Finasteride: Uses, Effects, and What You Need to Know

When working with Finasteride, a prescription 5‑alpha‑reductase inhibitor that lowers dihydrotestosterone (DHT) levels. Also known as Propecia, it is used both for benign prostatic hyperplasia (BPH) and for male pattern baldness, the drug fits into a broader hormonal management picture. Finasteride blocks the enzyme that converts testosterone into DHT, which is the main driver of prostate enlargement and hair‑follicle mini‑miniaturisation. This simple mechanism creates a direct link: lower DHT → smaller prostate and slower hair loss. Because of that, doctors often prescribe it as a long‑term solution when other therapies fall short.

Understanding benign prostatic hyperplasia, a non‑cancerous growth of the prostate that can cause urinary symptoms helps you see why Finasteride matters for men over 50. At the same time, male pattern baldness, the most common form of hair loss in men, is driven by DHT’s effect on scalp follicles. The hormone dihydrotestosterone (DHT), a potent androgen produced from testosterone is the common thread linking these two conditions. When you lower DHT with a 5‑alpha‑reductase inhibitor, you simultaneously address prostate swelling and hair‑follicle shrinkage. This dual benefit makes Finasteride a unique option compared with treatments that target only one of the issues.

Practical considerations round out the picture. Finasteride requires a prescription, and doctors typically start with a 1 mg daily dose for hair loss or 5 mg for BPH. Monitoring is essential: liver function tests, PSA levels, and sexual side‑effects should be checked regularly. Many patients report initial mild sexual changes that often improve over time, while a small percentage experience persistent issues. Knowing the risk‑benefit balance lets you discuss expectations with your clinician and decide if the drug fits your health goals.
