GERD Medication List

A GERD medication list sorts every treatment option by drug class, so you can see at a glance what each one does. Antacids neutralize acid within minutes, H2 blockers cut acid production for 8-12 hours, and PPIs suppress it for a full day or more. Prokinetics and baclofen sit behind those three, for motility problems and for symptoms that survive maximum acid suppression.

Treatment escalates one class at a time. Patients start with the mildest option that controls their symptoms and move up when it stops working. A shared reference keeps that sequence consistent across your team, and it keeps patients clear on what they are taking and why.

This guide covers each class with generic and brand names, OTC versus prescription status, mechanisms of action, and typical dosing. It also comes with a printable checklist you can keep alongside your practice’s medication protocols.

Key takeaways

GERD medications fall into five classes: antacids (fast-acting), H2 blockers (moderate acid reduction), PPIs (strongest suppression), prokinetics (motility support), and baclofen (refractory cases).

OTC options include antacids, low-dose H2 blockers, and low-dose PPIs. Prescription options offer higher doses and specialized formulations for erosive esophagitis.

Antacids work within minutes but fade after 30-60 minutes, H2 blockers hold for 8-12 hours, and PPIs cover 24 hours or more.

Pabau’s prescription management software helps practices track GERD medication protocols, dosing histories, and follow-up reviews in one place.

What is a GERD medication list and why use one?

A GERD medication list is a structured clinical reference that groups the available medications by drug class, mechanism of action, and indication. It standardizes how a practice treats reflux and keeps prescribing inside evidence-based guidelines. It also supports patient education and gives intake forms a shared vocabulary for medication histories.

GERD occurs when stomach acid repeatedly flows back into the esophagus, causing inflammation and symptoms like heartburn and regurgitation. Left untreated, chronic acid exposure can damage the esophageal lining, a condition called erosive esophagitis. Medications either reduce acid production or neutralize the acid already there, which lets the lining heal.

The American College of Gastroenterology (ACG) ties medication selection to symptom severity, symptom frequency, and whether tissue damage has occurred. A centralized list keeps your team aligned on that step-wise approach. It also gives patients a plain answer when they ask what each medication is for.

How to use this reference in your practice

The list works as a clinical reference and as a patient education tool. Here are five practical steps for putting it to work in your workflow:

1. Review it with new patients. At intake, ask which class they are already taking and explain what it does. That conversation sets up your consultation.
2. Track medication histories. Log every GERD medication tried, with dose, duration, and outcome, in your patient medication records. This prevents duplicate prescribing and shows up patterns.
3. Explain OTC and prescription options. Show patients what they can buy without a prescription, and name the point at which a prescription-strength PPI becomes the right call.
4. Document prescribing decisions. When you escalate from one class to the next, record the clinical rationale. Future reviews then start from the reasoning rather than the guesswork.
5. Book the review before the patient leaves. Follow up 4-8 weeks after starting a PPI, and capture the outcome on a medication review template so the next decision is evidenced.

Complete GERD medication list by drug class

GERD medications fall into five classes. The table below gives each one a generic name, a common brand name, its mechanism, OTC or prescription status, and typical dosing. This is the core reference clinicians and patients work from.

The three acid-control classes differ more in how long they last than in how fast they start. That difference decides where each one belongs in a treatment plan.

Antacids: Fast-acting relief

Antacids chemically neutralize the acid already in the stomach. Relief arrives in 5-10 minutes, but it fades after 30-60 minutes. Common OTC brands include Tums (calcium carbonate), Maalox (magnesium hydroxide), and Rolaids.

They are not a chronic GERD treatment. Frequent use brings side effects, since magnesium causes diarrhea and calcium constipates, and antacids do nothing to heal esophageal inflammation. Their place is occasional heartburn, or a bridge while another class takes hold. H2 blockers start working within about an hour, while PPIs need 3-5 days to reach full effect.

H2 blockers: Moderate acid reduction

These H2 receptor antagonists cut acid production by about 60-70% and hold for 8-12 hours. The most common is famotidine (Pepcid), sold both OTC at 10 mg and by prescription at 20-40 mg. Cimetidine and nizatidine are the other options, though both are prescribed far less often today.

H2 blockers are well tolerated and suit mild-to-moderate GERD, particularly night-time symptoms. They are weaker than PPIs at healing erosive esophagitis. If a patient shows no improvement after 2-4 weeks on an H2 blocker, escalation to a PPI is usually the next step.

Proton pump inhibitors: Strongest acid suppression

PPIs block the proton pump enzyme that produces stomach acid. They suppress secretion by more than 90% and cover 24 hours or longer. The options are omeprazole (Prilosec), esomeprazole (Nexium), lansoprazole (Prevacid), pantoprazole (Protonix), rabeprazole (Aciphex), and dexlansoprazole (Dexilant). Most come in both OTC and prescription formulations.

PPIs heal erosive esophagitis better than any other class and are first-line for moderate-to-severe GERD. They typically require 3-5 days to reach full effect. Long-term use has been associated with vitamin B12 deficiency, hypomagnesemia, and higher fracture risk in some studies, though causality remains debated. That makes periodic review part of the prescription rather than an optional extra.

Prokinetic agents: When motility is the problem

Prokinetics such as metoclopramide and bethanechol strengthen the lower esophageal sphincter and speed up gastric emptying. They are adjunctive therapy, used when acid reduction alone is not enough or when motility dysfunction is driving the reflux. Metoclopramide carries a black box warning for tardive dyskinesia with long-term use, which limits its appeal.

Prokinetics are prescribed alongside an H2 blocker or a PPI rather than on their own. Evidence for their standalone efficacy in GERD is modest, and prescribing has declined in recent years.

Baclofen: Treatment for refractory GERD

Baclofen, a GABA agonist, is a prescription medication reserved for patients who fail high-dose PPI therapy. It reduces transient relaxations of the lower esophageal sphincter, which is the primary mechanism of GERD in many patients. Typical doses run from 5-20 mg three times daily.

Baclofen is off-label for GERD, and its side effects limit tolerability. Drowsiness, dizziness, and weakness are the common ones. It usually comes up when surgery is being evaluated, or when symptoms persist despite maximum medical therapy.

OTC GERD medications: What patients can buy without a prescription

Patients can treat reflux without a visit, which is why many arrive already medicated. The OTC shelf carries every antacid, plus low-dose H2 blockers such as famotidine 10 mg. Low-dose PPIs are there too, including omeprazole 20 mg and lansoprazole 15 mg. These suit occasional heartburn, not daily use beyond two weeks without medical guidance.

Make clear that OTC status says nothing about how long a medication should be taken. Chronic GERD needs a diagnosis to rule out complications, plus periodic review. Pair that advice with a written acid reflux plan, so patients know which triggers to avoid between appointments.

Prescription GERD medications and when escalation is needed

Moving up to prescription strength buys higher doses and formulations the OTC shelf does not carry. Prescription PPIs typically run 40-80 mg daily, and high-dose H2 blockers sit at 20-40 mg. Prokinetics and baclofen are prescription-only in every form.

Four situations call for escalation to prescription therapy:

• OTC antacids are needed more than twice a week.
• OTC H2 blockers or PPIs have failed after two weeks.
• Endoscopy confirms erosive esophagitis.
• Complications such as Barrett’s esophagus or a stricture develop.

Record which of those four triggered the change. A note of the reasoning is what makes the next review quick, and it is what a covering clinician needs most.

GERD medication side effects and safety considerations

Side effects track the class. Antacids cause diarrhea with magnesium and constipation with calcium. H2 blockers are well tolerated, though headache and fatigue turn up. PPIs rarely cause acute problems, but long-term use is associated with vitamin B12 deficiency, so monitoring matters. Metoclopramide carries a black box warning for tardive dyskinesia, and baclofen brings central nervous system effects.

Check current FDA drug labeling and ACG guidance before prescribing. Drug interactions need the same attention, since omeprazole reduces the effectiveness of clopidogrel.

How to manage GERD medication tracking in your practice

Managing reflux well depends on knowing what each patient has already tried. Without one shared record, the prescribing logic is lost between visits, and patients end up on duplicate or conflicting therapy.

Most of that record belongs on the patient file rather than in a spreadsheet, which is what software for GP practices is built to hold. Four habits keep it usable:

1. Capture the baseline. Record symptoms and current medications at the first visit, through your standard prescription management workflows.
2. Log every trial. Note the start date, the dose, the duration, and the outcome: resolved, improved, no change, or worse.
3. Review on schedule. Book the follow-up 4-8 weeks after any new medication, and assess whether symptoms are actually controlled.
4. Write down the rationale. When you move a patient up a class, record why, so the next clinician reads a decision instead of a guess.

How Pabau keeps GERD medication histories in one place

In most practices a reflux history lives in three places at once. Part of it sits in the consultation note, part on a paper intake form, and part in whoever prescribed last. At the six-week review, someone has to reconstruct what the patient already tried.

Practice management software like Pabau holds that history against the patient record. Intake forms feed straight into the chart, so the antacid a patient bought over the counter is logged before the consultation starts. Prescriptions, dose changes, and outcomes then stack up on the same timeline.

That turns escalation into a quick decision. A clinician opening the record sees which classes failed, at what dose, and for how long. Follow-up reminders go out on their own, so a four-week PPI review does not depend on anyone remembering to book it.

Track GERD protocols with confidence

Pabau’s prescription management system keeps medication histories, dosing, and follow-up reviews organized so your team stays coordinated on every patient’s GERD treatment plan.

Conclusion

Choosing between these classes comes down to how long a patient needs cover, not how strong the drug sounds. Occasional heartburn is an antacid problem. Symptoms that return every night, or esophagitis confirmed on endoscopy, need suppression that lasts a full day.

What usually slips is the record, not the prescribing. Write down what was tried, at what dose, and what happened, and the next review takes minutes instead of a fresh history. Book a demo to see how Pabau keeps GERD medication histories and follow-up reviews on one patient record.
