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.

Generics are typically far cheaper once the brand's patent expires.
Appearance (shape, color) often differs and that is normal.
