Finasteride – Everything You Need to Know

When you hear Finasteride, a prescription drug that blocks the hormone DHT to treat enlarged prostate and male pattern hair loss. Also known as Proscar or Propecia, it has become a go‑to option for many men facing these issues. Finasteride works by inhibiting the enzyme 5-alpha-reductase, the protein that converts testosterone into dihydrotestosterone (DHT), the hormone largely responsible for prostate growth and follicle miniaturization. Because of that, the drug directly tackles two common male health concerns: benign prostatic hyperplasia, non‑cancerous enlargement of the prostate gland that can cause urinary symptoms and male pattern baldness, a hereditary form of hair loss driven by DHT. Understanding these connections helps you see why doctors often prescribe the same molecule for seemingly different problems.

Key Benefits and Considerations

Finasteride’s impact on prostate size is measurable within a few months; studies show an average reduction of 20‑30% in gland volume, which often eases nighttime frequency and weak stream. For hair loss, a daily 1 mg dose can halt shedding in most users and stimulate new growth in about a third, especially on the crown. It’s important to note that the drug’s effect is dose‑dependent – the 5 mg formulation used for BPH versus the 1 mg version marketed for hair loss illustrate this split. When you compare it to dutasteride, another 5‑alpha‑reductase inhibitor that blocks both type I and type II enzymes, finasteride is generally better tolerated, though dutasteride may achieve slightly stronger DHT suppression. Side‑effects can include reduced libido, mild erectile changes, and occasional mood shifts; they usually improve after a dosage adjustment or a short break. Regular blood tests aren’t required for most users, but checking PSA levels before and during treatment helps track prostate health and flags any rare complications early.

Practical tips can make the experience smoother. Take the pill at the same time each day, with or without food, to keep blood levels steady. If you’re starting a BPH regimen, your doctor may begin with 5 mg and monitor urinary symptoms before deciding on long‑term use. For hair loss, many men pair finasteride with topical minoxidil – the combination often yields better coverage than either alone. Women who are pregnant or may become pregnant should avoid handling crushed or broken tablets because of potential fetal risks. Lastly, remember that stopping finasteride will typically reverse its benefits within a year, so any decision to discontinue should be discussed with a healthcare professional.
