I am 24 years old and I was recently put on Fiorinal Cap Novartis for extremely bad headaches. I never had headaches like this before and I am assuming that because of the intense pain I passed out. I had a seizure-like episode and that is when I decided to go to my physician. Since I have been on the medication my headache has not gone away. I did notice however, that my stool color has changed to a dark brown to black color and a few spots of blood are occassionally observed after cleansing. In addition to the change in stool color, I also noted bruising in numerous areas of my body for no particular reason. Is this a result of the medication? Should I go back to my physician and inform him of these changes?
