community Finasteride affects both 5a reductase and 5b reductase

6 upvotes 5 years ago

Finasteride not only inactivates the 5a reductase enzyme but also affects the 5b reductase enzyme in a dose-dependent manner, which can impact sexual behavior and brain activity. The user experienced significant hair regrowth and side effects on 1mg of finasteride, which diminished after reducing the dose to 0.5mg, leading to no side effects and further hair improvement.

community From the research study: "Dihydrotestosterone and the concept of 5a-reductase inhibition in human benign prostatic hyperplasia" - G. Bartsch, R.S. Rittmaster, H. Klocker (2002) in the "World Journal of Urology".

in Research/Science 23 upvotes 2 years ago

Dutasteride is a stronger 5AR inhibitor than finasteride and can significantly lower DHT levels. Reduced doses of dutasteride may lower side effects.

community A repository of links to current scientific research and findings into the nature of and relating to side-effects for Finasteride/Dutasteride/5a-reductase inhibitors.

in Finasteride 17 upvotes 5 years ago

Finasteride and dutasteride, used for hair loss, can cause sexual dysfunction, depression, and suicidal thoughts, with some effects persisting after stopping. The post stresses the importance of being aware of these risks.
