Several effective options can relieve acid reflux at home, ranging from over-the-counter medications to simple changes in how you eat and sleep. The right choice depends on whether you need fast relief right now or a strategy to prevent symptoms from coming back.
Over-the-Counter Medications
Three categories of medication are available without a prescription, and they work differently enough that picking the right one matters.
Antacids (Tums, Rolaids, Maalox) are the fastest option. They neutralize stomach acid on contact, so relief typically starts within minutes. The tradeoff is that they wear off quickly, usually within an hour or two. They work best for occasional, mild episodes.
H2 blockers (famotidine, sold as Pepcid) reduce the amount of acid your stomach produces. They take about 60 minutes to kick in, but relief lasts 4 to 10 hours. This makes them a good choice when you expect symptoms later, like taking one before a meal that usually triggers heartburn.
Proton pump inhibitors (omeprazole, lansoprazole) are the strongest acid suppressors available over the counter. They take one to four days to reach full effect, so they’re not useful for immediate relief. They’re designed for frequent heartburn (two or more days per week) and are typically taken in 14-day courses.
Alginate products (Gaviscon) work differently from all three. When the alginate meets stomach acid, it forms a gel “raft” that floats on top of your stomach contents. This physical barrier blocks acid from splashing up into your esophagus. It’s especially useful after meals, when a pocket of acid tends to sit near the top of the stomach.
Kitchen Remedies That Actually Work
Baking soda is a legitimate, fast-acting antacid. Mix half a teaspoon into a full glass of cold water and drink it. According to Mayo Clinic dosing, you can repeat this every two hours, but don’t exceed five teaspoons in a day. It neutralizes acid almost immediately, though the relief is short-lived. Avoid using it as a daily habit: the high sodium content can cause problems over time.
Ginger has real evidence behind it. A study in the World Journal of Gastroenterology found that ginger sped up gastric emptying, cutting the time it took the stomach to move food along from about 16 minutes (half-emptying time) to about 12 minutes. A stomach that empties faster gives acid less opportunity to push upward. Ginger tea or a small piece of fresh ginger before or after meals is a reasonable option.
Chewing sugar-free gum after a meal is surprisingly effective. It stimulates saliva production, and saliva is naturally alkaline. Research shows gum chewing consistently raises the pH in both the esophagus and throat, helping to wash acid back down. Bicarbonate-containing gum works even better than regular sugar-free varieties.
Apple cider vinegar, on the other hand, has no clinical evidence supporting it for heartburn. Harvard Health Publishing noted that despite its popularity online, no studies published in medical journals have tested it for reflux. Since it’s acidic itself, it could plausibly make things worse.
Eating Habits That Reduce Symptoms
When you eat matters as much as what you eat. People who lie down less than three hours after their last meal are over seven times more likely to experience reflux compared to those who wait four hours or more. That’s a striking difference from a single habit change. If you eat dinner at 7 p.m., staying upright until at least 10 p.m. makes a meaningful difference.
Smaller meals help because a full stomach puts more pressure on the valve between your esophagus and stomach. That pressure pushes acid upward. Eating four or five smaller meals instead of two or three large ones keeps that pressure lower throughout the day. Avoiding common triggers like fried foods, citrus, tomato-based sauces, chocolate, alcohol, and coffee can also help, though triggers vary from person to person. Tracking what causes your symptoms is more useful than following a generic avoidance list.
How You Sleep Changes Everything
Sleeping on your left side is one of the most effective free remedies for nighttime reflux. The anatomy is straightforward: when you lie on your left side, your esophagus sits above your stomach, so gravity keeps acid where it belongs. On your right side, the position flips and acid flows toward the esophageal opening more easily.
The clinical data backs this up convincingly. A systematic review found that left-side sleepers had significantly less acid exposure in the esophagus compared to right-side or back sleepers. One study counted total reflux episodes per sleep position and found 80 on the left side versus 102 on the back and 109 on the right. A randomized trial found that people trained to sleep on their left side had more reflux-free nights and reported meaningfully lower symptom scores after just two weeks.
Elevating the head of your bed by 6 to 8 inches also helps. Propping yourself up with pillows doesn’t work as well because it bends your body at the waist, which can increase abdominal pressure. Placing blocks or a foam wedge under the head of your mattress keeps your entire upper body on an incline.
Other Lifestyle Adjustments
Tight clothing around your midsection, including belts and high-waisted pants, increases pressure on your stomach and can push acid upward. Loosening your waistband is a small change that sometimes provides noticeable relief. Excess weight has the same effect on a larger scale: even modest weight loss can reduce reflux frequency.
Smoking weakens the muscular valve at the top of the stomach, making reflux more likely. If you smoke and have frequent heartburn, this is one of the more impactful changes you can make.
When Home Remedies Aren’t Enough
Acid reflux that happens more than twice a week, persists for several weeks despite home treatment, or disrupts your sleep regularly may be gastroesophageal reflux disease (GERD), which benefits from a more structured treatment plan. Certain symptoms signal something more serious and need prompt medical evaluation: difficulty swallowing, unintentional weight loss, vomiting, signs of gastrointestinal bleeding (like dark stools or vomiting blood), and unexplained anemia. These are considered alarm symptoms in clinical guidelines and typically lead to an endoscopy to rule out complications.
