The effects of Abilify on the levels of dopamine receptors in the brain are controversial. Some animal model studies suggest that it increases them but others suggest that it decreases them.

If you are concerned about the possible side-effects of Abilify then talking with your prescribing doctor about trying another medication is a plan which is worth considering.
