GERD Medication Comparison Tool
Compare prescription GERD medications based on your specific needs and preferences. This tool helps you understand the differences between PPIs, H2 blockers, antacids, and prokinetics to make an informed decision with your doctor.
Medication Class | Onset of Action | Duration | Typical Dose | Effectiveness | Safety Profile | Cost |
---|---|---|---|---|---|---|
Proton Pump Inhibitors (PPIs) | 1-2 hours | Up to 24 hours | Once daily | Most effective; heals esophagitis | Long-term use risks: B12/magnesium deficiency | Higher cost |
H2 Receptor Antagonists | 30-60 minutes | 6-12 hours | Twice daily | Moderate effectiveness | Generally safe | Moderate cost |
Antacids | Immediate | 2-3 hours | As needed | Symptom relief only | Overuse risks: electrolyte imbalances | Lowest cost |
Prokinetics | 30-60 minutes | Varies | As prescribed | For specific cases | Tardive dyskinesia risk | Moderate cost |
When the burn of heartburn keeps you up at night, most people first reach for an antacid. But occasional relief isn’t enough for many who live with Gastroesophageal Reflux Disease (GERD) is a chronic condition where stomach acid frequently flows back into the esophagus, causing irritation, pain, and long‑term complications. While lifestyle tweaks matter, the real game‑changer for many patients is the right GERD medication. This guide walks you through the prescription options, how they work, and when doctors typically choose each one.
Why Medications Matter in GERD Management
GERD isn’t just occasional heartburn; persistent acid exposure can lead to esophagitis, strictures, Barrett’s esophagus, and even an increased cancer risk. When lifestyle adjustments-like losing weight, avoiding trigger foods, or elevating the head of the bed-don’t bring symptoms under control, medication steps in to protect the lining of the esophagus and allow healing.
Prescription Drug Classes for GERD
Doctors have three main categories of prescription drugs at their disposal:
- Proton Pump Inhibitors (PPIs) are the most potent acid suppressors, blocking the final step of acid production in the stomach.
- H2 Receptor Antagonists reduce acid by blocking histamine‑driven secretion.
- Antacids neutralize acid already present in the stomach.
In some cases, doctors also add a Prokinetic like metoclopramide to improve esophageal motility.
Proton Pump Inhibitors: The Workhorse
PPIs are the go‑to for moderate‑to‑severe GERD and for healing erosive esophagitis. They work by irreversibly inhibiting the H⁺/K⁺‑ATPase pump in parietal cells, the final step in acid secretion.
Common PPIs include:
- Omeprazole (Prilosec)
- Esomeprazole (Nexium)
- Lansoprazole (Prevacid)
- Rabeprazole (AcipHex)
- Dexlansoprazole (Dexilant)
Typical dosing is once daily before breakfast. For severe cases, doctors may prescribe a higher dose or split the dose (morning and evening) to ensure 24‑hour acid control.
H2 Receptor Antagonists: The Secondary Option
H2 blockers like famotidine (Pepcid) or ranitidine (Zantac) block histamine receptors on parietal cells, reducing basal and nocturnal acid output. They act faster than PPIs but don’t suppress acid as completely, making them suitable for mild GERD, nighttime symptoms, or as step‑down therapy after a course of PPIs.
Typical dosing is twice daily, 30 minutes before meals, with a possible nighttime dose for breakthrough symptoms.

Antacids: Quick Relief, Not Long‑Term Control
Antacids (e.g., calcium carbonate, magnesium hydroxide) chemically neutralize existing acid. They’re ideal for occasional heartburn but provide no healing benefit for damaged esophageal tissue. Overuse can lead to electrolyte imbalances or kidney stones.
Prokinetics: When Motility Is Part of the Problem
If a patient’s LES (lower esophageal sphincter) tone is weak or esophageal clearance is slow, a prokinetic such as metoclopramide may be added. It enhances gastric emptying and increases LES pressure, reducing reflux episodes.
Because prokinetics carry a risk of tardive dyskinesia with long‑term use, they’re typically prescribed for short periods (up to 12 weeks) and only when other options haven’t fully controlled symptoms.
Choosing the Right Prescription: A Stepwise Approach
Most clinicians follow a step‑up algorithm:
- Start with lifestyle modifications and over‑the‑counter antacids.
- If symptoms persist, begin a standard‑dose PPI for 4-8 weeks.
- Re‑evaluate: healed esophagitis→step‑down to the lowest effective dose or switch to an H2 blocker.
- For refractory cases, consider double‑dose PPI, add a prokinetic, or evaluate for surgical options like Nissen fundoplication.
Regular follow‑up is crucial. Long‑term PPI use (>1 year) has been linked to nutrient malabsorption (B12, magnesium), increased infection risk, and possible kidney disease, so doctors aim to use the lowest effective dose.

Comparison of Prescription Options
Class | Onset of Action | Duration of Acid Suppression | Typical Dose | Pros | Cons |
---|---|---|---|---|---|
Proton Pump Inhibitor | 1-2hours | Up to 24hours | Once daily before breakfast | Most effective; heals erosive esophagitis | Potential long‑term nutrient deficiency; higher cost |
H2 Receptor Antagonist | 30-60minutes | 6-12hours | Twice daily before meals | Fast relief; useful for nighttime symptoms | Less potent; tolerance can develop |
Antacid | Immediate | 2-3hours | Chewable tablet as needed | Quick symptom relief; inexpensive | No healing effect; possible alkalosis, kidney stones |
Monitoring and Safety Tips
Regardless of the drug class, patients should be educated on the following:
- Take PPIs 30minutes before the first meal of the day.
- Do not crush or split delayed‑release capsules.
- Report persistent nausea, severe diarrhea, or unexplained weight loss to a provider.
- Have labs checked annually for magnesium, calcium, and vitamin B12 if on a PPI for>1year.
- Consider a bone density scan after prolonged PPI use, especially in post‑menopausal women.
When Prescription Medication Isn’t Enough
If symptoms remain uncontrolled after max‑dose PPI and adjunct therapy, surgeons may discuss a Nissen fundoplication-a laparoscopic procedure that reinforces the LES. Candidates typically have documented esophagitis, large hiatal hernia, or poor response to maximal medical therapy.
Frequently Asked Questions
How long does it take for a PPI to heal esophagitis?
Most patients see significant healing within 4-8weeks of consistent once‑daily dosing. Endoscopy is usually repeated after 8weeks to confirm resolution.
Can I stop a PPI suddenly?
Abruptly stopping a high‑dose PPI can cause rebound acid hypersecretion. Doctors recommend tapering the dose or switching to an H2 blocker over 1-2weeks.
Are PPIs safe for pregnant women?
PPIs are category B medications, meaning animal studies show no risk and human data are limited but reassuring. They are prescribed when benefits outweigh potential risks.
What is the difference between omeprazole and esomeprazole?
Esomeprazole is the S‑enantiomer of omeprazole, offering slightly higher bioavailability and a marginally longer half‑life. Clinically, the difference is modest.
Do antacids interact with other medications?
Yes. Calcium carbonate can bind antibiotics like tetracycline and reduce absorption of iron supplements. It’s best to separate dosing by at least 2hours.
Understanding the role of each medication class lets patients and clinicians pick the right tool for the right job, keep symptoms in check, and protect the esophagus from long‑term damage. With a clear treatment plan, most people with GERD can enjoy meals, sleep, and daily activities without the constant fear of that burning sensation.
