Male, is finasteride lost through urinating?

Finasteride, like many other medications, is metabolized in the liver and then excreted from the body through urine and feces. However, it's important to note that the drug doesn't simply pass through the body unchanged. It is broken down in the liver into its metabolites, which are then eliminated. This process means that the drug has had a chance to circulate in the body and have its intended effect. So, while finasteride does eventually leave the body through excretion, it's not "lost" in the sense that it's wasted or doesn't have an effect.

Thank you for the excellent question. Finasteride is first broken down by the liver into what we call metabolites. The metabolites have less than 20% of the activity of finasteride and exit the body via the feces (57%) and the urine (39%). So to answer your question, yes, a portion of finasteride exits the body through urine. But it's not the process of urinating that stops the action of finasteride though. The majority of the function of finasteride is stopped when the liver breaks it down.

Hello and thank you for your question. Yes, eventually Finasteride is excreted through urine and feces. First, it is metabolized through the liver then. This does not mean that it goes straight through your body, it does what it's meant to do and then is eliminated.

Metabolites of finasteride are eliminated via both feces and urine. So, yes, some of the finasteride (following extensive metabolism in the liver) is eliminated through urine.
