1. What Omeprazole Combix is and what it is used for

Omeprazole belongs to a group of medicines called “proton pump inhibitors”. These medicines work by reducing the amount of acid produced by the stomach.

Omeprazole Combix is used to treat the following conditions:

In adults:

  • “Gastro-oesophageal reflux disease” (GORD). In this condition, acid from the stomach escapes into the gullet (the tube that connects the throat to the stomach), causing pain, inflammation and heartburn.
  • Ulcers in the upper part of the intestine (duodenal ulcer) or stomach (gastric ulcer).
  • Ulcers caused by an infection with a bacteria called Helicobacter pylori. If you have this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.
  • Ulcers caused by medicines called non-steroidal anti-inflammatory drugs (NSAIDs). Omeprazole may also be used to prevent ulcers if you are taking NSAIDs.
  • Too much acid in the stomach caused by a tumour in the pancreas (Zollinger-Ellison syndrome).

In children:

Children over 1 year of age and ≥ 10 kg

  • “Gastro-oesophageal reflux disease” (GORD). In this condition, acid from the stomach escapes into the gullet (the tube that connects the throat to the stomach), causing pain, inflammation and heartburn.

In children, symptoms of the disease may include food coming back up into the mouth (regurgitation), vomiting and insufficient weight gain.

Children over 4 years of age and adolescents

Ulcers caused by an infection with a bacteria called Helicobacter pylori. If your child has this condition, your doctor may also prescribe antibiotics to treat the infection and allow the ulcer to heal.

Your doctor may decide to perform periodic blood tests to monitor magnesium levels.
