How we work
How every page is sourced
This site is compiled by an independent editor, not a doctor. So instead of asking you to trust us, we show you where each fact comes from.
Read the editorial policy- 1. The official label first
Facts come from FDA-approved prescribing information and the maker's Instructions for Use for your exact pen or vial.
- 2. Linked, not paraphrased
Every health statement carries a numbered link to its source, and exact wording is quoted where it matters.
- 3. Dated and re-checked
Each page shows when it was updated and which label revision it used. When a label changes, we re-check.
