What medications cause neuroleptic malignant syndrome?
Causes. NMS is usually caused by antipsychotic drug use, and a wide range of drugs can result in NMS. Individuals using butyrophenones (such as haloperidol and droperidol) or phenothiazines (such as promethazine and chlorpromazine) are reported to be at greatest risk.
Can atypical antipsychotics cause neuroleptic malignant syndrome?
Neuroleptic malignant syndrome (NMS) is a rare but potentially fatal adverse event associated with the use of antipsychotics. Although atypical antipsychotics were initially considered to carry no risk of NMS, reports have accumulated over time implicating them in NMS causation.
Can risperidone cause neuroleptic malignant syndrome?
Neuroleptic malignant syndrome (NMS) is rare but one of the most serious adverse effects of antipsychotics. Here, we report a case of risperidone-associated NMS in which a successful rechallenge of risperidone was observed with a positive follow-up.
Can olanzapine cause neuroleptic malignant syndrome?
Neuroleptic malignant syndrome can occur with atypical antipsychotics like olanzapine especially in the presence of risk factors. We should pay attention to this rare but potentially fatal complication. NMS remains a dangerous condition and has also been described in non-psychiatric settings.
Is NMS reversible?
After recovery, most people can start taking antipsychotic medicine again. Your doctor might switch you to a different drug. NMS can come back after you’re treated.
How do you reverse neuroleptic malignant syndrome?
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.
Why do antipsychotics cause neuroleptic malignant syndrome?
The most widely accepted mechanism by which antipsychotics cause neuroleptic malignant syndrome is that of dopamine D2 receptor antagonism. In this model, central D2 receptor blockade in the hypothalamus, nigrostriatal pathways, and spinal cord leads to increased muscle rigidity and tremor via extrapyramidal pathways.
What does neuroleptic malignant syndrome look like?
Symptoms of neuroleptic malignant syndrome usually include very high fever (102 to 104 degrees F), irregular pulse, accelerated heartbeat (tachycardia), increased rate of respiration (tachypnea), muscle rigidity, altered mental status, autonomic nervous system dysfunction resulting in high or low blood pressure, …
How do you test for neuroleptic malignant syndrome?
However, the following laboratory studies may be indicated, to assess severity and complications or rule out other diagnostic possibilities:
- Complete blood count (CBC)
- Blood cultures.
- Liver function tests (LFTs)
- Blood urea nitrogen (BUN) and creatinine levels.
- Calcium and phosphate levels.
- Creatine kinase (CK) level.

What is the difference between NMS and serotonin syndrome?
NMS and serotonin syndrome are rare, but potentially life-threatening, medicine-induced disorders. Features of these syndromes may overlap making diagnosis difficult. However, NMS is characterised by ‘lead-pipe’ rigidity, whilst serotonin syndrome is characterised by hyperreflexia and clonus.
Can antidepressants cause neuroleptic malignant syndrome?
Antipsychotic and antidepressant are often used in combination for the treatment of neuropsychiatric disorders. The concomitant use of antipsychotic and/or antidepressant with drugs that may interact can lead to rare, life-threatening conditions such as serotonin syndrome and neuroleptic malignant syndrome.
Can Abilify cause neuroleptic malignant syndrome?
A potentially fatal symptom complex sometimes referred to as neuroleptic malignant syndrome (NMS) has been reported in association with administration of antipsychotic drugs, including aripiprazole. Rare cases of NMS occurred during aripiprazole treatment in the worldwide clinical database.
Can olanzapine cause serotonin syndrome?
Olanzapine and risperidone, atypical antipsychotics, have been paradoxically reported to both induce a serotonin syndrome and to treat this syndrome. A case report by Haslett and Kumar noted the development of serotonin syndrome after olanzapine was added to a drug regimen of lithium and citalopram.
What are the side effects of olanzapine?
Olanzapine may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- dizziness, feeling unsteady, or having trouble keeping your balance.
- unusual behavior.
- difficulty falling asleep or staying asleep.
- difficulty walking.
