Question: can duloxetine cause vivid dreams?
Answer: Many antidepressants suppress REM sleep. Escitalopram (Lexapro), sertraline (Zoloft), duloxetine (Cymbalta), and paroxetine (Paxil) have all been shown to have this effect. When your REM sleep is suppressed, you might wake up more frequently, which then allows you to remember more dreams.
