Propecia and Vitamin K

[Follically Challenged]

Recently I've been taking vitamin K supplements and had put the pills in a pill holder with my propecia.

The propecia and the vitamin K reacted with each other. In the "boxes" where there was only Propecia, no reaction.

So i would recommend not taking Propecia at teh same time as taking vitamin K, if anyone here ever plans on taking vitamin K supplements.
