Other Comments

The FDA has asked manufacturers to limit the maximum amount of acetaminophen in prescription products to 325 mg per dosage unit. There are no data that indicate that taking more than 325 mg of acetaminophen per dosage unit provides more pain relief. The goal of the FDA is to reduce the risk of severe liver injury from acetaminophen overdose, which can lead to liver failure, liver transplant, and even death. The total number of units that may be prescribed and the time intervals for dosing will not change. Drug companies will have until January 14, 2014 to comply with FDA requirements.
