Several options genuinely work for heartburn, ranging from fast-acting antacids that neutralize acid in seconds to lifestyle changes that can eliminate symptoms entirely. What works best depends on how often you get heartburn, how severe it is, and whether you need relief right now or a longer-term solution.
Fast Relief: Antacids
Antacids are the quickest fix. Effervescent sodium bicarbonate formulas can start neutralizing stomach acid in as little as 6 seconds. Chewable calcium-based tablets (like Tums) typically reach their full effect within about 30 minutes. The tradeoff is that relief is short-lived: antacids taken on an empty stomach last only 20 to 60 minutes. Taken after a meal, a standard dose can hold acid at bay for up to 2 hours.
How you take them matters. Powder and effervescent forms work faster than liquids, and chewable tablets outperform ones you swallow whole. In fact, swallowable antacid tablets showed almost no measurable effect in some comparisons, while chewable tablets and effervescent formulas maintained their acid-suppressing action in the esophagus for 40 to 45 minutes and in the stomach for up to 3 hours.
Alginate Products: A Physical Barrier
Alginate-based products (sold under names like Gaviscon) work differently from standard antacids. When they hit stomach acid, they form a gel “raft” that floats on top of your stomach contents and physically blocks acid from splashing up into your esophagus. A systematic review and meta-analysis found that alginates were significantly more effective than both placebo and standard antacids at resolving reflux symptoms, with more than four times the odds of symptom resolution compared to those alternatives. If antacids alone aren’t cutting it, an alginate formula is worth trying, especially for heartburn that hits after meals.
Longer-Lasting Medication
If you need relief that outlasts an antacid, acid-reducing medications work on a different timeline. Famotidine (Pepcid), available over the counter in 10 mg and 20 mg doses, blocks one of the signals that tells your stomach to produce acid. It takes longer to kick in, roughly 60 to 90 minutes, but its effect lasts 10 to 12 hours. That makes it a better choice when you know a trigger is coming (a big dinner, for example) or when you need overnight coverage.
For persistent heartburn happening multiple days a week, a 14-day course of a proton pump inhibitor (PPI) like omeprazole (Prilosec) offers the strongest acid suppression available without a prescription. PPIs don’t provide instant relief. They take several days to reach full effect because they work by gradually shutting down acid-producing pumps in the stomach lining. Guidelines suggest that people with fewer than three episodes of heartburn per week are the best candidates for a short OTC course. If symptoms return after completing the 14 days, that’s a signal to talk to a doctor rather than repeat the cycle indefinitely.
Sleeping Position for Nighttime Heartburn
Nighttime heartburn responds well to two positional changes. Elevating the head of your bed (using a wedge pillow or bed risers, not just extra pillows) keeps gravity working in your favor. Sleeping on your left side helps even more. When you lie on your right side, your esophagus sits below the level of your stomach, essentially letting acid pool at the opening. Flipping to your left side reverses this geometry: the esophagus sits above the stomach, making it harder for acid to travel upward. A systematic review and meta-analysis confirmed that left-side sleeping is associated with measurable improvement in reflux symptoms.
Weight Loss
Losing weight is one of the most effective long-term strategies, but it takes a meaningful amount. In a prospective study, losing less than 5% of body weight produced no significant change in reflux symptoms. Women saw improvement at 5 to 10% body weight loss, while men needed 10% or more before symptoms budged. Among people who had reflux at the start of the study, 65% achieved complete resolution of symptoms and another 15% had partial improvement. That’s an 80% response rate, better than most medications can claim over the long term.
Dietary Triggers to Reduce
Certain foods and drinks relax the muscular valve between your esophagus and stomach, making it easier for acid to escape upward. The ones with the strongest evidence behind them are high-fat meals, alcohol, chocolate, coffee, and citrus fruits. Large, high-fat meals are a particularly reliable trigger because fat both relaxes that valve and slows stomach emptying, keeping acidic contents sitting higher for longer. You don’t necessarily need to eliminate every trigger food permanently. Many people find that identifying their two or three worst offenders and reducing portion sizes makes a noticeable difference.
Baking Soda: A Cheap but Limited Option
Plain baking soda (sodium bicarbonate) dissolved in water is the most basic antacid you can make at home. The Mayo Clinic lists the dose as half a teaspoon in a glass of water every two hours, with a maximum of 5 teaspoons per day. It works fast, but it comes with real limitations. The high sodium content makes it a poor choice for anyone with high blood pressure, kidney disease, heart disease, or swelling in the legs and feet. It also shouldn’t be used regularly as a substitute for actual treatment. Think of it as an occasional, in-a-pinch option rather than a daily strategy.
Ginger and Other Natural Remedies
Ginger gets a lot of attention as a natural reflux remedy. It does appear to speed up gastric emptying, which could theoretically help by moving food out of the stomach faster. However, in clinical studies on digestive symptoms, heartburn improved by only about 12% with ginger supplementation, and that change was not statistically significant. Ginger may help with bloating and nausea more than it helps with acid reflux specifically. If you find that ginger tea settles your stomach after a meal, there’s no harm in it, but don’t count on it to replace proven options.
Signs That Need Medical Attention
Most heartburn responds to the strategies above. But certain symptoms alongside heartburn point to something that needs investigation: difficulty swallowing, unintentional weight loss, vomiting, signs of gastrointestinal bleeding (black stools or vomiting material that looks like coffee grounds), or anemia. The American College of Gastroenterology recommends endoscopy as soon as feasible when any of these alarm symptoms are present. Heartburn that doesn’t improve after a 14-day PPI course or keeps coming back also warrants a closer look.
