NB In any case do more frequent INR with any additional medication.

Cefuroxime may increase the effects of warfarin and cause you to bleed more easily. You may need more frequent monitoring of your INR after starting cefuroxime or whenever it is discontinued, and appropriate adjustments made in your blood thinner dosage if necessary.

THE BOTTOM LINE When prescribing antibiotics for patients taking warfarin, try to choose agents with a lower likelihood of affecting INR such as penicillin G, clindamycin, and 1st- and 4th-generation cephalosporins.

First and fourth generation cephalsporins.
