That’s why you’ll find so many of our posts tie back to MedlinePlus, a free, official U.S. government service run by the National Library of Medicine. Also known as NIH’s patient health portal, it’s the go-to source for millions who want facts—not marketing.. Think about it: when we talk about the FDA Orange Book, FDA Orange Book, the official list of approved generic drugs and their therapeutic equivalence ratings, we’re referencing the same database MedlinePlus pulls from. Same with black box warnings, the FDA’s strongest safety alerts for life-threatening drug risks—they’re published first by the FDA, then explained clearly on MedlinePlus. Even drug interaction tables, detailed charts in prescribing labels that show dangerous combinations? You’ll find simplified versions of those on MedlinePlus, so you don’t need a medical degree to understand them.

What makes MedlinePlus different? It’s not flashy. It doesn’t have ads. It doesn’t pretend to be a pharmacy. It’s the quiet, reliable library in the background of every serious health decision. If you’re trying to figure out if your generic pill is safe to swap, why your doctor warned you about mixing meds, or what those weird side effects mean—MedlinePlus is where you start. And because our posts dig deep into real-world use cases—like how fiber blocks levothyroxine, why PPIs and H2 blockers shouldn’t be stacked, or how insulin biosimilars compare to brand names—you’re seeing the practical side of what MedlinePlus lays out in plain language.
