Belimumab
systemic lupus erythematosus
"I was one of the first patients in the United States to take Benlysta in June 2011.  I had to slow the infusions down to three hours instead of one and half hours.  I experienced nausea and an mild sort of asphasia (a sort of muddled thinking) and a headache.  I was also tired after the infusions.  Each time I had an infusion (6 total) my temperature would rise about a degree and I felt discomfort in the abdominal/ bladder region.  The discomfort only occurred after the Benlysta infusions! Eventually it did turn out to be serious and this is why I'm writing this review.  Though rare, the medicine lowered my immunity."
