What are the possible negative consequences of accidentally double dosing Propecia? Taking Propecia every morning has been part of my morning routine for about a year now. The other day, I’m about to leave for work and blanked out on weather I had taken my Propecia pill before I got in the shower (my usual pattern), and so I took what might have been a second pill in one morning. Should I be worried, can I ruin the effectiveness of the drug that way? I’m a 30-year old male, been on propecia since May 2009.
Taking a double dose of Propecia will not harm you or your hair and you should not be worried. There are no negative consequences. For that matter missing one dose would not harm you or your hair either. We are all human and we make mistakes.
Also remember that many men take 5x the Propecia dose everyday for certain prostate problems with only a slight increase in side effects. In fact, research has shown that 5x the dose of Propecia prevents certain types of prostate cancer…. but taking more will not make your hair grow better (in case you were going to ask).
