Finasteride – Uses, Side Effects & Practical Tips

When you hear the name Finasteride, a prescription drug that blocks the hormone conversion that leads to hair loss and prostate growth, also known as Propecia or Proscar, you might wonder what it actually does. In simple terms, finasteride is a 5-alpha-reductase inhibitor, meaning it stops the enzyme that turns testosterone into dihydrotestosterone (DHT). Lower DHT levels help keep hair follicles from shrinking and shrink the enlarged prostate tissue that causes urinary problems. This drug therefore sits at the crossroads of two common health concerns: androgenetic alopecia (pattern hair loss) and benign prostatic hyperplasia (BPH). The triple relationship can be summed up as: Finasteride treats hair loss, Finasteride treats BPH, and both effects stem from its action on the 5‑alpha‑reductase enzyme.

Why does this matter for everyday readers? If you’re watching the hair on your pillow or dealing with frequent trips to the bathroom, the underlying cause is often excess DHT. Men and even some women with a genetic tendency to produce too much DHT can see hair thinning in the crown or a slowly expanding prostate. Finasteride offers a targeted approach: a daily tablet that cuts DHT production by about 70 % in the scalp and about 50 % in the prostate. The result is a noticeable slowdown in hair loss after three to six months and a reduction in urinary symptoms within a similar timeframe. Of course, no medication is free of downsides. Common side effects include reduced libido, mild erectile issues, and occasional mood changes. These are tied to the same hormonal pathway, so they tend to appear when DHT drops sharply. Most users find the benefits outweigh the risks, especially when the drug is monitored by a doctor who can adjust the dose or switch to alternative therapies if needed.

What to Expect When Starting Finasteride

Starting finasteride is usually a straightforward process: get a prescription, take the pill at the same time each day, and keep an eye on any changes. Within the first month, many people notice a “shedding” phase where old hairs fall out to make way for new growth—this is normal and signals the drug is working. Labs may be ordered to check prostate‑specific antigen (PSA) levels because finasteride can lower PSA, which is a key marker doctors use for prostate cancer screening. If you’re on the BPH dose (5 mg), your doctor will track urinary flow rates and bladder emptying. For the hair‑loss dose (1 mg), follow‑up usually involves photographs or scalp exams to gauge progress.
