Understanding Medication Side Effects: Impact on Fall Risk in Older Adults
Fall Prevention: How Common Medications Influence Balance and Safety
Falls among the elderly are a major concern, and while obstacles or slippery floors often come to mind as primary culprits...
...there's another factor that's frequently overlooked:
The medications in your medicine cabinet
Many commonly prescribed drugs can influence balance and mental clarity...
...turning them into potential risks for falls.
As we explore these medications and their side effects...
...it becomes imperative to highlight the
importance of regularly reviewing your medication list with your physician.
Understanding the risks versus benefits of certain drugs...
...can pave the way for safer choices and preventive measures.
1. Opioids for Pain Relief
What They Do:
These are powerful painkillers often prescribed after surgeries or for chronic pain conditions.
Potential Side Effects:
They can make you feel drowsy, dizzy, or even a bit confused
...thus increasing the chances of a fall.
2. Blood Pressure and Heart Medications
Antihypertensives, Antiarrhythmics
What They Do:
Keep your heart ticking rhythmically and prevent your blood pressure from shooting up.
Potential Side Effects: They might make you feel lightheaded,
...especially when you stand up suddenly.
This happens because the medication is doing its job,
...but it can surprise you and lead to stumbles.
In my practice, I've encountered many patients
...who were on multiple blood pressure and heart medications,
...often combined with a diuretic (see below).
On one occasion, a patient kept falling almost daily
...and complained of frequent dizziness.
Upon reviewing her medications, it became evident
...she was taking higher doses of her blood pressure
...and heart rhythm medications than what was recently prescribed.
The doctor had adjusted her dosage a few months prior,
...but she, perhaps out of habit or oversight,
...continued with the older, higher doses.
Notably, she hadn’t been monitoring her blood pressure regularly.
When I checked, it was a concerning 90/50.
Once she adhered to the correct dosage, her dizziness subsided.
3. Diuretics (Water Pills)
What They Do: Diuretics are often referred to as "water pills."
They help remove excess fluid from the body...
...which is especially helpful for conditions like hypertension (high blood pressure) and certain heart conditions.
By helping the body shed extra water and salt...
...they reduce the volume of blood the heart has to handle...
...making it easier for the heart to pump and reducing blood pressure.
Potential Side Effects:
Diuretics can lead to dehydration if the body loses too much fluid.
This, in turn, can cause dizziness or lightheadedness, especially when standing up quickly.
Moreover, diuretics can affect the balance of electrolytes, the essential minerals in our body...
...that help regulate fluid balance, muscle contractions, and nerve signals.
An imbalance can disrupt these crucial functions.
...which can result in symptoms like weakness, muscle cramps...
...and heart palpitations—all of which can increase the risk of falls.
4. Anti-Anginal Medications
What They Do:
Anti-anginal medications are designed to alleviate chest pain (angina)
...caused by reduced blood flow to the heart muscle.
They function by widening the blood vessels,
...which enhances oxygen delivery to the heart muscle
...and can help decrease the heart's workload.
Potential Side Effects:
These drugs can cause a drop in blood pressure,
...leading to dizziness or lightheadedness.
This sudden drop, especially when moving from a lying or sitting position to standing,
...can increase the risk of falls.
5. Anti-Anxiety Medications
The drugs in the table above belong to the group called benzodiazepines.
There is another medication Buspirone (Buspar®) which is not a benzodiazepine but used for treating anxiety.
What They Do: These medications are prescribed to reduce anxiety and promote relaxation.
Some are also used as muscle relaxants or to treat seizures.
Potential Side Effects:
Many anti-anxiety medications can make the person feel drowsy or fatigued.
Dizziness is a common side effect of these drugs.
It can get worse when standing up quickly or changing positions.
Some people might experience muscle weakness or lack of coordination
These medications can affect thinking, judgment, and memory, increasing the risk of falls.
Long-term use of benzodiazepines can lead to physical dependence.
It's important to note that side effects of benzodiazepines, especially drowsiness and dizziness,
combined with impaired cognitive function,
can significantly increase the risk of falls.
6. Antidepressants
What They Do: These medications are primarily prescribed to treat depression.
They work by altering the levels of certain chemicals in the brain...
...such as serotonin...
...which is supposed to help regulate mood.
Potential Side Effects:
Anti-depressants can cause dizziness...
...especially when standing up quickly...
...which can be due to a drop in blood pressure (orthostatic hypotension).
Some antidepressants can have a sedative effect (drowsiness).
These medications have been shown to cause confusion,
...especially in older adults or at higher dosages.
Among other side effects are...
...blurred vision, dry mouth, dehydration, urinary retention...
...and reduced alertness and reaction time.
When using antidepressants, patients need to have regular check-ins with their healthcare providers to adjust dosages or medication types if needed.
7. Anti-Diabetic Medications
What They Do:
These medications are used to manage and control blood sugar levels in individuals with diabetes.
They work in various ways, such as increasing insulin secretion,
...decreasing sugar production in the liver,
...or improving insulin sensitivity.
Potential Side Effects Related to Falls:
Hypoglycemia (Low Blood Sugar):
Some anti-diabetic drugs, especially insulin, can cause blood sugar levels to drop too low,
...leading to hypoglycemia.
Symptoms of hypoglycemia include dizziness, lightheadedness,
...shakiness, sweating, confusion, and fainting.
These symptoms increase the risk of falls.
It's essential for individuals to monitor their blood sugar regularly
...and recognize the signs of hypoglycemia.
Dizziness and Fatigue. Apart from hypoglycemia, some anti-diabetic medications
...can lead to dizziness and fatigue as side effects,
...both of which can contribute to an increased fall risk.
8. Anti-psychotics
What They Do:
Antipsychotic medications are prescribed to manage and treat symptoms of psychotic disorders,
...such as schizophrenia or bipolar disorder,
...and can also be used for symptoms like hallucinations and delusions.
Some are also prescribed off-label for issues like insomnia or agitation in dementia.
Potential Side Effects:
These drugs can lead to blurred vision, dizziness, and sedation,
...all of which can increase the risk of falls.
Additionally, they can cause tremors, stiffness, and restlessness,
...potentially affecting balance and walking.
Orthostatic hypotension, a sudden drop in blood pressure when standing up,
...can also be a side effect, leading to dizziness and increased fall risk.
9. Antihistamines
What They Do:
Antihistamines are primarily used to treat symptoms of allergies...
...such as sneezing, runny nose, itchy or watery eyes, and itching of the nose or throat.
They can also be found in many over-the-counter sleep aids...
...and medications for the common cold.
Potential Side Effects:
Drowsiness is a well-known side effect of many antihistamines,
...especially the older ones like Diphenhydramine (Benadryl®).
This drowsiness can lead to reduced alertness and slower reaction times,
...both of which can increase fall risk.
Other side effects include dizziness, blurred vision, dry mouth, constipation, and urinary retention.
10. Anticholinergics
Anticholinergic Drugs:
Our bodies use a messenger called acetylcholine for various functions
...like muscle movement and regulating heart rate.
Anticholinergic drugs block this messenger's actions.
Think of it like a key and lock:
...acetylcholine is the key, and the drug blocks the keyhole, preventing certain body functions.
What They Do:
Anticholinergic drugs block the action of acetylcholine, a neurotransmitter in the brain.
They are used to treat a variety of conditions including allergies, overactive bladder,
...gastrointestinal cramps, and some symptoms of Parkinson's disease.
Additionally, some are used as sleep aids or to treat depression.
Potential Side Effects:
These medications can cause dizziness, drowsiness, blurred vision, and confusion,
...especially in older adults.
The combination of these side effects can make a person more prone to stumbling
...or not recognizing environmental hazards, increasing the risk of falls.
NOTE:
While Diphenhydramine (Benadryl®) is commonly known as an antihistamine,
...it also has strong anticholinergic properties, which is why it's included in both categories.
Amitriptyline (Elavil®) is primarily categorized as a tricyclic antidepressant (TCA).
However, many TCAs, including Amitriptyline, have notable anticholinergic effects.
This is why some antidepressants, especially the older ones like TCAs,
...can produce side effects associated with anticholinergic activity.
11. Anti-seizure Medications
What They Do:
These medications are primarily prescribed to control seizures in conditions like epilepsy.
However, some of them are also used to treat bipolar disorder,
...neuropathic pain, and migraines.
Potential Side Effects:
Dizziness and Coordination Issues:
Many anticonvulsants can cause dizziness or a feeling of unsteadiness.
This is particularly concerning for older adults as it directly increases the risk of falls.
Drowsiness:
Feeling overly sleepy or fatigued can affect one's ability to focus and navigate safely.
Visual Disturbances:
Some anti-seizure medications can affect vision,
...leading to double vision or blurred vision,
...making it difficult to perceive the environment correctly.
Cognitive Impairments:
In some cases, these medications can lead to confusion or slowed thinking.
12. Sleeping Aides
1. Prescription Sleep Aids
What They Do:
These medications are specifically designed to help people fall asleep faster,
...stay asleep longer, or both.
They act on the brain to produce a sedative effect.
Potential Side Effects:
Drowsiness:
This is the intended effect, but if the drowsiness carries over to the next day,
...it can impair coordination and increase fall risk.
Dizziness:
This can impair balance and increase the likelihood of trips or falls.
Complex Sleep Behaviors:
Rarely, people can perform activities like walking, eating,
...or even driving while not fully awake.
This increases the risk of falls and injuries.
2. Over-the-counter (OTC) Sleep Aids
What They Do:
These are accessible without a prescription and are used
...to relieve occasional sleeplessness.
They either have a sedative effect or adjust the internal body clock.
Potential Side Effects:
Drowsiness: Just like prescription aids, the drowsiness can spill over to the next day.
Dizziness: Especially common in older adults, it can increase the risk of falls.
Blurred Vision or Dry Mouth (for antihistamines like Diphenhydramine and Doxylamine): These can be disorienting and increase fall risk.
Confusion: Especially in older adults, this can further contribute to unsteadiness.
As with all other medications discussed in this article, it's crucial to avoid alcohol when taking sleeping aids, as it can intensify side effects.
13. Muscle Relaxers
What They Do:
Muscle relaxants are typically prescribed to relieve muscle spasms, pain, or muscle tightness.
They work by either decreasing muscle tone or affecting the nervous system directly.
Potential Side Effects:
Drowsiness:
One of the most common side effects, which can result in impaired coordination
...and an increased risk of falls.
Dizziness or Lightheadedness:
These can make it more challenging to maintain balance,
...especially when standing up quickly.
Weakness:
This can affect stability.
Confusion:
Especially in older adults, this can increase the risk of accidents and falls.
Blurred Vision:
This sensory disruption can make it difficult to navigate surroundings safely.
14. Anti-Coagulants (Blood Thinners)
What They Do:
Anticoagulants, or blood thinners, are medications used to reduce the risk of blood clots,
...which can lead to strokes, heart attacks, and other serious conditions.
They are often prescribed for people with certain heart or blood vessel conditions
...and for those who have had certain procedures or surgeries.
Potential Side Effects:
Bleeding:
The primary risk of anticoagulants is bleeding.
While this isn't a direct cause of falls if an older adult on anticoagulant falls
...and injures themselves, the risk of severe bleeding is heightened.
Even minor injuries can become serious if excessive bleeding occurs.
Dizziness or Weakness:
Some patients may experience these symptoms, increasing the risk of falls.
Bruising:
A person on blood thinning medication might bruise more easily, which isn't a fall risk per se,
...but it's worth noting as a sign of potential excessive bleeding from a minor trauma.
A Proactive Approach to Safety for Older Adults
As we age, medications may help us in managing various health conditions
...and maintaining our quality of life.
But, as highlighted in this article, many of these drugs carry side effects
...that can inadvertently increase the risk of falls.
This is especially significant for older adults,
...who might already have other factors heightening their vulnerability.
For older adults, their children, and caregivers, it's crucial to be aware of these potential risks.
Regularly reviewing medications, being informed about their side effects,
...and understanding their interactions
...can pave the way for safer and more effective drug usage.
While healthcare professionals offer guidance,
...the responsibility is also on individuals and families to stay proactive.
By asking questions, maintaining open communication,
...and even seeking second opinions when unsure,
...older adults can find the balance between benefiting from medications and staying safe.
