The same thing happened to me this past Thursday. It took two phone calls to the vet to straighten it out.
The standard "pink stuff" that vets and caretakers have used for years is 240 mg/5 mL, or 48 mg/mL. This is the standard pediatric suspension, and is what is referenced in our Medical Guide here.
The "new" stuff is 400 mg/mL. It can of course be used but the dosing volume has to be decreased accordingly! The stuff I got was a pale goldish-beige, which is what tipped me off that there might be a problem.
IF YOUR VETERINARIAN PRESCRIBES BACTRIM FOR YOUR PIG, DOUBLE OR TRIPLE-CHECK THE DOSING AND CONCENTRATION BEFORE LEAVING THE VET'S OFFICE!
I suspect the vets are so accustomed to using this med that they prescribe as they have for years, while some drug manufacturer is pushing a new formula to clinic purchasing personnel. Make sure everyone is on the same page before you leave the vet if you are given Bactrim for your pig!
(Lynx -- I have taken the liberty of making this a sticky. If that's inappropriate, I apologize, and please adjust as you see fit.)
Did find this but the oral is still the same-old same-old pink stuff. Perhaps one of the other concentrations delivered parenteraly? I had to look it up as it just means not administered via the mouth and alimentary canal. "Taken into the body or administered in a manner other than through the digestive tract, as by intravenous or intramuscular injection."

I would like to find the higher concentration product sold online so I can add better information.
