What are Propecia and Finasteride?

Propecia is a Brand name for its generic equivalent Finasteride. Both Finasteride and Propecia will contain 1mg of the active ingredient Finasteride. They are used to treat hair loss in men known as male pattern baldness (also known as androgenetic alopecia). 

Higher doses of finasteride are used to treat prostate problems such as benign prostatic hyperplasia (BPH) in men, so it is important to take the correct daily dosage for hair loss treatment, 1mg.

In the UK, these medicines are not normally available on the NHS for hair loss, so you would need a private prescription from your doctor or via our online consultation.

How do Propecia and Finasteride work?

In male-pattern hair loss, the scalp contains miniaturized hair follicles and an increased amount of the androgen dihydrotestosterone (DHT).  DHT levels in the scalp are directly responsible for shrinking the hair follicles resulting in hair thinning and falling out. By blocking the conversion of testosterone to DHT, Propecia and finasteride effectively block a process that causes the shrinking of the hair follicles in the scalp, stopping hair loss and giving way the healthy hair growth.

Both versions are most effective in men with hair growth in thinning areas, but not once an area is completely bald. This is because the hair follicle needs to be live and still growing at least thin hairs.

Is Finasteride the same as Propecia?

To understand the answer to this question, we must first answer another: What is the difference between brand name medicines and generic medicines?

When a pharmaceutical company researches, develops, manufactures and markets a new medicine, they adopt a branded name for the medicine and apply for a patent which allows them exclusivity over the medicine until the patent runs out.

When the patent is nearing its expiration date, other manufacturers can apply for a licence to make and distribute their own versions, a generic version, of the medicine.

With all the hard work of research and development already done for them, these generics manufacturers are able to offer the non-branded equivalents of the medicine at a much cheaper price.  The competition between these companies drives the price down even further.

The Medicines and Health products Regulatory Agency (MHRA) in the UK and the Food and Drug Administration in the US are responsible for making sure that the quality and efficacy of the generic products made by these different manufacturers is the same as the original branded medicine.

As a result, generic drugs are exactly the same as the original brand in terms of the medicine, strength, indication (what it is being used for), quality and route of administration.  As these medicines have the same effect but are cheaper, the NHS encourages doctors to prescribe generic medicines over branded medicines, if a generic is available.

It is important to note, however, that although generic medicines have the same active ingredients as the original brand, often the non-active ingredients, or excipients, can be different.  This is why different versions of the same generic medicine often differ in flavour, colour, shape or size to one another.

As the active ingredient and strength are exactly the same, these differences in non-active ingredients should not have any adverse effect on a person’s treatment however theoretically it is possible.  For example, some medicines in the UK, such as those for epilepsy, are prescribed by the brand, as even slight changes in how quickly a medicine is absorbed can have an effect on certain patients’ treatment.

A good example of the brand vs generic scenario is when Pfizer created Viagra for erectile dysfunction.  It is a very well known and recognised brand name of the medicine sildenafil. This gave Pfizer the chance to successfully market the medicine under the name Viagra, to differentiate their original product from the generic versions of sildenafil which would become available after the patent expired.  Even though many manufacturers make sildenafil now, this treatment is still best known under the brand Viagra, as a result of Pfizer’s very successful marketing campaign.

So to answer the original question- is finasteride the same as Propecia?  The answer is yes. However, as Propecia is the branded version of the medicine, it is more expensive than the generic equivalents.

How long do Propecia and Finasteride take to work?

At the recommended dose of one tablet (1mg) daily, the treatment should take between 2 to 6 months to start working.  If there is no effect after 12 months, the treatment should be discontinued.

Continuous once daily use is required to sustain benefit.  If treatment is stopped, the beneficial effects start to wear off after 6 months with a return to normal levels of hair loss by 9 to 12 months.  

What are the side effects of Propecia vs Finasteride?

Like with any medicine, there is a potential for some men to experience side effects. As they contain the same active ingredient at the same strength, they both have the same potential side effects. The MHRA has advised that patients who develop depression or suicidal thoughts whilst taking Propecia or finasteride should stop the treatment immediately and inform a healthcare professional.

The potential side effects of finasteride and Propecia can include:

Uncommon (up to 1 in 100)

  • Sexual dysfunction (including erectile dysfunction and ejaculation disorder)

Frequency unknown

  • Breast abnormalities (swelling or tenderness); skin reactions (including swelling); Angioedema (swelling); depression; male infertility; palpitations; testicular pain

Comparing the cost of Finasteride vs Propecia

As mentioned above, the large cost difference between Propecia versus Finasteride is due to the parent company behind Propecia recovering the costs of the research and development for the medicine, leading to a significantly higher wholesale cost.

Will Propecia and Finasteride give the same results?

There is no difference between Propecia and finasteride in terms of their strengths and active ingredients and therefore their results.  As the non-active ingredients can vary depending on the manufacturer, there may be a subtle difference in side effects, however, the main effect on hair loss is unlikely to vary.  With up to 9 out of 10 men experiencing positive results, Propecia and finasteride remain an equally effective treatment for male pattern hair loss.
