Dexilant
Nexium
Dexlansoprazole (Dexilant) is a medicine that lowers stomach acid. It belongs to a class of drugs called proton pump inhibitors (PPIs).
Esomeprazole (Nexium) is a drug that reduces stomach acid. It belongs to a class of drugs called proton pump inhibitors (PPIs).
This medicine can help heal damage to your esophagus (the tube connecting your mouth to your stomach). It can also help with heartburn caused by acid reflux. Dexlansoprazole can also treat heartburn from GERD, a condition where stomach acid flows back into your esophagus.
This medicine treats frequent heartburn. Frequent heartburn means you have heartburn 2 or more days a week. This medicine is not for immediate relief of heartburn. It may take 1 to 4 days to work fully.
Dexlansoprazole works by reducing the amount of acid your stomach makes. It does this by blocking a specific system in your stomach cells. This helps to heal damage caused by stomach acid.
Esomeprazole works by reducing the amount of acid your stomach makes. It blocks the proton pump in your stomach lining. This pump is responsible for producing stomach acid.

How to Read This dexlansoprazole vs esomeprazole Comparison
dexlansoprazole is classified in the Proton Pump Inhibitor (PPI) drug class, while esomeprazole sits within the Proton Pump Inhibitor (PPI) class. Because both drugs share the same classification, they are often considered interchangeable in theory, but clinical outcomes rarely track that cleanly. Both drugs are split between OTC and prescription status, which affects access and supervision.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, dexlansoprazole has 39,793 submissions while esomeprazole has 20,984. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. No direct interaction between these two drugs is listed in our FDA-derived dataset, though co-prescription still warrants pharmacist review. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot represent individual circumstances. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information. This registry does not provide medical, treatment, substitution, or medication-change directions for dexlansoprazole or esomeprazole.
