A Patient's Guide to Propecia: Uses, Dosing, Cost, and Adverse Effects - in Australia

Big picture summary and expectations

Finasteride is the active ingredient found in brands such as Propecia and in many generic preparations. It is a 5-alpha-reductase inhibitor used primarily for male pattern hair loss (androgenetic alopecia) at low doses and at higher doses for treatment of benign prostatic hyperplasia (BPH).

Common tablet strengths sold include 1 mg, typically prescribed for scalp hair loss, and 5 mg, which is the usual formulation for prostate enlargement. Clinical studies and routine clinical use show that many men experience increased hair density at the crown and slowed progression at the front. Noticeable improvements often require daily use for a minimum of three to six months, and benefits are mostly maintained only while treatment continues.

• Liver impairment: use with caution in significant hepatic impairment; performance monitoring may be recommended.
• Blood donation: avoid donating blood while taking finasteride and for at least one month after stopping to avoid exposing a pregnant transfusion recipient.
• Driving and machinery: some patients report dizziness or visual disturbance. If these occur, avoid driving or operating machinery until recovered.
