Stopping Propecia While Trying to Conceive a Child

I am trying to conceive with my wife and the doctor advises that I stop taking propecia during this period. If I do so, I have 2 questions:

1. How long after I stop taking it will I start to see hair loss – been on it for 7 years.
2. How long after I stop taking it will my body not have any its system to impact this conception process?

Thanks

Officially, you can continue taking Propecia while trying to conceive a child. From the official Propecia.com’s Possible Side Effects page: “Contact with the semen from a man being treated with PROPECIA is not a risk to the unborn child of a pregnant woman.”

However, some doctors and patients are still cautious about using Propecia when trying to conceive. Because of this, some doctors recommend you temporarily stop taking the medication during the fertile period when you are trying to conceive with your partner and best to stop for only a week when your wife is fertile. You can also stop taking Propecia for two weeks and I doubt it will have any significant negative impact on hair. I’ve written about Propecia and pregnancy before:

• Taking Propecia While Starting a Family
• Taking Propecia While Trying to Have a Baby
