Medication Guides
Plain English explanations of common medication topics — no jargon, no fluff.
What These Guides Cover
PlainMeds publishes 7 editorial guides across four topic clusters — drug-interaction safety (3 guides), cost & access (1 guide on generic substitution), OTC therapeutics (1 guide on pain relievers), and label-literacy plus recall comprehension (2 guides). Every guide is cross-referenced against the same 682-drug reference database that powers per-medication profiles on the site, so a claim made in a guide can be checked against the underlying data: a stated CYP3A4-inhibitor list maps to actual interaction records, a stated recall-class definition maps to actual FDA enforcement records on individual drug pages.
The guides are intentionally narrow rather than encyclopedic: they cover the questions our search analytics surface most often (interaction safety, generic substitution, NSAID vs acetaminophen choice) and the topics where official FDA documentation is dense and patient-unfriendly. Each guide names its primary FDA/CMS data source, links to the relevant detail-page records, and documents what the source cannot tell us — passive reporting limits in FAERS, manufacturing-quality vs efficacy distinctions in recalls, and dispensing-practice variation in generic-substitution outcomes.
Understanding Drug Interactions
What happens when medications don't play well together — types of interactions, common dangerous combinations, and how to protect yourself.
Generic vs Brand Name Drugs
What's actually different between generic and brand name medications — FDA requirements, cost savings, and when it matters.
Pain Relievers Compared
NSAIDs vs acetaminophen — which over-the-counter pain reliever to use for headaches, inflammation, fever, and more.
How Drug Interactions Work
Pharmacokinetic vs pharmacodynamic mechanisms — CYP450 enzymes, enzyme inhibitors and inducers, food-drug interactions, and the FDA severity classification system.
Narrow Therapeutic Index Drugs
Why warfarin, digoxin, lithium, and other NTI drugs demand precise dosing — therapeutic ranges, monitoring requirements, and how generic substitution rules differ.
How to Read an FDA Drug Label
What each section of the official prescribing information means — indications, warnings, contraindications, adverse reactions, and boxed warnings explained.
FDA Drug Recalls Explained
What recall classes mean, why drugs get recalled, how to check if your medication is affected, and what actions to take.
Methodology
Every guide on PlainMeds is derived from three public FDA/CMS datasets: FDA Structured Product Labels (SPL/DailyMed), FDA Adverse Event Reporting System (FAERS), and CMS National Average Drug Acquisition Cost (NADAC).
Factual content — warnings, dosages, contraindications, interaction severity, adverse event counts, acquisition costs — is taken directly from official FDA/CMS databases without modification. editorial plain-language simplification is applied only to produce plain-language summaries alongside the original labeling.
