The following drugs are responsible for seven in 10 emergency hospitalizations among adults 65 and older, according to the Centers for Disease Control and Prevention:
1. Warfarin (Coumadin, Jantoven)
3. Oral antiplatelet agents, such as aspirin or clopidogrel (Plavix)
4. Oral hypoglycemic drugs for diabetes
These can be life-saving medications, but they do require extra monitoring by doctors and patients to prevent side effects and interactions. Warfarin accounts for one-third of the emergency visits.
