About this medication
- Celecoxib is an anti-inflammatory medicine, known as an NSAID.
- It helps relieve pain, swelling, and stiffness from osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis.
- It is also used for short courses to treat moderate to severe pain, such as after an injury, surgery, or dental work.
- Celecoxib eases symptoms but does not cure arthritis or stop it from getting worse.
Relieves selected arthritis and acute-pain symptoms.
How to use it
- Swallow the capsule whole with a glass of water.
- You can take celecoxib with or without food.
- Take this medicine exactly as your healthcare professional tells you. The amount and how often you take it will be on your prescription label.
- Do not take celecoxib together with other anti-inflammatory pain relievers, such as ibuprofen or naproxen, unless your doctor tells you to.
If you miss a dose
- Take the missed dose as soon as you remember.
- If it is almost time for your next dose, skip the missed one and continue your regular schedule.
- Do not take two doses at once to make up for a missed one.
Use the lowest effective prescribed dose for the shortest necessary duration.
Pregnancy and breastfeeding
- Do not take celecoxib during the last three months of pregnancy.
- Talk to your doctor before using celecoxib earlier in pregnancy, as it may still carry risks to your baby.
- Do not breastfeed while taking celecoxib.
Avoid late pregnancy; use from 20 weeks needs specific advice. The Canadian reference contraindicates breastfeeding.
Before you use it
- Tell your healthcare professional if you have ever had an allergic reaction to celecoxib, other anti-inflammatory pain relievers, aspirin, or sulfa medicines.
- Tell your healthcare professional about any heart, kidney, liver, or stomach problems.
- Tell your healthcare professional if you have asthma or nasal polyps, especially if pain relievers have ever triggered breathing problems.
- Tell your healthcare professional if you are pregnant, trying to become pregnant, or breastfeeding.
- Tell the Care365 care team about all other medicines you take, especially blood thinners, other pain relievers, water pills, or blood pressure medicines.
Important warnings
- Celecoxib can increase the risk of a heart attack or stroke. This risk is higher with higher doses and longer use, and in people with heart disease or risk factors for it. Use the smallest dose that controls your symptoms for the shortest time needed.
- Celecoxib can cause serious stomach or intestinal bleeding or ulcers, sometimes without any warning signs. This risk is higher in older adults and people who have had stomach ulcers before.
- Do not take celecoxib if you are in the last three months of pregnancy, as it can harm your unborn baby.
- Stop taking celecoxib and get medical help right away if you notice a skin rash, especially with fever, blistering, or peeling skin.
Avoid sulfonamide/NSAID allergy, active bleeding, severe kidney/liver/heart disease and peri-bypass use.

Missed doses, storage and accidental exposure

Follow your own product’s missed-dose instructions. If you are unsure, ask the Care365 clinical team before taking an extra dose. Contraceptives, injections and modified-release medicines may need a specific plan.
