Low risk, no synergy
There have been some case reports of serotonin syndrome in individuals who were given a combination of opioids and SSRIs. Other research has indicated a small increase in overdose risk for people who are prescribed CYP2D6-inhibiting SSRIs (e.g. fluoxetine and paroxetine) with oxycodone. Overall, risk is low with this combination but, as always, be mindful of your consumption.
Can you mix Fentanyl and SSRIs?
Neither substance is expected to meaningfully change the other. Both still carry their own individual risks.
This is a class-level answer, inherited from Opioids. Nothing specific to this exact pair is documented, so treat it as the default for the class rather than a measurement of these two drugs together.
- Fentanyl
- Synthetic — potent by micrograms, unevenly mixed

Checking more than two?
Combinations of three or more carry risks that no pair-by-pair chart can show. The checker rates every pair at once and flags the whole-mix ones on top.
