Serious problems from stomach ulcers, such as bleeding, are well-known complications in people treated with NSAIDs. Similar problems have occurred in people treated with Vioxx, although very rarely. The likelihood of stomach problems increases the longer you take drugs like Vioxx. However, even short-term treatment is not without risk. These problems can happen without any warning, but in some people may cause symptoms such as gnawing or burning stomach pain, black or tarry stools, or vomiting. If this happens, stop taking Vioxx and call your health care provider right away.

Check with your health care provider. Vioxx may not be right for you, if you:

have had ulcers or stomach bleeding
have had asthma, hives, or allergic-type reactions after taking aspirin or other NSAIDs
have severe kidney problems
have severe liver problems
are pregnant
