Finasteride Medications

Finasteride is a synthetic 5-alpha-reductase inhibitor that is widely prescribed for benign prostatic hyperplasia (BPH) and androgen-dependent hair loss in men. By blocking the conversion of testosterone to the more potent dihydrotestosterone (DHT), it reduces prostatic volume and slows the miniaturisation of scalp follicles. The drug is available under well-known brand names such as Proscar (5 mg) and Propecia (1 mg), as well as numerous generic versions that can be purchased through our online pharmacy. In Australia, the Therapeutic Goods Administration (TGA) approved finasteride in 1992 for BPH and later expanded its indication to male pattern hair loss. Although its primary uses are clearly defined, clinicians sometimes apply finasteride off-label for conditions like chronic prostatitis or certain dermatological disorders, provided the evidence supports potential benefit. Understanding finasteride’s pharmacology, dosing options, and safety profile empowers patients to make informed choices while collaborating with their healthcare team.

What is Finasteride?

Finasteride belongs to the class of selective 5-alpha-reductase inhibitors, enzymes that catalyse the conversion of testosterone into dihydrotestosterone (DHT). The TGA first approved the 5 mg formulation for the treatment of benign prostatic hyperplasia in 1992, and the 1 mg formulation received approval for androgenetic alopecia in men in 1997. The United States Food and Drug Administration (FDA) and the European Medicines Agency (EMA) later confirmed these indications, reinforcing its global standing as a cornerstone therapy for prostate enlargement and male-pattern hair loss.

At the molecular level, finasteride binds competitively to the type II isoform of 5-alpha-reductase, situated primarily in the prostate, scalp, and hair follicles. This binding reduces DHT concentrations by up to 70 % in serum and up to 90 % in target tissues, leading to decreased androgenic stimulation. In the prostate, lower DHT translates into reduced glandular growth and alleviation of urinary obstruction. In hair follicles, the diminished androgen signal halts the miniaturisation process that drives pattern baldness, allowing existing hairs to thicken and new hairs to emerge.

Both branded (Proscar, Propecia) and generic tablets are stocked by our pharmacy service, providing cost-effective access without compromising quality.

How Finasteride Works

Mechanism of Action

Finasteride is a reversible, competitive inhibitor of the type II 5-alpha-reductase enzyme. By occupying the enzyme’s active site, it prevents the reduction of testosterone (T) to dihydrotestosterone (DHT). The resulting drop in DHT levels diminishes androgen-driven signalling pathways in the prostate and scalp. This biochemical blockade is the foundation of the finasteride mechanism of action that physicians rely on for both BPH and hair-loss therapy.

Therapeutic Effects

The decline in DHT produces two clinically meaningful outcomes. In the prostate, reduced DHT leads to a gradual decrease in gland volume, relieving lower-urinary-tract symptoms such as nocturia, weak stream, and incomplete bladder emptying. In hair follicles, the lower androgenic pressure slows the transition of thick, terminal hairs to fine, vellus-like hairs, thereby stabilising hair loss and promoting regrowth over time.

Onset and Duration

Clinical trials indicate that urinary symptom improvement becomes noticeable after approximately six weeks of daily 5 mg dosing, with maximal benefit usually reached by six months. For hair loss, patients typically report the first visible signs of regrowth after three to six months of a 1 mg daily regimen, and continued use maintains the benefit. Finasteride’s half-life is about six to eight hours, but its downstream effect on DHT persists for several days, allowing once-daily dosing.

Approved Uses and Applications

Approved Indications

• Benign Prostatic Hyperplasia (BPH): The 5 mg tablet is approved by the TGA, FDA, and EMA for men with symptomatic prostate enlargement. It reduces prostate size, improves urinary flow, and lowers the risk of acute urinary retention.
• Androgenetic Alopecia (Male Pattern Hair Loss): The 1 mg tablet is approved for men aged 18 years and older with mild to moderate vertex or crown hair thinning. Clinical data from the New England Journal of Medicine demonstrated a 66 % reduction in hair loss progression after 12 months of treatment.

Off-Label Uses

Finasteride is occasionally prescribed off-label for chronic prostatitis, hirsutism in women (under strict supervision), and as an adjunct in hormone-sensitive prostate cancer management. These applications are not officially sanctioned by regulatory agencies, and patients should discuss the evidence and risks with their clinician.

Clinical Efficacy

• BPH: A pivotal Phase III trial published in The Lancet showed a 30 % reduction in International Prostate Symptom Score (IPSS) after six months of 5 mg finasteride versus placebo.
• Hair Loss: A double-blind study in JAMA Dermatology reported that 48 % of men treated with 1 mg finasteride experienced a ≥20 % increase in hair count at 12 months, compared with 12 % in the placebo group.

Dosing, Formulations & Administration

Available Formulations

Finasteride is marketed as oral tablets in two strengths: 1 mg (hair loss) and 5 mg (BPH). Some regions also offer a .5 mg tablet for dose-adjustment, though it is less common in Australia.

Typical Dosing Ranges

• BPH: Clinicians often start adults on 5 mg once daily; dose may be maintained indefinitely, provided symptom control and tolerance.
• Androgenetic Alopecia: The usual regimen is 1 mg taken once daily. Some dermatologists may advise intermittent dosing after the first year to assess maintenance needs.

These examples reflect standard practice; individual dosing must be determined by a qualified healthcare provider who considers disease severity, comorbidities, and concomitant medications.

Administration Guidelines

Finasteride tablets can be swallowed with or without food; food does not significantly affect absorption. Consistency in timing-morning or evening-helps maintain steady plasma levels. Patients should avoid crushing or splitting tablets, especially women of child-bearing potential, because even trace amounts of finasteride can cause fetal abnormalities.

Remember: A healthcare professional must tailor the exact dose and schedule to each patient’s unique clinical picture.

Safety Profile & Considerations

Common Side Effects

• Decreased libido: Reported in 10-15 % of men during the first year of therapy.
• Erectile dysfunction: Occurs in roughly 5-7 % of users.
• Ejaculatory disorder (reduced volume): Seen in 3-5 % of participants.
• Breast tenderness or enlargement: Documented in <2 % of cases.
• Rash or pruritus: Less than 1 % incidence.

These effects are generally mild and often resolve with continued treatment or dose adjustment.

Serious Adverse Events

• High-grade prostate cancer: Meta-analyses suggest a modest increase in the incidence of aggressive prostate cancer after long-term use; routine PSA monitoring is recommended.
• Male breast cancer: Extremely rare (<0.1 %) but documented; any breast changes warrant immediate evaluation.
• Severe allergic reaction (anaphylaxis): Rare, presenting with rash, swelling, and respiratory distress.

Patients experiencing any of these serious symptoms should seek urgent medical care.

Contraindications

Finasteride is contraindicated in women who are pregnant or may become pregnant, as the drug can cause birth defects related to male genital development. It is also contraindicated in individuals with known hypersensitivity to finasteride or any tablet excipients.

Drug Interactions

• CYP3A4 inhibitors (e.g., ketoconazole, erythromycin): May increase finasteride plasma concentrations; dose adjustment may be required.
• Other 5-alpha-reductase inhibitors (e.g., dutasteride): Concurrent use provides no additional benefit and raises risk of side effects.
• Testosterone therapy: May counteract finasteride’s effects on DHT; clinicians should monitor hormone levels closely.

Special Populations

• Pregnancy & Breastfeeding: Women should avoid handling crushed or broken tablets; finasteride is not indicated for lactating mothers.
• Older Adults: No dosage reduction is mandated, but clinicians should assess renal and hepatic function annually.
• Hepatic Impairment: Mild to moderate liver disease does not require dose change, but severe impairment may warrant caution.

Overall, the safety profile of finasteride is favourable when used under professional supervision, with routine laboratory monitoring as recommended.

Frequently Asked Questions

• What is the difference between finasteride and dutasteride? Finasteride selectively inhibits the type II isoform of 5-alpha-reductase, while dutasteride blocks both type I and type II enzymes, leading to a greater overall reduction in DHT. This broader inhibition can produce slightly higher efficacy for BPH but may also increase the risk of side effects.

• How long does finasteride take to work for hair loss? Most men notice the first signs of hair regrowth after three to six months of daily 1 mg dosing. Full therapeutic effect typically stabilises around the 12-month mark, provided the medication is continued.

• Can I buy finasteride online without a prescription? Our online pharmacy requires a valid prescription from a licensed Australian practitioner, ensuring safe and legal access while complying with TGA regulations.

• What should I do if I experience decreased libido while using finasteride? Discuss the symptom with your healthcare provider; they may adjust the dose, suggest a temporary drug holiday, or explore alternative therapies. Abrupt discontinuation without advice is discouraged, as withdrawal can affect hormone balance.

• Are there foods I should avoid while taking finasteride? No specific dietary restrictions are necessary. However, consistent intake of high-fat meals does not significantly affect absorption, so you may take the tablet with or without food based on personal preference.

• Is finasteride safe for long-term use? Long-term studies up to ten years demonstrate sustained efficacy for BPH and hair loss with a stable safety profile. Ongoing PSA monitoring is advised to detect any potential changes in prostate health.

• Can finasteride cause breast enlargement in men? Gynecomastia is a rare side effect, occurring in less than 2 % of users. If you notice breast swelling or tenderness, contact your clinician promptly.

• Will finasteride interact with over-the-counter supplements? Certain herbal supplements, such as saw palmetto, also inhibit 5-alpha-reductase and could theoretically augment finasteride’s effect, potentially increasing side-effect risk. Discuss any supplement use with your provider before combining them.

• What information should I provide my doctor when discussing finasteride?

  • Complete list of current prescription and over-the-counter medications, including supplements.
  • History of prostate or hormonal conditions, and any previous treatments.
  • Specific symptoms you aim to treat (e.g., urinary obstruction, hair thinning).
  • Any known allergies or prior adverse reactions to similar drugs.
