Lots of meds can contribute to easy bruising. Especially blood thinning drugs or any drug which effects blood platelets. Aspirin, Coumadin, Vitamin E, Ginkgo Biloba etc.. have a tendency to thin the blood. Also mixing certain vitamins and herbs with medications can increase bruising (and bleeding). As can Alcohol, such as wine, whisky, brandy etc. It's possible that certain HBP medications such as TOPROL, COREG, BYSTOLIC also share some of these blood thinning properties. This is a question you should also ask your doctor.
