Celebrex is prescribed for acute pain, menstrual cramps, and the pain and inflammation of osteoarthritis and rheumatoid arthritis. It is a member of a new class of nonsteroidal anti-inflammatory drugs (NSAIDs) called COX-2 inhibitors. Like older NSAIDs such as Motrin and Naprosyn, Celebrex is believed to fight pain and inflammation by inhibiting the effect of a natural enzyme called COX-2. Unlike the older medications, however, it does not interfere with a similar substance, called COX-1, which exerts a protective effect on the lining of the stomach. Therefore, Celebrex may be less likely to cause the bleeding and ulcers that sometimes accompany sustained use of the older NSAIDs.
Celebrex has also been found to reduce the number of colorectal polyps (growths in the wall of the lower intestine and rectum) in people who suffer from the condition called familial adenomatous polyposis (FAP), an inherited tendency to develop large numbers of colorectal polyps that eventually become cancerous.
Most important fact about Celebrex
Like other NSAID medication, Celebrex could increase the chance of having a heart attack or stroke, possibly resulting in death. The risk is greater if you have heart disease or use NSAIDs for a long time. It’s important to discuss the risks and benefits of using Celebrex with your doctor and to use the lowest effective dose for the shortest amount of time possible.
Although Celebrex is easy on the stomach, it still poses some degree of risk—especially if you’ve had a stomach ulcer or gastrointestinal bleeding in the past. All NSAIDs, including Celebrex, can cause serious—and even life-threatening—ulcers and bleeding in the stomach and intestines. These side effects can happen without symptoms and may occur at any time during treatment. If you’ve ever had ulcers or stomach bleeding, make sure the doctor is aware of it. And be sure to alert the doctor if you develop any digestive problems or notice a change in your bowel movement (such as blood in the stool or black, sticky stools).
How should you take Celebrex?
Take Celebrex exactly as prescribed. You can take it with or without food.
–If you miss a dose…
Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Do not take 2 doses at the same time.
What side effects may occur?
Side effects cannot be anticipated. If any develop or change in intensity, inform your doctor as soon as possible. Only your doctor can determine if it is safe for you to continue taking Celebrex.
- More common side effects may include:
Abdominal pain, diarrhea, headache, indigestion, nausea, respiratory infection, sinus inflammation
Special information if you are pregnant or breastfeeding
Celebrex can harm a developing baby if taken during the third trimester, and its safety earlier in pregnancy has not been confirmed. Take it during pregnancy only if you feel the risk is justified.
It’s possible that Celebrex makes its way into breast milk (limited data from one subject indicated that the drug was excreted in human milk), and it could cause serious reactions in a nursing infant. If this drug is essential to your health, your doctor may advise you to discontinue breastfeeding.
