Risa: The regimine of Amoxicillin for at least two weeks, Flagyll for at least two weeks, and then Carafate as an ONGOING help is the proven way to cure ulcers, and it worked for us, but it will take at least 2 months for the ulcers to actually be healed. It's vital that you keep up with the Carafate (or sucralfate) during that time, and it must be given at least 20 minutes before meals, and preferably TWO HOURS apart from other meds. It coats the stomach and would prevent the proper absorption of the meds. It will also help if he has soup or softer food to eat as much as possible rather than kibble, as pieces of kibble could aggravate the ulcers, depending on their severity. I would also strongly recommend the use of Pepcid AC twice a day to reduce the acid reflux. I had excellent success using Pepcid AC tablets when fighting ulcers with Neo. It kept his stomach calm and his appetite normal. Here is what I did: Take one 10 mg Pepcid AC tablet and dissolve in 4.0 ml of water (I used distilled water). I then administered 0.25 ml of this solution twice daily. That is the equivalent of 1/8 of a tablet daily, or 1.25 mg of the active ingredient Famotidine daily. You have to shake the container briskly each time before drawing the 0.25 ml because there is some settling of the dissolved tablet. We gave him this in conjunction with Carafate, and continued this after 4 weeks of amoxicillin. His ulcers were cured in about 10 weeks, and they were very bad to begin with.
