Falls represent the leading cause of injury and injury-related death among older adults in the United States, with more than one in four individuals over 65 reporting a fall annually. These incidents frequently lead to severe consequences, including hip fractures and traumatic brain injuries, significantly impacting quality of life and healthcare burdens.
Alarmingly, the number of fall-related deaths among those aged 65 and older in 2023 more than tripled compared to three decades prior. Researchers attribute this significant surge, in part, to the escalating use of certain prescription medications, which can profoundly exacerbate an older person’s inherent vulnerability to falls.
Older adults face an elevated fall risk due to various physiological changes, such as sensory impairment, gait and balance issues, and orthostatic hypotension – a sudden drop in blood pressure upon standing. Dr. Cara McDermott, an assistant professor of medicine in geriatrics at Duke University School of Medicine, highlights that aging itself diminishes the body’s natural ability to recover from a stumble, making the impact of perception-altering or balance-impairing drugs even more critical.
Several classes of medications are particularly implicated in increasing fall risk. Sedative-hypnotic drugs, commonly known as Z-drugs (e.g., zolpidem, eszopiclone) prescribed for insomnia, can induce dizziness, sedation, muscular weakness, and lack of muscle coordination. Similarly, benzodiazepines (e.g., alprazolam, lorazepam), used for anxiety and seizures, cause dose-dependent drowsiness, slowed reflexes, and impaired balance, effects magnified when combined with alcohol.
Antidepressants, including selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs), are also linked to higher fall incidence. SSRIs like escitalopram can cause orthostatic hypotension and dehydration, while both SSRIs and TCAs commonly lead to dizziness and sleepiness. Antipsychotic medications also contribute to fall risk through their sedative properties and effects on motor control, making concurrent alcohol use particularly hazardous.
Other critical drug categories include antihypertensives, which, especially when newly initiated, can lower blood pressure excessively and cause lightheadedness. Dopaminergic drugs, used for conditions such as Parkinson’s disease, may induce lightheadedness, reduced blood pressure, and involuntary movements. Anticonvulsants (e.g., gabapentin, pregabalin) for epilepsy and neuropathic pain exert significant central nervous system effects, resulting in dizziness, sedation, and ataxia, with higher doses presenting greater risks.
Opioids (e.g., oxycodone, hydrocodone) and muscle relaxants (e.g., cyclobenzaprine) are known to cause drowsiness, orthostatic hypotension, and cognitive impairment, significantly increasing fall susceptibility. Anticholinergic drugs, prescribed for various conditions from Parkinson’s to overactive bladder, can impair vision and muscle contraction, thereby hindering stable walking and elevating the risk of falls.
Mitigating medication-related fall risks necessitates proactive engagement between patients and healthcare providers. Experts, including Dr. John Batsis, a geriatrician at the University of North Carolina School of Medicine, emphasize the importance of openly discussing all medications with a doctor, regularly reviewing the necessity of each drug, and exploring potential dosage adjustments or safer alternatives.
Patients should remain vigilant for side effects such as dizziness or excessive sleepiness, which are clear indicators of increased fall risk. Dr. Katherine Ward, a geriatrician at Stanford Senior Care, strongly advises against combining prescription medications with recreational drugs or alcohol, warning that such untested interactions can lead to unpredictable and dangerous outcomes.
Further preventative measures include ensuring a safe home environment by maintaining clear, well-lit spaces. Individuals should also understand their personal fall risk before starting any new medication. Dr. McDermott stresses that medication decisions must be made collaboratively with a prescriber, taking into account personal preferences, co-existing health conditions, and any history of falls.
In conclusion, falls pose a serious and escalating health threat to older adults, with many commonly prescribed medications inadvertently exacerbating this danger through various side effects. Open communication with healthcare providers about medication lists, potential risks, and safer alternatives remains the cornerstone of safeguarding older adults from preventable fall-related injuries.
