Is It Risky To Have Thick Heart

nitrofurantoin mcr 100

My mother is taking Nitrofurantoin-mcr 100 for a UTI infection. In the past she has been on other antibiotics for the same and the infection has come back within days of use. Now she has been using the nitro- for 3 days, she has noticed that now it seems she has a bit of thickened blood in her urine. She is also taking a blood thinner(cumadin) for a heart problem. Is this a possible side effect of the med. ## Hello, Ken! How is your mother doing? On this, I'd suggest she see her doctor to have it checked out. It may just be from the UTI, but with her being on the Coumadin, any bleeding can be risky and isn't something to just wait around and see what happens. Do they know what's causing the repeated UTIs?
