Propecia and Finasteride both refer to the same drug that treats different forms of alopecia (i.e., hair loss) and benign prostatic hyperplasia (BPH).
The only difference is the branding of the drug. In other words, Finasteride is the active ingredient, whereas Propecia is the brand name of this drug.

Propecia Vs. Finasteride: which is more effective?
Propecia and Finasteride are equally effective in treating male pattern baldness, as they contain the same active ingredient and work by inhibiting DHT formation.
Propecia and Finasteride, though different in branding, share the same active ingredient and mechanism of action, making them equally effective in combating androgenetic alopecia, commonly known as male pattern baldness.
Dermatologists frequently prescribe these drugs, and their efficacy has been well-documented in clinical studies.
In a notable study involving 3177 Japanese men with androgenetic alopecia, participants were administered 1 milligram of Finasteride daily for 3.5 years. The results were promising, with the majority of participants experiencing significant hair regrowth.
Importantly, the study highlighted that the longer the duration of treatment, the better the outcomes in terms of hair growth. Additionally, the incidence of serious side effects was remarkably low, with only 0.7% of participants (23 men) reporting adverse effects.
This evidence underscores the effectiveness of both Propecia and its generic counterpart, Finasteride, in the long-term management of male pattern baldness.
Propecia Vs. Finasteride: Which has more side effects?
Propecia and finasteride are the same hair loss treatment, just with different names.
Similar to the benefits of the two versions, both Propecia and Finasteride cause the same side effects. Consequently, the risk of developing these side effects is quite low.
Since this drug has a steroid base, many people spread some rumors about how it causes sexual dysfunction (e.g., erectile dysfunction, premature ejaculation, decreased libido). While these side effects are possible, their occurrence has been relatively low in clinical reports.
According to a press release from the Food and Drug Administration (FDA), their agents received 421 reports of sexual dysfunction in 13 years. The vast majority of these cases improved after the discontinuation of the drug.
Compared to the overall number of patients who take this drug, the percentage of reported side effects has been relatively low.
Propecia Vs. Finasteride: which one is better?
After covering the benefits, effectiveness, and side effects of Propecia Vs. Finasteride, it is clear that both versions of the drug offer identical responses.
Both Propecia and finasteride work by preventing the conversion of testosterone to DHT. This stops the shrinking of hair follicles and reverses balding.
However, there is one aspect that makes Propecia vs. Finasteride very different – COST.
Typically, the cost of Propecia is around $75-$80 a month. Additionally, most insurance plans do not cover this drug.
On the other end, Finasteride is much cheaper and could be covered by insurance as a Tier 1 medication. Consequently, you may get this drug for as little as a $10-$20 copay.
You might be asking: “You said it’s the same drug, so why is Propecia more expensive?”
The reason for this price disparity boils down to the cost of production. You see, when a company receives a patent for a drug, they possess exclusive rights to produce and sell the drug for a limited period of time (12 years on average).
Once the patent ends, other companies can start producing the generic version.
Therefore, Generic Finasteride is cheap because the company that produces it has the necessary data on the drug’s development and effectiveness (provided by the brand-name company), which cuts costs significantly.

Worry not, as we developed a quick guide on the best alternatives you can take.

Propecia is approved by the MHRA for treating hair loss.

Note that physicians do not prescribe this drug for women or children. [1]
What is Finasteride?
Finasteride is an FDA-approved pharmacologic agent that treats benign prostate hyperplasia and androgenic alopecia. The drug received FDA approval in 1992 for BPH. Six years after, the FDA approved it to treat male pattern baldness.
Finasteride may also be called generic Propecia when it is sold under the brand name.
Note that the dosage used to treat BPH and androgenetic alopecia are different.
