Following coronary artery bypass graft surgery, patients administered parecoxib have a higher risk of adverse events, such as cardiovascular thromboembolic events (e.g., myocardial infarction and cerebrovascular accident), deep surgical infections or sternal wound healing complications.
Post-marketing Surveillance: In post-marketing experience, the following rare, serious adverse events have been reported in association with the use of parecoxib: circulatory collapse, erythema multiforme, Stevens-Johnson syndrome, renal failure, and hypersensitivity reactions including anaphylaxis and angioedema.
In post-marketing experience, in addition to the severe cutaneous adverse reaction erythema multiforme and Stevens-Johnson syndrome, toxic epidermal necrolysis has been reported in association with the use of valdecoxib and cannot be ruled out for parecoxib.
