I'm using topical finasteride 0.1% solution for more than 1 yr.wil it cause impotent for using another 1 yr nd how long can i take it with minimal se?

Who know?: The available clinical information indicated topical Finasteride has the same effect to suppress dht; that's understandable, but the pace &degree are less than oral. As to how often and how long ti may be, no confirming data is around to tell; but one thing for sure is very low (.

See answer: Topical Finasteride 0.1% is approximately equal to 1mg Finasteride orally which is the dose of propecia (finasteride). In 3 controlled clinical trials for Propecia (finasteride) of 12-month duration involving 945 patients, 1.8% reported decreased libido and 1.2-1.3% reported ed or reduction in ejaculation volume. These numbers were only slightly greater than placebo. These numbers likely do not change much with long-term use.
