Pepcid vs. Zantac 360
See how Pepcid and Zantac 360 compare on approved uses, dosing, side effects, and cost.
Key Takeaways
Pepcid and Zantac 360 both contain famotidine, the same H2 blocker, but Pepcid comes in prescription strengths for diagnosed ulcers and GERD while Zantac 360 is an OTC option for occasional heartburn.
Pepcid follows a structured schedule taken for weeks at a time to treat a diagnosed condition, while Zantac 360 is taken as needed right before or after heartburn strikes.
Because they share the same active ingredient, side effects like headache and dizziness overlap, but only Pepcid's prescription label reports exact rates for how often they occur.
Pepcid vs. Zantac 360 Drug Summary

Pepcid vs. Zantac 360 Pros and Cons
Pepcid
Pepcid offers prescription-strength dosing that treats diagnosed ulcers, GERD, and esophagitis, which OTC famotidine isn't approved to do. It requires a doctor's visit for these longer, higher-dose regimens, and cost varies depending on dose and insurance coverage.
Pros
Treats diagnosed ulcers, GERD, and esophagitis
Higher-dose options for stronger acid control
Often covered by insurance when prescribed
Cons
Requires a doctor's visit for higher doses
Longer 6 to 12 week courses needed for healing
Can cost more, roughly $10 to $100 per month before insurance
Zantac 360
Zantac 360 offers the convenience of over-the-counter access for occasional heartburn, without needing a doctor's visit or prescription. It isn't approved to treat diagnosed ulcers or GERD, and its OTC label doesn't report exact side effect rates.
Pros
Available without a prescription
Simple as-needed dosing, no titration
Consistently affordable, roughly $8 to $15 per month
Cons
Only approved for occasional heartburn
Doesn't treat or heal underlying ulcers or GERD
OTC label doesn't report exact side effect rates
