  https://www.uptodate.com/contents/serotonin-syndrome-serotonin-toxicity/print

  Serotonin syndrome is a potentially life-threatening condition associated with increased serotonergic activity in the central nervous system. […] This review will discuss serotonin syndrome. […] A summary table to facilitate the emergency management of serotonin syndrome is provided. […] Five principles are central to the management of serotonin syndrome: Discontinuation of all serotonergic agents, supportive care aimed at normalization of vital signs, sedation with benzodiazepines, administration of serotonin antagonists, and assessment of the need to resume use of causative serotonergic agents after resolution of symptoms. […] For mild cases, discontinuation of inciting medications, supportive care, and sedation with benzodiazepines are generally sufficient. […] Moderately ill patients require more aggressive treatment of autonomic instability, close monitoring of vital signs and cardiac monitoring, and possibly treatment with a serotonin antagonist.

  Serotonin syndrome is a clinical diagnosis and therefore requires a thorough review of medications and physical examination. The two mainstays of serotonin syndrome management are to discontinue the serotonergic agent and to give supportive care. Most patients improve within 24 hours of stopping the precipitating drug and starting therapy. […] For mild serotonin syndrome, treatment involves discontinuing the offending agent and supportive therapy with intravenous fluids, correction of vital signs, and symptomatic treatment with a benzodiazepine. Patients should be admitted and observed for 12 to 24 hours to prevent exacerbation. […] For moderate serotonin syndrome, treatment also involves stopping the serotonergic agent and giving supportive care. Symptomatic treatment with a benzodiazepine and nonserotonergic antiemetics is recommended, and standard cooling measures should be implemented for hyperthermia. Patients should be admitted and observed for 12 to 24 hours to prevent exacerbation.

  For severe serotonin toxicity, treatment should focus on management of airway, breathing, and circulation ie, the ABCs. The two primary life-threatening concerns are hyperthermia (temperature 40C or 104F) and rigidity, which can lead to hypoventilation. […] Controlling hyperthermia and rigidity can prevent other grave complications. Patients with severe serotonin toxicity should be sedated, paralyzed, and intubated. […] Antipyretics have no role in the treatment of serotonin syndrome since the hyperthermia is not caused by a change in the hypothalamic temperature set point. […] Serotonin antagonists have had some success in case reports, but further studies are needed to confirm this. […] Cyproheptadine is a potent 5-HT2A antagonist; patients usually respond within 1 to 2 hours of administration.

  Key treatments: […] Hyperthermia needs to be controlled with physical cooling techniques (e.g., cooling blanket, Arctic Sun, fan). […] Agitation should be controlled as discussed above, to prevent muscular activity that could worsen hyperthermia. […] Extreme hyperthermia (e.g., temperature over ~41.1 C) poses an immediate life-threat, since this may lead to rhabdomyolysis, seizure, metabolic acidosis, and disseminated intravascular coagulation. […] Intubation may occasionally be required for the following reasons: […] In extreme cases, chest wall rigidity may interfere with ventilation. […] Profound hyperthermia. […] Uncontrollable agitation. […] Status epilepticus. […] Ongoing paralysis may be useful initially, to gain control of hyperthermia.

• #24 Serotonin Syndrome – StatPearls – NCBI Bookshelf

  https://www.ncbi.nlm.nih.gov/books/NBK482377/

  Discontinue all serotonergic agents is the first step in treating serotonin syndrome. As serotonin syndrome is a toxicity, the condition resolves with the removal of the offending agents. However, specific serotonergic agents, such as fluoxetine, have long half-lives, which may cause symptoms to persist for multiple days. […] After discontinuation of serotonergic agents, supportive care to normalize the vital signs is recommended during the serotonergic agent’s detox from the body. Supportive care includes administering intravenous fluids and oxygen (goal of saturation 94%), cardiac monitoring, and correction of vital signs in autonomic instability. […] Chemical restraint (sedation) is highly preferred in serotonin syndrome, as physical restraints may still result in significant muscle contractions and worsen the condition. Benzodiazepines are the preferred agents, as they have no anticholinergic or serotonergic properties, and they are not dopamine receptor antagonists.

  Serotonin Antagonists. The administration of an antidote (serotonin antagonists) is not required in all cases of serotonin syndrome. However, if supportive measures, vital signs management, and chemical sedation do not adequately treat serotonin syndrome, then antidotes can be considered the next step. Cyproheptadine has nonspecific 5-HT1A and 5-HT2A antagonistic properties and some anticholinergic properties, but its major mechanism functions as a histamine-1 receptor antagonist. The histamine-1 receptor antagonism also assists with sedation. Notably, cyproheptadine is only available as an oral pill but can be crushed and administered via nasogastric or orogastric tube. The initial dose recommended is 12 mg, with 2 mg administered every 2 hours until adequate clinical response. Notably, inconclusive evidence exists for the efficacy of cyproheptadine, with reports documenting different outcomes.

• #27 Drug-Induced Serotonin Syndrome

  https://www.uspharmacist.com/article/drug-induced-serotonin-syndrome

  In general, treatment of SS first involves discontinuing the offending drug(s) and providing the patient with supportive care. Many mild-to-moderate SS cases are self-limiting and usually resolve within 24 to 72 hours. […] Resolution of more severe cases will likely take much longer. In such cases, supportive care, drug discontinuation, and administration of medication (e.g., diazepam 5 mg IV to reduce hypertonicity and neurologic excitability) may be sufficient to resolve mild symptoms. […] Patients with severe symptoms may need sedation, paralyzation, and intubation. […] Administration of drugs with serotonin antagonist properties, such as cyproheptadine and chlorpromazine, has been utilized in a few patients. […] Cyproheptadine 4 mg orally is the most widely used antidote for SS. […] Although increased body temperature is common in patients with severe SS, antipyretic therapy usually is not recommended. This is because the fever that occurs with SS is caused by excessive muscular activity, not a change in the hypothalamic temperature set point.

  Discontinue Serotonergic Agents. The first step in managing serotonin syndrome is accurately and promptly recognizing the condition. Misdiagnosis is a common pitfall that has the potential to worsen outcomes, particularly if serotonin agents are continued. Thereby, patients with hyperthermia of unknown origin are not recommended to continue serotonergic agents. Discontinuation of all serotonergic agents is the first step in treating serotonin syndrome. As serotonin syndrome is a toxicity, the condition resolves with the removal of the offending agents. However, specific serotonergic agents, such as fluoxetine, have long half-lives, which may cause symptoms to persist for multiple days. […] Supportive Care. After discontinuation of serotonergic agents, supportive care to normalize the vital signs is recommended during the serotonergic agent’s detox from the body. Supportive care includes administering intravenous fluids and oxygen (goal of saturation ≥94%), cardiac monitoring, and correction of vital signs in autonomic instability. Intravenous crystalloids can be given to assist in treating volume depletion in hyperthermia.

  Treatment of serotonin syndrome is primarily supportive. The initial severity of presentation helps guide appropriate emergency department care. […] Care for mild cases includes a review of laboratory results, as indicated; the administration of IV fluids for dehydration/hypotension, provision of benzodiazepines (for agitation/restlessness), and avoidance of all serotonergic medications. […] Treat hyperthermia with cooling blankets, fans, ice packs, and IV fluids. Antipyretics are not indicated, as the mechanism for temperature alteration is centrally mediated. Administer activated charcoal if a potentially lethal amount or combination of proserotonergic agents has been ingested and if the presentation is within 12 hours. Treat neuromuscular abnormalities with benzodiazepines. […] Patients with hyperthermia, depressed mental status, and vital sign abnormalities should be treated aggressively. All patients should be treated as above, with the addition of airway protection and ventilation if needed. Paralysis and mechanical ventilation may be necessary to avoid worsening muscle rigidity and increasing hyperthermia in any patient with a temperature higher than 41C.
