Generic vs Brand Medicine: A U.S. Consumer Guide
Generic name, brand name and manufacturer
The generic name identifies the active drug ingredient, while a brand name identifies a marketed product. Different manufacturers may produce generic versions that meet regulatory requirements but can differ in inactive ingredients, appearance and packaging.
Formulation still matters
Immediate-release and extended-release products, dosage forms and strengths should not be treated as interchangeable simply because the generic ingredient is the same.
What to ask a pharmacist
If a refill looks different, ask the pharmacist to confirm the manufacturer, active ingredient, strength and formulation before use. Do not change how a prescribed product is taken based on appearance alone.
When professional help matters
Use a pharmacist or prescribing clinician for medicine-specific questions. For a life-threatening reaction or suspected overdose, call 911. This resource is educational and not individualized medical advice.
