A burning sensation in your stomach is most often caused by excess acid irritating your stomach lining or esophagus, and several over-the-counter options can help within minutes to hours. The right choice depends on how often the burning happens, when it strikes, and how long it lasts. Here’s what works, how fast each option acts, and when the burning signals something that needs more attention.
Antacids for Quick Relief
Antacids are the fastest option. Products like Tums, Rolaids, and Maalox neutralize stomach acid directly rather than slowing its production, so they start working within minutes. The trade-off is that relief typically lasts only 30 to 60 minutes. Antacids work best for occasional, mild burning that comes and goes, especially after a heavy meal or a known trigger food.
If you’re pregnant, antacids are generally a first-line option, but some formulations aren’t suitable during pregnancy, so check with a pharmacist. One important note: don’t take antacids within two hours of folic acid or iron supplements, because they can block absorption of both.
H2 Blockers for Longer-Lasting Relief
If antacids wear off too quickly or you’re dealing with burning that returns predictably (before meals, at night), H2 blockers are a step up. Famotidine (sold as Pepcid AC) and cimetidine (Tagamet HB) reduce the amount of acid your stomach produces rather than just neutralizing what’s already there. That means they take a bit longer to kick in but last significantly longer, often 6 to 12 hours.
You can take them in two ways. For active symptoms, take one tablet with a glass of water. To prevent burning before a known trigger, take one tablet ahead of time. Famotidine can be taken 15 to 60 minutes before the food or drink that causes your symptoms, while cimetidine works if taken up to 30 minutes beforehand. Don’t exceed two tablets in any 24-hour period.
Proton Pump Inhibitors for Persistent Burning
Proton pump inhibitors (PPIs) like omeprazole (Prilosec OTC) and esomeprazole (Nexium 24HR) are the strongest acid-reducing option available without a prescription. They shut down acid production more completely than H2 blockers, but they’re not designed for instant relief. PPIs take one to four days to reach full effect and are meant for people dealing with frequent burning, typically two or more days per week.
The standard OTC course is 14 days. The American College of Gastroenterology recommends PPI courses of up to 8 weeks for acid reflux, with longer use reserved for specific, doctor-diagnosed conditions. If your burning doesn’t improve after a two-week OTC course, or keeps coming back after you stop, that’s a signal to get evaluated rather than just restarting the medication.
Foods and Habits That Make It Worse
Several common dietary triggers are worth identifying because avoiding them can reduce how often you need medication at all. The most consistent culprits are fatty or greasy foods, spicy dishes, caffeine, alcohol, carbonated drinks, and acidic foods like tomatoes and citrus. Eating too quickly or overeating in a single sitting also contributes, because a very full stomach pushes acid upward.
If your burning is worse at night, a bed wedge that tilts your entire torso (not just extra pillows under your head) reduces pressure on the valve between your stomach and esophagus. Propping up only your head and shoulders can actually make reflux worse by crimping your midsection. Eating your last meal at least two to three hours before lying down also helps.
Herbal Options With Some Evidence
A few natural remedies have a long history of use, though the clinical evidence behind them is thinner than for OTC medications. Deglycyrrhizinated licorice (DGL) is thought to help by increasing the protective mucous coating of your esophagus and stomach lining. It’s available as chewable tablets or liquid. Regular licorice can raise blood pressure, so the DGL form, which has the blood-pressure-raising compound removed, is the safer choice. Even so, it shouldn’t be used as a long-term daily habit.
Ginger root has been used for centuries as a digestive aid and may help settle mild stomach burning. Ginger tea or small amounts of fresh ginger are the most common forms. Neither DGL nor ginger is a substitute for proper evaluation if your symptoms are frequent or worsening.
What Burning Could Mean Beyond Acid
Most stomach burning is related to acid and resolves with the approaches above. But persistent or recurring burning, especially when your stomach is empty, can point to a bacterial infection called H. pylori. This bacterium inflames the stomach lining and can eventually cause ulcers. Most people with H. pylori don’t have symptoms, but when they do, the hallmark is a burning or aching pain in the stomach area that feels worse on an empty stomach. A simple breath test or stool test can detect it, and treatment involves a short course of antibiotics.
Signs That Need Prompt Attention
Certain symptoms alongside stomach burning are red flags that warrant fast medical evaluation rather than self-treatment:
- Difficulty swallowing or the sensation that food is getting stuck
- Unexplained weight loss you haven’t been trying for
- Blood in your stool or black, tarry stools
- Vomiting blood or material that looks like dark coffee grounds
- Severe, sudden stomach pain that doesn’t improve
- Unusual fatigue, dizziness, or fainting
These can indicate bleeding, an ulcer, or other conditions that need diagnosis and treatment beyond what over-the-counter options can address.
