Celecoxib
Summary
Celecoxib is used to reduce pain, swelling and stiffness in conditions like arthritis, ankylosing spondylitis and menstrual cramps. It's also used for acute pain from injuries, dental pain or postsurgery pain, and to reduce the number of colon polyps in high-risk patients with Familial adenomatous polyposis.
Celecoxib works by selectively inhibiting the COX-2 enzyme. This reduces the production of prostaglandins, which cause pain, swelling and inflammation. Unlike traditional NSAIDs, Celecoxib spares the COX-1 enzyme, which protects the stomach lining, leading to fewer stomach-related side effects.
Celecoxib is taken orally, with or without food. For osteoarthritis, the usual adult dose is 200 mg once daily or 100 mg twice daily. For rheumatoid arthritis, it is 100-200 mg twice daily. For acute pain and menstrual cramps, an initial dose of 400 mg is recommended, followed by 200 mg if needed. Children with juvenile arthritis must have dosing based on weight and prescribed by a doctor.
Common side effects include stomach pain, nausea, diarrhea, heartburn, headache, dizziness, and fluid retention. Serious but rare risks include heart attack or stroke, kidney problems, and stomach ulcers or bleeding.
Avoid Celecoxib if you have a history of heart attack, stroke, severe high blood pressure, stomach ulcers, severe kidney or liver disease, are allergic to sulfa drugs, or are in the third trimester of pregnancy. Long-term use of Celecoxib may increase cardiovascular risks, so it should be used under medical supervision.
Indications and Purpose
How does Celecoxib work?
Celecoxib selectively blocks the COX-2 enzyme, reducing the production of prostaglandins, which cause pain, swelling, and inflammation. Unlike traditional NSAIDs (which block both COX-1 and COX-2), celecoxib spares COX-1, which helps protect the stomach lining, leading to fewer stomach-related side effects compared to ibuprofen or aspirin.
How does one know if Celecoxib is working?
If the medicine is effective, pain, swelling, and stiffness should gradually improve within a few days. For chronic conditions like arthritis, joint movement should become easier. If there is no relief after two weeks, or if symptoms worsen, consult a doctor for dose adjustments or alternative treatment options.
Is Celecoxib effective?
Yes, celecoxib has been clinically proven to reduce pain and inflammation effectively. Studies show it works as well as other NSAIDs like ibuprofen and naproxen but with a lower risk of stomach ulcers. However, long-term use may increase cardiovascular risks, so it should be used under medical supervision, especially in patients with heart disease.
What is Celecoxib?
Celecoxib is a nonsteroidal anti-inflammatory drug (NSAID) mainly used to reduce pain, swelling, and stiffness in conditions like arthritis, ankylosing spondylitis, and menstrual cramps. It works by selectively inhibiting the COX-2 enzyme, which reduces inflammation while minimizing stomach-related side effects. Unlike traditional NSAIDs, it has a lower risk of stomach ulcers but may increase cardiovascular risks with long-term use.
What is Celecoxib used for?
Celecoxib is prescribed for:
- Osteoarthritis and rheumatoid arthritis (reduces pain and inflammation in joints).
- Ankylosing spondylitis (helps with spine stiffness and pain).
- Menstrual cramps (dysmenorrhea) (relieves severe period pain).
- Acute pain from injuries, dental pain, or post-surgery pain.
- Familial adenomatous polyposis (FAP) (reduces the number of colon polyps in high-risk patients).
Directions for Use
For how long do I take Celecoxib?
The duration depends on your condition. For chronic arthritis, it may be taken long-term under medical supervision. For acute pain, such as after an injury or surgery, it is usually taken for a few days to weeks. It should not be used longer than necessary due to potential side effects like heart risks and stomach issues.
How do I take Celecoxib?

Try to take it at the same time every day for consistent effects. Avoid lying down for at least 10 minutes after taking it.
How long does it take for Celecoxib to start working?
Celecoxib starts working within 1–2 hours of taking the first dose. For conditions like arthritis, it may take several days to a few weeks of continuous use to achieve full benefits. If pain relief is not noticeable after a few weeks, consult a doctor to adjust the dosage or explore alternative treatments.
