From the Guidelines
In a patient with serotonin syndrome, I would strongly recommend immediately discontinuing both sertraline and tapentadol to prevent further exacerbation of the condition. Serotonin syndrome is a potentially life-threatening condition that requires prompt intervention, with a mortality rate of approximately 11% and significant morbidity associated with it 1. The treatment often involves discontinuing the precipitating agent, which in this case are sertraline and tapentadol, and providing supportive care, including treatment of agitation, amelioration of hyperthermia, and management of autonomic instability 1.
After stopping these medications, supportive care should be initiated, including:
- IV fluids to manage autonomic instability
- Temperature management to prevent hyperthermia
- Benzodiazepines for agitation or tremor
- In severe cases, serotonin antagonists like cyproheptadine may be needed, with an initial dose of 12mg orally, followed by 2mg every 2 hours until symptoms improve, then 8mg every 6 hours 1.
Both sertraline (an SSRI) and tapentadol (which has serotonin reuptake inhibition properties alongside its mu-opioid effects) can contribute to excessive serotonin levels, and their combination particularly increases the risk of serotonin syndrome. For pain management after discontinuation, consider non-serotonergic alternatives such as:
- Acetaminophen
- NSAIDs
- Pure mu-opioid agonists like morphine or hydromorphone.
The patient should not restart either medication until fully recovered from serotonin syndrome, and future pain management should avoid serotonergic medications or use them with extreme caution and monitoring. It is crucial to prioritize the patient's safety and prevent further complications from serotonin syndrome 1.
From the FDA Drug Label
The development of a potentially life-threatening serotonin syndrome has been reported with SNRIs and SSRIs, including sertraline, alone but particularly with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, and St John’s Wort) and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid and intravenous methylene blue). If concomitant use of sertraline with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, buspirone, tryptophan, and St. John’s Wort is clinically warranted, patients should be made aware of a potential increased risk for serotonin syndrome, particularly during treatment initiation and dose increases Treatment with sertraline and any concomitant serotonergic agents should be discontinued immediately if the above events occur and supportive symptomatic treatment should be initiated
In a patient with serotonin syndrome, it is recommended to discontinue both sertraline and tapentadol (an opioid that can increase serotonin levels) immediately, as both drugs can contribute to the development of serotonin syndrome.
- Sertraline is an SSRI that can increase serotonin levels.
- Tapentadol is an opioid that can also increase serotonin levels. Discontinuation of these medications is necessary to prevent further increase in serotonin levels and to allow for supportive symptomatic treatment of serotonin syndrome 2 2.
From the Research
Serotonin Syndrome Management
In a patient experiencing serotonin syndrome, it is crucial to identify and cease the offending agent(s) that are contributing to the excess serotonergic activity.
- The decision to cease Sertraline or tapentadol depends on their potential to contribute to serotonin syndrome.
- Sertraline, a selective serotonin reuptake inhibitor (SSRI), is known to increase serotonin levels in the central nervous system and has been implicated in the development of serotonin syndrome, especially when used in combination with other serotonergic agents 3, 4, 5, 6.
- Tapentadol, an opioid, can also contribute to serotonin syndrome, although it is less commonly associated with this condition compared to SSRIs like Sertraline 6.
- Given the higher risk of Sertraline contributing to serotonin syndrome, it would be reasonable to cease this medication first, while also considering the cessation of tapentadol if necessary, to manage the patient's condition effectively 4, 6.
- The management of serotonin syndrome typically involves discontinuing the use of the substance that caused the excess serotonin levels and providing supportive care, such as intravenous fluids and electrolytes, as well as the use of serotonin antagonists like cyproheptadine in severe cases 3, 4, 6.
