Ashwagandha With Cymbalta (Duloxetine) - Additional Details

It is important to note that while some animal studies have reported that ashwagandha can enhance serotonergic transmission through alterations of certain serotonin (5-HT) receptors, there is no evidence to suggest that ashwagandha increases the risk of serotonin-related effects and there have been no published case reports of serotonin syndrome when combined with other serotonergic drugs, like Cymbalta.

Some early studies have even suggested that ashwagandha may have some antidepressant effects, but more research is needed to understand the benefits and safety of taking it and Cymbalta together.

Overall, it is unlikely there is a clinically significant interaction between ashwagandha and Cymbalta.
