Treating acid reflux starts with lifestyle changes like smaller meals and not lying down after eating, then adds antacids or acid reducers if needed.
Acid reflux happens when stomach contents travel the wrong direction into your esophagus. For occasional episodes, a few targeted habits and an over-the-counter medicine usually settle it. For chronic symptoms—two or more times a week over several weeks—you’re dealing with GERD, and the treatment plan shifts to prescription options and possibly testing. The right approach depends on how often symptoms hit and how severe they are.
Start With These Lifestyle Adjustments
Doctors recommend lifestyle changes as the first line of treatment for acid reflux in adults. These changes target the two main causes: too much pressure in the stomach and a relaxed lower esophageal sphincter that lets acid escape upward.
- Eat smaller meals. A full stomach pushes against the valve at the top of your stomach, forcing it open.
- Skip large or late meals. A big dinner followed by sleep is a recipe for nighttime reflux.
- Wait 2–3 hours before lying down after eating. Gravity is your friend while you’re upright.
- Raise the head of your bed 6–8 inches. Use blocks under the bedposts or a wedge pillow—extra pillows alone don’t work because they bend you at the waist.
- Lose weight if you’re overweight. Extra abdominal fat increases stomach pressure directly.
- Quit smoking. Tobacco relaxes the esophageal sphincter and increases acid production.
- Avoid tight clothing. Anything that squeezes your waist pushes stomach contents upward.
Trigger foods vary by person, but common offenders include alcohol, caffeine, chocolate, peppermint, fatty or spicy foods, citrus, and tomato-based dishes. Cut them out one at a time to find which ones affect you—there’s no need to give up everything at once. If your symptoms are mild and occasional, these habits plus an antacid may be all you need.
Over-the-Counter Medicine Options
When lifestyle changes aren’t enough, three classes of OTC medicine treat acid reflux. They work differently and are used at different stages.
| Medicine Class | Examples | How It Works |
|---|---|---|
| Antacids | Calcium carbonate products | Neutralize acid already in the stomach for fast, short-term relief |
| H2 blockers | Famotidine, cimetidine, nizatidine | Reduce acid production for 4–12 hours; good for planned meals |
| Proton pump inhibitors (PPIs) | Omeprazole, esomeprazole, lansoprazole | Block acid production most completely; best for healing the esophagus |
Antacids give quick relief but don’t stop acid from being made. H2 blockers reduce acid for half a day and work well taken before a triggering meal. PPIs are the strongest acid suppressors and help heal the esophageal lining, but they take a few days to reach full effect. For persistent symptoms, the Mayo Clinic’s GERD treatment guidance recommends PPIs as the main prescription approach. If OTC options haven’t helped after a few weeks, it’s time to see a doctor.
When Prescription Treatment or Surgery Is Needed
If nonprescription treatments don’t control symptoms within a few weeks, doctors prescribe stronger medicine or order testing. This gives the esophagus time to heal from acid damage.
Prescription-strength PPIs include esomeprazole, lansoprazole, omeprazole, pantoprazole, rabeprazole, and dexlansoprazole. Newer potassium-competitive acid blockers like vonoprazan and tegoprazan are also available.
Common Mistakes to Avoid
Most treatment failures come from a few repeatable errors. Lying down within a few hours of eating undoes the benefit of any medicine. Eating large meals stretches the stomach and overwhelms the esophageal valve. Wearing tight waistbands, smoking, and drinking alcohol all directly relax the valve that keeps acid down. And ignoring repeated symptoms instead of seeking evaluation allows untreated reflux to damage the esophagus over time.
