There is no official change from the FDA as of yet, but there are many advisories against long term use of APAP over 3g/day. More specifically, APAP in combination with other pain relievers (oxycodone/hydrocodone) are being limited to a max of 325mg per pill in the fairly near future pursuant to a strong request from the DEA to drug manufactures. Abbott is poised to capitalize on this as it has reformulated its branded Vicodin to 5/300mg They are expecting patients to be stupid and pharmacists/doctors to be lazy, hence, if a doctor writes Vicodin on a script, a pharmacist technically will have to call the prescriber to get it changed to the 5/325 strength product that is less expensive.
