  • CALDOLOR is contraindicated in the setting of coronary artery bypass graft (CABG) surgery [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS].

Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events [see WARNINGS AND PRECAUTIONS].
