What is serotonin syndrome toxicity?

What is serotonin syndrome toxicity?

Serotonin toxicity (commonly referred to as serotonin syndrome) is a potentially life-threatening drug-induced condition caused by too much serotonin in the synapses of the brain. 1–3. Patients present with a combination of neuromuscular, autonomic, and mental status symptoms.

Which drug toxicity causes serotonin syndrome?

The drugs and supplements that could potentially cause serotonin syndrome include: Selective serotonin reuptake inhibitors (SSRIs), antidepressants such as citalopram (Celexa), fluoxetine (Prozac), fluvoxamine (Luvox), escitalopram (Lexapro), paroxetine (Paxil, Pexeva, Brisdelle) and sertraline (Zoloft)

What causes excess serotonin?

Substances that may contribute to excess serotonin levels include: Some types of antidepressants. Triptan migraine medications. Illicit drugs such as cocaine, lysergic acid diethylamide (LSD), amphetamines, and ecstasy.

What is the difference between neuroleptic malignant syndrome and serotonin syndrome?

Key Messages. 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.

How does serotonin syndrome occur?

Serotonin syndrome happens when you have too much serotonin (a normal chemical) in your body. It’s usually caused by taking drugs or medications that affect serotonin levels. Stopping the drug(s) or medication(s) causing serotonin syndrome is the main treatment.

Is serotonin syndrome an emergency?

Serotonin syndrome (SS) is an often undiagnosed and potentially life-threatening adverse drug reaction caused by excessive activation of postsynaptic serotonin receptors. The actual incidence of SS is difficult to measure because so many cases go unrecognized [1].

How is serotonin syndrome diagnosed?

No single test can confirm a serotonin syndrome diagnosis. Your doctor will diagnose the condition by ruling out other possibilities. Your doctor will likely begin by asking about your symptoms, medical history and any medications you’re taking. Your doctor will also conduct a physical examination.

Is CK elevated in serotonin syndrome?

Leukocytosis and elevated hepatic transaminases are reported in at least 75% of NMS cases and increased CK in >90% of cases. These signs may be present in serotonin syndrome but are less common.

How does one differentiate between serotonin syndrome neuroleptic malignant syndrome and malignant hyperthermia?

Malignant hyperthermia is extremely rare in the postoperative setting, and serotonin syndrome has a faster onset and neuromuscular hyperactivity while neuroleptic malignant syndrome has a slower onset and neuromuscular hypoactivity.

How fast does serotonin syndrome happen?

Most cases of serotonin syndrome start within 24 hours after starting or increasing a serotonergic medication and the majority of those start within six hours.

How quickly does serotonin syndrome occur?

Serotonin syndrome symptoms develop quickly after taking the precipitating medicine—60% of cases occur within six hours. Most patients have symptoms within 24 hours. Symptoms can vary from mild to life-threatening and may include: Agitation.

Can blood test detect serotonin syndrome?

The serotonin test measures the level of serotonin in the blood. Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

How can you tell the difference between serotonin syndrome and neuroleptic malignant 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.

What are signs and symptoms of neuroleptic malignant syndrome?

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.

Is serotonin syndrome permanent?

Can Serotonin Syndrome Be Reversed? The symptoms of serotonin syndrome usually subside once you stop taking the medication causing the symptoms. Fortunately, there are generally no long-term or lasting complications of serotonin syndrome, though you should be conscious to avoid serotonin syndrome in the future.

What is similar to serotonin syndrome?

Neuroleptic malignant syndrome (NMS) bears some resemblance to serotonin syndrome, with similar symptoms of fever, mental status changes, and altered muscle tone.

What are extrapyramidal signs?

Extrapyramidal side effects are a group of symptoms that can occur in people taking antipsychotic medications. 1 Symptoms of extrapyramidal effects include an inability to sit still, involuntary muscle contraction, tremors, stiff muscles, and involuntary facial movements.
