I was Norwood Class I and Took Propecia for 8 Years. Can I Stop Taking it To Have A Baby?

Hi Dr – Firstly just wanted to say thank you for the wonderful work you are doing on this site!

I took Propecia 1mg for 8 years, but a couple of years ago I noticed I was losing ground (NW1 – NW3). I increased my Propecia dosage to 2mg and have been taking this for the past 2 years and experienced no side effects.

I am 34 years old now and thinking of starting a family. My question is: Is it safe to be on 2mg Propecia a day and trying for a baby? If I completely stopped Propecia now, how long will it take for the drug to be completely out of my system? I really worry that, so much Finasteride will pose a risk to my unborn child? I will be discussing this with my doctor, but you are a specialist in this field and would really appreciate some advice.

First and foremost, please follow up with your doctor and address your question to him/her.

I have some issues with your history and you need to follow your doctors recommendation. If you are a Norwood 1 or even 3, I question if you should have been on Propecia. Propecia does not work to prevent a mature hairline from forming. Propecia is meant for the frontal area, the top and the crown areas. It is sometimes taken in hopes that it will help with the frontal corners but that decision is up to you and your doctor. At least you didn’t have any side effects and you seem to have done well. Another issue is that higher dose of Propecia doesn’t really work any better than the 1mg dose.

Finally, Propecia does not affect conceiving or having a baby. There is no evidence of this. For those who are still worried about it, Propecia has a half life of about 4 hours in the blood stream. This means almost all the medication will be out of your blood stream in 1 day. With respect to tissue fixation and possible traces left in your body it can take between 1 to 2 weeks. Considering the thousands of men who may have fathered children while on the drug, to my knowledge there has been no medical issues or legal issues.
