How long to stop using Omeprazole needs to be decided according to the patient’s own condition. Omeprazole, also known as PPI, is a proton pump inhibitor, mainly used to treat gastric ulcers, duodenal ulcers, reflux esophagitis and Zuo-Ai syndrome and other diseases. Excessive secretion of gastric acid is common in gastrointestinal diseases, and when the patient has this condition, he/she mostly feels discomfort in the stomach, with burning sensation, acid reflux, nausea, epigastric pain and other symptoms, and at this time, he/she can choose omeprazole for treatment. Oral medication starts to work 1~2 hours after taking the drug. For patients with Helicobacter pylori infection, the course of treatment is usually 2 weeks, the course of treatment for gastric ulcers is usually 6-8 weeks, and for duodenal bulb ulcers, the course of treatment is usually 4-6 weeks before the drug can be discontinued; the duration of treatment for reflux esophagitis is also 4-8 weeks, and for patients with severe reflux esophagitis, it is possible that there are still symptoms after 8 weeks of treatment, so you can continue to take the medication under the guidance of a doctor.
