Propecia and Coffee

I had a casual conversation with a dermatologist recently, who suggested that taking Propecia in the morning might not be the best idea given I drink around 4 (on rare occasion 5) cups of coffee every morning. The dermatologist said that, generally speaking coffee/tea reduces the absorption effectiveness of finasteride and many other drugs.

Otherwise, he stated that mornings are generally a good time to take medication. He further suggested that 1-2 cups of coffee would be less problematic. Any thoughts on this suggestion?

There are some suggestions I’ve read about on the web that point to some decreased absorption with coffee or alcohol because of the increased frequency of urination… but there’s no certain connection that I know of between drinking coffee and Propecia absorption. You should be fine with the coffee, but grapefruits have been shown to decrease finasteride’s absorption.
