For GERD, you have several options ranging from over-the-counter antacids for quick relief to prescription-strength acid suppressors for persistent symptoms. The right choice depends on how often you experience reflux and how severe it is. Occasional heartburn after a big meal is a different problem than daily burning that disrupts your sleep, and each calls for a different level of treatment.
Antacids for Quick, Short-Term Relief
Antacids are the simplest starting point. Products containing calcium carbonate (like Tums) or magnesium hydroxide (like Milk of Magnesia) work by directly neutralizing the acid already sitting in your stomach. They kick in within minutes, which makes them useful when heartburn hits unexpectedly. The tradeoff is that relief only lasts a few hours, so antacids work best for occasional flare-ups rather than daily symptoms.
Alginates: A Physical Barrier Against Reflux
Alginate-based products (sold under brand names like Gaviscon Advance) take a different approach. When the alginate mixes with your stomach acid, it forms a gel-like raft that floats on top of your stomach contents. This physical barrier keeps acid from splashing back up into your esophagus. At least one study found alginates more effective than traditional antacids for GERD relief. They’re a good option if your main problem is acid creeping up when you bend over or lie down.
H2 Blockers for Moderate Symptoms
If antacids aren’t cutting it, the next step up is an H2 blocker. Famotidine (Pepcid) is the most widely available option in this class. Rather than neutralizing acid after the fact, H2 blockers reduce the amount of acid your stomach produces in the first place. They take longer to work than antacids, usually 30 to 60 minutes, but provide relief that lasts significantly longer. The standard over-the-counter dose of famotidine is 20 mg, and many people take it twice daily.
H2 blockers are a reasonable middle ground: stronger than antacids, with fewer concerns about long-term use than the more powerful options below.
Proton Pump Inhibitors for Persistent GERD
Proton pump inhibitors, or PPIs, are the strongest widely used acid suppressors. Common options include omeprazole (Prilosec), lansoprazole (Prevacid), pantoprazole (Protonix), and esomeprazole (Nexium). Several are available over the counter.
PPIs shut down the acid-producing pumps in your stomach lining. Once a pump is blocked, it stays blocked until your body builds a replacement, which can take up to 36 hours. This is why PPIs are so effective but also why they take a few days to reach full strength. You won’t feel instant relief the way you would with an antacid. Most people notice a meaningful difference within two to four days.
A large Cochrane review covering nearly 37,000 patients found that PPIs healed erosive esophagitis and resolved symptoms faster than H2 blockers across the board. For people with moderate to severe GERD, especially those with visible damage to the esophagus, PPIs are the standard treatment.
Concerns With Long-Term PPI Use
PPIs are well-studied and effective, but long-term use has drawn some scrutiny. Research has flagged potential associations with kidney problems, bone fractures, and certain infections, particularly at higher doses. That said, an expert review from the American Gastroenterological Association noted there is no direct evidence of a causal link between PPIs and these outcomes. The current guidance is not to stop PPIs solely because of these associations if you have a clear reason to be on them.
If you and your doctor decide to stop a PPI after long-term use, be aware that your stomach may temporarily overproduce acid in response, a phenomenon called rebound acid hypersecretion. This can make symptoms flare for a short period. Either gradual dose tapering or stopping all at once are considered acceptable approaches, but knowing rebound is possible helps you avoid mistaking it for a sign that you still need the medication.
Newer Prescription Options
Vonoprazan (Voquezna) is a newer type of acid suppressor that works similarly to PPIs but with a key difference: it doesn’t need stomach acid to activate. PPIs require an acidic environment to “turn on,” which is why they work best when taken before a meal. Vonoprazan is active immediately and binds to acid pumps in a reversible way. It’s FDA-approved for treating erosive esophagitis and for heartburn from non-erosive GERD. This is a prescription-only medication, typically reserved for people who haven’t responded well to standard PPIs.
Lifestyle Changes That Reduce Reflux
Medication works best alongside a few practical adjustments. These changes can sometimes reduce symptoms enough to lower the dose you need or avoid medication altogether during mild stretches.
Elevating the head of your bed by 6 to 8 inches helps gravity keep acid in your stomach while you sleep. This means raising the actual bed frame or using a wedge pillow, not just stacking regular pillows (which tends to bend you at the waist and can make things worse). Sleeping on your left side also helps. Right-side sleeping appears to put more pressure on the valve between your stomach and esophagus.
Certain foods relax that valve or slow digestion, giving acid more opportunity to escape upward. The most consistent triggers include:
- Fried and high-fat foods, including fast food, bacon, sausage, and cheese
- Tomato-based sauces and citrus fruits
- Chocolate and peppermint
- Carbonated beverages
- Spicy foods, particularly chili powder and black pepper
You don’t necessarily need to eliminate all of these permanently. Many people find that a few specific items are their main triggers while others don’t bother them much. Keeping a simple food diary for a couple of weeks is the fastest way to identify your personal pattern.
Symptoms That Need More Than Self-Treatment
Most GERD responds well to the options above, but certain symptoms signal something that warrants a closer look. Difficulty swallowing, pain when swallowing, unexplained weight loss, vomiting blood, or black and bloody stools are all considered alarm symptoms. These don’t necessarily mean something serious is wrong, but they typically prompt an upper endoscopy to rule out complications like narrowing of the esophagus or other conditions that mimic GERD. If you’re experiencing any of these alongside your reflux, self-treatment with over-the-counter products isn’t the right path.
