Good Morning and welcome to HealingWell,Serotonin syndrome has been around for years and can be a very serious interaction or reaction.
In the 30 years I have been on depression medications no Dr. has ever talked to me about this and I take more than one of the meds that could cause it.
Here is a link that is very helpful:

Do ask your Dr. about your meds as not everyone gets Serotonin syndrome but it is very wise to know the drugs we are taking.
Thank you for the shared information.
Kindly,
Kitt
