Be very , very careful of Adovart Dusteride. My husband was recommended this drug by a top surgeon here, who said there were no side effects. He hardly slept for 2 years, we could not figure out why. I looked into and found many forums complaining about this drug. Side effects not sleeping and feeling very weak. The day he stopped this drug , he slept 14 hrs straight through , it took 6 months to get this drug out of his system He know takes Saw Palmetto, one capsule a day, extra strength , Havasu. His enlarged prostate is fine and so is his PSA level.
