Age-Dependent Analysis of Suicidal Ideation, Suicide Attempts, and Suicides Associated with SSRI and SNRI Drugs Based...

Background: Antidepressants such as SSRIs and SNRIs are widely prescribed; however, significant concerns exist regarding psychiatric adverse drug reactions (ADRs), particularly suicidal ideation, suicide attempts, and completed suicides. This study analyzes pharmacovigilance (PhV) data from the EudraVigilance database to assess the frequency of psychiatric ADRs, including suicide-related events, associated with six commonly used antidepressants. Another aim of the study is to evaluate the utility of pharmacovigilance data in providing insights into real-world risks associated with medications, highlighting the importance of improving the ADR reporting system and ensuring the completeness and reliability of ADR reports. Methods: Data from December 2001 to September 2024 were analyzed for duloxetine, citalopram, escitalopram, fluoxetine, venlafaxine, and sertraline. Reports were categorized by age, gender, and source, focusing on psychiatric ADRs and suicide-related events, including completed suicides and suicide attempts. Results: Psychiatric ADRs accounted for a substantial portion of total reported ADRs for the studied antidepressants, ranging from 33.9% to 38.2%. Venlafaxine had the highest count of psychiatric ADRs (13,134 cases), with duloxetine showing the highest relative percentage (38.2%). Completed suicides were most frequent with venlafaxine (1635 cases), while the highest percentage relative to total ADRs was observed for fluoxetine and citalopram (6%). ADRs occurred more frequently in women, particularly for duloxetine (67%) and sertraline (61.3%), and suicide attempts were prevalent in patients aged 18-64, with notable incidence in the 0-17 age group. Conclusions: This study highlights the significant patterns, risks, and underreporting of psychiatric ADRs associated with commonly prescribed antidepressants. Using EudraVigilance data and a worst-case scenario approach, it reveals the extent of suicide-related ADRs, age and gender disparities, and the impact of incomplete reporting on risk assessment.
