Walk into a pharmacy and you may see two medicines with dramatically different names and prices even though both contain the same active ingredient. One may be the original brand. The other may be a generic.
So what is actually different?
What Is an Active Ingredient?
The active ingredient is the substance responsible for a medicine’s intended pharmacological effect. A medicine may also contain inactive ingredients used for binding, coating, coloring, flavoring, preserving or manufacturing.
Explore individual ingredients through the MyRxBox Medicine Glossary.
What Is a Brand-Name Medicine?
A brand-name medicine is marketed under a proprietary commercial name. The brand may become so familiar that people use it as if it were the drug name itself, but the generic name identifies the active ingredient.
What Is a Generic Medicine?
A generic medicine is intended to provide the same clinical benefit as an approved reference medicine. For FDA approval in the United States, a generic generally must have the same active ingredient, strength, dosage form and route of administration and meet bioequivalence requirements.
Can Generic Medicines Look Different?
Yes. Generic products may differ in shape, color, packaging and certain inactive ingredients. Appearance alone does not tell you whether the active medicine is different.
Identify a medicine from its official label rather than color or shape alone.
Why Can Generic Medicines Cost Less?
Developing a completely new medicine requires extensive research and clinical development. Generic manufacturers can rely on established findings for the reference medicine while still satisfying generic approval requirements. Competition among manufacturers can also reduce prices.
Compare pricing through the Medicine Price Index.
Is a More Expensive Medicine Automatically Better?
No. Price alone is not a measure of clinical quality. Likewise, a lower price does not automatically prove that two products are equivalent.
Check the active ingredient, strength, dosage form, manufacturer, regulatory status, source and label.
What Are Branded Generics?
A branded generic is a generic medicine sold using a commercial brand name. This can create confusion because patients may assume every brand represents a completely different molecule.
The active ingredient is usually the most useful starting point.
Can Inactive Ingredients Matter?
Sometimes. Inactive ingredients normally do not provide the primary therapeutic action, but particular patients may need to consider them because of allergies, sensitivities or other individual circumstances. Ask a pharmacist or healthcare professional when this is relevant.
Brand vs Generic Comparison
| Item | Brand | Approved Generic |
|---|---|---|
| Active ingredient | Specified on label | Matches reference active ingredient |
| Strength | Specified | Matches approved reference strength for the product |
| Dosage form | Specified | Matches reference dosage form |
| Appearance | May differ | May differ |
| Inactive ingredients | Can vary | Can vary |
| Price | Varies | Often lower, but varies |
Do Not Switch Based Only on an Internet Article
There are clinical circumstances in which the exact product, release mechanism or formulation matters. Do not independently replace a prescribed medicine just because another product appears to contain the same ingredient.
Ask your pharmacist or prescriber.
