Mi az a Propecia (Finasteride)?
Propecia (finasteride 1 mg) is a prescription-only oral medicine approved by the European Medicines Agency (EMA) for the treatment of androgenetic alopecia — male pattern hair loss — in adult men. It is a 5-alpha reductase inhibitor, a class of medicines that works at the hormonal level to address the underlying cause of male pattern baldness.
Male pattern hair loss is the most common form of hair loss in men, affecting up to 50% of men by the age of 50. It is driven primarily by the action of dihydrotestosterone (DHT) on genetically susceptible hair follicles.
Hogyan hat a Propecia (Finasteride)?
Finasteride inhibits the enzyme 5-alpha reductase type II, which is responsible for converting testosterone into dihydrotestosterone (DHT) in the scalp, skin, and prostate. DHT is the primary hormonal driver of androgenetic alopecia: it binds to androgen receptors in hair follicles, causing progressive miniaturisation — the gradual shrinking of the follicle until it can no longer produce visible terminal hair.
By inhibiting 5-alpha reductase type II, finasteride reduces scalp and serum DHT concentrations by approximately 60–70%. This reduction slows or halts the miniaturisation process, allowing the follicle to recover and produce thicker, longer hair over time.
Propecia addresses the hormonal cause of male pattern hair loss, distinguishing it from topical treatments such as minoxidil, which act through a different (vascular and proliferative) mechanism.
Kinek ajánlott a Propecia (Finasteride)?
Propecia is indicated for adult men with androgenetic alopecia (male pattern hair loss). It is most effective when started earlier in the course of hair loss — before significant follicle miniaturisation has occurred — but clinical evidence supports benefit at various stages of hair loss.
Propecia is specifically approved for use in men. It is not approved for use in women or children.
Finasteride is not appropriate for all men. A medical assessment is required to confirm suitability. Contraindications include:
- Known hypersensitivity to finasteride or any excipient
- Women of childbearing potential must not handle crushed or broken finasteride tablets — finasteride can be absorbed through the skin and may cause abnormalities in the external genitalia of a male foetus
Adagolás
Propecia is taken as a 1 mg oral tablet once daily, with or without food. It should be taken at approximately the same time each day.
| Dose | Frequency | Notes |
|---|---|---|
| 1 mg | Once daily | Standard approved dose for androgenetic alopecia |
There is no titration period — treatment begins at the full therapeutic dose. The benefit of finasteride is dependent on continued use. Clinical evidence shows that hair counts return to pre-treatment levels within 12 months of stopping the medicine.
Results are typically not visible until 3 to 6 months of consistent use, and full assessment of the medicine’s effect should be made after at least 12 months of treatment.
Mellékhatások
As with all medicines, Propecia may cause side effects. The majority of men taking finasteride do not experience side effects.
Common side effects (may affect more than 1 in 100 people)
- Decreased libido (reduced sex drive)
- Erectile dysfunction
- Ejaculatory disorders (reduced volume of ejaculate)
These sexual side effects were reported in a small proportion of men in clinical trials (approximately 1–2%) and resolved in most patients after discontinuation of treatment. They may also improve with continued use in some men.
Kevésbé gyakori, de figyelemre méltó hatások
- Breast tenderness or enlargement (gynaecomastia) — rare but reported
- Hypersensitivity reactions including rash, urticaria, or swelling of the lips and face
- Testicular pain (uncommon)
Post-market reports
Post-market surveillance data and the medical literature include reports of persistent sexual dysfunction (including reduced libido and erectile dysfunction), depression, and cognitive effects in a small number of patients following discontinuation of finasteride. This is referred to in the literature as post-finasteride syndrome (PFS). The EMA has reviewed this safety signal, and prescribing information in the EU includes relevant warnings. Patients should discuss any personal or family history of mood disorders or sexual dysfunction with their doctor before starting treatment.
Prostate-specific antigen (PSA)
Finasteride reduces serum PSA levels by approximately 50%. Men on finasteride who undergo PSA screening for prostate cancer should inform their doctor, as the reduced PSA value must be interpreted accordingly (typically by doubling the result to estimate the true PSA level).
Propecia (Finasteride) vs alternatívák
The two primary treatments for male pattern hair loss approved in Europe are finasteride and minoxidil. They have distinct mechanisms of action and can, in some cases, be used in combination under medical supervision.
| Treatment | Active Ingredient | Mechanism | Form | Indication |
|---|---|---|---|---|
| Propecia | Finasteride 1 mg | 5-alpha reductase inhibitor (hormonal) | Oral tablet | Male androgenetic alopecia |
| Rogaine | Minoxidil | Vasodilator / hair follicle stimulant | Topical solution or foam | Androgenetic alopecia (men and women) |
Főbb különbségek:
- Propecia vs Rogaine (Minoxidil): Finasteride acts on the hormonal cause of hair loss (DHT reduction), while minoxidil stimulates blood flow to hair follicles through a vascular mechanism. Finasteride is taken orally once daily; minoxidil is applied directly to the scalp once or twice daily. Finasteride is approved for men only; minoxidil is approved for both men and women. Both have demonstrated effectiveness in clinical trials, and some men use both concurrently under medical supervision for complementary effects.
- Treatment duration: Both require continuous use to maintain benefit. Stopping either treatment typically results in reversal of hair loss gains within 12 months.

Frequently asked questions
- Mire használják a Propecia (Finasteride)?
- Propecia (finasteride 1 mg) is approved by the European Medicines Agency (EMA) for the treatment of androgenetic alopecia — commonly known as male pattern hair loss — in adult men. It is used to slow hair loss and, in many cases, to promote some regrowth of hair in areas affected by thinning.
- Mennyire hatékony is Propecia for hair loss?
- Clinical trials submitted to the EMA demonstrated that finasteride 1 mg stopped the progression of hair loss in approximately 90% of men over two years of treatment. Around two-thirds of men experienced measurable hair regrowth during the same period. Results are typically seen after 3 to 6 months of consistent use, and continued treatment is required to maintain the benefit.
- Mennyi ideig does it take for Propecia to work?
- Most men begin to notice a reduction in hair shedding within 3 to 6 months of starting treatment. Visible hair regrowth, where it occurs, is typically apparent after 6 to 12 months. Propecia must be taken daily and continuously — discontinuing treatment usually results in a return to baseline hair loss within 12 months.
- Megkaphatom a Propecia (Finasteride) készítményt online Európában?
- A készítményhez online közvetítő platformokon keresztül férhet hozzá, amelyek független, EU-ban regisztrált orvosokkal kötik össze Önt. A bizalmas egészségügyi kérdőív kitöltése után az orvos felméri, hogy a gyógyszer klinikailag megfelelő-e az Ön számára.
- Does Propecia cause sexual side effects?
- Clinical studies found that a small proportion of men (approximately 1–2%) experienced sexual side effects including decreased libido, erectile dysfunction, or reduced ejaculate volume. These effects were reported to resolve in most patients after discontinuation of treatment. Some reports in the medical literature describe persistent sexual side effects in a small subset of patients after stopping finasteride (post-finasteride syndrome), though the clinical evidence base for this remains under investigation. All relevant health history should be disclosed to the reviewing doctor before starting treatment.
