Finasteride is a medication primarily used to treat conditions related to excessive production of the hormone dihydrotestosterone (DHT). Its applications and effects vary depending on the dosage and condition being treated.Finasteride is a medication primarily used to treat two conditions:
1. Androgenetic Alopecia (Male Pattern Baldness):
- How it works: Finasteride inhibits the enzyme 5-alpha reductase, which converts testosterone to dihydrotestosterone (DHT). DHT is a hormone that contributes to hair follicle shrinkage, causing hair loss.
- Dosage: Typically prescribed at 1 mg daily for hair loss.
- Effectiveness: It may take 3–6 months of consistent use to notice results, with the maximum effect seen after a year. Continued use is necessary to maintain hair regrowth or prevent further loss.
- Common brand names: Propecia.
2. Benign Prostatic Hyperplasia (BPH):
- How it works: By reducing DHT levels, Finasteride can shrink the prostate gland, improving urinary symptoms associated with BPH.
- Dosage: Usually prescribed at 5 mg daily for BPH.
- Effectiveness: It may take several months to see significant improvements in symptoms.
- Common brand names: Proscar.
