What is Omeprazole?
- Stomach acid helps with digestion and protects against harmful bacteria.
- A natural mucous barrier in the stomach prevents acid from causing damage.
- If this barrier weakens, acid can irritate the stomach lining, leading to inflammation or ulcers.
- Omeprazole reduces the production of stomach acid, relieving these symptoms.
- After consulting a prescriber, omeprazole can often be taken during pregnancy or breastfeeding.
- Omeprazole is also known by the brand name Losec.
- Always read the patient leaflet for a complete list of side effects and precautions.
How Does Omeprazole Work?
Omeprazole belongs to a group of medicines called Proton Pump Inhibitors (PPIs). It works by reducing the amount of acid produced in the stomach lining. This helps prevent ulcers from forming and allows any existing damage to heal, relieving symptoms such as indigestion and stomach pain.
Heartburn is a burning sensation in the chest caused by stomach acid rising into the oesophagus (food pipe), a condition known as acid reflux. Acid reflux can also leave an unpleasant taste in the mouth. By reducing stomach acid production, omeprazole helps prevent acid reflux and its associated symptoms.
How is Omeprazole Taken?
