At another point I did take both Ablify and Saphris at the same time. Although my prescribing pdoc was certain they had different effects (and I can't remember what they were), I was once advised by another pdoc that they were at least redundant.

I also took both Abilify and Geodon at the same time but that was short lived due to Geodon's side effects.

Personally, I think I was on two at a time simply because my pdoc added and added medications instead of weaning and trying another. In the year and a half I saw her, I was weaned off of nothing but had numerous medications added to my cocktail.
