No, but they are very similar. Propecia is a hair loss tablet that contains the same active ingredient (finasteride) and works in the same way in the body. But the two treatments do contain different inactive ingredients, so the side effects that you may get with Finasteride may not be the same as the side effects you can experience with Propecia, and vice versa.
Propecia is also the branded treatment, whereas Finasteride is the generic option. This means that the tablets themselves, and the packaging, may be different. Finasteride, as the generic, is also slightly cheaper.
