As we age, it’s common to see an increase in the number of medications we take. This often leads to polypharmacy, a term used to describe the use of multiple medications by a single patient. Polypharmacy is particularly prevalent among older adults, who are more likely to develop chronic illnesses that require ongoing treatment. But with the growing number of medications comes an increase in potential risks and complications.
Polypharmacy is typically defined as the use of five or more medications, though different definitions may set the threshold at four, ten, or even fifteen drugs. The phenomenon is widespread among older adults; in 2021, a quarter of Canadians over 65 were prescribed more than ten different classes of medication. In Québec, the average number of drugs used by persons over 65 was 8.7 in 2016. These figures highlight the prevalence of polypharmacy and the need for careful management.
While medications are essential for managing many health conditions, the simultaneous use of multiple drugs can lead to significant challenges. Research shows that seniors and their caregivers are generally open to reducing the number of medications if advised by their doctors. Despite satisfaction with their treatments and trust in their healthcare providers, many are willing to explore de-prescribing to enhance overall well-being.
However, managing polypharmacy effectively requires balancing the benefits and risks. Here are five key points to consider:
Drug Interactions: The more medications a person takes, the higher the risk of interactions that can cause adverse effects or diminish the effectiveness of treatments.
Conflicting Effects: A drug beneficial for one condition might exacerbate another, complicating treatment for patients with multiple illnesses.
Increased Adverse Effects: Older adults taking multiple medications face higher risks of side effects, such as confusion or falls, which can lead to severe consequences.
Potentially Inappropriate Medications: Some drugs may pose more risks than benefits for seniors. For instance, benzodiazepines, commonly used for anxiety or sleep, are associated with increased risks of confusion, falls, and dependence.
Health Complications: Polypharmacy is linked to adverse health outcomes like frailty, hospital admissions, and emergency room visits. The specific impact of polypharmacy is complex, as it often coexists with multiple illnesses that also contribute to these risks.
Given these challenges, what can patients and caregivers do to mitigate the risks associated with polypharmacy?
Ask Questions: Whenever a new medication is prescribed, inquire about its benefits, potential side effects, compatibility with other treatments, and duration of use. Understanding the purpose and implications of each drug is crucial.
Review Medications Regularly: Ensure that all medications are still necessary and beneficial. Regular reviews with healthcare providers can help identify any drugs that may no longer be needed or might be causing adverse effects.
Consider De-prescribing: De-prescribing involves reducing or stopping medications that are no longer appropriate. This practice requires a collaborative approach, involving patients, their families, and healthcare professionals. The Canadian Medication Appropriateness and Deprescribing Network provides valuable resources for this process.
The ultimate goal is to ensure that every medication taken provides more benefits than risks. While it’s common for older adults to require multiple medications, this shouldn’t be accepted without scrutiny. Regular reviews, informed questioning, and the consideration of de-prescribing can help manage polypharmacy effectively.
In conclusion, as we navigate the complexities of polypharmacy, the principle of “everything in moderation” often applies. Medications play a vital role in maintaining health, but careful management is essential to avoid the pitfalls of taking too many drugs. By staying informed and proactive, patients and caregivers can work with healthcare providers to optimize medication use, enhancing health and quality of life.
