When you walk down the pharmacy aisle, it’s easy to assume over-the-counter medications are harmless. But for older adults, even common drugs can come with serious risks—from dizziness and confusion to dangerous interactions with prescriptions. In fact, millions of seniors experience adverse drug events each year, and more than half involve everyday OTC medications. As we age, our bodies process medications differently, making even “safe” remedies potentially risky. If you or a loved one takes multiple medications, this list could help prevent costly—and sometimes life-threatening—mistakes.
1. NSAID Pain Relievers Like Ibuprofen and Naproxen
Nonsteroidal anti-inflammatory drugs (NSAIDs) are some of the most commonly used medications for pain relief. While they can be effective, they also come with increased risks for seniors, including stomach bleeding and ulcers. These risks are even higher for people taking blood thinners or managing conditions like high blood pressure.
Long-term use can also strain the kidneys and increase the risk of heart complications. Experts recommend using the lowest dose possible and discussing safer alternatives with your doctor.
2. Diphenhydramine (Benadryl) and Sleep Aids
Many seniors turn to antihistamines like diphenhydramine for allergies or sleep, but these can be particularly dangerous. They are known to cause confusion, dizziness, and even memory problems in older adults. These side effects can increase the risk of falls and accidents, which are already a major concern for seniors.
Even combination products like nighttime cold medicines often contain these ingredients without obvious labeling. Experts strongly advise avoiding these medications unless specifically directed by a healthcare provider.
3. Acetaminophen (Tylenol) Overuse
Acetaminophen is widely considered safer than other pain relievers, but that doesn’t mean it’s risk-free. Taking too much—especially when combined with other medications containing acetaminophen—can lead to serious liver damage. Many seniors accidentally exceed the recommended dose because it’s hidden in multiple products.
This is particularly dangerous for those who drink alcohol or have existing liver conditions. Always read labels carefully and track your daily intake to stay within safe limits.
4. Cold and Decongestant Medications
Decongestants like pseudoephedrine and phenylephrine are commonly used to relieve cold symptoms, but they can raise blood pressure and heart rate. For seniors with heart conditions or hypertension, this can be especially risky. These medications can also worsen prostate issues, leading to difficulty urinating. Because they’re often included in combination cold remedies, it’s easy to take them unintentionally. Checking labels and consulting a pharmacist can help you avoid unwanted side effects.
5. Proton Pump Inhibitors for Heartburn
Heartburn medications like omeprazole and lansoprazole are frequently used for long-term relief. However, extended use has been linked to weakened bones, increased fracture risk, and certain infections. Seniors who rely on these medications daily may not realize the long-term consequences. These drugs can also interfere with the absorption of important nutrients like calcium and magnesium. Experts recommend reviewing long-term use regularly with a healthcare provider to determine if they’re still necessary.
6. Laxatives and Digestive Aids
Laxatives might seem harmless, but overuse can lead to dehydration and electrolyte imbalances. Some types, especially those containing magnesium, can be dangerous for seniors with kidney issues. Regular reliance on laxatives may also mask underlying digestive problems that need medical attention. In severe cases, misuse can lead to hospitalization. It’s always best to address chronic constipation with dietary changes or medical guidance instead of long-term laxative use.
7. Motion Sickness and Vertigo Medications
Drugs like meclizine are often used for dizziness or motion sickness, but they can actually worsen balance issues. Side effects like drowsiness and confusion can increase fall risk, which is already a leading cause of injury in older adults. These medications may also exacerbate symptoms in individuals with dementia. Because falls can have serious consequences, even a mild increase in risk is significant. Seniors should only use these medications when absolutely necessary and under medical supervision.
8. Combination Cold and Flu Products
Combination medications are convenient, but they often contain multiple active ingredients that can interact with other drugs. Seniors may unknowingly take duplicate ingredients, increasing the risk of overdose or side effects. For example, a single product might include acetaminophen, antihistamines, and decongestants—all with their own risks. This makes it harder to track what you’re actually consuming. Experts recommend using single-ingredient medications whenever possible to reduce confusion and risk.
Why “Safe” Medications Aren’t Always Safe After 60
As we age, the way our bodies handle medications changes significantly. Slower kidney and liver function can cause drugs to stay in the system longer, increasing the risk of side effects. Taking multiple medications at once—known as polypharmacy—can also lead to dangerous interactions. Even mild side effects like dizziness or confusion can quickly escalate into falls or hospital visits. The key takeaway is simple: always double-check medications, even the ones you’ve used for years, and involve your doctor or pharmacist in every decision.
