Your body goes through many changes after an SCI. This includes how your body absorbs medicine. If you used a medicine, herb, or vitamin before your injury, it may work differently now. And you may be at higher risk for side effects and interactions between medicines than before. So be sure all of your health care providers know about all the medicines you take. This includes things you buy over the counter as well as prescription medicines. It also includes herbs, vitamins, and other supplements. This will help keep you safe and healthy.
