Are generic drugs as effective as the brand?

The FDA requires generics to be bioequivalent to the brand — same active ingredient, strength, dosage form, and route of administration — and to meet the same quality standards. Inactive ingredients can differ.

Why is the brand-name version usually more expensive?

The original manufacturer recovers research and marketing costs and holds a patent for a period. Once patents expire, multiple manufacturers can make the generic, and competition lowers the price.

What the pharmacy pays

$0.06per mL

This is not your price.It is NADAC — the CMS national-average price pharmacies pay to acquire this drug. What you are charged is set after that by your insurer, your deductible and the pharmacy’s markup, and is usually higher. Why the two numbers differ.

Will the generic actually cost you less?

Usually — but we will not put a number on it, because we do not have an honest one. The price we publish is the CMS NADAC survey, and CMS prices the molecule: Cetirizine Hydrochloride Allergy and its generic carry the identical acquisition figure in that data. What differs is everything that happens after the pharmacy buys it — your plan’s formulary tier, your copay, and the pharmacy’s markup. That is where the saving comes from, and nobody publishes those numbers.

So: ask the pharmacist for the generic price and the brand price before you fill it, and ask what the cash price is if it beats your copay — for cheap generics it often does. What your pharmacy actually paid.
