Hello, everyone, I am considering using Serotonin Syndrome as the cause of death in one of my characters. He has been taking antidepressants for nearly all of his young adulthood and adulthood (he is now almost 50 years old) and, with an unexpected switching of his psychiatrist and seeing a fluctuation in his symptoms, I imagine the new doctor would add another SSRI or similar drug to the list, causing the spike in serotonin levels. I understand that the onset is pretty quick, usually within 24 hours or sooner of the addition of the new med. But can it kill as quickly, too? In the plot, his husband wakes up to find the character unconscious and/or deceased, after the character displayed some concerning (but unknown) symptoms the night before. Is that too soon of a period for my character to pass away? Or would this persist over days/weeks? What’s the best way to frame this plot device (or a similar one) so it makes the most sense? Thanks in advance!
