My Husband Was Prescribed Tylenol/cod3 And Diazepam For Pain Management

My husband was prescribed Tylenol/cod3 and diazepam for pain management after hemmoroidectomy surgery. We were not told if these drugs should be taken simultaneously or to alternate them. Tylenol says it can be taken every 4 hrs. , diazepam every 6. He was also prescriben melódicamente, once daily.


Thank you
