In modern healthcare, an aging parent often sees three or four different specialists. The cardiologist prescribes something for blood pressure, the neurologist prescribes something for memory, and the primary care doctor prescribes an antidepressant—while your parent picks up over-the-counter pain relievers at the grocery store.
During a rushed 15-minute appointment, doctors rarely have time to cross-reference six or seven drugs prescribed by other providers.
In my latest video walkthrough, I take you to my computer screen to show you how to use professional-grade clinical tools to audit a medication list.
Last week, I showed you 3 types of drug interactions. Go and watch that here if you missed it.
Step 1: Fire Up the Medscape Interaction Checker
You don’t need a medical degree or expensive software to check for drug-drug interactions.
Go to Google and search for “Medscape Interaction Checker.”
Click the free Medscape tool.
Type in every single prescription and over-the-counter medication your parent takes daily.
Step 2: The “Real World” Senior Regimen (7 Interactions Hidden in Plain Sight)
In the video, I put in a very common real-world regimen for an older adult:
Dabigatran (Blood thinner for AFib)
Lisinopril (Blood pressure)
Verapamil (Blood pressure)
Furosemide / Lasix (Fluid retention/edema)
Bupropion (Antidepressant)
Ibuprofen (Over-the-counter for joint pain)
The Result: Medscape instantly flagged 7 drug interactions.
The Kidney Danger: Lisinopril, Furosemide, and Ibuprofen all target kidney function. Taking all three creates compound stress on aging kidneys.
The Bleeding Risk: Verapamil increases the potency of Dabigatran in the body, while Ibuprofen adds its own anti-clotting effects—dramatically raising the risk of severe internal bleeding.
Step 3: The Simple Clinical Fix
Even if someone has been on a regimen like this for a long time without an obvious emergency, the potential for a sudden crisis is high.
Watch what happens when we make one simple swap: Removing Ibuprofen and replacing it with Acetaminophen (Tylenol) for joint pain.
Because Acetaminophen doesn’t filter through the kidneys or interfere with blood thinners the way NSAIDs (Ibuprofen) do, the serious kidney and bleeding interactions drop off the board immediately.
Step 4: Testing a New Prescription
The most critical time to use an interaction checker is when a doctor hands you a brand-new prescription.
In the video, we added Erythromycin (a common antibiotic and powerful enzyme inhibitor) to our updated list. Immediately, the system threw a major warning: “Serious - Use Alternatives.”
The 30-Second Script for Your Pharmacist
If an interaction tool flags a Serious or Use Alternative warning on a new or existing prescription, do not panic—and do not stop a prescription cold turkey.
Instead, bring the list to your pharmacist or doctor and use this exact script:
“I ran my parent’s current medication list through an interaction tool and noticed a serious flag between [Drug A] and [Drug B]. I wanted to bring this to your attention to make sure we’ve reviewed this specific interaction—is there a safer alternative we can use?”

Keep advocating, and let’s keep them safe—one pill at a time.
