Interactions
Ketoprofen is known to interact with other drugs, the details of drug interactions is as follows:DrugDetailsSeverityOnsetManagementCyclosporin AFrusemide or FurosemideKetoprofen may diminish the diuretic effect of Furosemide.ModerateMonitor for decreased therapeutic effects of Furosemide if a nonsteroidal anti-inflammatory agent (NSAID) is initiated/dose increased, or increased effects if an NSAID is discontinued/dose decreased. Consider using an NSAID that holds a lesser potential for interacting with Furosemide (eg, diflunisal, flurbiprofen, ketoprofen, and ketorolac). Patients with heart failure may be more sensitive to alterations in fluid balance, in which case consideration should be given to avoiding the concomitant use of NSAIDs and Furosemide. Cirrhotic patients with ascites may also be at increased risk.LithiumMethotrexateExcretion of methotrexate is reduced by ketoprofen thus increase toxicity.MajorLow dose of methotrexate should be used and closely monitor thesign and symptoms of bone marrow suppression and nephrotoxicity.Probenecid These interactions are sometimes beneficial and sometimes may pose threats to life. Always consult your physician for the change of dose regimen or an alternative drug of choice that may strictly be required.
