The fastest way to relieve acid reflux is to take a liquid antacid, which neutralizes stomach acid within minutes. If you don’t have one on hand, a half teaspoon of baking soda dissolved in a glass of water works similarly. Beyond that, several positioning tricks and habit changes can ease the burn quickly and keep it from coming back.
Liquid Antacids Work Within Minutes
Over-the-counter liquid antacids are the quickest option most people have access to. The active ingredients bind directly to acid in your stomach, raising the pH within minutes of swallowing. Liquid formulations act faster than chewable tablets because they spread across the stomach lining immediately. The relief is real but short-lived: the buffering effect lasts roughly 30 minutes, though pain relief can stretch to about two hours.
If you’re choosing between products at the pharmacy, look for ones that also contain alginate (often listed as “alginate” or “alginic acid” on the label). Alginates work differently from plain antacids. Instead of just neutralizing acid, they react with it to form a gel-like raft that floats on top of your stomach contents, physically blocking acid from splashing up into your esophagus. They start working right away and can be taken with a meal or immediately after one.
The Baking Soda Option
Plain baking soda (sodium bicarbonate) is a legitimate antacid that most people already have in the kitchen. The Mayo Clinic lists a dose of one-half teaspoon dissolved in a full glass of cold water, taken every two hours as needed. Do not exceed five teaspoons in a single day.
There are some important limits. Don’t use baking soda for more than two weeks straight, and don’t take it within one to two hours of other medications, since it can interfere with absorption. Avoid combining it with large amounts of milk. If you have high blood pressure, kidney disease, heart disease, or swelling in your legs, skip this remedy entirely. Sodium bicarbonate causes your body to retain water, which can worsen those conditions.
Change Your Position Right Now
Gravity is your simplest tool. If you’re lying flat, sit up or stand. That alone can reduce the amount of acid pooling at the junction between your stomach and esophagus. If you need to stay in bed, roll onto your left side. In that position, your esophagus and the muscular valve at its base sit higher than your stomach, so acid drains away from the opening rather than toward it. Right-side sleeping does the opposite and tends to make reflux worse.
Elevating your head and upper body also helps. A wedge pillow angled at 30 to 45 degrees, lifting your head six to twelve inches, is the standard recommendation. Stacking regular pillows doesn’t work as well because they bend you at the waist instead of creating a gradual incline, which can actually increase abdominal pressure.
Stop Eating and Loosen Up
If you’re mid-meal when reflux hits, stop eating. A full stomach increases internal pressure, which pushes acid upward. Tight clothing, especially anything snug around your waist or midsection, does the same thing. Unbuckling a belt or changing into loose pants can provide noticeable relief within minutes.
Avoid lying down for at least two to three hours after eating. If symptoms wake you from sleep and you ate within a couple of hours of bedtime, that’s likely the trigger. Getting upright, even just propped up in bed, will help acid clear from your esophagus faster.
Chew a Piece of Gum
Chewing gum stimulates saliva production, and saliva is mildly alkaline. Research published in the Annals of Otology, Rhinology & Laryngology found that gum chewing consistently raises pH levels in both the esophagus and throat. Bicarbonate gum (sometimes sold specifically for acid relief) produces a bigger effect than regular gum, but any sugar-free variety helps. Avoid peppermint-flavored gum, though, since peppermint relaxes the valve between your stomach and esophagus and can make things worse.
Foods and Drinks That Make It Worse
Several common foods directly relax the lower esophageal sphincter, the muscular ring that’s supposed to keep acid in your stomach. When it relaxes at the wrong time, acid escapes upward. The main culprits:
- Chocolate contains a compound called methylxanthine (similar to caffeine) that loosens this valve.
- Coffee, both regular and decaf, along with other caffeinated drinks, has the same relaxing effect.
- Peppermint, garlic, and onions all trigger valve relaxation as well.
If you’re in the middle of an episode, avoid all of these. Also skip carbonated drinks. The bubbles increase stomach pressure, which pushes acid upward. Even water can be a problem if you gulp large amounts quickly, since the sudden volume raises pressure inside your stomach. Small, slow sips are fine.
H2 Blockers for Slightly Slower but Longer Relief
If antacids wear off too quickly, H2 blockers (like famotidine, sold as Pepcid) offer a different approach. Instead of neutralizing acid that’s already there, they reduce how much acid your stomach produces. The tradeoff is speed: they take about an hour to kick in. That makes them less useful for acute “I need relief now” moments but better for preventing the next episode. If you know a trigger meal is coming, taking one 30 to 60 minutes before eating gives it time to work.
For immediate relief combined with longer protection, some people take a liquid antacid first and follow it with an H2 blocker. The antacid handles the current burn while the H2 blocker prevents a repeat over the next several hours.
When Chest Pain Might Not Be Reflux
Heartburn and heart attacks can feel remarkably similar. Even experienced doctors sometimes can’t tell them apart without testing. Typical heartburn produces a burning sensation in the chest or upper abdomen, usually after eating or while lying down, often accompanied by a sour taste or a small amount of liquid rising into the back of your throat. It generally responds to antacids.
Heart attacks don’t always involve the dramatic crushing chest pain you see in movies. Symptoms vary widely between people. If your chest pain comes with shortness of breath, radiates to your arm, jaw, or back, is accompanied by lightheadedness or cold sweats, or doesn’t improve at all with antacids, treat it as a potential cardiac event and call emergency services. This is especially important if you have risk factors like high blood pressure, diabetes, or a family history of heart disease.
