That burning sensation in your chest after a spicy meal or when lying down at night is all too familiar for millions of Americans. Heartburn affects about 60 million people in the United States monthly, with 15 million experiencing symptoms daily.
The good news is that numerous over the counter heartburn medicine options can provide relief. This comprehensive guide will help you understand what causes heartburn, compare the different types of medications available, and determine which might work best for your specific symptoms.
Understanding Heartburn: Causes and Symptoms
Heartburn occurs when stomach acid flows back up into your esophagus, causing that characteristic burning sensation in your chest or throat. Despite its name, heartburn has nothing to do with your heart—though its symptoms can sometimes be mistaken for heart problems.
Common causes of heartburn include:
- Eating large meals or eating too close to bedtime
- Consuming trigger foods like spicy, fatty, or acidic items
- Drinking alcohol, coffee, or carbonated beverages
- Smoking tobacco products
- Being overweight or pregnant
- Taking certain medications (like aspirin or ibuprofen)
Frequent heartburn (occurring more than twice a week) may indicate gastroesophageal reflux disease (GERD), a chronic condition that requires proper management. While occasional heartburn can be treated with over the counter heartburn medicine, persistent symptoms should be evaluated by a healthcare provider.
5 Types of Over the Counter Heartburn Medicine
There are several categories of over the counter heartburn medicine, each working differently to provide relief. Understanding these differences can help you choose the most appropriate option for your symptoms.
1. Antacids
Antacids work by neutralizing stomach acid to provide quick relief from heartburn symptoms. They’re best for occasional, mild heartburn and can start working within minutes.
Top Antacid Brands:
- Tums (calcium carbonate) – Fast-acting, available in various flavors and strengths
- Rolaids (calcium carbonate and magnesium hydroxide) – Neutralizes acid while providing calcium
- Maalox (aluminum hydroxide and magnesium hydroxide) – Combines ingredients for balanced relief
Pros
- Fast-acting relief (within minutes)
- Available in various forms (chewable tablets, liquids)
- Can be taken as needed
Cons
- Short duration of relief (2-3 hours)
- May cause constipation or diarrhea
- Not ideal for frequent heartburn
2. H2 Blockers (Histamine-2 Receptor Antagonists)
H2 blockers reduce the production of stomach acid by blocking histamine receptors in the stomach lining. They don’t work as quickly as antacids but provide longer-lasting relief.
Top H2 Blocker Brands:
- Pepcid AC (famotidine) – Provides relief for up to 12 hours
- Tagamet HB (cimetidine) – Reduces acid production for extended relief
- Zantac 360 (famotidine) – Reformulated version that replaced the original ranitidine formula
Pros
- Longer-lasting relief (8-12 hours)
- Can prevent heartburn when taken before meals
- Fewer side effects than some other options
Cons
- Takes 30-90 minutes to start working
- May interact with other medications
- Not recommended for continuous use beyond 14 days
3. Proton Pump Inhibitors (PPIs)
Proton pump inhibitors are the strongest over the counter heartburn medicine available. They work by blocking the final stage of acid production in the stomach, significantly reducing acid levels for extended periods.
Top PPI Brands:
- Prilosec OTC (omeprazole) – One daily pill provides 24-hour relief
- Nexium 24HR (esomeprazole) – Helps heal damage caused by acid reflux
- Prevacid 24HR (lansoprazole) – Treats frequent heartburn with once-daily dosing
Pros
- Most effective for frequent heartburn
- Once-daily dosing
- Can help heal esophageal damage
Cons
- Takes 1-4 days for full effect
- Not for immediate relief
- Should not be used for more than 14 days without doctor supervision
4. Combination Antacid/H2 Blockers
These products combine the quick relief of antacids with the longer-lasting effects of H2 blockers to provide both immediate and extended symptom relief.
Top Combination Brands:
- Pepcid Complete – Combines famotidine with calcium carbonate and magnesium hydroxide
- Tums Dual Action – Combines calcium carbonate with famotidine
- Gaviscon Dual Action – Combines antacid with alginate (forms a protective barrier)
5. Alginates
Alginates work differently from other heartburn medications. They form a foam barrier that floats on top of stomach contents, preventing acid from flowing back into the esophagus.
Top Alginate Brands:
- Gaviscon – Contains alginate and antacid components
- Gaviscon Extra Strength – Higher concentration for stronger symptoms
- Gaviscon Advance – Enhanced formula with additional protective properties

Safety Tips for Using Over the Counter Heartburn Medicine
While over the counter heartburn medicine is generally safe for most people, it’s important to use these medications properly to avoid potential side effects or complications.
Dosage Guidelines
- Never exceed the recommended dosage on the package
- For antacids, wait at least 2 hours between doses
- H2 blockers and PPIs should be limited to 14 days of continuous use unless directed by a doctor
- Take H2 blockers 30-60 minutes before meals for prevention
- Take PPIs 30 minutes before the first meal of the day
Medication Interactions
Heartburn medications can interact with prescription drugs and affect how they work. Always consult with a pharmacist or doctor if you’re taking:
- Blood thinners like warfarin
- Prescription medications for heart conditions
- Antibiotics
- Medications for osteoporosis
- Antidepressants
- Iron supplements
Special Considerations
Pregnancy and Breastfeeding
If you’re pregnant or breastfeeding, consult with your healthcare provider before using any over the counter heartburn medicine. Some options like calcium-based antacids may be safer than others during pregnancy.
Long-term PPI Use Concerns
Extended use of proton pump inhibitors (beyond 14 days) should only occur under a doctor’s supervision. Long-term use has been associated with increased risks of bone fractures, vitamin B12 deficiency, kidney problems, and certain infections.
When to See a Doctor Instead of Self-Medicating
While over the counter heartburn medicine can effectively manage occasional symptoms, certain situations require professional medical attention.
Seek Immediate Medical Attention If You Experience:
- Severe chest pain, especially if it spreads to your jaw, arm, or back
- Shortness of breath or wheezing
- Severe stomach pain
- Vomiting blood or material that looks like coffee grounds
- Black, tarry stools
Schedule an appointment with your doctor if you experience:
- Heartburn symptoms more than twice a week
- Symptoms that persist despite using over the counter heartburn medicine
- Difficulty swallowing or painful swallowing
- Persistent nausea or vomiting
- Unexplained weight loss
- Heartburn symptoms that have lasted for several years
These symptoms may indicate a more serious condition like gastroesophageal reflux disease (GERD), Barrett’s esophagus, or even esophageal cancer, which require proper diagnosis and treatment.
Lifestyle Changes to Reduce Heartburn
While over the counter heartburn medicine can provide relief, making certain lifestyle changes can help prevent heartburn from occurring in the first place.
Dietary Modifications
- Eat smaller, more frequent meals instead of large ones
- Avoid eating within 3 hours of bedtime
- Limit trigger foods like spicy foods, citrus, tomatoes, chocolate, and fatty foods
- Reduce or eliminate alcohol consumption
- Cut back on caffeine from coffee, tea, and sodas
- Choose lean proteins and complex carbohydrates
Behavioral Changes
- Maintain a healthy weight
- Quit smoking
- Elevate the head of your bed 6-8 inches
- Wear loose-fitting clothing around your waist
- Manage stress through relaxation techniques
- Stay upright for at least 2 hours after eating
Frequently Asked Questions
Can I take different types of heartburn medications together?
It depends on the specific medications. Antacids can generally be taken with H2 blockers or PPIs, but you should space them at least 2 hours apart. However, you should not combine different H2 blockers or different PPIs. Always consult with a pharmacist or doctor before combining medications.
How long should I wait before trying a different heartburn medication?
For antacids and H2 blockers, you should notice effects within hours. If they’re not working after 1-2 days of proper use, you might consider trying a different option. For PPIs, allow 3-4 days for full effect before determining if they’re working. If you’ve tried multiple options without relief, consult a healthcare provider.
Can children take over the counter heartburn medicine?
Some heartburn medications are approved for children, but dosages vary by age and weight. Always read the package label for age restrictions and consult with a pediatrician before giving any heartburn medication to children under 12. Never give adult formulations to children unless specifically directed by a doctor.
Is it safe to take heartburn medication daily?
Most OTC heartburn medications are not intended for daily use beyond 14 days. If you need daily relief for more than two weeks, you should consult with a healthcare provider, as this may indicate a more serious condition requiring different treatment approaches.
Can heartburn be a sign of something more serious?
Yes, persistent heartburn can be a symptom of gastroesophageal reflux disease (GERD), hiatal hernia, Barrett’s esophagus, or even esophageal cancer. If your symptoms are frequent, severe, or don’t respond to over the counter heartburn medicine, it’s important to see a doctor for proper diagnosis.
Finding the Right Over the Counter Heartburn Medicine for You
With so many options available, choosing the right over the counter heartburn medicine depends on your specific symptoms, their frequency, and your overall health situation. For occasional, mild heartburn, antacids may provide sufficient relief. For more frequent symptoms, H2 blockers or PPIs might be more appropriate.
Remember that while medications can effectively manage symptoms, combining them with lifestyle changes often provides the best long-term results. Always follow dosage instructions carefully, be aware of potential interactions with other medications, and consult a healthcare provider if your symptoms persist or worsen.
By understanding the different types of heartburn medications available and when to use them, you can make informed choices to find relief from uncomfortable heartburn symptoms and improve your quality of life.
