Have you ever stopped to look at your medicine cabinet and wonder if every single pill is truly helping you? Here’s a staggering fact: over half of all people over the age of 65 are taking five or more prescription medications. While many of these drugs are life-saving, this trend of “polypharmacy” has a dark side. As we get older, our bodies change, and medications that were once beneficial can start to cause more problems than they solve. I see this every single day in my practice—patients coming in with new issues that are actually side effects of their prescriptions.
My goal here isn’t to scare you or to tell you to throw your medications away. Absolutely not. This article is about empowerment. It’s about giving you the knowledge to have more informed conversations with your doctor. I want to walk you through five categories of common medications that I frequently see causing issues, particularly in an older population. By understanding the potential pitfalls, you can become a better advocate for your own health, ensuring your treatment plan is truly working for you, not against you. Remember, always speak to your doctor before starting, stopping, or changing any medication. (Based on the insights of Dr. Suneel Dhand)
Key Takeaways
- Question Your Prescriptions: As you age, your body’s reaction to medication can change. It’s crucial to regularly review your prescriptions with your doctor.
- Blood Pressure Pills Aren’t All Equal: Certain diuretics like hydrochlorothiazide can lead to dangerous electrolyte imbalances, dehydration, and dizziness.
- Anxiety Meds Can Increase Fall Risk: Benzodiazepines, often used for sleep and anxiety, can cause over-sedation and drowsiness, leading to dangerous falls.
- Nerve Pain Drugs May Cause Brain Fog: Medications like gabapentin can be highly sedating, and this effect can often be mistaken for signs of aging.
- Pain Relievers Can Harm Internally: High-dose NSAIDs (like ibuprofen) can damage your kidneys and lead to serious stomach bleeding over time.
- Blood Thinners Require Vigilance: Anticoagulants are vital for preventing clots but carry a constant risk of bleeding that you must monitor carefully.
1. Hydrochlorothiazide: The “Water Pill” with Hidden Dangers
Hydrochlorothiazide, often abbreviated as HCTZ, is one of the most common medications prescribed for high blood pressure. It’s a type of diuretic, or “water pill,” meaning it works by helping your kidneys flush excess water and salt from your body. While it can be effective at lowering blood pressure, I can’t tell you how many times I’ve seen it cause significant problems, especially for anyone over 65.
The main issue is that HCTZ doesn’t just remove water; it also flushes out essential electrolytes, most notably potassium. When your potassium levels drop too low—a condition called hypokalemia—you can experience muscle weakness, cramps, fatigue, and even heart palpitations. Furthermore, the diuretic effect can easily lead to dehydration. This becomes especially dangerous if you get sick with something that causes vomiting or diarrhea. Your blood pressure can suddenly drop too low, making you feel dizzy, lightheaded, and dramatically increasing your risk of a fall. If you’re on this medication, it’s vital to be aware of these risks and discuss any symptoms of dizziness or weakness with your doctor. There are many other classes of blood pressure medications that may be a safer alternative for you.
2. Benzodiazepines: The Double-Edged Sword for Anxiety and Sleep
This category includes some very well-known drugs: diazepam (Valium), lorazepam (Ativan), and alprazolam (Xanax). These medications, known as benzodiazepines, are typically prescribed to manage anxiety, panic attacks, or to help with sleep. While they can feel effective in the short term, they come with a heavy price, particularly as you get older.
The most common problem I see is over-sedation. As you age, your liver and kidneys don’t clear medications as efficiently as they used to. This means a dose that was perfect for you ten years ago might be far too strong for you today, leaving you feeling completely “zonked out.” This isn’t just about feeling tired; it’s a profound drowsiness that impairs your judgment, coordination, and reaction time. A very common and tragic scenario I see in the hospital is an older person, who is on a benzodiazepine, gets a minor illness like a UTI or a cold. The combination of the illness and the medication makes them excessively drowsy, they get out of bed, and they fall—often resulting in a hip fracture or a head injury. If you’re taking one of these medications, it’s crucial to ask yourself and your doctor if the benefit is still worth this significant risk.
3. Gabapentin: More Than Just Nerve Pain Relief
Gabapentin (brand name Neurontin) is widely prescribed for nerve-related pain, such as diabetic neuropathy or shingles pain. However, its most significant and often underestimated side effect is sedation. I am frequently shocked to see older patients, sometimes in their 80s or 90s, on whopping doses of gabapentin—hundreds of milligrams taken multiple times a day.
The sedative effect can be so profound that it completely changes a person’s personality and alertness. A loved one might think their family member is just slowing down due to age, when in reality, they are heavily medicated. I’ve had experiences in the hospital where we’ve had to stop a patient’s gabapentin because they were too drowsy. A few days later, their family will visit and say, “Wow, we haven’t seen them this awake and engaged in years.” It’s a powerful reminder that this medication can essentially put a chemical blanket over a person’s consciousness. While gabapentin certainly has a place and can be a lifesaver for those with debilitating nerve pain, the dose is critical. If you or a loved one is on this medication and experiencing constant fatigue or brain fog, it is absolutely worth discussing with your doctor whether the dose is too high or if another option might be better.
4. High-Dose NSAIDs: The Over-the-Counter Threat to Your Insides
Non-steroidal anti-inflammatory drugs, or NSAIDs, are among the most common pain relievers in the world. This category includes over-the-counter medications like ibuprofen and naproxen, as well as prescription-strength versions like diclofenac. Many people take them for chronic conditions like arthritis, often at high doses like 600mg or 800mg several times a day. While they can be great for pain, this long-term, high-dose use can be incredibly destructive.
I see two major problems. First is kidney damage. NSAIDs can reduce blood flow to the kidneys, and over months or years, this can permanently impair their function. It’s not uncommon for an older patient to be admitted to the hospital with failing kidneys, and upon reviewing their history, we discover they’ve been taking high-dose ibuprofen for years. The second, and even more common, issue is gastrointestinal (GI) bleeding. These drugs are harsh on the stomach lining and can cause ulcers. A patient might come to the hospital feeling weak and dizzy, and we find their hemoglobin is dangerously low. They’ve been having a slow, silent bleed from a stomach ulcer caused by their anti-inflammatory medication. Signs of a GI bleed can include black, tarry stools or feeling unusually tired and pale. If you need to be on a high-dose NSAID, you must discuss strategies to protect your stomach and monitor your kidney function with your doctor.
5. Anticoagulants: The Fine Line of Blood Thinning
Anticoagulants, or blood thinners, are essential medications for people who have atrial fibrillation or a history of blood clots. For decades, warfarin was the standard, requiring frequent blood tests to ensure the dose was right. Now, newer drugs like apixaban (Eliquis) and rivaroxaban (Xarelto) are much more common because they don’t require that constant monitoring. However, this convenience can lead to a false sense of security.
The entire purpose of these medications is to prevent your blood from clotting, which means their primary side effect is bleeding. This risk is always present. A fall can become much more dangerous, and internal bleeding is a constant concern. You could develop a stomach ulcer (perhaps from also taking NSAIDs) and bleed excessively, or you could just have a slow, chronic bleed that goes unnoticed. This can cause your hemoglobin to slowly creep down, leading to progressive anemia, fatigue, and weakness. If you are on any blood thinner, you must be incredibly vigilant. Watch for signs like excessive bruising, nosebleeds that won’t stop, or blood in your urine or stool. It’s a wise idea to have your doctor check your blood count a few weeks after starting the medication and periodically thereafter to ensure you’re not developing a slow, silent bleed.
Conclusion: Become Your Own Health Advocate
To recap, we’ve looked at hydrochlorothiazide, benzodiazepines, gabapentin, high-dose NSAIDs, and anticoagulants. These are all powerful and useful medications, but they carry serious risks that increase as you age. The real problem in modern medicine is often not a single drug, but the accumulation of many. It’s a phenomenon I call the “prescribing cascade,” where you are given a second drug to treat the side effects of the first, then a third to treat the side effects of the second, and so on. I’ve seen patients with medication lists 20 or 30 drugs long, and it’s often impossible to tell what’s causing what.
My final message to you is this: you are the most important member of your healthcare team. Take an active role. Keep an updated list of your medications and review it with your doctor at every visit. Ask questions. Is this medication still necessary? Is this dose still right for me? Could any of my symptoms be a side effect? Don’t be afraid to push for de-escalation—to see if you can safely reduce or eliminate prescriptions. By staying informed and engaged, you can help ensure your medications are truly serving your health and well-being.
