Can you take amoxicillin with Darvocet?

Yes, but you need to be careful and aware that the combination of any painkiller with an antibiotic may make you drowsier than normal. Of course it all depends on your dependence/tolerance level of Darvocet dosage that you're taking. If you've been taking it for some time, then it might not be as bad. Still, you might want to consider taking it before you go to sleep depending on how drowsy it makes you feel.

Also be sure to take it with a lot of water. Depending on how much Darvocet affects your stomach, any antibiotic will normally make you queasy as well, so dilute it as much as possible by drinking a good bit of water with it when you take it.
