About Proscar
Proscar (5 mg finasteride tablets) is a prescription-only medication approved in Australia for the treatment of benign prostatic hyperplasia (BPH). As a selective 5α-reductase inhibitor, it reduces the conversion of testosterone to dihydrotestosterone (DHT), helping to shrink an enlarged prostate and improve urinary flow. While its primary indication is BPH, clinicians sometimes discuss finasteride for other male-health concerns such as androgenetic alopecia, though those uses are not approved by the Therapeutic Goods Administration (TGA). Understanding how Proscar works, when it is appropriate, and how to manage its effects can empower men to make informed decisions about their health.
What is Proscar?
Proscar is the brand name for a 5 mg tablet of finasteride, classified as a 5α-reductase inhibitor. The product received TGA approval in 1995 and is marketed in Australia by Merck Sharp & Dohme (MSD). It is available only with a prescription and is listed on the Pharmaceutical Benefits Scheme (PBS) for eligible patients with symptomatic BPH. As a brand-name product, Proscar is chemically identical to generic finasteride but carries MSD’s branding and packaging.
How Proscar Works
Finasteride selectively blocks the type II isoenzyme of 5α-reductase, the enzyme responsible for converting testosterone into the more potent androgen DHT. In the prostate gland, DHT drives cellular proliferation, leading to gland enlargement. By lowering intraprostatic DHT levels by up to 70 %, finasteride gradually reduces prostate volume, typically by 20-30 % over six months.
Pharmacokinetic data show that finasteride is well absorbed after oral ingestion, reaching peak plasma concentrations within 1-2 hours. The drug is about 90 % bound to plasma proteins and is metabolised primarily in the liver via CYP3A4, producing inactive metabolites that are excreted in the urine (≈ 70 %) and feces (≈ 30 %). The terminal half-life is roughly 5-6 hours, allowing once-daily dosing without the need for therapeutic drug monitoring.
Why Proscar is Used for Men’s Health Conditions
-
Benign Prostatic Hyperplasia (BPH) - The reduction in DHT directly lessens prostatic stromal and epithelial growth, leading to smaller gland size and reduced urethral compression. Clinical trials show a 30-40 % improvement in International Prostate Symptom Score (IPSS) after six months, making it a first-line oral therapy in Australian urology guidelines.
-
Prevention of Acute Urinary Retention - By decreasing prostate volume, Proscar lowers the risk of sudden urinary blockage, a common complication in men with moderate to severe BPH.
-
Adjunct to Surgical Management - In men undergoing transurethral resection of the prostate (TURP), pre-operative finasteride can diminish intra-operative bleeding by reducing vascularisation driven by DHT.
-
Potential Role in Lower-Grade Prostate Cancer - Long-term studies have observed a modest reduction in the incidence of low-grade prostate cancer among men on finasteride, though the drug is not approved for cancer prophylaxis in Australia.
Off-Label and Investigational Uses of Proscar
Although not approved by the TGA for hair loss, finasteride 5 mg has been investigated for androgenetic alopecia in men. Randomised controlled trials demonstrate increased hair count and density after 12 months of therapy, but higher doses are associated with a greater incidence of sexual side effects.
Research is also exploring finasteride’s effect on chronic prostatitis/chronic pelvic pain syndrome, with small pilot studies suggesting symptom relief in a subset of patients.
Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Proscar Right for You?
Men who experience frequent nighttime urination, weak stream, or a sensation of incomplete bladder emptying often benefit from Proscar, especially when prostate volume exceeds 30 mL on imaging. The medication is generally well tolerated in older adults, but clinicians may adjust expectations for those with hepatic impairment, as metabolism slows. Women and children are excluded from treatment because finasteride can cause birth-defect risks if a pregnant woman is exposed to crushed tablets.
Patients with a history of prostate cancer, severe liver disease, or allergic reactions to finasteride should discuss alternatives with their physician. For men planning to conceive, discontinuation is advised, as the drug can affect sperm parameters.
Taking Proscar Effectively
- Timing - Take the tablet at the same time each day, with or without food; food does not significantly alter absorption.
- Missed Dose - If a dose is forgotten within 12 hours, take it as soon as remembered. Skip it if it is almost time for the next dose to avoid double-dosing.
- Travel - Pack tablets in the original labeled container, and keep them out of extreme heat. No special storage beyond a cool, dry place is required.
- Drug Interactions - Strong CYP3A4 inhibitors (e.g., ketoconazole) can increase finasteride plasma levels modestly; dose adjustment is rarely needed but clinicians should be aware.
Adhering to a consistent daily routine maximises prostate volume reduction and symptom improvement.
Understanding Side Effects and How to Manage Them
Finasteride’s side-effect profile reflects its hormonal influence.
- Sexual Dysfunction - Decreased libido, erectile difficulty, and reduced ejaculate volume occur in 1-10 % of users. These effects often resolve after discontinuation, but some men report persistence. If symptoms arise, discuss dose reduction or a trial discontinuation with a physician.
- Breast Tenderness or Enlargement - Hormonal shifts can cause gynecomastia in a small proportion of patients. Monitoring breast tissue and reporting any changes promptly is advisable.
- Psychological Effects - Mood swings and depressive symptoms have been reported; any emerging mental health concerns should trigger an immediate medical review.
- Allergic Reactions - Rash or urticaria may indicate hypersensitivity; discontinue use and seek urgent care if swelling or breathing difficulty develops.
Most adverse events are mild and transient. Patients should keep a symptom diary and contact their clinician if side effects interfere with daily life.

Frequently Asked Questions
-
What is the typical time to notice improvement in urinary symptoms? Most men report a noticeable reduction in frequency and urgency after 4-6 weeks, with maximal benefit occurring around 6 months of continuous use.
-
Can I take Proscar with other BPH medications? Finasteride is often combined with alpha-blockers (e.g., tamsulosin) to provide both rapid symptom relief and long-term prostate shrinkage; your physician will tailor the regimen.
-
Will Proscar affect my PSA test results? Finasteride lowers serum prostate-specific antigen (PSA) by about 50 %, so doctors adjust PSA values accordingly when monitoring for prostate cancer.
-
Is it safe to use Proscar if I have mild liver disease? Because the drug is metabolised hepatically, dose adjustment is not routinely required for mild impairment, but severe liver dysfunction warrants caution and close monitoring.
-
How does Proscar differ from the 1 mg finasteride tablets used for hair loss? Both contain the same active molecule; the 5 mg dose provides a stronger DHT suppression needed for prostate tissue, while the 1 mg dose is sufficient for scalp hair follicles and carries a lower risk of systemic side effects.
-
Can I stop Proscar abruptly if I no longer need it? Yes, discontinuation does not require tapering. However, prostate size may gradually return to baseline over several months, potentially reinstating urinary symptoms.
-
Does Proscar interact with over-the-counter supplements? Herbs that affect hormone metabolism, such as saw-palmetto, may have additive effects on DHT. Discuss any supplement use with your pharmacist to avoid unintended hormonal shifts.
-
Is finasteride safe for men planning to father a child? While most studies show no significant impact on fertility, a minority experience reduced sperm count. Men attempting conception should discuss the risk-benefit balance with their doctor.
-
What should I do if I miss a dose for more than 24 hours? Resume the regular once-daily schedule; there is no need for a loading dose, but consistent use is key for therapeutic effect.
-
Are there any dietary restrictions while taking Proscar? No specific foods interfere with absorption, but excessive alcohol may worsen liver function, indirectly affecting drug metabolism.
