Generic vs Brand-Name Drugs: What's the Difference?
Last updated June 26, 2026 · Reviewed by the LowerScript editorial team · Español
A generic drug contains the same active ingredient, strength and dosage form as its brand-name version and must meet the FDA's bioequivalence standards. Generics typically cost far less — often a fraction of the brand price — because the manufacturer didn't bear the original development cost. Some newer medications are still brand-only, with no generic available yet.
Are generics as effective?
The FDA requires generics to be bioequivalent to the brand, meaning they work the same way in the body. They use the same active ingredient at the same strength.
Why generics cost less
Generic makers don't repay the original research and marketing costs, and competition among multiple generic makers drives prices down.
When only the brand exists
Newer drugs like Ozempic, Mounjaro and Jardiance are brand-only. For these, comparing pharmacy cash prices and using a discount is the main way to save.
Frequently asked questions
Is a generic the same as the brand?
It has the same active ingredient and must be bioequivalent, though inactive ingredients (fillers, dyes) can differ.
Why is the generic so much cheaper?
Generic makers avoid original development costs and compete on price.
What if there's no generic?
Compare cash prices across pharmacies and use a discount card to lower the brand cost.
