Fioricet 50/325/40 for migraines,knee surgery 40days ago,still norco (hydrocodone and acetaminophen) 1-10/325 before pt. can i take them together if need to, with 1-2 hrs.apart)?

Yes, you can : However, may increase side effects such as dizziness, drowsiness, and difficulty concentrating. Always take these medications on a schedule as directed by your doctor.

Sorry, this is more than a nasty combination, it is dangerous, and the frequency is actually life threatening. Both can depress the central nervous system, prompting potential apnea, especially while sleeping. These drugs are best separated by at least 6-8 hrs, and should NEVER be ingested together.
