FAQs

How does Omez 40 mg Injection work?

Omez 40 mg Injection works by inhibiting the actions of the gastric proton pump responsible for gastric acid secretion. Omez 40 mg Injection inhibits stomach acid production and alleviates symptoms of Zollinger-Ellison Syndrome, gastric ulcer, duodenal ulcer and Gastroesophageal Reflux Disease (GERD).

Does Omez 40 mg Injection affect bone health?

Prolonged intake of Omez 40 mg Injection may weaken the bones and lower haemoglobin levels. Your doctor may prescribe Vitamin B-12 for enhancing haemoglobin and calcium/vitamin D/magnesium supplements for bone health.

Does Omez 40 mg Injection treat stomach cancer?

Omez 40 mg Injection is not prescribed for stomach cancer. Please discuss with the doctor if you have any concerns regarding this.

Are gas and acidity the same thing?

No. Gas and acidity are two different discomforts. Acidity is caused due to improper functioning of the sphincter (valve located at the junction of the stomach and food pipe). As a result, stomach acid backflows and enters the food pipe's upper part, causing heartburn. On the other hand, gas is the result of the digestion of food and drinks, eliminating gases like carbon dioxide, hydrogen, nitrogen, methane, etc., from the body.

Does Omez 40 mg Injection interfere with or affect laboratory test reports?

Yes. Omez 40 mg Injection can alter certain medical tests like neuroendocrine tumours (secretin stimulation test) and urine screening tests for tetrahydrocannabinol (THC). So before undergoing such a diagnostics test, contact your doctor.

Does Omez 40 mg Injection treat gastric bleeding?

No. Omez 40 mg Injection prevents excess production of stomach acid, causing acid reflux and heartburn. If you find blood in your stool or mucous, immediately contact the doctor.

Disease/Condition Glossary

Zollinger-Ellison syndrome: Zollinger-Ellison syndrome is a rare condition in which tumours form in the pancreas (organ present near the abdomen and produces enzymes for digestion) or duodenum (first section of the small intestine) and lead to an increase in the production of stomach acid. Symptoms include nausea, vomiting, abdominal pain, diarrhoea, and weight loss.

Gastroesophageal reflux disease (GERD): Gastroesophageal reflux disease (GERD) occurs when stomach acid frequently flows back into the food pipe (oesophagus). This backflow (acid reflux) irritates the food pipe and causes heartburn. Symptoms include heartburn, sour or bitter taste in the mouth, and difficulty swallowing.

Gastric/duodenal ulcer: It is a painful condition followed by the development of sores or ulcers in the duodenum or stomach lining.
