Will darvocet affect blood thinning?

Removed for market. I believe darvocet has been removed from the market. Otherwise, it is a combo drug including Acetaminophen (ie tylenol). Not aware of any overwhelming link of this combo to blood thinning. What else are you taking that may cause this and how do you know your blood is "thinning"?
Darvocet. Do you take a blood thinner? None of the common side effects for this medication state that; and it does not appear to interact with blood thinners.
