Ah, I think Acute Care is a Canadian thing... Its mostly a pro-biotic with some vitamins. I don't think its as high fiber as you need. It also isn't giving him any liquid.
You're probably better off picking up 'Critical Care' (made by Oxbow) which is actual high fiber food with probiotics and vitamins. And you mix it with water.
You will have to feed it to him in a syringe. You can also mix it with pumpkin if he likes the taste.
But the bottom line is really to find out what's causing it. He may have a urinary tract infection or a dental issue or even a blockage. The Vet may have to give him fluids through an infusion under the skin.
How many carrot tops is he eating?
The fact that he's not urinating is troublesome. I'd honestly take him in ASAP.
I'm not sure how much your Vet knows about rabbits, but he can get fluids and get his urine tested and maybe an x-ray.
