Finasteride – What It Is and Why It Matters

Finasteride is a pill that blocks a hormone called DHT. DHT is the main cause of an enlarged prostate and male‑pattern baldness. By lowering DHT, finasteride can shrink the prostate and keep hair on the scalp.

Common Uses and Dosage

Doctors prescribe finasteride for two main reasons. The first is Benign Prostatic Hyperplasia (BPH), a condition that makes it hard to pee. The usual dose for BPH is 5 mg once a day. The second use is androgenetic alopecia, the technical name for male‑pattern hair loss. For hair loss the dose is 1 mg a day, taken at the same time each day.

It’s a good idea to take the pill with food or without – it doesn’t matter much. What does matter is staying consistent. Skipping doses can cause the prostate to grow back or hair loss to resume.

Potential Side Effects and Precautions

Most people tolerate finasteride well, but a few experience side effects. The most common are reduced libido, trouble getting an erection, and a slight decrease in semen volume. These usually improve after a few weeks or when the dose is lowered.

Less common issues include breast tenderness, rash, and dizziness. If any of these get worse, talk to a doctor right away. Women who are pregnant or may become pregnant should never handle crushed or broken tablets because the drug can affect a male fetus.

Because finasteride changes hormone levels, doctors may order a blood test after a few months to check prostate‑specific antigen (PSA). This helps monitor prostate health and makes sure the medication is doing its job.

When stopping finasteride, expect the benefits to fade gradually. The prostate may enlarge again over several months, and any hair that was saved can start to thin after a few weeks.

People with liver problems need a lower dose because the drug is processed in the liver. If you have liver disease, tell your doctor so they can adjust the prescription.

Finasteride can interact with other medicines that affect hormones, such as certain antifungals or HIV drugs. Always list every medication you take when you start finasteride.

For those worried about sexual side effects, a common tip is to give the body a break after a few months. Some men pause the medication for a short period, but this should only be done under medical supervision.

Overall, finasteride works well for both prostate and hair concerns when taken as directed. Knowing the right dose, watching for side effects, and keeping up with doctor visits will help you get the most benefit.

If you’re thinking about trying finasteride, write down any questions you have and bring them to your appointment. Understanding what the pill does, how long it takes to work, and what to expect can make the decision easier and give you confidence in your treatment plan.
