Pantoprazole vs. Zantac 360
See how Pantoprazole and Zantac 360 compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Pantoprazole is a prescription PPI that heals erosive esophagitis over weeks, while Zantac 360 is an OTC H2 blocker meant for occasional heartburn relief.
Zantac 360 acts within about an hour, but pantoprazole provides stronger, longer-lasting acid suppression for diagnosed GERD tissue damage.
Both drugs can cause headache, diarrhea, and nausea, but pantoprazole's long-term use carries added risks like bone fracture and vitamin B12 deficiency.
Pantoprazole vs. Zantac 360 Drug Summary
Pantoprazole
Pantoprazole is a proton pump inhibitor (PPI) prescribed to heal erosive esophagitis caused by GERD and to manage rare acid-hypersecretion disorders like Zollinger-Ellison syndrome. It comes as a delayed-release tablet, oral suspension, or IV injection, and is typically taken once daily for eight weeks or longer for maintenance.
Zantac 360
Zantac 360 (famotidine) is an over-the-counter histamine-2 (H2) receptor antagonist that relieves and prevents occasional heartburn caused by acid indigestion and sour stomach. It comes as a film-coated tablet taken as needed, with a 10 mg dose for typical symptoms and a 20 mg dose for stronger episodes.

Pantoprazole vs. Zantac 360 Indications
Pantoprazole
Pantoprazole is FDA-approved to treat and heal erosive esophagitis caused by GERD, and to manage pathological hypersecretory conditions like Zollinger-Ellison syndrome. It is not approved for on-demand relief of heartburn symptoms, since it works gradually over days to reduce stomach acid production.
Short-term treatment of erosive esophagitis from GERD
Maintenance of healing after erosive esophagitis treatment
Treatment of pathological hypersecretory conditions like Zollinger-Ellison syndrome
Approved for pediatric use in children 5 and older
Zantac 360
Zantac 360 is FDA-approved to relieve and prevent occasional heartburn linked to acid indigestion and sour stomach. It is meant for occasional use and is not approved for healing esophageal damage from GERD or for children under 12 without a doctor's guidance.
Relieves heartburn from acid indigestion and sour stomach
Prevents heartburn triggered by certain foods and drinks
Intended for occasional, short-term symptom relief
Not approved for use in children under 12 without medical guidance
Pantoprazole vs. Zantac 360 Pros and Cons
Pantoprazole
Pantoprazole offers stronger and longer-lasting acid suppression than OTC options, making it the standard choice for diagnosed GERD with tissue damage. It requires a prescription for most doses and needs several days to reach full effect, so it isn't suited for immediate symptom relief.
Pros
Heals erosive esophagitis, not just symptom relief
Approved for pediatric use starting at age 5
Available as IV, tablet, or oral suspension
Treats rare hypersecretory conditions like Zollinger-Ellison syndrome
Cons
Requires a prescription for most doses
Takes days to fully reduce acid production
Long-term use linked to bone fracture and B12 deficiency risk
Costs roughly $10 to $170 per month without insurance, before savings programs
Zantac 360
Zantac 360 works within an hour and is available without a prescription, making it convenient for occasional heartburn. It provides less potent acid suppression than a PPI and isn't intended for healing esophageal damage or long-term GERD management.
Pros
Available over the counter without a prescription
Starts working within about an hour for fast relief
Simple as-needed dosing for occasional symptoms
Costs roughly $8 to $15 per month without insurance, before savings programs
Cons
Not intended for healing esophageal tissue damage
No clinical advantage over generic famotidine (Pepcid AC)
Only approved for occasional heartburn, not chronic GERD
Must see a doctor if symptoms last more than 14 days
