What are proton pump inhibitors (PPIs) and what do they do?

PPIs work to reduce acid production in the stomach.

Large amounts of acid in the stomach can cause indigestion, acid regurgitation (acid coming ‘back up’ the throat especially when lying down) or sometimes stomach ulcers. PPIs stop stomach acid collecting in the stomach and therefore stop causing problems such as indigestion and regurgitation.

Why am I prescribed a proton pump inhibitor?

PPIs are prescribed by your doctor if you have symptoms such as indigestion, acid regurgitation or dyspepsia or have a history of stomach ulcers. They are also used to protect you stomach against other medications you are taking (such as aspirin or steroids) even if you have no symptoms of indigestion or dyspepsia.

How do I take my proton pump inhibitor?

PPIs are normally taken once daily but occasionally your doctor may increase this to twice a day to help to control your symptoms. PPIs can be taken at any time of the day.

Although PPIs are often prescribed to take regularly, some people find that they only need to take them occasionally to control any symptoms of indigestion or dyspepsia. However, if you are taking your PPI to protect you stomach against other medications you are taking (such as aspirin or steroids) then it should be taken regularly even if you have no symptoms of indigestion or dyspepsia.

Do I need to have any tests or be monitored because I am taking a proton pump inhibitor?

Usually no extra tests are required when you are taking a PPI but your doctor will tell you if you need to have any further investigations.

Are there any side effects?

The main side effects seen with PPIs include:

• Diarrhoea
• Constipation
• Headache
• Dizziness

These side effects should be mild, but if you have any concerns about these or any other side effects please contact your doctor or specialist nurse for advice.

Are there any problems taking proton pump inhibitors with any other medications?

Most other medicines can be taken safely with PPIs. However, only take tablets prescribed for you by your doctor and check with your pharmacist before taking any new medicines.
