[gottaheadache]

I have a white oval pill/large that has the number 93-490. I was told it was Darvocet, but i'm not sure. I was given this for my bad headaches from a friend, so I didn't see the bottle. Can anyone help?
Thanks!

Generic Name: Propoxyphene-N w/ APAP Tab 100-650 MG. (Teva Pharmaceuticals)

This appears to be Teva's generic version of the original Darvocet-N 100 (aaiPharma Inc.).

Both of these contain 100 mg of propoxyphene napsylate to 650 mg of acetaminophen.

However, I read that aaiPharma in 2003 introduced an alternative Darvocet formulation with lower acetaminophen content (100/500). This is called Darvocet A500, which, "taken at the daily dose, provides 1,000 mg less acetaminophen than the FDA limit...reduces the likelihood of exceeding the recommended daily limit for acetaminophen when taken up to six times per day, without sacrificing analgesic efficacy."
