Official answer

  • There are no specific foods that interact with omeprazole, therefore there are no foods that you need to avoid.

Omeprazole is a medicine that is used to decrease the amount of acid your stomach makes.
It is used to treat conditions including duodenal ulcers, heartburn, indigestion, acid reflux, gastric ulcers, to reduce the risk of upper gastrointestinal tract bleeding and other health problems related to excess acid.

Food Tips when taking Omeprazole:

When you are suffering from excess acid, indigestion, heartburn or ulcer symptoms some foods or drinks may aggravate your symptoms. Foods and drink triggers for stomach and acid problems vary from person to person so watch how your body reacts to specific food and adjust your diet accordingly.

  • Acidic foods and drinks such as apples, lemons, grapefruit, oranges, tomatoes, wine, lemonade, coca-cola, fruit juices and energy drinks can make GERD, heartburn indigestion symptoms worse.
  • Greasy or fatty foods like french fries, pizza, deep fried chicken slow the digestive system down and often causes indigestion, heartburn and nausea.
  • Onions, garlic, chocolate, coffee, peppermint and some spices can also cause an increase in gastric symptoms.
  • White wine and beer have been shown in a study to cause gastro-oesophageal reflux in GERD patients with the study recommending patients to avoid drinking more that 300ml of beer or white wine.
  • Low alcoholic beer and wine was also studied to see if it caused reflux and it did, this was unrelated to the alcohol or acidity levels.
