As the elderly population continues to grow, many older adults live with multiple chronic illnesses and require long-term medication. Taking five or more medications at the same time, known as polypharmacy, is common among seniors. Besides increasing the risk of drug interactions and side effects, it may raise the likelihood of falls by 1.5 to 3 times.

Pharmacist Jiang Yan-Lin from Taipei City Hospital Zhongxiao Branch said polypharmacy is often seen in patients with hypertension, diabetes, and cardiovascular diseases. As the number of medications increases, interactions between drugs or health supplements may affect treatment outcomes and cause side effects such as dizziness and drowsiness.

Some blood pressure medicines, sedatives, and pain relievers may affect balance and reaction ability, increasing the risk of falls and fractures. Long-term use of multiple medications may also place extra strain on the liver and kidneys. Patients who visit different hospitals or departments without providing complete medication information may receive duplicate prescriptions.

To reduce these risks, patients should inform healthcare providers about all prescription medications, traditional Chinese medicines, and health supplements they use. Medication records can be checked through Taiwan's National Health Insurance mobile app. People taking multiple long-term medications may also seek assistance from pharmacists for medication reviews.
