS commonly has up to 40,000 white blood cells per microliter. People with NMS also often show elevated levels of CPK, which indicates higher disease severity.
What is the effect of autonomic dysfunction on the body?
Autonomic dysfunction affects the functioning of the heart, lungs, gastrointestinal system, and bladder. People with NMS will also develop muscle rigidity, fever, and an altered mental status.
What is neuroleptic malignant syndrome?
Neuroleptic malignant syndrome (NMS) is a rare neurological condition associated with the use of antipsychotic medications. Autonomic dysfunction, or damage to the nerves that control involuntary bodily functions, is a key feature of the condition.
How many NMS cases are fatal?
While NMS can be life threatening, fewer than 10% of cases are fatal.
