Finasteride 1mg and 5mg tablets — generic Propecia and Proscar — for licensed medical practices. Prescription DHT blocker for male pattern hair loss and benign prostatic hyperplasia (enlarged prostate).
Finasteride — generic Propecia at 1mg, generic Proscar at 5mg — is a prescription medication that reduces DHT (dihydrotestosterone), the hormone responsible for male pattern hair loss and prostate growth. At the 1mg dose, it slows or stops hair loss and promotes regrowth in men with androgenetic alopecia. At the 5mg dose, it reduces prostate size and improves urinary symptoms in men with benign prostatic hyperplasia (BPH). Available in both strengths for licensed medical practices. Rx only.
| Strength | Brand equivalent | FDA-approved indication | Standard dose |
|---|---|---|---|
| 1 mg | Generic Propecia® | Male pattern hair loss (androgenetic alopecia) | 1mg once daily |
| 5 mg | Generic Proscar® | Benign prostatic hyperplasia (BPH) | 5mg once daily |

DHT is made when the enzyme 5-alpha reductase converts testosterone into a more potent form. In men genetically predisposed to hair loss, DHT miniaturizes hair follicles over time — making hair thinner and shorter until it stops growing entirely. In the prostate, DHT drives the tissue growth responsible for BPH.
Finasteride blocks 5-alpha reductase, which reduces DHT levels by approximately 70%. Less DHT means slower follicle miniaturization and, for many men, visible hair regrowth or stabilization of existing hair. In the prostate, lower DHT levels lead to a measurable reduction in prostate volume over months of treatment, improving urine flow and reducing BPH symptoms.
| Finasteride 1mg (Generic Propecia) | Finasteride 5mg (Generic Proscar) | |
|---|---|---|
| FDA-approved use | Male pattern hair loss | Benign prostatic hyperplasia (BPH) |
| Target patient | Men with androgenetic alopecia | Men with symptomatic BPH |
| Results timeline | 3-6 months for initial results; 12 months for full effect | 6-12 months for prostate volume reduction |
| Discontinuation effect | Hair loss resumes within 12 months of stopping | BPH symptoms return after stopping |
Both doses work through the same mechanism. The difference is the clinical indication and the dose required to achieve the desired effect.
Men’s health and TRT practices: Finasteride is commonly prescribed alongside testosterone therapy — particularly for men concerned about DHT-related hair loss acceleration that can occur when testosterone levels rise on TRT. At 1mg, it manages hair loss as part of the broader men’s health protocol.
Hair loss and dermatology-adjacent practices: Finasteride 1mg is a first-line prescription treatment for male pattern hair loss, used in practices offering medical hair loss management alongside topical treatments like minoxidil.
Urology-adjacent practices: Finasteride 5mg for BPH management, either as a standalone treatment or combined with an alpha-blocker for patients with larger prostates and significant urinary symptoms.
Primary care and functional medicine practices: Both indications arise regularly in primary care — hair loss in men in their 30s and 40s, and BPH in men over 50. Practices that prescribe finasteride in-house provide a more complete men’s health service.
Tadalafil Tablets (5mg / 10mg / 20mg) — Finasteride and tadalafil are the two components of Entadfi® — the brand-name combination product for BPH and ED. Practices managing men with concurrent BPH and erectile dysfunction can prescribe both components separately, addressing both conditions in a single men’s health protocol. The pairing is also clinically relevant for TRT practices where both sexual function and hair/prostate management are part of the offering.
DHEA 25mg Capsules — Adrenal hormone precursor support alongside the DHT management finasteride provides. For practices taking a comprehensive hormonal approach to men’s health.
Gonadorelin Peptide Injection — HPG axis support for TRT practices. Gonadorelin maintains endogenous LH and FSH signaling; finasteride manages DHT-mediated side effects of elevated androgens. A common combination in comprehensive TRT protocols.
Anastrozole 1mg Tablets — For TRT practices managing the full androgen-to-estrogen conversion picture. Anastrozole manages estradiol from testosterone aromatization; finasteride manages DHT from testosterone reduction. Both address off-target androgen effects without reducing testosterone itself.
PSA suppression — must document: Finasteride reduces PSA by approximately 50%. Any PSA result in a patient on finasteride should be doubled to estimate the true value. Failure to account for this can mask a clinically significant PSA elevation. Document finasteride use in every patient’s record and communicate it to all providers ordering PSA tests.
Handling by women who are pregnant or may become pregnant: Finasteride is absolutely contraindicated in pregnancy — it can cause abnormal development of male fetal genitalia. Pregnant women or those who may become pregnant must not handle crushed or broken finasteride tablets. Intact tablets with an intact coating are generally considered safe to handle briefly, but the safest practice is to avoid all handling. This applies to female staff in practices dispensing finasteride.
Sexual side effects: A subset of men on finasteride experience reduced libido, erectile dysfunction, or reduced ejaculate volume. These side effects are dose-dependent and typically resolve after stopping the medication — though a small number of men report persistent symptoms after discontinuation. Counsel patients on this risk before starting treatment.
Post-finasteride syndrome: A small proportion of men report persistent sexual, neurological, and psychological side effects after stopping finasteride. The mechanism is not fully understood and remains an area of ongoing research. Providers should include this in the informed consent discussion.
Prostate cancer screening: Because finasteride suppresses PSA, standard PSA screening thresholds do not apply directly to men on this medication. A urological evaluation is appropriate if the doubled PSA value crosses clinical thresholds or if other prostate cancer risk factors are present.

What is the difference between finasteride 1mg and 5mg?
The 1mg dose is FDA-approved for male pattern hair loss and is the standard prescription for men seeking to slow or reverse androgenetic alopecia. The 5mg dose is FDA-approved for BPH and is used to reduce prostate size and improve urinary symptoms. Both work through the same DHT-blocking mechanism — the difference is the clinical indication and the dose required to achieve it.
How long does finasteride take to work for hair loss?
Initial results typically appear at 3-6 months. Full effect takes up to 12 months. Hair loss resumes within 12 months of stopping treatment — finasteride works only as long as it is being taken. This is an important point to communicate to patients before starting so expectations are aligned.
Why does finasteride affect PSA test results?
Finasteride reduces DHT-driven prostate activity, which lowers PSA production. PSA levels drop by approximately 50% in men on finasteride. Since PSA is used to screen for prostate cancer, providers must double the measured PSA value to get an accurate clinical picture. Any provider ordering PSA for a patient on finasteride needs to know about the medication.
Is a prescription required?
Yes. Finasteride is Rx only, available exclusively to licensed healthcare providers and medical practices.
