What is celecoxib?
Celecoxib (also called Celebrex®) is used to treat acute pain. This medicine is one of a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). Celecoxib is available as a 100mg and 200mg capsule to be taken by mouth.
How to take celecoxib
- Celecoxib is usually taken one or two times a day.
- It is best to take this medicine with food or milk so it does not upset your stomach.
- If you cannot swallow the capsule, you may open it and pour the medicine into a teaspoon of applesauce. Stir the mixture well and swallow right away. Drink enough water to make sure you swallow all of the medicine.
- Do not take more than what your doctor told you to take. Taking more than you are told may raise your chance of very bad side effects.
- Do not take this drug for longer than you were told by your doctor.
- Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Any medicine that has been mixed with applesauce may be stored in a refrigerator and used within 6 hours.
- Missed doses:
- Take a missed dose as soon as you think about it.
- If it is close to the time for your next dose, skip the missed dose and go back to your normal time.
- Do not take 2 doses at the same time or extra doses.
An enzyme in the body called cytochrome P450 2C9 (CYP2C9) has the ability to break down certain medicines including celecoxib. A genetic test can be done to determine if your CYP2C9 breaks down medicines slower or faster than normal. If your body breaks down the medicine slower than normal, you should avoid taking celecoxib. For information about CYP2C9 and its effect on celecoxib, talk with your doctor or pharmacist, and see “Do you know… Cytochrome P450 2C9 (CYP2C9) and medicines.” For more details, go to www.stjude.org/pg4kds.
