I was prescribed premarin and was using it with no side effects. It cost more than I could afford so my doctor switched me to generic premarin. It made me bloated and my face and hands became swollen. I found out the filler in generic premarin was the culprit-so I had to quit taking it. I am having the same problem with some generic medicines I am taking now-but I cannot remember the name of the filler in the generic premarin which caused the side effect. How can I find out the name of the filler and how can I find out the fillers used in the medicines I am now taking?
