Frequently Asked Questions

Where does PlainMeds get its drug information?

All information comes from official FDA databases: Structured Product Labeling (SPL) for drug labels, the FDA Adverse Event Reporting System (FAERS) for real-world side effect reports, and FDA Drug Enforcement Reports for recall information. We do not use third-party data, unverified sources, or fabricated medical claims.

What is Structured Product Labeling (SPL)?

SPL is the official FDA format for drug labeling submitted by pharmaceutical manufacturers. It is the same detailed labeling your pharmacist reads and covers indications (what a drug is approved for), dosage instructions, warnings, contraindications, drug interactions, adverse reactions, and storage requirements.

Are the adverse event counts on a drug's page dangerous thresholds?

No. Adverse event counts from FAERS reflect the number of reports submitted to the FDA, not the rate of adverse events per population of users. A drug used by millions of people will generate more reports than a rarely-used drug even if neither is comparatively unsafe. FAERS data is useful for awareness and discussion with your doctor, not for comparing drug safety.

What does an active recall record show?

A PlainMeds recall record links the associated FDA notice and identifies the source-record class, affected lots where available, reason, and date. Recall records do not provide an individual medication response direction.

Why does my drug's label information look different from what's in the package insert?

PlainMeds translates complex medical language into plain English summaries to improve readability. The underlying factual data comes directly from the FDA SPL, but you may notice differences in wording. For official prescribing information, always refer to the current package insert or FDA labeling, which we link to on each drug page.

Can I search for a medication by active ingredient?

Yes. PlainMeds indexes drugs by brand name, generic name, and active ingredient. If you search for an active ingredient like ibuprofen, you'll find all brand-name and generic products containing that ingredient.

What do the drug interaction severity levels mean?

PlainMeds labels documented drug interactions as minor, moderate, or major, following the compiled FDA Structured Product Labeling severity field. The category describes a source record, not an individual risk estimate, monitoring plan, or medication-combination direction.

How often is PlainMeds data updated?

PlainMeds refreshes its database periodically from the official sources. FDA drug labeling (SPL) updates continuously as manufacturers submit revisions, FAERS adverse-event data is published quarterly by the FDA, recall and shortage data update as the FDA issues new actions, and CMS NADAC pricing is released weekly. Each data page shows when its underlying figures were last compiled.

Are the drug prices on PlainMeds accurate?

The prices come from the CMS National Average Drug Acquisition Cost (NADAC), the federal benchmark for what retail pharmacies pay to acquire a medication. NADAC is an acquisition-cost benchmark, not the retail price you pay at the counter. Your out-of-pocket cost depends on your insurance, pharmacy, and any discounts, so treat these figures as a consistent way to compare medications rather than a quote for your prescription.

Is PlainMeds connected to the FDA or any pharmaceutical company?

No. PlainMeds is an independent project and is not affiliated with the FDA, any pharmaceutical company, or any healthcare organization. We present publicly available FDA data to help people understand their medications more easily.
