For most people with GERD, an over-the-counter proton pump inhibitor (PPI) taken once daily before a meal is the most effective starting point. The American College of Gastroenterology recommends an 8-week trial as the standard first step for heartburn and regurgitation. But PPIs aren’t the only option, and they’re not always necessary. Depending on how frequent and severe your symptoms are, the right approach could range from a simple antacid to a prescription medication, often paired with changes to how and when you eat.
Three Types of Acid-Reducing Medication
GERD medications fall into three main categories, each working differently and suited to different levels of symptoms.
Antacids neutralize stomach acid that’s already there. They work within minutes, which makes them useful for occasional flare-ups after a heavy meal, but the relief is short-lived. They don’t heal any damage to the esophagus and won’t prevent symptoms from coming back. Common active ingredients include calcium carbonate and magnesium hydroxide.
H2 blockers (like famotidine, sold as Pepcid) reduce the amount of acid your stomach produces. They take longer to kick in than antacids but last several hours. About 60% of people get symptom relief from H2 blockers. The downside: your body can develop tolerance over time, making them less effective. They also struggle to suppress the surge of acid your stomach produces after meals, which is when reflux tends to be worst. After 8 weeks of use, H2 blockers heal esophageal inflammation in roughly half of patients.
Proton pump inhibitors (like omeprazole, sold as Prilosec, or esomeprazole, sold as Nexium) block acid production at its final step, creating deep, long-lasting suppression around the clock, including after meals. About 83% of people get symptom relief, and PPIs heal esophageal damage at roughly twice the rate of H2 blockers at every time point studied. In fact, PPIs heal more damage in 2 weeks than H2 blockers do in 8 weeks. Tolerance has not been reported even with long-term use. You take them once daily, 30 to 60 minutes before your first meal.
How Long to Stay on a PPI
The standard recommendation is 8 weeks of daily PPI use. After that, if your symptoms have resolved and you don’t have erosive damage to the esophagus or Barrett’s esophagus, you should try to step down. That could mean stopping entirely or switching to on-demand use, where you take a PPI only when symptoms return and stop again once they settle. Many people find they can manage well this way rather than staying on daily medication indefinitely.
Long-Term PPI Safety Concerns
You’ve likely seen headlines linking PPIs to bone fractures, kidney disease, dementia, or heart problems. Here’s the context: every study raising these concerns has been observational, meaning it noticed that people taking PPIs also happened to have these conditions. None proved the PPIs actually caused them. The associations with dementia, kidney disease, and cardiovascular disease have been particularly inconsistent across studies, and many weren’t even designed to study PPIs in the first place.
The more plausible concerns relate directly to what PPIs do: suppress acid. With less acid in your stomach, you may absorb less calcium, magnesium, iron, and vitamin B12 over time. Reduced acid also slightly increases risk of certain infections, including pneumonia and C. difficile. These risks are generally small, but they’re a reasonable argument for not staying on PPIs longer than you need to.
Alginate Products: A Physical Barrier
Alginate-based products (like Gaviscon Advance, which is different from regular Gaviscon in the U.S.) work through an entirely different mechanism. When the alginate hits your stomach acid, it forms a gel “raft” that floats on top of your stomach contents and physically blocks acid from splashing up into the esophagus. A meta-analysis found that alginates were over four times more likely to resolve GERD symptoms compared to placebo or standard antacids. They’re particularly useful for post-meal reflux and can be combined with other treatments.
When Standard Treatment Doesn’t Work
A significant number of people continue to have symptoms despite taking a regular dose of PPI. For these refractory cases, a newer class of medication called potassium-competitive acid blockers (P-CABs) offers an alternative. Unlike PPIs, which need stomach acid to activate them, P-CABs work directly and immediately. They bind to the same acid-producing pumps in your stomach but don’t require an acidic environment to get started. In studies of people whose GERD didn’t respond to standard PPI doses, P-CABs performed as well as or better than doubling the PPI dose. Your doctor may suggest this option if you’ve given PPIs a proper trial without adequate relief.
Eating Habits That Drive Reflux
What you eat matters, but how and when you eat may matter even more. A systematic review of dietary and lifestyle factors found that eating a late-night snack was the single strongest predictor of GERD, making it roughly five times more likely. Eating quickly quadrupled the odds. Eating past the point of fullness nearly tripled them. Skipping breakfast was associated with about 2.7 times higher odds, possibly because it leads to larger, more acid-provoking meals later in the day. Even eating very hot foods nearly doubled the risk.
These aren’t exotic changes. Eating at a normal pace, stopping before you’re stuffed, avoiding food within a few hours of bedtime, and keeping portion sizes reasonable can meaningfully reduce how often acid pushes into your esophagus. Carrying excess weight around the abdomen also increases reflux by putting pressure on the stomach, so weight loss often helps.
Sleeping Position and Elevation
Nighttime reflux responds well to gravity. Raising the head of your bed by about 20 centimeters (roughly 8 inches), which creates an elevation angle of around 20 degrees, has been shown to reduce symptoms. You can use a wedge-shaped pillow or place blocks under the head of the bed frame. Stacking regular pillows doesn’t work as well because it bends your body at the waist instead of creating a gradual incline from hips to head.
Natural Remedies With Some Evidence
Most natural remedies for GERD lack strong clinical data, but two have shown promise in small trials.
Melatonin at 3 mg daily has been tested in randomized controlled trials and relieved GERD symptoms comparably to a standard PPI dose in one study. Adding sublingual melatonin to PPI therapy also improved heartburn, stomach pain, and quality of life more than the PPI alone. Melatonin appears to strengthen the muscular valve between the esophagus and stomach while also reducing acid secretion. Side effects were minimal in these trials.
Ginger at roughly 1,000 mg per day improved symptoms like fullness, early satiety, and upper abdominal pain in a four-week randomized trial. However, results across studies have been inconsistent, likely due to differences in ginger formulations and dosing. Trials specifically focused on GERD (rather than general indigestion) are still limited.
Symptoms That Need Immediate Attention
Most GERD is uncomfortable but not dangerous. Certain symptoms, however, signal something more serious and call for endoscopy rather than another bottle of antacids. These include difficulty swallowing, pain when swallowing, unintentional weight loss, loss of appetite, vomiting that won’t stop, and any sign of gastrointestinal bleeding (such as vomiting blood or dark, tarry stools). If you’ve been on optimized PPI therapy and your symptoms still aren’t controlled, that also warrants further investigation.
