What it does

Celecoxib treats the symptoms of osteoarthritis and rheumatoid arthritis.

Common side effects

Abdominal pain, Diarrhea, Upset stomach

Key warnings

Celecoxib may increase your risk of serious heart problems like heart attack and stroke, which can be fatal.

How It Works

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.

How to Take It

Take celecoxib exactly as your doctor tells you. For osteoarthritis, you may take 200 mg once a day or 100 mg twice a day. You can take it with or without food. For children who cannot swallow capsules, you can mix the capsule contents with applesauce.

Pregnancy & Breastfeeding

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.

Missed Dose

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule.

Storage

Store celecoxib at room temperature, away from moisture and heat.

Serious Warnings

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.

Known Drug Interactions

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.

Mechanism: 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.

What to do: Your doctor should monitor you closely for signs of methotrexate toxicity while you are taking both drugs.

moderate diflunisal

NSAIDs and Salicylates Clinical Impact: Concomitant use of Celecoxib with other NSAIDs or salicylates (e.g., diflunisal, salsalate) increases the risk of GI toxicity, with little or no increase in efficacy [ see Warnings and Precautions (5.2) ] .

Mechanism: Both drugs are similar types of pain relievers that can harm the stomach lining. Taking them together increases the risk of stomach problems without helping your pain any more than one drug alone.

What to do: You should avoid taking these two medications together to prevent serious stomach or intestinal issues.

moderate heparin

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.

Mechanism: 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.

What to do: Use these medicines together only with caution. Your healthcare provider should monitor you closely for any signs of bleeding.

In the absence of data regarding potential interaction between pemetrexed and NSAIDs with longer half-lives (e.g., meloxicam, nabumetone), patients taking these NSAIDs should interrupt dosing for at least five days before, the day of, and two days following pemetrexed administration.

Mechanism: Taking two different pain medicines from the same class can increase the risk of side effects because there is no evidence that they are safe to use together.

What to do: You should talk to your doctor about stopping one of these medicines to avoid a dangerous interaction.

Diuretics Clinical Impact: Clinical studies, as well as post-marketing observations, showed that NSAIDs reduced the natriuretic effect of loop diuretics (e.g., furosemide) and thiazide diuretics in some patients. ( 7 ) Diuretics : NSAIDs can reduce natriuretic effect of furosemide and thiazide diuretics.

Mechanism: This pain medicine can reduce the ability of your water pill to remove salt and extra fluid from your body.

What to do: Your doctor may need to monitor you for signs that your water pill is not working as well as it should.

Celecoxib treats the symptoms of osteoarthritis and rheumatoid arthritis. Official labeling lists 12 commonly reported side effects, including Abdominal pain, Diarrhea, Upset stomach.

Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. For this drug, FAERS contains 97,043 voluntary reports.

Report counts do not establish causation — a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information further shape supply and switching decisions.
