Trusted medication & supplement information, written and reviewed by licensed pharmacists
HelloPharmacist exists to give you clear, honest, evidence-based answers about your medications and supplements — the kind of guidance you'd get from a pharmacist who actually has time to explain. Everything here is grounded in authoritative clinical data and reviewed by a licensed PharmD.
Plain-language answers you can actually trust
Medication and supplement information online is often vague, contradictory, or written to sell you something. We built HelloPharmacist to be the opposite: a place where a real, licensed pharmacist answers your question directly, explains the "why" in plain English, and shows you exactly where the information comes from.
We combine the everyday experience of practicing pharmacists with the same authoritative drug and supplement databases used by hospitals and clinicians across the United States. Whether you're checking an interaction, looking up a drug, or asking a question of your own, our goal is the same — give you accurate, current, well-sourced information and never pretend to be a substitute for your own healthcare provider.

Our editorial & medical review process
Every piece of medical content follows the same disciplined path before it reaches you — and it's revisited on a schedule so it stays current.
Written from authoritative sources
Content is drafted from licensed clinical databases and primary references — never copied from random websites. Every safety claim is tied to a citation.
Reviewed by a licensed pharmacist
A licensed, U.S.-registered pharmacist — different from the original author — reviews and edits the content for medical accuracy before it's published.
Refreshed on a schedule
Our drug and supplement data is re-synced from its sources on a recurring cadence (weekly to monthly), and content is re-reviewed at set intervals so it doesn't go stale.
Found something that looks wrong? Accuracy is everything on a health site. If you spot an error or omission, please contact us — we review every report and aim to respond and correct genuine issues within 24 hours.
Where our information comes from
We don't ask you to just take our word for it. Our tools are built on the same authoritative, professionally maintained databases that hospitals, clinicians, and regulators rely on. Here's exactly what we use.
Natural Medicines
The gold-standard, evidence-graded database for dietary supplements and herbs — powering our drug–supplement and herbal interaction ratings, pregnancy & lactation safety data, and the references behind each rating. Accessed under license.
Dietary Supplement Label Database (DSLD)
The U.S. National Institutes of Health's official database of dietary-supplement product labels. It's the source of truth behind the supplement products, brands, and ingredient panels you search on our site.
RxNorm
The NLM's normalized naming system for clinical drugs. It standardizes drug names across our tools so the same medication maps cleanly across every data source — the backbone of accurate search and cross-referencing. (Drug interactions come from our dedicated interaction sources, not RxNorm.)
NDC Directory & Structured Product Labels
Official U.S. Food & Drug Administration data — National Drug Codes, labeler and packaging details, and the FDA-approved Structured Product Labeling — behind our NDC, GPI, and product-lookup tools.
MedlinePlus Connect
Consumer-friendly drug and health information from the NIH's National Library of Medicine, linked to drug codes to enrich our medication pages with trusted patient-facing explanations.
HCPCS (J-Code) Descriptors
Official Healthcare Common Procedure Coding System descriptors from the Centers for Medicare & Medicaid Services, powering our J-code drug lookup for billing and reimbursement reference.
Gold Standard Drug Database (GSDD)
Licensed clinical drug content — drug overviews and interactions — used by more than 1,500 U.S. hospitals and 35,000 pharmacies. Displayed on HelloPharmacist with permission under a non-exclusive license.
Wherever we make a specific safety claim, we cite it. Throughout our articles and interaction pages you'll find inline references and links that point back to these sources, so you can verify anything for yourself.
How we use AI — and how we don't
We use modern AI to help make dense clinical information easier to read — but on a health site, transparency about that matters. So here's the straight version:
AI helps draft plain-language explanations from our licensed, sourced data — it isn't asked to make up medical facts.
A licensed pharmacist sets the standards for and oversees this content. AI assists our pharmacists; it never replaces them.
Our Pharmacist AI answers by retrieving from our own sourced knowledge base, with citations — not from the open internet.
No tool here — AI or otherwise — is a replacement for your physician or pharmacist. AI is a way to help us explain things clearly and quickly, always on top of trustworthy data and human pharmacist oversight.
Our commitments to you
Accuracy first
Authoritative sources, pharmacist review, and a fast correction process. If it isn't well-supported, we don't publish it.
Transparent & cited
We tell you who wrote it, who reviewed it, where the data came from, and link to the sources so you can check our work.
Privacy-respecting
Ask a question without creating an account. We don't sell your data, and we don't share the email you give us.
