I agree, but ask your doctor. I'll tell you, however, clean the area very well before using it.
I looked it up and it's a topical spray with an antimicrobial ingredient (benzethonium chloride) and a pain reliever (lidocaine). I don't see anything that would interfere with actual clotting mechanism in the body as a whole. The best thing to do is ask your doctor or pharmacist before using this.
