What are generic drugs, and why are they sometimes less expensive?

The biggest difference between generic and brand-name drugs is the price. Generic drugs might cost you significantly less than your equivalent brand-name medicines.¹ Because of this, generic drugs are a popular option for many patients. Currently, they make up about 90 percent of prescriptions filled in the United States.⁴

Aside from cost, there are some additional differences between generic and brand-name medicines you want to be aware of. 

Compared to their brand-name counterparts, generic drugs:

• Look different from brand-name drugs due to trademark laws¹
• May have different colors and flavorings¹
• May contain other differences that do not affect the performance, safety or effectiveness of the medicine⁵

Generic drugs tend to cost you less than their brand-name counterparts because the companies that apply to manufacture generic drugs do not have to repeat the animal and clinical (human) studies that were required of the brand-name medicines to demonstrate their safety and effectiveness.¹ Because these tests can be very expensive, the reduction in up-front research cost for generic drugs means that they are able to be sold to you at a substantial discount.
