Adverse reactions associated with SSRIs and PD-1/PD-L1 inhibitors: a disproportionality analysis of the FDA adverse event reporting system

Selective serotonin reuptake inhibitors (SSRIs) are the primary choice for antidepressant therapy in cancer patients with depression. Programmed death-1 and programmed cell death-ligand 1 (PD-1/PD-L1) play a critical role in immune checkpoint inhibitors. To date, there have been no studies reporting adverse events (AEs) associated with the real-world use of PD-1/PD-L1 inhibitors-SSRIs combination.
