Omeprazole is a type of medication known as a proton pump inhibitor (PPI). This group of medicines offer effective treatment for conditions such as acid reflux, heartburn and gastro-oesophageal reflux disease (GORD). 

When Omeprazole is taken, this reduces the amount of stomach acid produced by the body, limiting the ability for acid to reflux up out of the stomach. 

One Omeprazole tablet is taken daily in the morning, and can be taken with or without food. Sometimes, a GP may recommend taking two Omeprazole capsules daily - in this case, tablets are taken once in the morning and once in the evening. 

Patients are usually prescribed Omeprazole 10mg or Omeprazole 20mg as a starting dose, with the possibility of increasing the dose to 40mg if ineffective.
