As we get closer to middle age, the number of medications we take increases. This trend raises serious questions about medication safety, necessity, and financial costs. According to recent studies, polypharmacy—taking five or more medications daily—is no longer just a problem for the elderly. By the age of 40, one in four adults meets the criteria for polypharmacy.
Polypharmacy carries serious risks, including: dosage errors, dangerous drug interactions, increased risk of falls, cognitive problems, and even hospitalization. The problem is not only in the number of pills but in how these medications interact with each other, which can worsen a person’s health condition.
This problem is particularly relevant for middle-aged people, as they have to manage chronic diseases such as diabetes, hypertension, and others. Experts fear that uncontrolled medication intake may prove to be more harmful than beneficial.
According to a study published in the Journal of General Internal Medicine, taking five or more medications in middle age is associated with a decline in physical functions. Although it is unknown whether the medications directly cause the weakness or if weak people simply need more medication, the connection between these two phenomena is strong and alarming.
Dr. Caroline Sloane, an assistant professor at Duke University, notes: “There is always a risk when taking multiple medications, as they can interact with each other and cause side effects.” For example, using several diabetes drugs at the same time may dangerously lower blood sugar levels, while the combination of anticoagulants and antiplatelet agents increases the risk of bleeding.
Geriatrician Alison M. Macy notes that older patients are particularly vulnerable because metabolism and tolerance change with age, which can make a dose of medication that was safe in youth potentially harmful.
Managing many medications is difficult. Pharmacist Dana Carroll explains that the more medications a patient takes, the more specialists are involved in their treatment, which increases the risk of communication gaps and errors. While computer systems help doctors detect drug interactions, their effectiveness is only achieved with regular use.
For patients, a complex medication regimen is often confusing and exhausting, which reduces the motivation to adhere to the treatment regimen. This can lead to inadequate control of the disease and unexpected hospitalization.
What Can Be Done?
Experts emphasize the need to regularly review the list of medications. Michelle Keller, from the University of Southern California, notes that checking medications helps to rule out unnecessary or inappropriate drugs. In this process, it is also important to consider supplements and vitamins, as they can affect the effectiveness of the prescribed medications. For example, St. John’s Wort or Ginkgo biloba can interact with blood thinners or antidepressants.
The interaction with alcohol further complicates medication safety, especially in the case of drugs that cause drowsiness and increase the risk of falls and injuries.
De-prescribing: A Path to Safe Treatment
De-prescribing does not only mean reducing the number of pills but also consulting with patients and their families. Keller notes that some medications, such as benzodiazepines, which are prescribed for short-term anxiety and sleep problems, are often taken for too long, which causes their risks to outweigh their benefits. In contrast, switching to cognitive-behavioral therapy (CBT) may be a safe, long-term alternative for insomnia.
Stopping antidepressants should be done by carefully tapering the dose to avoid withdrawal symptoms, such as mood changes and insomnia. Antidepressants like SSRIs are generally safe, but monitoring is still necessary.
However, it is also important to remember that not all medications are superfluous. For chronic diseases, such as hypertension and diabetes, taking certain drugs is essential. The goal is optimized therapy, where the patient only takes the necessary medications and reduces the number of unnecessary or harmful ones. Keller warns: “Medications that were intended for short-term use should not remain in the prescription for years.”
Polypharmacy requires a team approach—cooperation between primary care doctors, specialists, pharmacists, and patients. Although electronic healthcare tools are developing, human communication is still fundamental.
Patients should have the opportunity to ask questions about the purpose and necessity of each medication. The simpler the treatment regimen, the greater the chance that the patient will adhere to it, which will ultimately improve their quality of life.
