The primary difference is typically the cost, with generics generally being more affordable.
Why Are There So Many Generic Manufacturers?
The approval of multiple generic manufacturers for a drug like Wellbutrin XL indicates that the market has opened up for competition. This occurs when the patents protecting the brand-name drug have expired or have been successfully challenged, allowing other pharmaceutical companies to produce and sell their versions of the medication. Increased competition often leads to lower prices for consumers.
