Finasteride is a 5α-reductase inhibitor. This means it blocks the enzyme that converts testosterone into dihydrotestosterone (DHT). High DHT levels are linked to male pattern baldness.
Propecia contains 1mg of finasteride. This lower dosage is specifically formulated for hair loss treatment. Higher dosages are used to treat benign prostatic hyperplasia (BPH).
Taking finasteride daily can help slow or even reverse hair loss in many men. Results aren’t immediate; you may see improvements after three months, with optimal results often taking longer.
Side effects are possible, though not everyone experiences them. Common side effects include decreased libido, erectile dysfunction, and ejaculation problems. These are usually mild and temporary, but discontinuation may be necessary if bothersome.
Before starting finasteride, discuss potential risks and benefits with your doctor. They can assess your suitability for the medication and monitor your progress.
