-Patients who have an abnormal liver test or who develop signs or symptoms of liver dysfunction should be evaluated for hepatic dysfunction.

Precautions

US BOXED WARNINGS: RISK OF SERIOUS CARDIOVASCULAR AND GASTROINTESTINAL EVENTS:
-Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction, and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use.
-This drug is contraindicated in the setting of coronary artery bypass graft (CABG) surgery.
-NSAIDs cause an increased risk of serious gastrointestinal (GI) 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 and patients with a prior history of peptic ulcer disease and/or GI bleeding are at a greater risk for serious GI events.
