I am surprised your doctor took you off all your meds - I would have thought they would have left you on something at least if it didn't worsen the ulcer.

Treatment of Ulcers
Along with reducing stress and modifying lifestyle, doctors treat gastric and duodenal ulcers with several types of medicines, including H2-blockers, proton-pump inhibitors, antibiotics, and mucosal protective agents
Antibiotics. With the discovery of the link between ulcers and H. pylori peptic ulcers can be treated by a short course of combined high dose antibiotic therapy rather than acid-suppression alone. Without antibacterial therapy, there is a 75 percent chance of the ulcer reoccurring. With antibacterial therapy, there is a 1 percent chance of the ulcer reoccurring. There are two types of combination therapies currenly being used: triple therapy and dual therapy.
Triple therapy involves:
* Metronidazole (Flagyl)*, an antibiotic taken four times a day
* Tetracycline (Achromycin or Sumycin)**, an antibiotic taken four times a day
* Pepto-Bismol taken four times a day
This regimen lasts two weeks. This treatment is 90 percent effective in destroying the H. pylori bacteria and in reducing the risk of reoccurrence. (*doctor may substitute amoxicillin (Amoxil or Trimox); **doctor may substitute clarithromycin (Biaxin))
Dual therapy involves:
* Amoxicillin two to four times a day or Biaxin three times a day
* Prilosec two times a day
This regimen lasts two weeks. This treatment is 80 percent effective in destroying the H. pylori bacteria and in reducing the risk of reoccurrence.
