Polypharmacy

Modern medicine provides us with many life-saving prescription drugs. Medications support greater health for many. However, people taking five or more medications are at risk for polypharmacy. 
Kathleen Woodruff of the Johns Hopkins School of Nursing explains the prevalence of polypharmacy with these statistics:
"Currently, 44% of men and 57% of women older than age 65 take five or more medications per week; about 12% of both men and women take 10 or more medications per week. These agents include both prescription and over-the-counter (OTC) preparations, such as vitamin and mineral supplements and herbal products."
Older adults are at a higher risk for polypharmacy for the following reasons:

• As a group, they take more medications than younger people. 
• Some have problems with vision, hearing, cognition, and fine motor skills that make adherence a challenge.
• They are likely to be seeing specialists, who may not be coordinating all prescriptions. 
• Their aging bodies metabolize medicines differently.  

Part of polypharmacy includes pill burden. "Pill Burden" is a term for difficulty managing multiple medications.  This can be confusing to sort out: "When do I take this pill?" "How many do I take?" "Do I take this with or without food?"  "Do two of my pills look very similar to each other?"  "Is this my prescription bottle or my spouse's?"  
Polypharmacy leaves people at risk for side effects and for bill burden.  Also, there is a domino effect. People taking medications often suffer side effects, which leads them to take another medication to manage that side effect. This can lead to non-adherence and to even more side effects.
If an older adult in your life is experiencing a new symptom, consider discussing the possibility of polypharmacy with his or her physician. Even medications taken over a long period of time can produce new, unwanted side effects as the body ages.  My own step-father suffered internal bleeding that required hospitalization in the intensive care unit.  The offending medication?  Baby aspirin taken over a period of several years.
Brenda Jordan--advanced practice registered nurse and speaker in the podcast below--asks patience and health care providers to first consider drug side effects as the cause for new health complaints.
If you or your parent is taking multiple medications, consider the problem of polypharmacy so that you, our doctor and your pharmacist can manage this potential problem.
