What Medications Cause Heartburn? 10 Common Drugs

The most common culprits are aspirin, ibuprofen and other NSAIDs, antibiotics (especially tetracyclines), blood pressure medications (calcium channel blockers and beta blockers), bisphosphonates for osteoporosis, iron and potassium supplements, asthma drugs like albuterol and theophylline, benzodiazepine sedatives, and tricyclic antidepressants. These drugs trigger heartburn in one of two ways: by increasing stomach acid production or by relaxing the lower esophageal sphincter (LES), the muscle that normally keeps acid out of the esophagus. Heartburn, also called acid reflux, happens when stomach acid backs up into the esophagus, and frequent episodes can develop into gastroesophageal reflux disease (GERD). Below, we break down the 10 most common medications that cause heartburn, why they do it, and what you can do to manage symptoms without stopping treatment your provider has prescribed.

Understanding Heartburn

Heartburn is a type of indigestion that occurs when stomach acid backs up into the esophagus, the tube linking the stomach to the throat.

Many people use the term acid reflux interchangeably with heartburn. When heartburn happens frequently, it can develop into gastroesophageal reflux disease (GERD). In some cases, reflux symptoms may also be tied to underlying conditions like hiatal hernias or atypical presentations such as silent reflux (LPR), both of which can complicate medication-related heartburn.

1. Antibiotics

Certain antibiotics, particularly tetracyclines, a group of broad-spectrum antibiotics widely prescribed for common bacterial infections, are known triggers of heartburn.

Choosing an enteric-coated tablet may be gentler on your digestive tract. The special coating allows the pill to remain intact while passing through the stomach, reducing irritation.

2. Aspirin

Aspirin can stimulate increased acid production in the stomach, which often results in heartburn symptoms.

Beyond that, aspirin interferes with the body’s ability to produce protective prostaglandins, hormone-like substances, within the digestive tract. The prostaglandins located in the stomach are responsible for stopping cells in the stomach lining from generating and releasing too much acid.

3. Hypertension Medications

Two categories of blood pressure medications, calcium channel blockers and beta blockers, are commonly linked to heartburn. These drugs can loosen the lower esophageal sphincter (LES), permitting stomach acid to travel back up into the esophagus. Patients dealing with chronic LES weakness may benefit from advanced procedures like the LINX Reflux Management System, which is designed to reinforce the sphincter mechanism.

4. Osteoporosis Treatments

Osteoporosis medications called bisphosphonates frequently lead to heartburn. Some examples include:

• Alendronate (Fosamax)
• Ibandronate (Boniva)
• Risedronate (Actonel)

Certain medications taken at longer intervals tend to be gentler on the stomach. Zoledronic acid (Reclast), for example, is an infusion-based drug administered just once annually.

If you’re using a daily or weekly bisphosphonate tablet, make it a habit to swallow it with a full glass of water and stay upright for at least 30 minutes after taking it.

5. Ibuprofen and NSAIDs

Widely available over-the-counter (OTC) ibuprofen brands like Motrin and Advil can spark heartburn, and so can nonsteroidal anti-inflammatory drugs (NSAIDs) such as Aleve.

These drugs boost acid output in the stomach while simultaneously decreasing the production of protective prostaglandins.

6. Iron Supplementation

Consuming iron supplements may inflame the lining of your esophagus and contribute to acid reflux.

Iron has the potential to wear away the mucosa of the gastrointestinal (GI) tract. Notably, iron pill–induced gastritis, inflammation of the stomach lining, has only been observed in cases where iron is supplemented in pill form, not in liquid form.

7. Potassium Pills

Potassium supplements have the potential to irritate the esophageal lining. However, not everyone who uses potassium will experience heartburn.

To minimize the risk, take the supplement while seated upright, and follow it down with a full glass of water. Persistent irritation may sometimes be associated with motility issues like gastroparesis, which can amplify reflux symptoms.

8. Asthma and Respiratory Medications

Several asthma medications can intensify heartburn symptoms. Drugs such as theophylline (Theolair) or beta2-agonists like albuterol have a relaxing effect on the LES.

9. Sedatives and Sleep Aids

Drugs classified as benzodiazepines, including diazepam (Valium) and lorazepam (Ativan), are formulated to ease anxiety and promote relaxation. Unfortunately, they also relax the LES, potentially triggering heartburn.

Compounding the issue, most people tend to lie down shortly after taking these medications. Reclining can worsen acid reflux because gravity no longer assists in keeping stomach acid in place.

10. Older Antidepressants (Tricyclics)

Older tricyclic antidepressants (TCAs), including imipramine and amitriptyline, may worsen heartburn by reducing the rate at which the stomach empties. Delayed gastric emptying can sometimes overlap with conditions like achalasia, which also affects esophageal function.

TCAs are also known to relax the LES, raising the likelihood of heartburn episodes.

Newer psychiatric medications operate in a more focused manner and tend to produce fewer gastrointestinal side effects.

Managing Heartburn Caused by Medications

Always swallow medications with plenty of water.

Some limited research suggests that drinking water with a higher pH, such as alkaline water, which has lower acidity, might help ease reflux symptoms, though additional studies are needed to confirm this.

Pairing your medication with food may help lessen symptoms. Just be sure to verify with a healthcare provider beforehand to ensure that food won’t affect how the medication works.

Always take medications in an upright sitting position. Additionally, hold off on lying down for at least 30 minutes after swallowing them. For patients also struggling with weight-related reflux triggers, incisionless weight loss procedures may offer additional relief alongside medication management.

Effective Ways to Relieve Heartburn Symptoms

A number of lifestyle adjustments can minimize or prevent heartburn, such as:

• Steer clear of tight-fitting clothing.
• Opt for smaller, more frequent meals.
• Make regular exercise a habit.
• Shed excess weight if necessary.
• Stop or cut back on smoking and tobacco use.
• Manage and reduce stress whenever possible.
• Elevate your head at least six inches while sleeping.
• Allow at least three hours between eating and lying down.

There are also certain foods and beverages worth avoiding because they commonly trigger heartburn, including:

• Alcohol
• Carbonated beverages
• Citrus fruits and their juices
• Caffeine (chocolate included)
• Full-fat dairy items
• Mint varieties (such as peppermint and spearmint)
• Spicy, greasy, or fried foods
• Tomatoes and tomato-based sauces

You should also reach out to a healthcare provider if you experience any of the following:

• Trouble swallowing food
• Recurring heartburn
• Ongoing coughing or wheezing
• Unexplained weight loss
• Symptoms that worsen even after using treatments such as antacids or H2 blockers (like Pepcid AC)

Get immediate medical attention if heartburn occurs alongside:

• A burning or crushing sensation in your chest
• Blood in your stools
• Blood in your vomit

For patients whose symptoms overlap with abdominal hernia issues, learn more about abdominal hernia and heartburn treatment options that address both conditions together.
