celecoxib vs heparin
Side-by-side comparison of celecoxib and heparin. 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
7.2 Platelet Inhibitors Drugs such as NSAIDS (including salicylic acid, ibuprofen, indomethacin, and celecoxib), dextran, phenylbutazone, thienopyridines, dipyridamole, hydroxychloroquine, glycoprotein IIb/IIIa antagonists (including abciximab, eptifibatide, and tirofiban), and others that interfere with platelet-aggregation reactions (the main hemostatic defense of heparinized patients) may induce bleeding and should be used with caution in patients receiving heparin sodium.
Recommendation: Use these medicines together only with caution. Your healthcare provider should monitor you closely for any signs of bleeding.
Celecoxib (Celebrex) is a medicine that reduces pain and swelling. It belongs to a class of drugs called NSAIDs.
Heparin is a medicine that helps prevent and treat blood clots. It is given as an injection into a vein or under the skin.
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.
Heparin is used to prevent and treat blood clots in your veins and lungs. It can also prevent clots after surgery or if you have an irregular heartbeat called atrial fibrillation. Heparin can also treat blood clotting problems throughout your body and prevent clots during surgery, blood transfusions, or dialysis.
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.
Heparin works by stopping certain proteins in your blood from forming clots. It helps to thin your blood and prevent new clots from forming. It does not dissolve existing blood clots, but it can keep them from getting bigger.

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.
Heparin can cause serious bleeding, which can be fatal. It can also cause a severe reaction called heparin-induced thrombocytopenia (HIT), where your body attacks your own platelets. Make sure your doctor knows if you have ever had HIT. Using the wrong strength of heparin can also cause fatal bleeding.
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.
If you are pregnant, talk to your doctor about the risks and benefits of using heparin. Preservative-free heparin is recommended during pregnancy if available. It is not known if heparin passes into breast milk, so it is recommended to avoid breastfeeding while using this medicine.
How to Read This celecoxib vs heparin Comparison
celecoxib is classified in the COX-2 Selective NSAID drug class, while heparin sits within the Unfractionated Heparin 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 50,030 submissions while heparin has 3,646. 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 both drugs affect how your blood clots, with one thinning the blood and the other stopping platelets from clumping. this combination makes it much easier for you to bleed or bruise.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
