I had as bad as they can rate akathisia with Abilify. Cogentin, or less popularly, Artane can help. Unfortunately they are both anticholinergics which means they dry you out leading to dry mouth and certainly constipation. I didn't have that, but at the dose I needed, 3mg, I had sensitive and blurry vision. I stopped the Abilify and it went away.

When I had akathisia with Latuda I did some serious research and the consensus seemed to be that propranolol is the most effective "cure". I ended up taking it at 80mg. I may be wrong but I think it's a fairly innocuous drug. I needed to take a beta blocker before for a benign heart PVC. That was only a heart-targeted beta blocker, but I wouldn't (and I'm not) worried about it. The person to ask about it is a cardiologist. He would know much more about it than your psychiatrist.

For me the Latuda is worth taking propranolol.
