Introduction

This article, part of a three-part series focusing on seniors and driving, sheds light on a critical yet often overlooked concern— the potential impact of over-the-counter medications on senior drivers. While these medications might seem harmless and easily accessible, their effects on older adults, particularly regarding driving safety, warrant closer attention.

Age-Related Changes in Medication Processing

Jeannie Lee, an esteemed associate professor at the University of Arizona’s College of Pharmacy, highlights the significance of understanding how aging affects the body’s processing of medications. As individuals age, physiological changes occur, affecting kidney and liver function. These alterations impact the elimination of drugs from the body, potentially leading to drug accumulation and toxicity.

Medication Dosage and Driving Safety

Lee stresses the importance of considering lower medication doses for older adults to mitigate the risk of prolonged drug presence in the body. Despite reduced doses, the therapeutic benefits remain effective.

Medications and Driving Safety

Certain medications, even those available over-the-counter, can subtly impair driving ability. Lee emphasizes that impaired vision, confusion, dizziness, headaches, and light-headedness are common side effects that could compromise a senior’s driving capability.

Recommendations and Tools for Safer Medication Use

To ensure safe driving, it’s crucial for seniors to consult healthcare providers or pharmacists before taking any medication. The Beers Criteria, an annually updated list by the American Geriatrics Society, assists in identifying potentially inappropriate medications for individuals aged 65 and above.

Tips for Safe Medication Use Among Seniors

• Comprehensive Medication List: Seniors should maintain a detailed list of prescribed drugs, over-the-counter medications, vitamins, and herbal remedies, and discuss these with healthcare professionals.
• Understanding Medications: It’s vital to comprehend the purpose, potential interactions, side effects, and available alternatives for each medication.
• Avoiding Duplicate Medications: Lee strongly advises against consuming two medications containing the same active ingredients simultaneously.
• Exploring Alternative Solutions: Before opting for over-the-counter medications, exploring alternative remedies such as rest, therapy, or holistic approaches is recommended.

Specific Medications of Concern

Lee highlights several categories of medications that warrant caution among seniors due to their potential adverse effects on driving and overall well-being:

• Antihistamines: Drugs like Benadryl or cold medicines containing antihistamines can cause various issues including confusion, dizziness, and dryness.
• Sleeping Aids and Anxiety Medications: These drugs, often containing benzodiazepines, can lead to cognitive impairment, potentially causing unusual sleep-related behaviors.
• Blood Pressure, Antidepressants, and Pain Medications: These medications may induce drowsiness, dizziness, confusion, and sedation.
• Atypical Antipsychotics: Prescribed for dementia-related symptoms, these medications can cause cognitive problems and tremors.

Exploring Safer Alternatives

For those seeking safer options, Lee suggests considering alternatives like Melatonin, a hormone aiding sleep regulation, rather than opting for potentially problematic over-the-counter sleep aids.

Conclusion

Understanding the potential risks associated with over-the-counter medications among seniors is crucial for preserving driving safety and overall health. Implementing caution, seeking professional guidance, and exploring safer alternatives can significantly mitigate adverse effects, ensuring the well-being of the senior population.
