6.Contents of the package and additional information

Omeprazol Aristo contains the active ingredient omeprazole. It belongs to a group of medicines called “proton pump inhibitors”. These medicines act by reducing the amount of acid produced by the stomach.

Omeprazol Aristo is used to treat the following diseases:

In adults:

• “Gastroesophageal reflux disease” (GERD). In this disorder, stomach acid passes into the esophagus (the tube that connects the throat to the stomach), causing pain, inflammation, and heartburn.
• Ulcers in the upper part of the small intestine (duodenal ulcer) or in the stomach (gastric ulcer).
• Ulcers infected by a bacteria called “Helicobacter pylori”. If you have this disease, it is possible that your doctor will prescribe antibiotics to treat the infection and allow the ulcer to heal.
• Ulcers caused by certain medicines called NSAIDs (nonsteroidal anti-inflammatory drugs). Omeprazol Aristo can also be used to prevent the formation of ulcers if you are taking NSAIDs.
• Excess acid in thestomach caused by a tumor in the pancreas (Zollinger‑Ellison syndrome).

In children:

Children over 1 year of age and= 10 kg

• “Gastroesophageal reflux disease” (GERD). In this disorder, stomach acid passes into the esophagus (the tube that connects the throat to the stomach), causing pain, inflammation, and heartburn.
  In children, the symptoms of the disease may include the return of stomach contents to the mouth (regurgitation), vomiting, and inadequate weight gain.

Children over 4 years of age and adolescents

• Ulcers infected by a bacteria called “Helicobacter pylori”. If your child has this disease, it is possible that your doctor will prescribe antibiotics to treat the infection and allow the ulcer to heal.

Do not take Omeprazol Aristo

• If you are allergic to omeprazole or any of the other ingredients of this medication (listed in section 6).
• If you are allergic to medications that contain proton pump inhibitors (e.g. pantoprazole, lansoprazole, rabeprazole, esomeprazole).
• If you are taking a medication that contains nelfinavir (used for HIV infection).

Do not take Omeprazol Aristo if you fall into any of the above cases. If you are unsure, consult your doctor or pharmacist before taking Omeprazol Aristo.
