The fastest way to get rid of acid reflux is to take an over-the-counter antacid, which neutralizes stomach acid within minutes. If you don’t have one on hand, several physical and behavioral fixes can reduce symptoms in under 30 minutes. The best approach combines something that neutralizes or clears the acid with a position change that keeps it from creeping back up.
Over-the-Counter Options by Speed
Not all heartburn medications work on the same timeline. Antacids (the chewable tablets or liquid forms containing calcium carbonate or magnesium hydroxide) act the fastest because they directly neutralize acid already sitting in your stomach and esophagus. Relief typically starts within minutes.
H2 blockers like famotidine take about an hour to kick in. They work by reducing how much acid your stomach produces rather than neutralizing what’s already there, so they’re better suited for preventing the next wave of reflux than stopping one in progress. Proton pump inhibitors like omeprazole take one to four days to reach full effect, making them useless for immediate relief. If you’re in the middle of an episode right now, reach for an antacid first.
Loosen Your Waistband
This one sounds trivial, but the research is striking. A study published in Gastroenterology found that a snug waist belt increased acid reflux roughly eightfold compared to no belt. The pressure from tight clothing doesn’t just push more acid upward; it also dramatically slows your body’s ability to clear that acid once it reaches the esophagus. Without a belt, the esophagus cleared refluxed acid in about 23 seconds. With one, that jumped to over 81 seconds, giving the acid nearly four times longer to cause that burning feeling.
If you’re wearing a tight belt, high-waisted jeans, shapewear, or anything snug around your midsection, loosen or remove it. This is one of the simplest things you can do for immediate relief.
Change Your Position
Gravity is your best non-medical tool. If you’re lying flat, sit up or stand. If you’re already upright and the reflux is happening at night, elevate the head of your bed or use a wedge pillow angled between 30 and 45 degrees, raising your head six to twelve inches above your stomach. Stacking regular pillows doesn’t work as well because it bends you at the waist, which can actually increase abdominal pressure.
If you need to stay lying down, roll onto your left side. In this position, your esophagus and the muscular valve at its base sit higher than your stomach, so acid drains back down more quickly instead of pooling at the junction where it causes pain. Lying on your right side does the opposite, positioning the stomach above that valve and making reflux worse.
Chew Sugar-Free Gum
Chewing gum after a meal stimulates saliva production, and saliva naturally contains bicarbonate, which buffers acid. The extra saliva also physically washes acid back down out of your esophagus. This won’t work as powerfully as an antacid, but if you don’t have medication available, a piece of sugar-free gum can meaningfully reduce the burn. Avoid mint-flavored varieties, as mint can relax the valve between your esophagus and stomach, potentially making things worse.
Baking Soda as a Quick Fix
Half a teaspoon of baking soda (sodium bicarbonate) dissolved in a glass of cold water works as a makeshift antacid. It directly neutralizes stomach acid and can bring relief within minutes. You can repeat this every two hours if needed, but don’t exceed five teaspoons in a single day.
This is a short-term fix, not a routine one. Baking soda is extremely high in sodium, so it’s a poor choice if you have high blood pressure, heart disease, kidney disease, or if you’re on a sodium-restricted diet. It can also cause water retention and worsen swelling. For occasional, desperate moments when you have nothing else available, it works. For anything more, use a proper antacid.
Try Diaphragmatic Breathing
Your diaphragm does more than help you breathe. Part of it wraps around the lower esophagus and acts as a physical barrier against reflux. A meta-analysis in Annals of Palliative Medicine found that targeted breathing exercises strengthen this muscle, reduce acid reflux episodes, and improve the effectiveness of medication.
The technique is straightforward: sit or lie comfortably, place one hand on your chest and one on your belly, and breathe slowly so that your belly rises with each inhale while your chest stays relatively still. Breathe in through your nose for four to five seconds, then exhale slowly through pursed lips. Even a few minutes of this can help relax the area and reduce the pressure driving acid upward. Over weeks of regular practice, the anti-reflux barrier itself gets stronger.
What to Avoid During an Episode
Some common instincts make acid reflux worse. Don’t lie down right after eating; wait at least two to three hours. Don’t drink carbonated beverages, which increase stomach pressure. Avoid bending over or doing any activity that compresses your abdomen. Skip coffee, alcohol, and chocolate until the episode passes, as all three relax the valve that keeps acid in your stomach.
Eating more food to “absorb” the acid is another common mistake. A full stomach increases the number of reflux events and raises the pressure that pushes acid upward.
When It Might Not Be Acid Reflux
Chest pain from acid reflux and chest pain from a heart attack can feel alarmingly similar. Heartburn typically produces a burning sensation in the chest and upper abdomen that responds to antacids. Heart-related chest pain feels more like pressure, tightness, or squeezing, and it often radiates to the neck, jaw, back, or arms. If antacids don’t help within 15 minutes, if the pain spreads beyond your chest, or if you feel lightheaded or short of breath, call emergency services. The distinction matters enough that it’s worth erring on the side of caution.
