Explorer

Is the cheaper one the same thing?

Name: OTC Equivalence Explorer
Creator: Salvio
License: https://www.fda.gov/about-fda/about-website/website-policies

Salvio compares the active ingredient, its strength, and the dosage form as filed with the FDA. Where those three match, the products are the same drug — whatever the box costs. That is the whole claim, and it is not a statement that two products are medically interchangeable for you.

This is a capped first wave, not everything Salvio holds. A group earns a page only when at least three distinct companies label it, a recognisable brand anchors it, and enough of its products have an FDA label on file to say something useful. How the grouping works →
