I am trying to find the US regulations that specifically relate to injectable B12 being by prescription only. The trouble is that I can't find them. No form of cobalamin is listed on the DEA's schedule of controlled substances, so it's clearly not limited that way.
It's probably limited based on the fact that it is administered with a syringe, so that is the angle I'm currently trying to focus on. But what I'm looking for is the regulation that states that any injectable compound requires a prescription. So far I haven't found that either. Anyone want to help me look? I'm poking around at the FDA website (http://www.fda.gov/default.htm) to try to locate it. If I want to submit a citizen petition to get a law changed, I have to reference the law I want changed (which is awfully hard to do if I can't find the actual law).
