Side-by-side comparison of celecoxib and methotrexate. Data from FDA drug databases (Orange Book, NDC Directory, recalls, shortages) covering 20,000+ approved drugs, plus CMS pricing; see our methodology.
moderate Known Drug Interaction
Methotrexate Clinical Impact: Concomitant use of NSAIDs and methotrexate may increase the risk for methotrexate toxicity (e.g., neutropenia, thrombocytopenia, renal dysfunction). Celecoxib has no effect on methotrexate pharmacokinetics. Intervention: During concomitant use of celecoxib and methotrexate, monitor patients for methotrexate toxicity.

Celecoxib (Celebrex) is a medicine that reduces pain and swelling. It belongs to a class of drugs called NSAIDs.
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.
Celecoxib treats the symptoms of osteoarthritis and rheumatoid arthritis. It can also help with juvenile rheumatoid arthritis in children 2 years and older. Additionally, it is used for ankylosing spondylitis, acute pain, and menstrual pain.
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.
Celecoxib blocks a substance in the body that causes pain and swelling. It targets COX-2, an enzyme involved in inflammation. By blocking COX-2, celecoxib reduces inflammation and relieves pain.
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.

Celecoxib may increase your risk of serious heart problems like heart attack and stroke, which can be fatal. This risk may happen early in treatment and increases with longer use. You should not take celecoxib if you are having heart bypass surgery. Celecoxib can also increase the risk of serious stomach and intestine problems like bleeding, ulcers, and holes, which can be fatal. These problems can happen without warning. The elderly and those with a history of ulcers or GI bleeding are at higher risk.
Methotrexate can cause serious harm to an unborn baby, including death. If you are pregnant, you should not take this medicine for non-cancer conditions. If you are taking it for cancer, talk to your doctor about the risks. This medicine can also cause severe allergic reactions and other serious side effects that can be life-threatening. Contact your doctor immediately if you experience any signs of infection, lung problems, or kidney problems.
Using celecoxib after about 20 weeks of pregnancy can cause kidney problems in the baby and low amniotic fluid. Avoid using celecoxib after 30 weeks of pregnancy because it can cause the baby's heart to close too early. If you are trying to get pregnant, talk to your doctor, as celecoxib may affect fertility.
Methotrexate can cause birth defects or fetal death if taken during pregnancy for non-cancer conditions. If you are pregnant or plan to become pregnant, talk to your doctor. Do not breastfeed while taking methotrexate, as it can pass into breast milk and harm your baby.

How to Read This celecoxib vs methotrexate Comparison
celecoxib is classified in the COX-2 Selective NSAID 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, celecoxib has 50,029 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 moderate interaction flagged in FDA labeling, attributed to celecoxib can make methotrexate more harmful to your blood and kidneys. this happens even though the amount of methotrexate in your blood stays the same.. 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 celecoxib or methotrexate.
