If you just have an excessive amount of acid being produced in your stomach which would cause the redness and irritation to your stomach, then
prevacid once or twice a day is normal. However, your doctor should have performed something called a urease breath test or some other test to determine if those red spots were being caused by a bacteria call H. pylori. If this is the case, then the appropriate treatment would be commonly 2 specific antibiotics and prevacid or
prilosec to eradicate the bacteria and heal the lesions. I would double check if he found H pylori or not. That is very important in determining proper treatment.
