When we talk about osteoporosis, we focus on bone density. That makes sense. But as I have written before on this blog, the fracture itself is what changes lives, and fractures almost always start with a fall. So anything that increases your chances of falling deserves serious attention.
One of the biggest and most modifiable fall risk factors is sitting right there on your kitchen counter: your medications.
Why This Matters More as We Get Older
Our bodies process medications differently as we age. The liver, which breaks down many drugs, gradually loses mass and blood flow over time. The kidneys, which clear medications from your system, decline in function in roughly two-thirds of older adults, reducing drug excretion by up to 50%. The result is that a medication you tolerated well at 50 may behave very differently in your body at 65 or 75. Drugs can linger longer, accumulate to higher levels, and produce side effects that were never a problem before.
This is not a flaw in the medication. It is a normal change in how your body handles it, and it means doses and drug choices may need to be revisited as you age.
The High-Risk Window: New Prescriptions and Dose Changes
One of the riskiest times for a fall is right after you start a new medication or have a dose increased. Your body has not yet adjusted, and side effects like dizziness, drowsiness, or drops in blood pressure are often most pronounced in those first days and weeks. The Mayo Clinic notes that fall risk increases after a new prescription and remains elevated with long-term use of certain drug classes.
If you have recently started something new or had a dosage change, pay extra attention to how you feel when you stand up, walk, or move through your home, especially at night.
The Medication Classes to Know About
Researchers have identified 14 classes of fall-risk-increasing drugs, sometimes called FRIDs. You do not need to memorize the list, but knowing the categories can help you have a more informed conversation with your doctor.
The most common culprits include:
- Sleep medications (zolpidem, eszopiclone) and benzodiazepines (diazepam, lorazepam, alprazolam) cause sedation and impair balance, especially with long-term use
- Antidepressants, particularly older tricyclic antidepressants and SSRIs like sertraline and escitalopram
- Blood pressure medications of nearly all types, which can cause drops in blood pressure when you stand up
- Opioid pain medications (oxycodone, hydrocodone), which cause dizziness and sedation
- Antihistamines, especially older ones like diphenhydramine (Benadryl), which cause confusion and drowsiness
- Anti-seizure medications, which can cause dizziness, sedation, and, notably, bone thinning
- Muscle relaxants, particularly baclofen
- Anticholinergic medications used for overactive bladder (oxybutynin) and other conditions
According to GoodRx, taking multiple medications from this list compounds the risk significantly.
Polypharmacy: When More Medications Mean More Risk
Polypharmacy, generally defined as taking five or more medications, is common in older adults. A large study published in BMJ Open found that people taking five or more medications had a 21% higher rate of falls compared to those on fewer drugs. At ten or more medications, the fall rate jumped to 50% higher.
The risk is not just about any single drug. It is about how multiple medications interact, how they compete for the same metabolic pathways in your liver and kidneys, and how their side effects can stack on top of each other. One medication makes you a little drowsy. Another lowers your blood pressure slightly. A third slows your reaction time. Individually, each effect might be minor. Together, they can send you to the floor.
Alcohol Adds to the Equation
This is worth mentioning because it comes up often. Alcohol interacts with many of the medications on the list above, amplifying their sedative effects and further impairing balance and judgment. Even moderate drinking can increase fall risk in older adults, and the effect is magnified when combined with sleep medications, pain medications, or blood pressure drugs.
What I Recommend: A Focused Medication Review
If you have osteoporosis, I strongly encourage you to schedule a focused medication review with your doctor. Not just a quick glance at refills, but a deliberate conversation that covers two questions:
1. Could any of my current medications be affecting my bone health? (Some medications, like certain anti-seizure drugs and long-term corticosteroids, can directly weaken bone.)
2. Could any of my current medications be increasing my risk of falling? (Because for someone with osteoporosis, a fall is not just a fall. It is a potential fracture.)
Ask your pharmacist, too. Pharmacists are often the best resource for spotting drug interactions and side effects that individual prescribing doctors might not catch when each is focused on their piece of the puzzle.
A Critical Caution
Please do not stop any medication on your own after reading this, especially heart medications, blood pressure medications, or seizure medications. Stopping these abruptly can be dangerous or even life-threatening. The goal is not to eliminate necessary medications. It is to work with your doctor to review whether each one is still needed at its current dose, whether safer alternatives exist, and whether the overall combination is as safe as it can be.
Sometimes a small dose adjustment, a switch to a different drug in the same class, or simply timing a medication differently can meaningfully reduce your fall risk without sacrificing the treatment you need.
The Bigger Picture
Falls and the fractures they cause are the real threat of osteoporosis. Building stronger bones matters. But keeping yourself upright matters just as much, and your medication list is one of the most concrete, actionable places to start.
Bring your full medication list, including over-the-counter drugs and supplements, to your next appointment. Ask the questions. Your doctor will appreciate it.
