An increased risk of adverse cardiovascular events has been demonstrated with multiple cyclooxygenase-2 inhibitors, and this increased risk has led to the withdrawal from the market of all but one of these agents in the US. While several questions regarding the safety of coxibs remain, especially the role of dose in the increased risk and whether increased cardiovascular risk extends to traditional nonsteroidal anti-inflammatory drugs as well, clinicians should be cautioned about an increased possibility of adverse cardiovascular events in patients requiring therapy with coxibs.
