Patient Medication Information: uses, side effects, how to take - Dom-Lansoprazole
What is Dom-LANSOPRAZOLE used for?
Dom-LANSOPRAZOLE is used to treat conditions where reducing stomach acid production is needed, such as:
- Duodenal ulcer A duodenal ulcer is a sore on the lining of the duodenum, which is the beginning of the small intestine.
- Gastric ulcer A gastric ulcer is a sore on the lining of the stomach.
- Reflux esophagitis A reflux esophagitis is an inflammation of the swallowing tube (esophagus) resulting from regurgitation of gastric contents into the esophagus. Because stomach contents are acidic, this may result in irritation of the esophagus.
- Healing of non-steroidal anti-inflammatory drugs (NSAID)-Associated Gastric Ulcer
- Reduction of risk of NSAID-Associated Gastric Ulcer
- Symptomatic gastroesophageal reflux disease (GERD) GERD is a disorder that results from stomach acid moving backward from the stomach into the esophagus.
- Pathological hypersecretory conditions Pathological hypersecretory conditions are conditions in which the stomach produces too much acid, which comes up into the esophagus and causes heartburn.
- Treatment of the bacterial infection caused by Helicobacter pylori (H. pylori) in combination with other medications (e.g., the antibiotics clarithromycin and amoxicillin) to treat stomach ulcers.
Dom-LANSOPRAZOLE is also indicated for the treatment of erosive and non-erosive GERD in children, aged 6 to 17 years.
