Hi all! I'm sure this has been said many a time on here, but we are our own best advocates! It surprises me how many medical professionals don't know about interactions with warfarin. I recently went to a dermatologist and they wanted to prescribe a couple different antibiotics to clear up some skin issues. I asked if there were interactions with warfarin and she said "oh no, why would there be an interaction?" I asked her to just check and she did, and of course what she wanted to give me can cause a pretty big increase in INR. So long story short, I'm glad I had given myself enough education on the topic to know to ask!
