Original manufacturers are given a patent for their drug to protect their investment, including research, development, and marketing costs. A generic drug is not available until that patent expires, about 20 years after the patent is received. Once a generic version is available, competition helps keep costs down even more.

This means that, even though the shape and size of a generic pill may differ from the brand-name pill you’re used to, it should work the same in the body.
