For quick relief from indigestion pain, an over-the-counter antacid is usually the fastest option, working within minutes to neutralize stomach acid. If your discomfort is more persistent or predictable, stronger options like acid-reducing tablets can keep symptoms away for hours. The best choice depends on whether you need immediate relief, want to prevent pain before a meal, or are dealing with symptoms that keep coming back.
Antacids for Fast Relief
Antacids are the go-to for indigestion pain that’s happening right now. They work by neutralizing the acid already sitting in your stomach, and liquid forms act faster than tablets. The tradeoff is that their buffering effect only lasts about 30 minutes, even though the pain relief you feel can stretch closer to four hours.
The main types differ slightly in how they behave:
- Calcium-based (Tums, Rolaids): The most common chewable antacids. Effective and widely available, with the added benefit of a small calcium boost.
- Magnesium-based (Maalox, Mylanta): Fast-acting liquids, though magnesium can loosen stools if used frequently.
- Aluminum-based (Amphojel): Similar relief, but tends to cause constipation rather than loose stools.
- Combination products (Gaviscon): Blend aluminum and magnesium to balance out the digestive side effects of each.
- Sodium bicarbonate (Alka-Seltzer): Essentially baking soda in effervescent form. Works quickly but adds sodium to your diet, which matters if you’re watching salt intake.
One practical tip: if you take other medications, leave a gap of at least one hour before or four hours after taking an antacid. Antacids can interfere with how your body absorbs other drugs.
H2 Blockers for Longer-Lasting Relief
If antacids wear off too quickly or you want to get ahead of the pain before it starts, H2 blockers are the next step up. Instead of neutralizing acid that’s already there, they reduce how much acid your stomach produces in the first place. Common over-the-counter options include famotidine (Pepcid).
H2 blockers take about an hour to kick in, so they’re not ideal when you’re already in pain and need instant relief. Where they really shine is prevention. If you know a spicy meal or a big dinner is going to bother you, taking one 30 to 60 minutes beforehand gives it time to work before the food arrives. The effects last significantly longer than an antacid, carrying you through a meal and beyond.
A practical approach many people use: take an antacid for immediate relief while letting an H2 blocker build up in the background for sustained protection.
PPIs for Persistent Symptoms
Proton pump inhibitors are the strongest acid suppressors available over the counter. They block acid production more completely than H2 blockers, but they work on a different timeline. You won’t feel much difference on the first day. It takes one to four days of daily use to get the full benefit.
PPIs make sense when indigestion is a recurring problem rather than an occasional annoyance, particularly if H2 blockers aren’t providing enough relief. They’re designed for short courses of about two weeks at a time when used without a prescription.
Long-term PPI use (months to years) has been linked to some concerns, including a higher risk of certain gut infections, reduced bone density, and poor absorption of some vitamins and minerals. A large 2025 study across five Nordic countries found that long-term use likely does not increase stomach cancer risk, which had been an earlier worry. Still, if you find yourself reaching for PPIs regularly, that’s a signal to work with a provider on a longer-term plan rather than self-treating indefinitely.
Natural Approaches That Have Evidence
Peppermint oil has some research behind it for indigestion specifically. Studies have found that it speeds up gastric emptying, meaning food moves through your stomach faster rather than sitting there causing discomfort. In one study, participants who took peppermint oil with a meal showed significantly faster stomach emptying compared to those who ate the same meal without it. Look for enteric-coated capsules if you want to try this route, as they prevent the oil from releasing too early and potentially worsening heartburn.
Ginger is another commonly used option. It has a long traditional track record for nausea and stomach upset, and many people find it helpful as a tea after meals. The evidence base is smaller than for peppermint, but it’s generally well tolerated.
Habits That Reduce Indigestion
What you take matters, but so does what you do around meals. A large study tracked lifestyle factors that predicted who developed chronic acid-related symptoms, and five habits stood out: maintaining a healthy weight, not smoking, getting at least 30 minutes of moderate physical activity daily, limiting coffee, tea, and soda to two cups or fewer per day, and eating a diet rich in fruits, vegetables, whole grains, and lean proteins like fish and poultry.
Meal timing plays a role too. Eating smaller portions puts less pressure on the valve between your stomach and esophagus, and finishing your last meal at least two to three hours before lying down gives your stomach time to empty. If nighttime indigestion is your main issue, elevating the head of your bed by a few inches (using a wedge pillow or bed risers, not just extra pillows) can keep acid from creeping upward while you sleep.
Indigestion During Pregnancy
Pregnancy makes indigestion much more common, especially in the second and third trimesters, as the growing uterus pushes up against the stomach. Antacids are generally considered the safest first option. H2 blockers are also considered safe for most of pregnancy, though guidelines recommend avoiding them during the first trimester as a precaution. Diet and positioning changes (smaller meals, staying upright after eating) are worth trying first, since they carry no risk at all.
Warning Signs to Take Seriously
Most indigestion is uncomfortable but harmless. Certain symptoms, however, point to something that needs medical attention: blood in your stool, difficulty swallowing, persistent nausea and vomiting, or unexplained weight loss.
Indigestion can also occasionally mimic or overlap with heart-related symptoms. If your discomfort comes with a tight or clenching feeling in your chest, pain radiating to your jaw, arms, or upper back, shortness of breath, or unusual sweating, treat it as a potential emergency. These symptoms warrant immediate care regardless of whether you think the cause is your stomach or your heart.
