What is finasteride used for?
Finasteride is a prescription medicine used to treat:
- Benign prostatic hyperplasia (BPH), which is an enlarged prostate that can cause urinary symptoms.
- Male pattern hair loss (androgenetic alopecia).
How does finasteride work?
Finasteride blocks the enzyme 5-alpha-reductase, which helps convert testosterone into dihydrotestosterone (DHT). Lowering DHT reduces the hormone’s effects that drive prostate enlargement and hair loss patterns.
What forms and doses does finasteride come in?
Finasteride is sold in tablet form in different strengths depending on the indication, with BPH and hair-loss dosing typically being different. If you tell me your exact product strength (mg) and what it’s prescribed for, I can help interpret it.
What side effects do people report with finasteride?
Commonly reported side effects include sexual side effects (such as reduced libido and erectile or ejaculation changes). Some people also report breast tenderness or enlargement. As with most prescription medicines, rare but serious reactions can occur.
Can finasteride affect fertility or sexual function?
Because finasteride changes DHT and related androgen signaling, sexual side effects are the main concern patients ask about. If you’re using finasteride and have symptoms, it’s important to discuss dose changes or switching options with a clinician.
Who should not take finasteride (or should use extra caution)?
Finasteride is generally not used for people outside the approved patient populations for its indications. Pregnancy is a key safety issue because finasteride can affect fetal development in a male fetus. People who are or may be pregnant should avoid handling crushed or broken tablets.
How long does it take to see results?
For BPH symptoms, improvement may take weeks and tends to be assessed over time. For hair loss, visible changes typically take months. If you share your start date and dose, I can map what timelines are typical for your situation.
What are alternatives to finasteride?
Depending on whether the goal is prostate symptom relief or hair loss, alternatives can include other medication classes and procedures. Hair-loss alternatives may include topical options or other systemic drugs; BPH alternatives include other prostate-focused medications. The best option depends on your age, symptoms, and risk profile.
