Omeprazole 20mg information
Omeprazole is a generic drug used to treat certain conditions where there is too much acid in the stomach. It is used to treat gastric and duodenal ulcers, erosive esophagitis, and gastroesophageal reflux disease (GERD). GERD is a condition where the acid in the stomach washes back up into the esophagus.
Omeprazole is a proton pump inhibitor (PPI). It works by decreasing the amount of acid produced by the stomach.
Losec is the branded version of Omeprazole. Omeprazole is medically equivalent to Losec but is available at a lower price.
One tablet daily. Try to take omeprazole at the same time each day to avoid missing any doses. The usual dose is once a day in the morning.
Antacids taken as required. Antacids are alkali liquids or tablets that can neutralise the stomach acid. A dose may give quick relief. There are many brands, which you can buy. You can also get some on prescription. If you have mild or infrequent bouts of dyspepsia you may find that antacids used as required are all that you need.
Always read the patient information leaflet before commencing treatment.

Impressively quick service. Easy site to navigate and meds delivered by reliable Royal Mail, so well pleased. Thank you!
“My full 5 star approval”
Great service, easy to navigate the questionnaire and far quicker service than waiting for the NHS services to approve and dispense your meds. Completely legitimate products, unlike so many other bogus sites. I have placed a couple of orders, even today, a Saturday, with estimated delivery this Monday. Awesome! This company has my full 5 star approval.
