Celebrex (celecoxib) is a pain-relief medicine that lowers inflammation. It’s classified as a COX-2 inhibitor that works by blocking a substance in the body (COX-2) that causes pain and inflammation. Celebrex may treat mild to moderate pain and help relieve symptoms of several types of arthritis, including osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. It can also help with menstrual pain, short-term pain after injuries or medical procedures, and juvenile arthritis in children ages 2 and older.
Celecoxib comes as a capsule that's taken by mouth, typically once or twice daily. However, the exact dosage depends on the condition being treated. For osteoarthritis, the usual dose is 200 mg per day taken as a single dose or divided into 100 mg twice daily. For rheumatoid arthritis, the typical dosage is 100 to 200 mg twice daily. For acute pain or menstrual cramps, the recommended starting dose is 400 mg once, followed by an additional 200 mg if needed on the first day, then 200 mg twice daily as needed.
Doses up to 200 mg may be taken with or without food, but doses above 200 mg should be taken with food to improve absorption. The lowest effective dose should be used for the shortest duration needed to manage symptoms. Do not exceed the recommended dosage. Swallow the capsules whole with water rather than opening or crushing them.
The active ingredient in Celebrex is celecoxib.
Avoid taking or using this medication if any of the following apply:
Known hypersensitivity (allergic reaction) to celecoxib, sulfonamides, or any inactive ingredients of the drug
History of asthma, hives, or allergic-type reactions after taking aspirin or other NSAIDs
Use during the peri-operative period in the setting of coronary artery bypass graft (CABG) surgery
Advanced kidney disease
Active peptic ulcer disease or recent gastrointestinal bleeding
Pregnancy during the third trimester (starting at 30 weeks of gestation)
Common side effects of Celebrex include:
These side effects are generally mild and may occur early in treatment. Digestive symptoms are among the most commonly reported side effects, especially with longer-term use.
More serious side effects can include heart attack, stroke, gastrointestinal bleeding, kidney problems, liver injury, or severe skin or allergic reactions. The risk of serious cardiovascular or GI events may increase with higher doses or prolonged use. Contact a healthcare provider immediately if you develop chest pain, shortness of breath, black or bloody stools, severe rash, swelling of the face or throat, or sudden changes in urine output.
What is Celebrex used for?
Celebrex is a prescription nonsteroidal anti-inflammatory drug used to relieve pain, inflammation, and stiffness associated with conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute pain.
How does Celebrex work?
Celebrex works by selectively blocking the COX-2 enzyme, which plays a key role in producing substances that cause inflammation and pain. This selectivity helps reduce pain while being gentler on the stomach compared to some traditional NSAIDs.
How is Celebrex typically taken?
Celebrex is taken by mouth, usually once or twice daily depending on the condition being treated. It may be taken with or without food, although taking it with food can help reduce stomach discomfort.
How quickly does Celebrex relieve pain?
Pain relief may begin within a few hours of the first dose, but maximum benefit for chronic conditions may take several days to weeks of consistent use.
What are the most common side effects of Celebrex?
Common side effects include stomach pain, indigestion, diarrhea, gas, headache, and swelling of the hands or feet. Many people tolerate the medication well.
Does Celebrex increase the risk of heart problems?
Celebrex may increase the risk of heart attack or stroke, especially with long-term use or higher doses. The risk may be greater in people with existing cardiovascular disease.
Can Celebrex cause stomach or intestinal problems?
Although Celebrex is designed to be easier on the stomach than some NSAIDs, it can still cause ulcers, bleeding, or perforation of the stomach or intestines, particularly with prolonged use.
Can Celebrex be taken with other pain relievers?
Celebrex should not be combined with other NSAIDs unless directed. Certain pain relievers and blood-thinning medications may increase the risk of side effects.
Is Celebrex safe for long-term use?
Celebrex may be used long term for chronic conditions when benefits outweigh risks. Ongoing monitoring is often recommended to assess cardiovascular, kidney, and gastrointestinal safety.
Is Celebrex safe during pregnancy or breastfeeding?
Celebrex should generally be avoided during late pregnancy due to potential risks to the fetus. Use during early pregnancy or breastfeeding should be based on careful consideration of potential benefits and risks.
A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (e.g., different shape or color), as trademark laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
