We offer you to read the reviews of people who used the drug Sulfasalazin:

  1. Ruslan. I had to deal with this drug a couple of years ago, after I was hospitalized with a diagnosis of UC (total loss, moderate). Personally, I didn’t like Sulfasalazine. He helped weakly, a lot of side effects, his head ached constantly. Found an excellent substitute in the form of the drug with the active substance (mesalazine).
  2. Sasha. The son fell ill with Crohn's disease about a year ago, while doctors also tried sulfasalazine. But, unfortunately, sulfasalazine did not help us at all. We were looking for a suitable drug for a long time, but I had to agree to an operation ...
  3. Milan She took the drug for a year after the doctors told me that I had erosive colitis. The diagnosis did not cause any doubts, since I had a colonoscopy. Initially, an expensive drug, salofalk, was prescribed for treatment. But, oddly enough, he practically did not help, neither the pain in his stomach subsided, nor the diarrhea did not stop. A week later, the doctor made a replacement of salofalk for sulfasalazine. From the second day began to improve. I did not feel any side effects. So not everything is expensive.
