The best treatment for heartburn depends on how often it happens and how quickly you need relief. For occasional flare-ups, an over-the-counter antacid works fastest, neutralizing stomach acid within minutes. For heartburn that keeps coming back, a stronger acid-suppressing medication or lifestyle changes will do more for you than popping antacids all day. Here’s how the options compare so you can pick the right one.
How the Three Main Medications Compare
Over-the-counter heartburn medications fall into three categories, each working differently and on a different timeline.
Antacids (like Tums, Rolaids, and Maalox) neutralize the acid already sitting in your stomach. They work within minutes, which makes them the go-to choice when you need fast relief after a heavy meal. The downside is they wear off quickly, typically within one to two hours, and they do nothing to prevent the next episode.
H2 blockers (like famotidine, sold as Pepcid) reduce the amount of acid your stomach produces. They kick in within about 30 minutes and keep working for 4 to 8 hours. That longer window makes them useful when you know heartburn is likely, such as before a meal that tends to trigger it. They’re also a solid option for nighttime heartburn since a single dose before bed can suppress acid for most of the night.
Proton pump inhibitors (like omeprazole, sold as Prilosec, or esomeprazole, sold as Nexium) are the strongest option. They block acid production more completely and for longer than H2 blockers. The American College of Gastroenterology considers them the medical treatment of choice for gastroesophageal reflux disease (GERD). The trade-off is they take one to three days of daily use to reach full effect, so they aren’t designed for immediate relief. You take them once a day, ideally 30 to 60 minutes before your first meal.
A practical approach: keep antacids on hand for the occasional flare-up, try an H2 blocker if you get heartburn a few times a week, and consider a two-week course of a PPI if symptoms are frequent or severe.
Long-Term PPI Use Has Real Trade-Offs
PPIs are effective, but they weren’t designed to be taken indefinitely. Long-term use has been linked to reduced absorption of certain vitamins and minerals, a higher risk of bone thinning, and an increased chance of a gut infection called C. difficile-associated diarrhea. None of these risks are enormous for any individual, but they add up over years. If you’ve been taking a PPI daily for more than a couple of months, it’s worth reassessing whether you still need it or whether a lower-strength option could work instead.
Alginates: A Lesser-Known Option Worth Trying
Alginate-based products (like Gaviscon Advance) work through a completely different mechanism than antacids. Instead of neutralizing acid, they form a lightweight gel “raft” that floats on top of your stomach contents and physically blocks acid from splashing up into your esophagus. One study found alginates more effective than standard antacids for treating reflux symptoms. They’re particularly helpful for heartburn that strikes when you lie down, since the raft stays in place regardless of position. They’re available over the counter and can be combined with other approaches.
Foods and Drinks That Make It Worse
Certain foods don’t just irritate your esophagus. They physically weaken the muscular valve between your stomach and esophagus, making it easier for acid to escape upward.
Peppermint is one of the most common culprits. It relaxes the smooth muscles throughout your digestive tract, which is why it helps with irritable bowel symptoms, but that same relaxation loosens the valve at the top of your stomach. Coffee has a similar effect, and caffeinated ground coffee stimulates more acid production than decaffeinated. Chocolate, fatty foods, and alcohol round out the usual list of triggers.
You don’t necessarily need to eliminate all of these permanently. Pay attention to which ones reliably set off your symptoms and cut back on those first. Eating smaller meals also helps, since a full stomach puts more pressure on the valve.
Weight Loss Has a Measurable Impact
Carrying extra weight around your midsection increases pressure on your stomach, which pushes acid upward. Losing weight is one of the most effective long-term strategies for reducing heartburn, and the research puts specific numbers on it. A large study found that a BMI reduction of about 3.5 points over time decreased the risk of frequent reflux symptoms by roughly 40%. Another hospital-based study found that losing 5 to 10% of body weight in women, and more than 10% in men, led to significant reductions in overall symptom scores. For someone weighing 200 pounds, that means losing 10 to 20 pounds could make a noticeable difference.
How You Sleep Matters
Gravity is your ally when managing nighttime heartburn, and position matters more than you might expect. A study of 57 people with chronic heartburn found that sleeping on the left side didn’t reduce the number of reflux events compared to sleeping on the right side or back. But acid cleared from the esophagus significantly faster when participants were on their left side. This is likely because of anatomy: when you’re on your left, your stomach hangs below the esophageal opening, making it harder for acid to pool there.
Elevating the head of your bed by 6 to 8 inches (using a wedge pillow or blocks under the bed frame, not just extra pillows) also helps by keeping acid in your stomach through gravity. Avoid eating within two to three hours of lying down.
Ginger and Baking Soda as Home Remedies
Ginger speeds up gastric emptying, helping food move through your stomach faster. Since a slow-emptying stomach gives acid more opportunity to reflux upward, this can reduce symptoms. Up to 3 to 4 grams per day is considered safe, though more than 6 grams can actually cause heartburn and reflux rather than relieve it. Ginger tea or small amounts of fresh ginger are the easiest ways to try this.
Baking soda (sodium bicarbonate) is a classic home antacid. The standard dose is half a teaspoon dissolved in a glass of water, taken after meals, and no more than about 5 teaspoons total in a day. It works quickly, but it comes with a significant amount of sodium. If you’re watching your sodium intake for blood pressure, heart, kidney, or liver reasons, baking soda is not a good choice. It’s fine as an occasional stopgap when you don’t have antacids on hand, but not something to rely on regularly.
Signs That Heartburn Needs Medical Attention
Most heartburn is uncomfortable but harmless. Certain symptoms, however, suggest that acid has already caused damage or that something more serious is going on. These include difficulty swallowing or a feeling that food is getting stuck behind your breastbone, vomiting blood (which can look like red clots or dark coffee grounds), black or tarry stools, unexplained weight loss, and chronic coughing or hoarseness caused by acid reaching your airway. Any of these warrants a prompt conversation with a doctor, not another trip to the antacid aisle.
