bullous pemphigoid
"I had 4 rituxan infusions last year. Discontinued all meds in Dec. 2016. Symptoms returned within 2 weeks. Blood work in Jan. 2017 showed my numbers were still as high as when I was first tested a year earlier. Started again with the azathioprine and have had 4  rituxan infusions this year. Will not know if infusions worked until I have more blood work. My infusions take approximately 5 hours to avoid most side effects."
