I've looked into at least 5 different retailers and it's all back ordered. Spoke with one representative for a company and she said that Pfizer has it on "indefinite back order." I'm guessing that this means there must have been some issue (possibly legal?) that's caused Pfizer to stop production of Synovex-H. Does anyone here know where it may still be found? Even if it costs a little extra. Any help or direction would be greatly appreciated.
