Oh wow, so I'm not alone in this. Funny that the pills didn't cause any of these problems to my knowledge...was it okay to ask if it was bladder, bowel, or both?

@Findingreason Abilify Side Effects: Common, Severe, Long Term - Drugs.com
Although incontinence is rare it does happen. Mine was bladder related. If you look on the overdose section of this link you will find that Abilify can affect the bowel. Maybe the change from pills to injections was enough for your bladder to react.

Your body could be highly sensitive to this med. Did your bowel incontinence happen around the time you started on the Abilify? It could be that you are one of the unlucky ones. Also have a look at the gastrointestinal side effects. Has to make you wonder.
