PPIs. The most common treatment for stomach ulcers is a proton pump inhibitor (ex. Omeprazole) they prevent your stomach from making too much acid, allowing your ulcer to heal. Some ulcers are caused by a bacteria and will need to be treated with antibiotics along with the ppi. Make an appointment with your doctor to determine the source of the ulcer and what treatment is best for you.
Medicine. Treatmentis usually with a proton pump inhibitor (eg nexium, (esomeprazole) prilosec, etc.) you may need an endoscopy as well.
Prilosec type. There are prescription strength ppi's but that is not necessarily the only treatment.
Endo or RX. Either endoscopically treated with medications or medications alone.
Medications. Usually can be treated with medications unless they are bleeding when an upper endoscope (egd) can help.
Antiantacids. Try over the counter Prevacid (lansoprazole) or similar. If no improvempt in 2-3 weeks see gastroenterologist.
See your doctor. Your doctor can test you for H. Pylori. This is a bacteria found to be responsible for peptic ulcer disease. If positive, medication can be prescribed by your doctor. After you are examined and a careful history obtained, your doctor may order additional tests. See your doctor to be properly diagnosed and treated. Best wishes!
Treating an ulcer. First, I do not know what is omez next, with proper treatment (ie prilosec, nexium, (esomeprazole) pepcid) the ulcer ought to be fully healed in 6-8 weeks.
