Keep an eye on any prescription painkillers you receive after today’s date. You should see brand and generic Vicodin, Percocet and other narcotics will have 300mg of Tylenol instead of 500mg, 650 mg, or 750mg per pill previously.
This is an FDA mandate imposed on acetaminophen content because of the liver damage and death associated with more than 4,000mg per day. Many patients were unknowingly exceeding 4,000mg per day by using a prescription painkiller coupled with an over-the-counter pain reliever or cold medicine that contained Tylenol.
FDA reports the lessening of acetaminophen in these narcotic pain relievers only marginally affects efficacy of pain relief since the narcotic content is not changing. Acetaminophen acts to potentiate the effects of the narcotic ingredient. Acetaminophen is also legally required — or some secondary ingredient to the narcotic such as ibuprofen or aspirin — in order to help curb the abuse potential.
