What is this drug for? Nexium (esomeprazole) is a prescription proton pump inhibitor used for the treatment of conditions caused by excessive production of stomach acid. It can therefore be prescribed for treating gastroesophageal reflux disease, stomach ulcers and duodenal ulcers. It can also be combined with clarithromycin amoxicillin to treat patients with H. pylori infections and ulcers. It can be used for children and adults. The way it works is by blocking a specific enzyme in the body decreasing the amount of acid produced in the stomach that way aiding in healing of the stomach and esophagus. Since the treatment period can be different depending on the patient's individual needs, you may need to buy esomeprazole online, that way saving yourself more money and needing less time to do the shopping. It's always a good idea to order Nexium online if you do not have health insurance or it does not cover your condition for any reason. The option of getting Nexium without prescription is quite popular these days, because not only do you no need to make the extra steps, you are also getting a fair deal on the treatment required. It's still recommended to see a doctor before you order esomeprazole at the online pharmacy of your choice, but the fact you can buy it in any amount necessary any moment sure sounds nice.
