Side effect or Something else?

So I recently got my Rexulti upped to a 2 mg dose. I am on my second day of taking the dose.

While I was talking to my cousin, I all of the sudden started laughing uncontrollably. To the point of tears coming out of my eyes and stuff.

It freaked me out, and it took a few minutes to stop.

I've never had this happen before, but I searched on Rexulti side effects and didn't see anything about this.

I took Rexulti for a while and didn't have and problems with laughter but had trouble with needing to move all the time but it took langer than a couple of days. I stopped taking it after a couple of months.

Strange. I had that happen to me once after drinking black cohosh tea. I bought the herb in a natural foods store, made the tea, drank it, and experienced absolutely uncontrollable laughter. Sounds funny, but it is not funny, at all. I was lying on the floor, couldn't stop laughing. My ribs were aching, but I couldn't get control of my emotion. I've never been on Rexulti, but your reaction sounds much like mine with the black cohosh. If it happens again, I would definitely tell your pdoc.
