Aciphex vs. Zantac 360
See how Aciphex and Zantac 360 compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Aciphex is a prescription PPI for serious acid conditions like erosive GERD, ulcers, and Zollinger-Ellison syndrome, while Zantac 360 is an OTC H2 blocker for occasional heartburn.
Aciphex requires a doctor's prescription and costs far more per month than the over-the-counter Zantac 360.
Both drugs can cause headache and constipation, but long-term Aciphex use carries added risks like bone fracture and C. difficile infection that Zantac 360 does not.
Aciphex vs. Zantac 360 Drug Summary
Aciphex
Aciphex (rabeprazole) is a proton pump inhibitor that lowers stomach acid production to heal erosive GERD, duodenal ulcers, and hypersecretory conditions like Zollinger-Ellison syndrome. It's a delayed-release tablet taken once or twice daily depending on the condition. It requires a prescription and is approved for adults and adolescents 12 and older.
Zantac 360
Zantac 360 (famotidine) is an H2 receptor antagonist sold over the counter to relieve and prevent heartburn from acid indigestion and sour stomach. It's a film-coated tablet taken as needed, either after symptoms start or before eating foods known to trigger heartburn. It replaced the original ranitidine-based Zantac, which was recalled over contamination concerns.

Aciphex vs. Zantac 360 Indications
Aciphex
Aciphex is FDA approved to heal and maintain healing of erosive GERD, treat duodenal ulcers, and manage excess acid production in conditions like Zollinger-Ellison syndrome. Combined with antibiotics, it also helps eradicate H. pylori infection. It's approved for adults and adolescents 12 and older, but not for younger children.
Healing of erosive or ulcerative GERD
Maintenance of GERD healing
Duodenal ulcer healing
H. pylori eradication with antibiotics
Zantac 360
Zantac 360 is approved to relieve heartburn caused by acid indigestion and sour stomach, and to prevent it when taken before eating known trigger foods or drinks. It's meant for occasional symptoms rather than diagnosed conditions like erosive GERD or ulcers. It isn't recommended for children under 12 without a doctor's guidance.

Aciphex vs. Zantac 360 Pros and Cons
Aciphex
Aciphex is a prescription-only proton pump inhibitor built for more severe or hard-to-treat acid conditions, including erosive GERD, ulcers, and hypersecretory disorders. Because it requires a prescription and closer medical oversight, it costs significantly more than over-the-counter options meant for occasional heartburn.
Pros
Treats serious conditions like erosive GERD, ulcers, and Zollinger-Ellison syndrome
Available in higher prescription-only doses for hard-to-control acid conditions
FDA approved to help eradicate H. pylori when combined with antibiotics
Once-daily dosing covers most approved uses
Cons
Requires a prescription to obtain
Roughly $658 to $1,536 per month without insurance, before savings programs
Long-term use carries risk of bone fracture and low magnesium
Contraindicated with the HIV medication rilpivirine
Zantac 360
Zantac 360 is an over-the-counter H2 blocker designed for occasional heartburn, not for healing ulcers or erosive GERD. It's inexpensive and easy to access without a prescription, but it lacks the potency and broader FDA-approved indications that make Aciphex suitable for more serious acid-related conditions.
Pros
Available over the counter without a prescription
Roughly $8 to $15 per month, far less costly than prescription PPIs
Can be taken as needed right before trigger foods or meals
Familiar, well-tolerated safety profile at OTC doses
Cons
Only approved for occasional heartburn, not erosive GERD or ulcers
Not intended for long-term or high-strength acid suppression needs
Provides symptom relief only, not a healing therapy
Should not be combined with other famotidine or H2-blocker products
