Finasteride

Drug Details

Finasteride is a medication prescribed for different purposes depending on its dosage. At a 5 mg dosage, it is used to treat benign prostatic hyperplasia (BPH) in adult men by reducing prostate size. This helps alleviate symptoms such as frequent urination, difficulty in starting urination, and the sensation of incomplete bladder emptying. It works by decreasing levels of dihydrotestosterone (DHT), a hormone responsible for prostate growth. Although effective in managing BPH symptoms, finasteride is not approved for prostate cancer prevention and may slightly increase the risk of developing a serious form of prostate cancer. Women and children should not use this medication. In a 1 mg dosage, finasteride, sold under the brand name Propecia, is used to treat male pattern baldness (androgenetic alopecia) in adults. This formulation works by inhibiting the enzyme 5-alpha reductase, which converts testosterone to DHT. By lowering DHT levels in the scalp, it helps reduce hair loss and promotes hair growth. Finasteride is taken orally once a day and requires a prescription. Potential side effects include sexual dysfunction, such as reduced libido and erectile issues. Always consult with a healthcare provider to understand the benefits and risks before starting finasteride.
