The fastest way to neutralize acid reflux is to take a liquid antacid containing magnesium hydroxide and aluminum hydroxide, which begins working within minutes and lasts about 80 minutes in the esophagus. But if you don’t have antacids on hand, several home strategies can bring noticeable relief in under 30 minutes. Here’s what works, how quickly, and why.
Antacids: The Fastest Option
Liquid antacids combining aluminum hydroxide and magnesium hydroxide (the formula behind Maalox and similar products) have the quickest onset of any over-the-counter reflux remedy. In head-to-head testing, this combination worked faster than calcium carbonate (Tums) in most people and provided about 82 minutes of esophageal relief compared to 60 minutes for calcium carbonate. If you’re choosing between what’s in your medicine cabinet, liquid formulas tend to coat more quickly than chewable tablets.
Alginate-based products like Gaviscon work differently and can last longer. When the alginate meets stomach acid, it forms a foam “raft” that floats on top of your stomach contents and physically blocks acid from splashing upward. This raft forms within seconds of taking a dose and can stay intact in the stomach for several hours, making it a particularly good choice if you need relief at bedtime.
Baking Soda: A Kitchen-Cabinet Fix
Dissolving half a teaspoon of baking soda in a full glass of cold water creates a basic solution that neutralizes stomach acid on contact. You can repeat this every two hours if needed, but don’t exceed five teaspoons in a single day. The relief is fast, usually within five to ten minutes, though the taste is unpleasant.
This is strictly a short-term fix. Mayo Clinic guidelines advise against using baking soda for reflux for more than two weeks. The sodium load is significant, so it’s not appropriate if you’re watching your salt intake or managing high blood pressure.
Change Your Position Right Now
If reflux hits while you’re lying down, your body position is likely making things worse. Two changes help immediately:
- Stand or sit upright. Gravity alone pulls acid back down into your stomach. If you’ve been reclining on the couch or in bed, simply sitting up can reduce the burning within minutes.
- Roll to your left side. If you need to stay in bed, sleeping on your left side positions your esophagus above the level of your stomach, allowing acid to drain away more quickly. Right-side sleeping does the opposite, keeping the junction between your esophagus and stomach submerged in acid. The frequency of reflux episodes may not change dramatically, but the duration of each episode shortens because acid clears faster.
Elevating the head of your bed by about six inches (using a wedge pillow or blocks under the bed frame) creates a gentle slope that works all night. Stacking regular pillows is less effective because you tend to slide off them, and bending at the waist can actually increase abdominal pressure.
Chew Gum for 20 to 30 Minutes
Chewing gum after a meal is a surprisingly well-supported remedy. It increases your rate of swallowing, boosts saliva production, and raises the concentration of bicarbonate in your saliva, which is your body’s own acid neutralizer. Studies measuring esophageal pH show that gum chewing consistently raises pH levels in both the esophagus and throat. Sugar-free bicarbonate gum produces the biggest effect, but any gum helps. Larger pieces of gum stimulate more saliva than smaller ones. Aim for at least 20 minutes of chewing after eating.
Stop the Triggers That Got You Here
While you’re dealing with the burn, avoid anything that relaxes the muscular valve between your esophagus and stomach. Coffee is one of the biggest offenders. It drops the pressure in that valve by roughly 30 percent in healthy people, and the effect is even more dramatic in people who already have reflux, where valve pressure can drop by nearly 40 percent. This happens regardless of whether the coffee is acidic or pH-neutral, so switching to low-acid coffee doesn’t solve the problem.
Other common triggers to avoid during an active flare:
- Fatty or fried foods, which slow stomach emptying and keep acid production elevated longer
- Alcohol, which relaxes the esophageal valve similarly to coffee
- Chocolate and mint, both of which reduce valve pressure
- Carbonated drinks, which increase stomach distension and belching, pushing acid upward
If you ate a large meal recently, don’t lie down for at least two to three hours. A full stomach increases the pressure pushing against that valve, and gravity is the only thing working in your favor when the valve isn’t doing its job well.
Ginger: Modest but Real Benefits
Ginger speeds up the rate at which your stomach empties its contents into the small intestine. In one trial, people who took ginger had a stomach half-emptying time of about 12 minutes compared to 16 minutes with a placebo. That may not sound dramatic, but a stomach that empties faster produces less acid and creates less upward pressure on the esophageal valve. Ginger tea or a small piece of fresh ginger is the simplest approach. Avoid ginger ale, which is carbonated and often contains very little actual ginger.
When Fast Fixes Aren’t Enough
If you’re reaching for antacids more than twice a week, the problem has likely moved beyond occasional heartburn. Proton pump inhibitors remain the standard medical treatment for persistent reflux, though questions about long-term safety have made gastroenterologists more cautious about open-ended prescriptions.
Certain symptoms signal something more serious than routine reflux: difficulty swallowing, pain when swallowing, unintentional weight loss, vomiting blood, or black and bloody stools. These are considered alarm symptoms by the American College of Gastroenterology and typically lead to an upper endoscopy to rule out complications like strictures, ulcers, or precancerous changes in the esophageal lining.
