I am new to the forum and wondered if anyone is taking Lotronex for uncontrollable diarrheal? I took Lotronex several years ago and it was like a miracle drug for me and the diarrheal but recently the diarrheal came back with a vengeance and I started Lotronex again and I have had some days that the Lotronex did not control the diarrheal. Just wondering if anyone else has experienced this with Lotronex. Also, I wondered if the formula has been changed for Lotronex. Because when I took it before there was NO diarrheal whatsoever...I am just so disappointed that it is not working well for me this time.
