Rotexmedica a small German manufacturing pharmaceutical company were purchased by a French pharmaceutical company called Panpharma about 2years ago . This seems to be leading to changes now, making it more difficult to find Rotexmedica B12 . It can be found more easily by using the German pharmaceutical reference number ( PZN) Which is 03862297 . Panpharma are also selling it under a new number which is 16199653. This number applies to the 10 ampoule pack .
The 100 ampoule packs are unobtainable at the moment . I will report any new development that I discover on this subject .
