The consumption of alcohol and NSAID may increase the risk of gastrointestinal problem.
Cardiovascular Risk: NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may increase with duration of use. Patients with cardiovascular disease or risk factors for cardiovascular disease may be at greater risk.
Gastrointestinal Risk: NSAIDs cause an increased risk of serious gastrointestinal adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients are at greater risk for serious gastrointestinal events.
Renal Effects: Long-term administration of NSAIDs has resulted in renal papillary necrosis and other renal injury. Renal toxicity has also been seen in patients in whom renal prostaglandins have a compensatory role in the maintenance of renal perfusion. In these patients, administration of an NSAID may cause a dose-dependent reduction in prostaglandin formation and, secondarily, in renal blood flow, which may precipitate overt renal decompensation. Patients at greatest risk of this reaction are those with impaired renal function, heart failure, liver dysfunction, those taking diuretic and ACE inhibitors, and the elderly.
Discontinuation of NSAID therapy is usually followed by recovery to the pretreatment state.
Advanced Renal Disease: No information is available from controlled clinical studies regarding the use of "Cenex" in patients with advanced renal disease. Therefore, treatment with "Cenex" is not recommended in these patients with advanced renal disease. If therapy must be initiated, close monitoring of the patient's renal function is advisable.
