The fastest way to relieve acid reflux is with a liquid antacid, which can neutralize stomach acid and ease the burning within minutes. Chewable tablets work nearly as fast. Beyond medication, several positioning tricks and household remedies can help within 5 to 15 minutes when you don’t have an antacid on hand.
Liquid Antacids Work Fastest
Liquid antacid preparations neutralize stomach acid more quickly than tablets. The buffering effect kicks in almost immediately after swallowing, though it typically lasts only about 30 minutes. That short window is usually enough to break the cycle of burning and let you get comfortable. If you’re choosing between a liquid and a chewable tablet at the pharmacy, the liquid will give you a slight speed advantage.
Alginate-based products (sold under brands like Gaviscon) take a slightly different approach. When the alginate mixes with stomach acid, it forms a foamy raft that floats on top of your stomach contents. This raft acts as a physical barrier, sitting between the acid pool and your esophagus so that if reflux does occur, the raft moves up instead of acid. This makes alginates especially useful for reflux that happens when you lie down or bend over.
Baking Soda as an Emergency Fix
If you don’t have an antacid at home, baking soda (sodium bicarbonate) is a reasonable short-term substitute. It directly neutralizes stomach acid on contact. The Mayo Clinic lists the adult dose as half a teaspoon dissolved in a full glass of water, taken no more than every two hours and no more than four teaspoons total per day.
This is strictly a once-in-a-while solution. Baking soda is high in sodium, so it’s a poor choice if you have high blood pressure, heart disease, kidney disease, or swelling in your legs and feet. It can also cause the body to retain water. Don’t give it to children under six, and don’t rely on it as a regular remedy.
Chewing Gum Clears Acid Surprisingly Well
Chewing a piece of sugar-free gum after eating is one of the simplest things you can do. It roughly doubles your saliva production, and that extra saliva washes acid back down out of the esophagus. In one study published in the journal Digestion, gum chewing reduced the time it took to clear acid from the esophagus by about 70%, dropping the average clearance time from nearly 7 minutes to just over 2 minutes. Any sugar-free variety works. Avoid mint-flavored gum if mint is one of your triggers.
Body Position Makes a Big Difference
Gravity is your ally. If reflux hits while you’re lying down, sitting upright or standing will help acid drain back into your stomach. Don’t just prop your head up with pillows, since that can actually increase pressure on your abdomen. Instead, elevate your entire upper body by placing a wedge pillow under your mattress or raising the head of your bed by 6 to 8 inches.
If you need to stay lying down, roll onto your left side. In that position, your esophagus and the muscular ring at its base sit higher than the level of acid in your stomach. This lets acid exit the esophagus more quickly and makes it harder for new acid to splash upward. Lying on the right side does the opposite, positioning the junction between your stomach and esophagus below the acid pool.
Avoid the Foods That Triggered It
This won’t fix what’s happening right now, but knowing your triggers prevents the next episode. Some foods cause reflux because they physically relax the muscular valve between your stomach and esophagus. Chocolate, coffee, alcohol, mint, garlic, and onions all have this relaxing effect in higher doses. When that valve loosens, acid escapes upward more easily.
Fatty foods are a separate problem. They increase acid production and slow digestion, keeping food in your stomach longer and giving acid more opportunity to escape. If you just ate a large, rich meal and the burn is building, don’t lie down for at least two to three hours. A slow walk can help move things along.
Ginger May Help if You Have It
Ginger supports faster gastric emptying, meaning food moves from your stomach into your small intestine more quickly. Once food clears the stomach, acid production decreases and there’s less material to reflux. A small piece of fresh ginger steeped in hot water as a tea is the most common way to use it. This isn’t as immediately powerful as an antacid, but it’s a reasonable option if you prefer something natural and have ginger in your kitchen. Avoid ginger ale, which is often carbonated and contains very little actual ginger.
Loose Clothing and Deep Breathing
Tight waistbands, belts, and shapewear increase pressure on your abdomen and can physically push acid upward. If reflux hits after a meal, loosening your belt or changing into something with an elastic waistband gives your stomach more room. This is especially helpful if you tend to get reflux after large meals when your stomach is distended.
Slow, deep diaphragmatic breathing (breathing into your belly rather than your chest) can also help. The diaphragm wraps around the base of the esophagus, and engaging it with slow breaths strengthens its ability to keep acid where it belongs. A few minutes of deliberate belly breathing won’t cure anything, but it can take the edge off while you wait for other remedies to work.
When Reflux Needs More Than Quick Fixes
Occasional reflux is common and usually harmless. But if you’re reaching for antacids more than twice a week, the problem likely needs a longer-term approach. Persistent reflux can irritate the lining of your esophagus over time.
Certain symptoms signal something more serious: difficulty swallowing, the sensation that food is getting stuck in your throat or chest, unintended weight loss, vomiting, or food regularly coming back up. If reflux is accompanied by any of these, the issue has moved beyond what quick remedies can address. Chest pain that feels like reflux but comes with shortness of breath or radiates to your arm or jaw needs emergency evaluation, since it can mimic a heart attack.
