The best thing to take for acid reflux depends on how often it happens and how severe it is. For occasional heartburn, an antacid or H2 blocker works fast and is usually enough. For frequent symptoms (more than twice a week), a proton pump inhibitor is the most effective option. But medication is only part of the picture, and the right choice involves matching the treatment to your pattern of symptoms.
Antacids: Fast but Short-Lived
Antacids, like calcium carbonate (Tums) or magnesium hydroxide (Milk of Magnesia), neutralize stomach acid that’s already been produced. They work within minutes, which makes them useful when you need immediate relief after a meal. The tradeoff is that they wear off quickly, typically within one to two hours, and they don’t prevent acid from being produced in the first place.
If your reflux is mild and happens only a few times a month, antacids are a reasonable first choice. They’re inexpensive, widely available, and don’t require a daily commitment. But if you find yourself reaching for them several times a week, that’s a sign you need something stronger.
H2 Blockers: The Middle Ground
H2 blockers, like famotidine (Pepcid), reduce the amount of acid your stomach produces by blocking histamine receptors on acid-producing cells. They take longer to kick in than antacids (usually 30 to 60 minutes) but provide relief that lasts significantly longer, often 8 to 12 hours.
If you experience two or fewer episodes of reflux per week and haven’t been diagnosed with any damage to your esophagus, H2 blockers are generally the best first-line choice. They’re also useful for nighttime reflux, since a dose before bed can suppress acid production through the night. Some people already taking a stronger medication add an H2 blocker at bedtime specifically for this reason. H2 blockers are also considered a safer option during pregnancy.
Proton Pump Inhibitors: The Strongest Option
Proton pump inhibitors (PPIs) like omeprazole (Prilosec) and lansoprazole (Prevacid) are the most powerful acid suppressors available over the counter. Rather than just reducing acid production, they directly block the pumps responsible for secreting acid into the stomach. A single dose suppresses acid output for 10 to 14 hours.
PPIs don’t provide instant relief. Their acid-suppressing effect takes at least five days to reach full strength, so they’re not useful for one-off episodes. They’re designed to be taken daily, typically once in the morning before eating. Over-the-counter PPIs are meant to be used for 14-day courses, repeated no more than once every four months.
If you have frequent or severe reflux, erosive esophagitis, or Barrett’s esophagus, a PPI is the most effective treatment. For these conditions, no other medication class comes close in terms of healing and symptom control.
Long-Term PPI Considerations
PPIs are safe for short courses, but prolonged use carries some risks worth knowing about. Long-term PPI therapy has been associated with reduced absorption of certain vitamins and minerals, an increased risk of bone thinning, and a higher rate of a specific type of intestinal infection. None of these risks are large enough to avoid PPIs when you genuinely need them, but they’re a good reason not to stay on them indefinitely without reassessing whether you still need them. If you’ve been taking a PPI for months, it’s worth checking with your doctor about whether stepping down to an H2 blocker might work.
Alginates: A Different Approach
Alginate-based products like Gaviscon work in a completely different way from acid suppressors. Instead of reducing or neutralizing acid, they form a gel-like raft that floats on top of your stomach contents. This physical barrier keeps acid from splashing up into your esophagus. Clinical evidence shows alginates are more effective than antacids for reflux, though slightly less effective than H2 blockers or PPIs. They’re a good option if you want to avoid acid-suppressing medications or need something you can use alongside them for extra protection after meals.
Lifestyle Changes That Actually Help
Medication handles symptoms, but certain lifestyle changes can reduce how often reflux occurs in the first place. A systematic review of dietary interventions found that 14 out of 16 studied approaches significantly improved reflux symptoms.
Low-carbohydrate diets, in particular, showed consistent benefits across multiple studies. Interestingly, the improvement wasn’t tied to weight loss: even short-term studies where participants didn’t lose significant weight still saw reduced symptoms. High-fat diets, on the other hand, were associated with worsening reflux. Diets high in fermentable carbohydrates (FODMAPs) increased the rate of lower esophageal sphincter relaxations, which is the primary physical mechanism behind reflux.
Beyond diet, elevating the head of your bed by six to eight inches helps keep acid in your stomach overnight. This is especially useful if you wake up with a sour taste or morning hoarseness. Lying flat allows gravity to work against you. Losing weight, if you carry extra weight around your midsection, also reduces the pressure pushing stomach contents upward. Eating your last meal at least two to three hours before lying down gives your stomach time to empty.
Ginger and Melatonin: Supplements With Some Evidence
A few natural supplements have clinical data behind them, though none are as reliable as conventional medications. Ginger speeds up stomach emptying and may reduce nausea and burning. In one trial, 1,650 mg of ginger powder per day led to significant improvements in reflux-like symptoms. Another found that over half of participants experienced meaningful relief from upper digestive complaints with ginger supplementation.
Melatonin is a more surprising option. At a dose of 3 mg taken at bedtime, it increased pressure in the lower esophageal sphincter, the muscle that’s supposed to keep acid from flowing upward. A separate trial using 5 mg at bedtime found that roughly 57% of participants had complete resolution of their symptoms, compared to almost no improvement in the placebo group. These are small studies, and melatonin isn’t a replacement for proven medications, but it may be worth trying if you prefer to start with something gentler.
Choosing the Right Treatment for Your Pattern
The “best” treatment for acid reflux maps directly to how often and how badly it affects you:
- A few times a month, mild burning after meals: antacids or an alginate product taken as needed.
- Once or twice a week, predictable triggers: an H2 blocker taken 30 to 60 minutes before eating or before bed.
- More than twice a week, or symptoms that disrupt sleep and daily life: a 14-day course of a PPI, combined with the lifestyle changes above.
If over-the-counter treatments aren’t controlling your symptoms after a couple of weeks, or if you notice chest pain, difficulty swallowing, pain while swallowing, unexplained weight loss, persistent vomiting, or any sign of bleeding (vomit that looks like coffee grounds, or dark tarry stools), those warrant a medical evaluation. These symptoms can signal complications that need more than self-treatment.
