Propecia is a brand of Finasteride, and finasteride is the active ingredient in the treatment. The main differences between the two are appearance and price. Finasteride is a generic medication, so it may be slightly cheaper than Propecia, and the packaging and the way the pill looks may differ as a result.
Although Propecia and Finasteride contain the same active ingredient, they do contain different inactive ingredients. It’s unlikely you would get side effects on one and not the other. But if you experience any side effects, you should discuss these with our clinician. These side effects are rare, but they may be key to which of the two treatments is most suitable (and safe) for you to use.
