SSRI's can have psychedelic side effects
That being said, it's with very rare use and high dosing, and has a sliver of a safety margin. The first time I took zoloft (with lots of weed) I had some very vivid CEVs that I couldn't recreate in intensity until at least my 10th acid trip.
The reason the well known ones are well known is because they're the best. Opiates, benzos, amphetamines, etc
(Disclaimer for the desperate and the naive) I dont recommend you take a bunch of prozac and expect to trip, you could get serotonin syndrome or other serious mental side effects. If you are desperate to trip but cant source legit (illegal) psychedelics, look into LSA. Psilocybin mushrooms are also easier to grow, and more accessible than you may think.
