I had posted about my success with neomycin for the treatment of intestinal gas. Well it has been about 31/2 months since neomycin and the gas is definately returning. I will call my doc next week but I imagine the decision is to take another 10 day dose or to try a different antibiotic. Flux, if my gas was caused by a bacterial imbalance in the colon and not SIBO, is there any way to correct that balance? Is it a motility problem that allows these gas forming bacteria to go crazy, or is it more likely an intolerance? I appreciate your help. Also what is your opinion about a low maintenance dose of an antibiotic? I have tried a lot of them including Cipro, tetracycline, tequin, flagyl, and amoxicillin. Neomycin was the only one that got rid of the gas for such an extended period of time. I remember that tetracycline did the same thing but the gas returned as soon as I finished. So flux, what now? I value your opinion in my decision as to what to try next for this gas problem. I read about oil of oregeno but the truth is that if it kills bacteria why is it any better than a prescription antibiotic? Also do you think motility drugs like lotronex or zelmac can reduce the amounts of intestinal gas by possibly working on the motility problem that may cause them to overgrow in the first place. Right now I am trying gastrocrom to see if food allergy is playing a role. Will report if it helps.Pete
