Side-by-side comparison of dexlansoprazole and methotrexate. Data from FDA drug databases (Orange Book, NDC Directory, recalls, shortages) covering 20,000+ approved drugs, plus CMS pricing; see our methodology.

minor Known Drug Interaction

Methotrexate Clinical Impact: Concomitant use of PPIs with methotrexate (primarily at high dose) may elevate and prolong serum concentrations of methotrexate and/or its metabolite hydroxymethotrexate, possibly leading to methotrexate toxicities. No formal drug interaction studies of high-dose methotrexate with PPIs have been conducted [see Warnings and Precautions (5.10)] . Intervention: A temporary withdrawal of dexlansoprazole may be considered in some patients receiving high-dose methotrexate.

Summary
dexlansoprazole

Dexlansoprazole (Dexilant) is a medicine that lowers stomach acid. It belongs to a class of drugs called proton pump inhibitors (PPIs).

methotrexate

Methotrexate is a drug that can treat certain cancers, rheumatoid arthritis, psoriasis, and other conditions. It works by slowing the growth of cells in the body.

What It Treats
dexlansoprazole

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.

methotrexate

Methotrexate can treat acute lymphoblastic leukemia, a type of cancer, in adults and children. It also treats mycosis fungoides, a skin lymphoma, in adults. Additionally, it treats relapsed or refractory non-Hodgkin lymphoma in adults. For non-cancer conditions, it treats rheumatoid arthritis in adults, polyarticular juvenile idiopathic arthritis (pJIA) in children, and severe psoriasis in adults.

How It Works
dexlansoprazole

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.

methotrexate

Methotrexate blocks an enzyme called dihydrofolate reductase. This enzyme is needed for cells to grow and multiply. By blocking this enzyme, methotrexate slows down the growth of cells, especially cancer cells and cells that cause inflammation in arthritis and psoriasis.

How to Read This dexlansoprazole vs methotrexate Comparison

dexlansoprazole is classified in the Proton Pump Inhibitor (PPI) drug class, while methotrexate sits within the Disease-Modifying Antirheumatic Drug (DMARD) class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.

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 methotrexate has 162,819. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known minor interaction flagged in FDA labeling, attributed to dexlansoprazole can cause methotrexate to stay in your body longer and reach higher levels than normal. this can increase the risk of harmful side effects from the methotrexate.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
