Medications acting on the brain (also known as centrally acting medication) can increase your risk of falls due to their adverse effect on brain function, resulting in drowsiness, slower reaction times and impaired balance. Some cardiovascular medications (medications to treat heart, circulation and blood pressure problems) can increase your risk of falls too, but others have been shown to decrease your falls risk. Some medicines can make you dizzy or lightheaded, which can predispose you to falling over. You should never stop or change your medications without talking to your doctor.
