Can you mix hydrocodone and butalb-acetamin together?

Yes: Yes, but could cause extra sedation and potentially a large dose of acetaminophen. Talk to your doctor. I assume this is for headaches. This combination can cause rebound headaches and more your condition worse.

If prescribed...: If your physician has prescribed them for use together. There can be some sedation and possibly respirtory depression which can result from concomitant use.
