If you take a drug that makes you feel a little woozy, you should auto- matically adjust or limit your driving to stay safe. Problems can result when physiological changes of aging combine with drugs commonly prescribed for older adults. Those prescription drugs are the ones most likely to increase the risk of driving problems and accidents. Don’t ignore your body’s reactions when you’re on any medicines. If you feel drowsy, dizzy, nauseous, or headachy, you should not try to drive. .
