Dutasteride is a medication primarily used to treat benign prostatic hyperplasia (BPH), a condition where the prostate gland becomes enlarged, causing urinary problems in men. It works by inhibiting the action of certain hormones that contribute to prostate growth, helping to reduce symptoms and improve urinary flow. In addition to BPH, Dutasteride is sometimes prescribed for male pattern baldness. By blocking the conversion of testosterone to dihydrotestosterone (DHT), it can help slow hair loss and promote regrowth. However, like all medications, it may have side effects, so it's important to discuss its use with a healthcare provider.
