Not to be argumentative, but what exactly are they sweeping under the rug? I just went to look at their website, and I couldn't miss the possibility of white blood count changes as a possible side effect if I wanted to. It was quite literally either listed on every page, or appeared as part of a pop-up with each page I opened. All medicines have side effects, and this is one that occurs with Tecfidera, and which doctors are going to be regularly testing for. I am on Rebif, and they routinely test my liver enzymes and blood counts due to potential side effects it can cause. The OPs doctor may be wise to be taking his patients off the med...who knows...but I can't see how the drug company can be seen to be hiding this, as it is all over their literature.
