Precautions

US BOXED WARNING: RISK OF SERIOUS CARDIOVASCULAR AND GASTROINTESTINAL EVENTS
-Cardiovascular Thrombotic Events: NSAIDs may cause an increased risk of serious cardiovascular thrombotic events, including 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.
-Gastrointestinal (GI) Bleeding, Ulceration, and Perforation: NSAIDs cause an increased risk of serious 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 peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events.

CONTRAINDICATIONS:
-Known hypersensitivity to this drug (e.g., anaphylactic reactions and serious skin reaction), or any of the product excipients
-History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs; severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients
-Demonstrated allergic-type reactions to sulfonamides
-In the setting of coronary artery bypass graft (CABG) surgery

Safety and efficacy have not been established in patients younger than 18 years except for those 2 to 17 years with Juvenile Rheumatoid Arthritis in which safety and efficacy have been established for up to 6 months.
