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

Omeprazole Krka contains the active substance omeprazole. It belongs to a group of medicines called “proton pump inhibitors”. These medicines work by reducing the amount of acid produced by the stomach.

Omeprazole 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 which connects the throat to the stomach), causing pain, inflammation and heartburn.
• Ulcers in the upper part of the intestine (duodenal ulcers) or in the stomach (gastric ulcers).
• Ulcers caused by a bacterium 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 which connects the throat to the stomach), causing pain, inflammation and heartburn. In children, the symptoms of the disease can include the return of stomach contents into the mouth (regurgitation), vomiting and insufficient weight gain.

Children over 4 years of age and adolescents

• Ulcers caused by a bacterium 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.

2. What you need to know before you take Omeprazole Krka

Do not take Omeprazole Krka

If you are not sure, talk to your doctor or pharmacist before taking omeprazole.
