It seems to be the drug with the least side effects so far ( sigh) so far!!! and it is held up BY THEM..
If it was any other drug company, I would believe the least side effects comment from Biogen. A neuro who tested Tysabri years ago told me that Biogen's data wasn't exactly trusted by the medical field and we all know what they told us about the safety of that drug before the recall.
Biogen has one of the slickest and effective marketing and sales departments going. Just watch how they promote BG12!!
