Patients sometimes take drugs that combine acetaminophen and other pain killers after dental procedures, surgeries or injuries. Now the FDA is asking doctors to stop prescribing combination medications that contain more than 325 milligrams of acetaminophen.

"Those doses of acetaminophen, when higher, are one of the most common causes of liver damage in the United States," says Doctor William Cooper. That damage can lead to liver transplants and even death.

Acetaminophen is found in more than 600 medications, including many over the counter products.

Doctor William Cooper, of Vanderbilt University, was on a committee that made some of the recommendations. He says patients often overdose on the drug by mistake. Cooper says, "They'll take it as prescribed but they may not have complete pain relief so they'll take an additional Tylenol product or some other product on top of that."  

In 2011, the FDA asked drug manufacturers to lower the amount of acetaminophen in combination medications. While  many have complied, some higher dose drugs are still on the market.

The FDA is now urging pharmacists to contact doctors if a patient tries to fill a prescription with the higher dosage.
