I have frequently taken Hydrocodone, Oxycodone, etc. in either 5 or 10 mg strengths for codeine. Looking at the prescription I just had filled it is 300mg acetaminophen and '30 mg' codeine. Can this be right? Is there something I don't know? Is it really that much stronger? Should I be concerned? Should I not take them until I can talk to my pharmacist or Dr.?
