Can remeron bi add to cymbalta (duloxetine) to reduce anxiety insomnia and to have mor appetite?

Maybe . . .: Yes Remeron can be added to Cymbalta (duloxetine) but you need to discuss this w/your prescribing physician, preferably the one prescribing both. More concerning is that your Medications list doesn't show Cymbalta (duloxetine) but rather Zoloft, Risperdal & Ativan. While side effects of Zoloft are comparable to Cymbalta (duloxetine), Risperdal & Ativan carry other potential complications. Bottom line, check w/your psychiatrist.
