generic name

A generic name is the official, non-trademarked name of a drug's active substance, the plain name everyone can use rather than any one company's brand. If a brand name is like a person's nickname that a particular family chose, the generic name is their legal name on official documents, the same everywhere.

The generic name identifies the chemical itself, independent of who manufactures or sells it. It is usually the same as, or derived from, the WHO's international nonproprietary name, and it carries no ownership. Because it reflects the substance and often its drug class through shared stems, the generic name is the name clinicians, pharmacists, and textbooks rely on for clarity and safety.

Generic names matter for both accuracy and cost. Prescribing by generic name lets a pharmacist dispense any equivalent product, supports the use of cheaper generic medicines after a patent expires, and avoids confusion when the same substance is sold under many brands. It is good practice in many systems to think and prescribe in generic names, reserving brand names for situations where the specific product genuinely matters.
