Long Term Heartburn Pills (PPIs): Benefits, Risks, and Stopping

You started a heartburn pill years ago. It worked, so you kept taking it. Now you read a headline about risks, or your doctor asks if you still need it. You may not remember why you started.

This is very common. Proton pump inhibitors (PPIs) are among the most used drugs in Canada and the US. This guide explains who benefits from long term use, what the risks are, and how guidelines suggest reducing or stopping.

What PPIs are and what they treat

PPIs block the pumps in the stomach lining that make acid. Common examples are omeprazole, esomeprazole, lansoprazole, pantoprazole, and rabeprazole.[5]

They are used to treat:[1]

• GERD (gastroesophageal reflux disease), which causes frequent heartburn and acid regurgitation.
• Esophagitis (inflammation or damage of the food pipe from acid).
• Stomach and duodenal ulcers.
• H. pylori infection, as part of combination treatment.
• Ulcer prevention in some people who take NSAIDs, aspirin, or blood thinners.

PPIs are very effective. For many people, a short course heals the problem. Others need ongoing treatment.

What your doctor looks at

Guidelines from both countries focus on one key question: is there still a clear reason to take it?

Who should usually stay on a PPI

The American Gastroenterological Association (AGA) 2022 practice update says some groups should generally not stop:[2]

• People with complicated reflux, such as a history of severe erosive esophagitis, an esophageal ulcer, or a peptic stricture (narrowing).
• People with Barrett's esophagus (a change in the lining of the food pipe that raises cancer risk).
• People with eosinophilic esophagitis or idiopathic pulmonary fibrosis treated with PPIs.
• People at high risk of upper gastrointestinal bleeding.

Who may be able to reduce or stop

The Canadian deprescribing guideline, published in Canadian Family Physician in 2017, recommends reducing the dose, stopping, or switching to as-needed use for adults who:[3]

• Have taken a PPI for at least 4 weeks for heartburn, mild to moderate GERD, or esophagitis.
• Now have no symptoms.

This advice does not apply to people with Barrett's esophagus, severe esophagitis (grade C or D), or a history of bleeding ulcers.[3] The AGA update adds that people taking a PPI twice a day should usually be considered for a step down to once a day, and that every PPI user should have the reason reviewed regularly.[2]

The risks, in context

You may have read that PPIs are linked to many problems. Most of these links come from observational studies. These studies compare people who take PPIs with people who do not. They can show an association, but they cannot prove that the PPI caused the problem. People who need PPIs are often older and sicker to begin with.

Links reported in observational studies include:

• C. diff infection and other gut infections.
• Low magnesium and low vitamin B12 with long use.
• Bone fractures.
• Pneumonia, kidney disease, and dementia.

The strongest test came from a randomized trial of about 17,600 people with heart or blood vessel disease. They took pantoprazole or a placebo for about three years. The trial found no clear difference in most of these outcomes. It could not rule out a small rise in gut infections.[4]

FDA labels in the US and product monographs in Canada include warnings about some of these effects, such as C. diff diarrhea, low magnesium, and fractures with long use at high doses.[5] The AGA says the decision to stop should be based on whether you still need the drug, not on fear of these risks alone.[2]

How stopping usually works

There is no single right method. Guidelines describe several options:[2][3]

• Lower the dose, for example from twice a day to once a day.
• Take the PPI only on days when you have symptoms (on-demand use).
• Stop completely, either at once or after a taper.
• Use an antacid or an H2 blocker (such as famotidine) for breakthrough symptoms. Ask your pharmacist which is right for you.

Rebound heartburn is common for a few weeks after stopping, because the stomach can make extra acid for a short time.[2] This does not always mean you need the drug. Lifestyle steps may also help: avoid large meals late at night, raise the head of the bed, and limit foods that trigger your symptoms.[1]

Questions to ask your clinician

• Why did I start this PPI, and is that reason still present?
• Do I have Barrett's esophagus, severe esophagitis, or a bleeding risk that means I should stay on it?
• Could I lower my dose or use it only when I need it?
• What should I do if heartburn comes back when I cut down?
• Should I have my magnesium or vitamin B12 checked?
• How often should we review this medicine?

When to get care quickly

Call 911 or go to the emergency department if you:

• Vomit blood or material that looks like coffee grounds.
• Have black, tarry stools.
• Have chest pain, especially with sweating or shortness of breath. Do not assume it is heartburn.

See your clinician soon if you have trouble swallowing, pain when swallowing, weight loss you cannot explain, or ongoing vomiting.

Bottom line

PPIs work well, and some people need them for life. Many others started for a short-term reason and may be able to reduce or stop. Most feared risks come from observational studies, and a large trial found few clear harms. Canadian and US guidance agrees on the key step: review the reason with your clinician on a regular basis.
