                                Oseltamivir + Warfarin
                            
                        

                        
                        
Oseltamivir does not appear to meaningfully alter warfarin pharmacokinetics; however, the febrile illness being treated may independently elevate INR, which can be mistakenly attributed to the antiviral.

                                Oseltamivir + Methotrexate
                            
                        

                        
                        
Both oseltamivir carboxylate and methotrexate rely on renal tubular secretion via OAT transporters; theoretically, competition could reduce elimination of either drug, though clinical evidence of a significant interaction is limited.
