Pepcid vs. Dexilant

See how Pepcid and Dexilant compare on approved uses, dosing, side effects, and cost.

Key Takeaways

  • Pepcid is an H2 blocker that starts working within about an hour and costs far less, while Dexilant is a stronger proton pump inhibitor built to heal erosive esophagitis.

  • Both drugs relieve GERD symptoms, but Dexilant only needs one dose a day and works no matter when you eat, while Pepcid is often taken twice daily.

  • Pepcid is sold over the counter and as a generic, while Dexilant is prescription-only and carries a much higher price tag without insurance.

Pepcid vs. Dexilant Drug Summary

Pepcid

Pepcid (famotidine) is an H2 blocker that reduces the amount of acid the stomach produces. It treats active duodenal and gastric ulcers, GERD, erosive esophagitis, and hypersecretory conditions like Zollinger-Ellison syndrome. It comes as a tablet taken once or twice daily depending on the condition being treated.

Dexilant

Dexilant (dexlansoprazole) is a proton pump inhibitor that blocks acid production at its source using a dual delayed-release capsule. It treats erosive esophagitis, helps keep it healed once it clears, and relieves symptoms of non-erosive GERD. It is taken once daily and works regardless of meal timing.

Pepcid vs. Dexilant Indications

Pepcid

Pepcid is FDA-approved to treat active duodenal and gastric ulcers, symptomatic non-erosive GERD, and erosive esophagitis confirmed by biopsy. It is also used for pathological hypersecretory conditions such as Zollinger-Ellison syndrome and to reduce the risk of ulcer recurrence.

  • Active duodenal ulcer

  • Active gastric ulcer

  • Symptomatic non-erosive GERD

  • Erosive esophagitis due to GERD

Dexilant

Dexilant is FDA-approved to heal all grades of erosive esophagitis and to maintain that healing over time. It also treats symptomatic non-erosive GERD in adults and adolescents 12 and older.

  • Healing of erosive esophagitis (all grades)

  • Maintenance of healed erosive esophagitis

  • Relief of heartburn

  • Symptomatic non-erosive GERD

Pepcid vs. Dexilant Pros and Cons

Pepcid

Pepcid works within about an hour, making it a practical option for occasional or mild symptoms, though it is not as strong as a PPI for healing erosive esophagitis. It is sold both over the counter and by prescription, and generic versions keep the cost low.

Pros

  • Available over the counter and generic

  • Starts working within about an hour

  • Roughly $10 to $100 per month without insurance, before savings programs

  • No food restrictions for timing

Cons

  • Less potent for healing erosive esophagitis

  • Often needs twice-daily dosing

  • Effect can wear off with regular use (tachyphylaxis)

  • Not approved for maintenance of healed erosive esophagitis

Dexilant

Dexilant's dual delayed-release formulation gives stronger, longer-lasting acid suppression, making it a better fit for healing erosive esophagitis. It costs significantly more than Pepcid and is not available as a generic or over the counter.

Pros

  • Stronger acid suppression for healing erosive esophagitis

  • Once-daily dosing regardless of meal timing

  • Approved for long-term maintenance of healed EE

  • Dual-release formula extends acid control

Cons

  • Roughly $270 to $470 per month without insurance, before savings programs

  • Not available over the counter

  • Long-term use linked to bone fracture risk

  • Small risk of C. difficile-associated diarrhea
