You won't find any that say swimbladder because usually swimbladder problems aren't caused by bacteria or viral infections, rather, they're genetic issues.
You can try any broad-spectrum antibacterial food - I'm fond of Jungle Labs Antibacterial. There are others that will do the trick, but Jungle Labs is available in most Petsmart and Petcos.
As I mentioned, you should probably find a vet right away. She will likely need surgery, since the peas didn't help and she's floating all the time now. I would do that ASAP, since she's definitely developing a sore on her fin due to exposure to the air. Until you can get into the vet, you might try floating a towel on the surface, to keep her belly wet.
