More than 60 million Americans get heartburn at least once a month, and when that burning hits, you want it gone fast. The quickest relief comes from neutralizing the acid already in your esophagus, either with an over-the-counter antacid or a simple home remedy, while you take steps to keep more acid from creeping up. Here’s what actually works, both in the moment and over time.
Fast Relief: What Works Right Now
If you’re in the middle of a heartburn episode, an over-the-counter antacid (like Tums or Maalox) is your fastest option. These work within minutes by directly neutralizing stomach acid, though the relief is relatively short-lived compared to other options.
If you don’t have antacids on hand, half a teaspoon of baking soda dissolved in a glass of cold water acts as a makeshift antacid. It’s effective in a pinch, but don’t exceed five teaspoons in a day or use it as a regular solution. It’s high in sodium and not meant for repeated use.
A surprisingly effective trick: chew a piece of sugar-free gum. Chewing gum roughly doubles your saliva production, and that extra saliva washes acid out of the esophagus significantly faster. In one study, acid clearance time dropped from about seven minutes to just over two minutes with gum-stimulated saliva flow. It won’t stop an intense episode, but it can help clear lingering discomfort.
Change Your Position
Gravity is either working for you or against you. If you’re lying down, sit up or stand. That alone can reduce the amount of acid pooling in your esophagus. Avoid bending over, which puts pressure on your stomach and pushes acid upward.
If heartburn strikes at night, sleeping on your left side helps acid clear from the esophagus faster than sleeping on your back or right side. Elevating the head of your bed with a wedge pillow also reduces nighttime symptoms. These two adjustments together can make a real difference for people who regularly wake up with a burning chest.
Know Your Trigger Foods
Certain foods relax the muscular valve between your stomach and esophagus (the lower esophageal sphincter) and slow digestion, letting food sit in your stomach longer. Both of these effects make acid reflux more likely. The most common culprits include fried and fatty foods, tomato-based sauces, citrus fruits, chocolate, peppermint, carbonated drinks, spicy foods with chili powder or black pepper, and high-fat meats like bacon and sausage.
You don’t necessarily need to avoid every item on that list permanently. Most people have a handful of personal triggers. Paying attention to which foods consistently cause problems for you is more useful than following a generic elimination list. Eating smaller meals and avoiding food within two to three hours of bedtime also reduces the frequency of episodes.
Over-the-Counter Medications Compared
If heartburn keeps coming back, it helps to understand the three categories of medication and how they differ in speed and duration.
- Antacids work the fastest, neutralizing acid already present in your stomach. They’re ideal for occasional, predictable heartburn but wear off relatively quickly.
- H2 blockers (like famotidine) take about an hour to kick in but reduce acid production for 4 to 10 hours. These are better if you know heartburn is coming, such as before a large meal.
- Proton pump inhibitors (PPIs) (like omeprazole) are the strongest option. They take one to four days to reach full effect, so they’re not useful for a sudden episode. They’re designed for frequent heartburn, typically taken daily for a set period.
PPIs remain the most effective medication for persistent acid reflux. However, long-term use has been linked to a modest increase in fracture risk and potential issues absorbing calcium and vitamin B12. The absolute risk is small, and for many people the benefits clearly outweigh those concerns, but PPIs work best as a targeted treatment rather than something you take indefinitely without reassessing.
Heartburn vs. Heart Attack
Heartburn and heart attacks can feel alarmingly similar, and even doctors sometimes can’t distinguish them based on symptoms alone. Typical heartburn produces a burning sensation in the chest or upper abdomen, often after eating or while lying down. It’s usually relieved by antacids and may come with a sour taste or a small amount of acid rising into the back of your throat.
A heart attack is more likely to feel like pressure, tightness, or squeezing in your chest that spreads to your neck, jaw, or arms. It often comes with shortness of breath, cold sweat, sudden dizziness, or unusual fatigue. Women are more likely than men to experience jaw or back pain, nausea, and shortness of breath as their primary symptoms rather than classic chest pain. If there’s any doubt, treat it as a heart attack and call emergency services. That’s not overcautious; it’s the right call.
When Heartburn Signals Something More
Occasional heartburn after a heavy meal is normal. Heartburn that happens twice a week or more may be gastroesophageal reflux disease (GERD), which benefits from a more structured treatment plan rather than just reacting to each episode.
Certain symptoms alongside heartburn point to something that needs medical evaluation: difficulty swallowing or pain when swallowing, unexplained weight loss, persistent vomiting, loss of appetite, vomit that contains blood or looks like coffee grounds, or stool that appears black and tarry. These can indicate complications from chronic acid exposure or other conditions that overlap with reflux symptoms.
