Medication
If the use of the aforementioned strategies fails to control the agitation and correct vital signs, then there is some evidence for the use of serotonin antagonists.
Therapy
They are the first-line medication to reduce agitation and stabilize vital signs for mild to moderate serotonin syndrome. In addition to calming the patient, benzodiazepines lower blood pressure, slow down the heart, relax muscles, and help reduce fever caused by increased muscle activity.

What is the primary treatment of serotonin syndrome?
Benzodiazepines, such as diazepam (Valium, Diastat) or lorazepam (Ativan), can help control agitation, seizures and muscle stiffness. Serotonin-production blocking agents. If other treatments aren't working, medications such as cyproheptadine can help by blocking serotonin production.
What medications help with serotonin syndrome?
Selective serotonin reuptake inhibitors (SSRIs): This class includes fluoxetine (Prozac®), citalopram (Celexa®), sertraline (Zoloft®), paroxetine (Paxil®) and escitalopram (Lexapro®). This drug class is the most common antidepressant class involved in serotonin syndrome due to its widespread use.
What do you do if a patient has serotonin syndrome?
If you suspect you might have serotonin syndrome after starting a new drug or increasing the dose of a drug you're already taking, call your health care provider right away or go to the emergency room. If you have severe or rapidly worsening symptoms, seek emergency treatment immediately.
Does diazepam treat serotonin syndrome?
Diazepam, a GABA-mimetic, has been studied the most and has been shown to blunt the hyperadrenergic symptoms of serotonin syndrome. Therefore, diazepam not only works to sedate the patient, but it can also correct mild hypertension and tachycardia and reduce fever.
What are MAO inhibitors used for?
Antidepressants such as MAOIs ease depression by affecting chemical messengers (neurotransmitters) used to communicate between brain cells. Like most antidepressants, MAOIs work by ultimately effecting changes in the brain chemistry that are operational in depression.
Do benzodiazepines lower serotonin?
Although central serotonin neurons are thus implicated in the therapeutic actions of benzodiazepine tranquilizers, it is quite possible that the drugs actually act indirectly to reduce serotonin activity.
How do you treat SSRI overdose?
DecontaminationSSRI intoxication has an excellent outcome and activated charcoal is rarely indicated.If large ingestion of citalopram or escitalopram discuss with toxicologist as activated charcoal may be recommended.
Can Haldol cause serotonin syndrome?
Neuroleptic malignant syndrome, the disorder most often misdiagnosed as serotonin syndrome, is an idiosyncratic reaction to a dopamine antagonist (eg, haloperidol, fluphenazine) that develops over days to weeks.

Does lorazepam help serotonin?
Benzodiazepines such as lorazepam (Ativan®) or alprazolam (Xanax®) can be used to treat the agitation and other manifestations of serotonin syndrome. Many patients will require hospitalization, and some may even need to be monitored in an intensive care unit (ICU).
What does dantrolene treat?
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.
Does clonazepam affect serotonin?
These data suggest that serotonin receptor changes seen after chronic clonazepam may occur as a compensatory response to decreases in the presynaptic release of serotonin.
What is acute agitation?
Acute agitation is a common presenting symptom in the emergency ward and is also dealt with on a routine basis in psychiatry. Usually a symptom of an underlying mental illness, it is considered urgent and immediate treatment is indicated. The practice of treating agitation on an acute care basis is also referred to as rapid tranquilization.
What is the best drug for rapid tranquilization?
Among typical antipsychotics, haloperidol is the drug of choice in the rapid tranquilization setting. Another option is zuclopenthixol acetate, another high potency typical agent. Compared to haloperidol, it has a longer duration of action (48-72 hours) and a longer and less predictable onset.
Is promethazine a sedative?
The combination of haloperidol and promethazine may be pharmacodynamically beneficial, as promethazine has a sedative effect which may synergize with haloperidol and also possesses anticholinergic properties which confer a certain degree of protection against extrapyramidal side effects [4].
What is the mechanism of action of benzodiazepines?
Their mechanism of action is related to their ability to enhance the affinity of gamma-aminobutyric acid (GABA) to its GABA- A receptors, which are ligand gated chloride channels.
What is acute dystonia?
The most common of these, in an acute care setting, is acute dystonia (sustained, often painful spasm of a group of muscles), which may present as an oculogyric crisis, opisthotonos or as spastic torticollis.
Is haloperidol a controlled drug?
Certain common practices such as administration of haloperidol as needed, drug polypharmacy and extremely high doses of haloperidol have never been evaluated in a controlled setting. The risks of such an approach almost certainly outweigh the benefits, even if life-threatening adverse reactions are rare.
Does olanzapine cause agitation?
Olanzapine has numerous advantageous properties, as its most significant short-term effect is excessive sedation which is actually desired in this context, and it not prone to cause akathisia or extrapyramidal symptoms which can worsen agitation. However, it is expensive and IM formulation are not always available.
What is the best medication for agitation?
There is no type of medication considered to be “best” in all cases of agitation but 3 general classes of medication have been studied and used most frequently for agitation, including first-generation antipsychotics, second-generation antipsychotics, and benzodiazepines.
What is the name of the medication that is used in the acute setting?
Several of these medications are commonly used in the acute setting. Olanzapine (Zyprexa), ziprasidone (Geodon), and aripiprazole (Abilify) come in both intramuscular and oral preparations.
Why do people take FGAs?
The exact mechanism of calming with FGAs is unknown but most likely due to their inhibition of dopamine transmission in the human brain, which reduces the underlying psychotic symptoms causing the agitation .
Why are antipsychotics preferred over benzodiazepines?
For psychosis-driven agitation in a patient with a known psychiatric disorder (eg, schizophrenia, schizoaffective disorder, bipolar disorder), antipsychotics are preferred over benzodiazepines because they address the underlying psychosis. 2.
What is the purpose of medication restraint?
Rather, clinicians should, to whatever extent possible, attempt a provisional diagnosis of the most likely cause of the agitation and target medication to the most likely disease. 2.
Why is it important to recognize agitation associated with delirium?
First, the presence of delirium signals an underlying medical perturbation affecting brain function or a rapid change in the established environment of the brain.
Is agitation common in emergency departments?
Agitation is common in the medical and psychiatric emergency department, and appropriate management of agitation is a core competency for emergency clinicians. In this article, the authors review the use of a variety of first-generation antipsychotic drugs, second-generation antipsychotic drugs, and benzodiazepines for treatment of acute agitation, ...
What is selective serotonin reuptake inhibitor?
Selective Serotonin Reuptake Inhibitors (SSRIs) It is believed that the brain contains several hundred different types of chemical messengers (neurotransmitters) that act as communication agents between different brain cells. Serotonin is a neurotransmitter that is important in regulating a variety of body functions and feelings.
What is the name of the drug that increases the risk of serotonin syndrome?
Frova (frova triptan) Imitrex (suma triptan) Maxalt and Maxalt -MLT (rizatriptan) Relpax (eletriptan) Zomig and Zomig ZMT (zolmitriptan) In addition to triptans, other classes of medications increase the risk of serotonin syndrome if used with SSRIs and SNRIs.
What is the function of SNRIs?
Serotonin-Norepinephrine Reuptake Inhibitors (SNRIs) SNRIs inhibit the reabsorption of serotonin and norepinephrine in the brain. Norepinephrine is a chemical messenger in the brain that influences sleep and alertness. It is believed to be correlated to the fight-or-flight stress response. SNRIs include:
What is the best medication for migraines?
Triptans. Triptans are a class of drugs commonly used to treat migraine or cluster headaches. They act on serotonin receptors in the brain, thereby affecting serotonin levels. Examples of triptans include:
How to avoid serotonin?
To avoid increasing your risk of developing serotonin syndrome, tell your doctor about all drugs and dietary supplements you are taking. If you develop symptoms of serotonin syndrome, seek immediate medical attention.
Can triptans cause serotonin?
Jonathan Nourok/Getty. According to the U.S. Food and Drug Administration, there is increased risk of serotonin syndrome as a result of combining selective serotonin reuptake inhibitors (SSRIs) and selective serotonin-norepinephrine reuptake inhibitors SSNRIs with migraine headache medications called triptans.
Do SSRIs increase serotonin levels?
SSRIs inhibit the reuptake of serotonin in the brain. Reuptake is a process where neurotransmitters in the brain are reabsorbed and deactivated or recycled for future use. This causes an increase of serotonin levels, resulting in improved mood, decreased anxiety and inhibition of panic.
What is agitation in dementia?
Agitation is a behavioral syndrome characterized by increased, often undirected, motor activity, restlessness, aggressiveness, and emotional distress. According to several observations, agitation prevalence ranges from 30 to 50% in Alzheimer's disease, 30% in dementia with Lewy bodies, 40% in frontotemporal dementia, and 40% in vascular dementia (VaD). With an overall prevalence of about 30%, agitation is the third most common neuropsychiatric symptoms (NPS) in dementia, after apathy and depression, and it is even more frequent (80%) in residents of nursing homes. The pathophysiological mechanism underlying agitation is represented by a frontal lobe dysfunction, mostly involving the anterior cingulate cortex (ACC) and the orbitofrontal cortex (OFC), respectively, meaningful in selecting the salient stimuli and subsequent decision-making and behavioral reactions. Furthermore, increased sensitivity to noradrenergic signaling has been observed, possibly due to a frontal lobe up-regulation of adrenergic receptors, as a reaction to the depletion of noradrenergic neurons within the locus coeruleus (LC). Indeed, LC neurons mainly project toward the OFC and ACC. These observations may explain the abnormal reactivity to weak stimuli and the global arousal found in many patients who have dementia. Furthermore, agitation can be precipitated by several factors, e.g., the sunset or low lighted environments as in the sundown syndrome, hospitalization, the admission to nursing residencies, or changes in pharmacological regimens. In recent days, the global pandemic has increased agitation incidence among dementia patients and generated higher distress levels in patients and caregivers. Hence, given the increasing presence of this condition and its related burden on society and the health system, the present point of view aims at providing an extensive guide to facilitate the identification, prevention, and management of acute and chronic agitation in dementia patients.
What is the most widely investigated cannabinoid receptor agonist?
Cannabinoid receptors are also a potential target for agitation treatment due to their neuroprotective effects when employed at not psychoactive doses ( 222 ). Δ-9-tetrahydrocannabinol (THC) ( 132 ), dronabinol , and nabilone are the most widely investigated cannabinoid receptor agonists in clinical trials ( 222 ).
How long does it take for citalopram to work?
The FDA recommends a maximum daily dose of citalopram of 20 mg/day in patients above the age of 60 ( 157 ). Since the effects of citalopram take 2 weeks to ensue, citalopram should not be considered for the acute treatment of agitation ( 156 ). Escitalopram also showed clinical benefits in agitation treatment ( 158 ).
What is the FDA warning for antipsychotics?
The Food and Drug Administration (FDA) warning on the use of antipsychotic drugs (both typical and atypical) has led to better awareness about the risk associated with the use of these classes of drugs in cognitively impaired and older people, including increased mortality ( 103 – 105 ).
What is the NPS in dementia?
The presence of NPS in cognitively normal patients or in patients with mild cognitive impairment (M CI) is associated with an increased risk of progression to overt dementia. The need to identify, in the early stages of the disease, the population at risk of cognitive decline has led to the formulation of the concept of mild behavioral impairment (MBI) ( 34 ). Building on the prior definitions of a pre-dementia risk state ( 35, 36) and frontotemporal-MCI ( 37 ), the ISTAART NPS-PIA formally described MBI as the emergence of sustained and impactful NPS occurring after the age of 50, which are not encompassed in the psychiatric nosology, persist for at least 6 months, and manifest before or at the onset of MCI ( 34 ). Among the NPS associated with MBI, agitation is as frequent as 30%. It is important to understand the prevalence of agitation and impulsivity in pre-dementia syndromes as there is a potential opportunity for early intervention and higher impact in this early stage of disease, even though clinical trials need to be conducted to test and prove that behavioral and pharmacologic treatments in the pre-dementia stage can effectively improve agitation.
Does escitalopram help with agitation?
Escitalopram also showed clinical benefits in agitation treatment ( 158 ). For instance, a 6-week RCT compared escitalopram to risperidone and showed that both drugs reduced agitation. Although risperidone revealed efficacy earlier, the drug produced a higher burden of side effects ( 110 ).
Is haloperidol a good antipsychotic?
Among typical antipsychotics, haloperidol in a dose of 1.2–3.5 mg/day suppresses aggressiveness effectively but shows lower efficacy on agitation. Because of its remarkable side effects (e.g., extrapyramidal signs, prolongation of the QTc interval, arrhythmias, and increased mortality), haloperidol is not recommended ( 142 ). Atypical antipsychotics show comparable effectiveness and higher patient tolerance. For instance, in a multicenter, double-blind, placebo-controlled trial, 421 outpatients suffering from AD with psychosis, aggressiveness, or agitation were randomly assigned to receive olanzapine (mean dose 5.5 mg/day), quetiapine (mean dose 56.5 mg/day), risperidone (mean dose 1.0 mg/day), or placebo. Clinical benefits were observed in 32% of patients assigned to olanzapine, 26% of patients assigned to quetiapine, 29% of patients assigned to risperidone, and 21% of patients assigned to placebo, without significant differences ( 154 ). The CATIE-AD study evaluated the effects on NPS of olanzapine, risperidone, and quetiapine, compared with placebo. Among NPS, antipsychotic resulted to be more effective for specific behavioral symptoms, such as agitation ( 155 ). Regarding second-generation antipsychotics, high doses are not recommended as the risk of mortality is dose-dependent. The most common causes of death are cardiovascular, cerebrovascular, respiratory, and infectious (especially respiratory) complications ( 142 ).
