Heartburn is a burning sensation in your chest caused by stomach acid flowing back into your esophagus, and the fastest way to get rid of it depends on how often it happens. For occasional flare-ups, an over-the-counter antacid like Tums or Rolaids can neutralize acid within minutes. For recurring heartburn, a combination of medication, dietary changes, and simple habit shifts can prevent it from coming back.
Fast-Acting Relief Options
Over-the-counter heartburn medications fall into three categories, and they work on very different timelines. Antacids (Tums, Rolaids, Mylanta) are the quickest option. They neutralize acid that’s already in your stomach, so you feel relief within minutes. The trade-off is that they wear off relatively fast, making them best for occasional, mild episodes.
H2 blockers like Pepcid AC take longer to kick in, typically one to three hours, but they suppress acid production for several hours afterward. They’re a better choice if you know a trigger is coming, like a heavy dinner, or if your heartburn tends to linger. You can take one before a meal to get ahead of it.
Proton pump inhibitors (PPIs) like Nexium 24HR, Prilosec OTC, and Prevacid 24HR are the strongest option, but they’re not designed for instant relief. They can take one to four days to reach full effect. PPIs work best for people dealing with heartburn multiple days per week and are meant to be taken as a short course, not on a one-off basis when you feel a burn.
Foods That Trigger Heartburn
Certain foods relax the muscular valve between your stomach and esophagus and slow digestion, which lets acid sit in your stomach longer and increases the chance it splashes upward. The biggest culprits are foods high in fat, salt, or spice: fried food, fast food, pizza, fatty meats like bacon and sausage, cheese, and processed snacks like potato chips. Chili powder, black pepper, and cayenne are common triggers too.
A second group of foods causes the same problem through different mechanisms. Tomato-based sauces and citrus fruits are highly acidic on their own. Chocolate and peppermint both relax the esophageal valve. Carbonated beverages increase pressure inside your stomach. You don’t necessarily need to eliminate all of these permanently. Keeping a mental note of which ones precede your worst episodes is often enough to identify your personal triggers.
Timing Your Meals Matters
Stop eating at least three hours before you lie down. There’s a straightforward physical reason: when your stomach is full and you recline, gravity can no longer help keep acid where it belongs. This single change, eating dinner earlier or pushing bedtime a bit later, eliminates nighttime heartburn for many people. Late-night snacking is one of the most common and most fixable causes of reflux during sleep.
Sleep Position and Nighttime Heartburn
If heartburn wakes you up at night, your sleeping position can make a real difference. Research from Harvard Health found that sleeping on your left side doesn’t reduce the number of times acid backs up into your esophagus, but it clears acid significantly faster compared to sleeping on your back or right side. The anatomy works in your favor: when you’re on your left side, your stomach sits below the esophageal opening, so acid drains back down more quickly.
Elevating the head of your bed by about six inches (using a wedge pillow or blocks under the bed frame, not just extra pillows) also helps by keeping your torso on a gentle incline. Combining left-side sleeping with elevation is the most effective approach for stubborn nighttime symptoms.
Home Remedies Worth Trying
Baking soda is one of the most accessible home remedies. Mix half a teaspoon into four ounces of warm water and drink it. It works as a basic antacid, neutralizing stomach acid on contact. Don’t repeat for at least two hours, and don’t exceed seven half-teaspoon doses in 24 hours (three if you’re over 60).
Ginger has well-documented digestive benefits. Boil one or two pieces of fresh ginger root in four cups of water, add honey or lemon if you like, and sip it. Keep total ginger intake under four grams per day. Chamomile tea is another option that can soothe the digestive tract. Steep one or two tea bags in boiling water for 10 minutes.
One important caution: peppermint, despite its reputation as a stomach soother, can actually make heartburn worse. It relaxes the esophageal valve, which is the exact mechanism that causes reflux in the first place. If your discomfort is acid-related rather than general indigestion, skip the peppermint tea.
Long-Term PPI Safety
If you use PPIs regularly, you may have seen alarming headlines about long-term risks. A large population study across five Nordic countries found no association between long-term PPI use and stomach cancer, which had been a persistent concern. That said, extended PPI use has been linked to other issues, including a higher risk of certain bacterial infections, reduced bone density, and poor absorption of some vitamins and minerals. The practical takeaway is that PPIs are safe and effective when you genuinely need them, but it’s worth periodically reassessing with a healthcare provider whether you still do.
Heartburn vs. Heart Attack
Heartburn and heart attacks can feel remarkably similar. Even experienced physicians sometimes can’t distinguish them based on symptoms alone. Typical heartburn produces a burning feeling in your chest, usually after eating or while lying down. It’s often accompanied by a sour taste in your mouth or a small amount of acid rising into your throat, and antacids generally relieve it.
Heart attack symptoms lean more toward pressure, tightness, or squeezing in the chest that may radiate to your neck, jaw, or arms. Shortness of breath, cold sweat, sudden dizziness, and unusual fatigue are additional warning signs. These symptoms are more common in people with high blood pressure, diabetes, high cholesterol, or a history of smoking. If you have persistent chest pain and aren’t sure it’s heartburn, call 911. If you’ve had an episode of unexplained chest pain that resolved on its own, bring it up with your doctor even after the fact.
Signs That Heartburn Needs Medical Attention
Occasional heartburn is extremely common and usually manageable on your own. But certain symptoms signal something more serious. Difficulty swallowing, unintentional weight loss, signs of gastrointestinal bleeding (like dark or bloody stools), and anemia are all red flags that point toward a possible complication of chronic reflux or another condition entirely. Heartburn that persists despite two weeks of daily OTC treatment also warrants a closer look from a provider.
