Heartburn is a common condition experienced by millions of people worldwide. It occurs when stomach acid flows back into the esophagus, causing a burning sensation in the chest area. Over-the-counter (OTC) antacids are readily available and can provide quick relief from heartburn symptoms. However, with numerous options on the market, finding the right antacid for your needs can be overwhelming. In this article, we will discuss how to choose the right OTC antacids and heartburn relief.

Different Types of OTC Antacids

When selecting an OTC antacid, it is important to consider the different types available:

1. Calcium Carbonate antacids:

These antacids reduce stomach acid by neutralizing it. They provide quick relief but have a short duration of action. Examples include Tums and Rolaids.

2. Sodium Bicarbonate antacids:

Similar to calcium carbonate antacids, sodium bicarbonate antacids also neutralize stomach acid but can cause gas and bloating. Baking soda is a well-known sodium bicarbonate antacid.

3. Aluminum and Magnesium antacids:

These antacids work by reducing stomach acid and are more suitable for long-lasting relief. They are often combined to offset each other’s side effects. Brands like Maalox and Mylanta fall under this category.

4. H2 Blockers:

H2 blockers reduce the production of stomach acid and provide longer relief compared to antacids. Examples of H2 blockers available OTC include Pepcid and Zantac.

5. Proton Pump Inhibitors (PPIs):

PPIs are the strongest type of OTC medication for heartburn relief. They suppress the production of stomach acid for up to 24 hours. Prilosec and Nexium are popular examples of PPIs.

Factors to Consider

When choosing the right OTC antacid or heartburn relief medication, take the following factors into account:

1. Severity and frequency of symptoms:

If you experience mild and infrequent heartburn, calcium carbonate antacids may be sufficient. For more frequent and severe symptoms, H2 blockers or PPIs may be more effective.

2. Allergies or sensitivities:

Check the product’s ingredients to ensure you are not allergic to any of them. Some antacids contain ingredients like aspirin or sodium, which may cause adverse reactions in certain individuals.

3. Pre-existing medical conditions:

If you have kidney problems, certain antacids containing magnesium or aluminum may not be suitable. Consult with your doctor before choosing an antacid.

4. Possible drug interactions:

If you are taking any other medications, especially prescription drugs, consult with a healthcare professional to avoid potential interactions between the OTC antacid and your medications.

Tips for Using OTC Antacids

Here are some important tips for using OTC antacids effectively:

1. Follow the recommended dosage:

Read the instructions provided with the antacid and use it as directed. Do not exceed the recommended dosage unless instructed by a healthcare professional.

2. Be aware of side effects:

Antacids may cause side effects such as diarrhea or constipation. If these side effects persist or worsen, discontinue use and consult a doctor.

3. Avoid long-term use:

OTC antacids are designed for short-term relief. If you experience frequent or persistent heartburn, consult with a healthcare professional for a proper diagnosis and treatment plan.

4. Consider lifestyle changes:

Incorporating lifestyle changes like avoiding trigger foods, eating smaller meals, and maintaining a healthy weight can help reduce heartburn symptoms in the long run.


Choosing the right OTC antacids and heartburn relief depends on various factors, including the severity and frequency of symptoms, allergies or sensitivities, pre-existing medical conditions, and potential drug interactions. Understanding the different types of antacids available and following the proper usage guidelines can help alleviate heartburn effectively. However, if symptoms persist or worsen, it is essential to consult with a healthcare professional for a proper evaluation and personalized treatment plan.
