Editorial Policy

1. Sources we rely on

Every guide is built exclusively from authoritative, primary sources: FDA-approved prescribing information (package inserts), the National Library of Medicine's DailyMed and MedlinePlus, CDC guidance where relevant, and published guidelines from recognized professional societies.

We do not use crowd-sourced health forums, user testimonials, or secondary blogs as evidence. If a claim cannot be supported by one of the primary sources above, it does not appear in a guide.

2. How each guide is produced

Guides follow a fixed structure — quick facts, step-by-step administration, avoidance warnings, and frequently asked questions — so readers always know where to find what they need.

Drafts are written for a general US adult audience at a plain-language reading level, then verified line-by-line against the current drug label. Dosing examples reflect the most common labeled regimens and always defer to the reader's own prescription.

3. Clinical review and fact-checking

Before publication, every guide is fact-checked by a board-certified pharmacist who verifies drug class, dosing conventions, food and interaction rules, contraindications, and warning language against current labeling.

Each page displays a fact-check badge with its review date. The current review cycle completed in August 2026.

4. Update schedule

Guides are re-reviewed at least every 12 months, and immediately when the FDA issues a labeling change, boxed warning, or safety communication affecting a covered medication.

The 'last updated' date on each page reflects the most recent clinical review, not a cosmetic edit.

5. Corrections

If you believe any content is inaccurate or outdated, email [email protected] with the page URL and the detail in question. Clinical corrections are verified against primary sources, prioritized ahead of all other editorial work, and noted on the corrected page.

6. Independence and conflicts of interest

MedGuide USA does not sell or dispense medications, does not accept funding or sponsorship from pharmaceutical manufacturers, and does not permit advertisers to influence content selection or wording. Reviewers must disclose any conflict of interest before being assigned a guide.
