History of or active GI disease eg, ulceration, bleeding or inflammatory conditions; sulfonamide allergy. Monitor BP closely during initiation & throughout course of therapy; patient w/ symptoms &/or signs of liver dysfunction or in whom abnormal LFT has occurred, for evidence of development of more severe hepatic reaction while on therapy.

Increased risk of bleeding w/ oral anticoagulants eg, warfarin/coumarin-type & novel oral anticoagulants (eg, apixaban, dabigatran & rivaroxaban). Concomitant use w/ aspirin. Closely monitor renal function in patients w/ severe renal impairment (CrCl <30 mL/min) or those who may be predisposed to fluid retention & initiate treatment at lowest recommended dose; in patients w/ advanced renal disease. Initiate at lowest recommended dose in moderate hepatic impairment (Child-Pugh class B). Not recommended in severe hepatic impairment (Child-Pugh class C).
