Proton Pump Inhibitors (or PPIs) are a group of medicines used to reduce stomach acid and include omeprazole, lansoprazole, esomeprazole and pantoprazole. These medicines are very commonly prescribed but many patients continue taking them for longer than they may need. Usually a course of two to three months is sufficient to help heartburn or indigestion to settle.

As with any prescription medication, PPIs can cause side effects which are more likely if you take a high dose or use them for a long period of time. More and more evidence is coming out that suggests this group of medications may be linked to more problems than we knew about previously. We are therefore re-assessing which of our patients these medicines remain the best choice for.
