Can i take Butalbital-APAP-Caffeine and hydrocodone few hours later?

I assume your hydrocodone is also in a compound with APAP (acetaminophen, tylenol) as well, so you should watch your total tylenol intake (single dose max 1000mg; 24hr max 4000mg), but there is no official interaction listed, so you should be fine. They can both cause some drowsiness in some people and that effect may be compounded by concurrent use, but 6 hours should be plenty of time for the effects of the butallbital to have subsided. Still take it easy, don't go driving your bulldozer around the neighborhood as well as operating other heavy machinery until you're sure you have your land legs and you'll be fine.
