I took the barium swallow with follow through, it was so fast it took 50 minutes. I'm vegan sensitive and I'm 5'5 10. When the radiologist saw my size they did not make me drink the whole thing. After I left the hospital within a few hours I had hives...it was okay I took three coffee enemas to get the barium out of my body, I also took bendryl with aspirin that is what the dr told me to do I did that twice within 15 hours. The next day we were driving, and I felt like I could not breathe, my heart began to race I felt my blood pressure go up and I started to sweat . I swear I felt like I was having a heart attack ...my wonderful husband took me to the ER well the dr and did not think it was barium but after I did research it is absolutely considered a toxic overdoes of barium . The next day I had swollen lymph nodes Barium is radioactive and I think I got too high of a dose for someone like me.
Anyhow NEVER EVER AGAIN. I was so scared to get in the first place.
