Does anyone know the differences between Bentyl and Levbid, which IBS symptoms one is supposed to treat as opposed to the other?I have alternating D and C with my IBS. Several years ago, I took Levbid, which helped fora while and then seemed to stop working. I then switched to Bentyl, which had been helping me for about four years, but I've been having a flare up for the last two months andam looking into other possibilities, maybe going back to the Levbid, or perhaps finding a different type of drug. I've been taking Paxil for the past 10 days as a short term option, but some of the side effects are beginning to cause me some problems and I believe I will gooff of that soon.Appreciate any and all suggestions.
