I am 39 years old from Hyderabad. I am hale and hearty. I have allergic bronchitis, but currently on no medications. I have only one major problem that I have androgenic alopecia in the center of the head from back. Long back in 2001 I used Minoxidil. Did not observe whether it helped or not. Recently I have heard about Finasteride (Works on Type 2) and Dutasteride (Works on Type 1 & 2), a inhibitor of 5?-reductase enzyme which inhibits converting excess testosterone to dihydrotestosterone) which is primarily treated for BPH & secondarily treated for Hair Loss. I have done enough research on this. I do not know whether I have prostate enlargement or not. No pain surrounding pubic area, but when I do flatus sometime little drops of urine come when bladder is full. I have also read about its sexual side effects and its half life (traces in blood for nearly 6 mths even after stopping). I firmly believe that anything overdose leads to its side effects. Can I use this drug? I am planning to use 0.5 mg every five days so that it will be 0.1 mg every day. If I can use how long should I use?
