I was sent this same generic pill by my pharmacy when I refilled the other day. I would be interested in hearing from someone if they were doing ok on the generic cortef. I was put on generic thyroid back in the early 90's and they ended up pulling them off of the market because they didn't work as effectively as synthroid. This is the only time I had ever had a problem with a generic but you just don't know sometimes unless someone else has the same problem.
