Drug Interactions
Increased risk of gastrointestinal ulceration or bleeding with antiplatelet agents, SSRIs, corticosteroids. May exacerbate cardiac failure, decrease GFR, and increase plasma levels of cardiac glycosides. Increased risk of nephrotoxicity with ciclosporin and tacrolimus. May interfere with the natriuretic effects of diuretics. May increase plasma levels of lithium. May antagonise the hypotensive effects of antihypertensive agents. May decrease excretion of methotrexate, leading to acute toxicity. May increase risk of convulsion with quinolones. May interfere with mifepristone mediated termination of pregnancy.
