From the Guidelines
If fluoxetine or any SSRI induces suicidal thoughts or behaviors, seek immediate medical attention by contacting your healthcare provider, going to an emergency room, or calling a crisis hotline (such as 988 Suicide & Crisis Lifeline in the US). Do not stop taking the medication abruptly without medical guidance. Your doctor may recommend gradually tapering off fluoxetine and potentially switching to a different antidepressant class such as bupropion, mirtazapine, or vortioxetine. Close monitoring is essential during this transition period, and temporary addition of a benzodiazepine or low-dose antipsychotic might be prescribed to manage acute symptoms. SSRI-induced suicidality is most common in the first few weeks of treatment or after dose changes, particularly in adolescents and young adults, as these medications can initially increase energy and activation before improving mood, potentially giving patients the energy to act on existing suicidal thoughts. Family members should be informed about monitoring for warning signs such as increased agitation, talking about death, or sudden mood changes, as noted in studies such as 1. The FDA has issued a boxed warning for antidepressants, recommending that patients of all ages who start antidepressant therapy be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior, as mentioned in 1. It is also important to consider the potential benefits of treatment, as the USPSTF found adequate evidence that treatment of adolescents with screen-detected MDD is associated with beneficial reductions in symptoms, as stated in 1. In addition, the American College of Physicians recommends that clinicians assess patient status, therapeutic response, and adverse effects of antidepressant therapy on a regular basis beginning within 1 to 2 weeks of initiation of therapy, as recommended in 1. Overall, the management of SSRI-induced suicidality requires careful monitoring and prompt intervention to minimize the risk of harm, as supported by the evidence from 1.
Key Considerations
- Seek immediate medical attention if suicidal thoughts or behaviors occur
- Do not stop taking the medication abruptly without medical guidance
- Close monitoring is essential during the transition period
- Temporary addition of a benzodiazepine or low-dose antipsychotic may be prescribed to manage acute symptoms
- Family members should be informed about monitoring for warning signs

From the FDA Drug Label
Patients, their families, and their caregivers should be encouraged to be alert to the emergence of anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania, mania, other unusual changes in behavior, worsening of depression, and suicidal ideation, especially early during antidepressant treatment and when the dose is adjusted up or down. Such symptoms should be reported to the patient’s prescriber or health professional, especially if they are severe, abrupt in onset, or were not part of the patient’s presenting symptoms. Symptoms such as these may be associated with an increased risk for suicidal thinking and behavior and indicate a need for very close monitoring and possibly changes in the medication
If fluoxetine induces suicidality, close monitoring is necessary, and changes in medication may be required. Patients should be advised to report any symptoms such as anxiety, agitation, or suicidal ideation to their prescriber or health professional, especially if they are severe or abrupt in onset 2.
- Key actions include:
- Monitoring for symptoms of suicidality
- Reporting symptoms to the prescriber or health professional
- Possible changes in medication
- Main considerations are:
- Close monitoring of the patient
- Potential changes in medication to mitigate the risk of suicidality
From the Research
Fluoxetine Induced Suicidality
- Fluoxetine, a Selective Serotonin Reuptake Inhibitor (SSRI), has been associated with suicidality in some cases, but studies have shown that it does not directly cause suicidal behavior at a substantially higher frequency than other antidepressants 3.
- A meta-analysis of 18 trials found that fluoxetine treatment did not result in greater worsening of suicidality, but was associated with greater improvement and faster resolution of ideation compared to placebo 4.
- However, some studies suggest that fluoxetine-induced akathisia, a condition characterized by subjective and objective restlessness, may be a mediator of de novo suicidal ideation 5, 6.
- Akathisia has been proposed as a possible explanation for the emergence of suicidal ideation during fluoxetine treatment, and gradual increments of fluoxetine dose and prompt recognition and treatment of akathisia may reduce the risk of suicidal ideation 6.
- Retrospective and controlled studies have found no relationship between fluoxetine and the emergence of suicidal ideation, but case reports of akathisia or suicidal ideation with other SSRIs suggest that similar mechanisms may be involved 7.
Management of Fluoxetine Induced Suicidality
- If fluoxetine is suspected to have induced suicidality, it is essential to monitor the patient closely and adjust the treatment plan as needed.
- Gradual increments of fluoxetine dose and prompt recognition and treatment of akathisia may reduce the risk of suicidal ideation 6.
- In cases where akathisia is suspected, the addition of propranolol or discontinuation of fluoxetine may help alleviate symptoms 6.
- Patients should be educated about the potential risks and benefits of fluoxetine treatment and encouraged to report any changes in their mental state or suicidal ideation.
