Interactions between your drugs
ketoprofen iodine I 131 tositumomab
Applies to: Nexcede (ketoprofen) and iodine i 131 tositumomab
MONITOR CLOSELY: Coadministration of tositumomab and iodine I 131 tositumomab with drugs that interfere with platelet function or coagulation may potentiate the risk of bleeding complications. Tositumomab and iodine I 131 tositumomab alone can cause severe or life-threatening thrombocytopenia. In premarketing clinical studies, NCI CTC grade 3 and 4 thrombocytopenia occurred in 53% of 230 patients, and sequelae included hemorrhage in 12% and requirement of platelet transfusions in 15% of patients. The time to thrombocyte nadir was 4 to 7 weeks and the duration of thrombocytopenia was approximately 30 days. However, 7% of the patients experienced thrombocytopenia that extended beyond 90 days following administration of the therapeutic regimen.
MANAGEMENT: Due to the frequent occurrence of severe and prolonged thrombocytopenia associated with tositumomab and iodine I 131 tositumomab, concomitant use of other medications that interfere with platelet function or coagulation should be considered cautiously. Close clinical and laboratory observation for bleeding complications is recommended during and after the therapeutic regimen. A complete blood count (CBC) with differential and platelet count should be obtained prior to and at least weekly for a minimum of 10 weeks after treatment.

Drug and food interactions
ketoprofen food
Applies to: Nexcede (ketoprofen)
GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.
MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.
