Instructor: Artem Cheprasov

Celecoxib can be used to good effect for many different problems. However, it's not without its own potential problems. Find out more in this lesson on this drug's side effects, dosage, and drug class.

Pain Relievers

If you've got some joint aches and pains, do you use a pain reliever? Maybe you reach for Advil, Aleve, or something else. These types of medications help relieve the painful inflammation associated with joint aches, like in cases of arthritis. One other medication used for much the same purpose is celecoxib, better known by its brand name of Celebrex. Let's learn more about this medication's drug class, dosage information, and potential side-effects.

Drug Class

Celecoxib belongs to a class of drugs known as NSAIDs or non-steroidal anti-inflammatory drugs. They are called this because steroids are medications that can stop the process of inflammation and even suppress much of the immune system in general. Inflammation is a part of your immune system, by the way, and it's responsible for a lot of the pain people with arthritis feel. Now, even though steroids can help relieve this inflammation, the problem with them is that they are very powerful drugs with potentially very bad side-effects.

So, scientists came up with non-steroidal drugs that help minimize the process of inflammation instead. NSAIDs aren't the most powerful pain relievers by any means but, when taken as directed by a doctor, are usually much safer than them.


Celecoxib is taken at different doses, depending on exactly what it's being used for. For instance, people with osteoarthritis might take 200 mg, by mouth, once a day. Osteoarthritis is a form of 'wear and tear' arthritis. This is different from rheumatoid arthritis, which occurs when the body's immune system attacks its own joints. In this case, a person might take 100-200 mg, by mouth, every 12 hours.

Celecoxib may also be used to treat menstrual pain/cramps, in which case it may be taken (initially) at a dose of 400 mg, by mouth. This dose is later reduced.

Finally, celecoxib can also be used to treat ankylosing spondylitis, which refers to arthritis that mainly affects the spine. In this case, the dose may be something like 200 mg, by mouth, once a day.

It's extremely important to note that people with liver and/or kidney disease may need to have these doses modified or they shouldn't take this medication at all! So always consult with a doctor first.

Side Effects

That's because, although generally safer than steroids, celecoxib does have its own potential for various side-effects. These side effects include:
