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.

Brand vs generic: what to know

A generic drug contains the same active ingredient as the brand-name original at the same strength and dosage form. Before approval, the FDA requires it to be bioequivalent — it must work the same way in the body.

Same active ingredient, strength, route, and intended use.
Inactive ingredients (fillers, dyes) may differ — relevant for allergies.
Generics are typically far cheaper once the brand's patent expires.
Appearance (shape, color) often differs and that is normal.
