Precautions and Warnings With Propoxyphene/Acetaminophen
If you are about to take propoxyphene/acetaminophen, it's important to know the precautions and warnings with this drug. For example, this medication isn't right for everyone. Since propoxyphene/acetaminophen contains a narcotic and has the potential to be abused, it is not recommended for people who have a history of alcohol or drug dependence. An accidental or intentional overdose can be fatal within 15 minutes.
In November 2010, the United States Food and Drug Administration (FDA) withdrew all medications that contain propoxyphene from the market. It has been determined that the risks of propoxyphene outweigh the possible benefits. In particular, the FDA was concerned about the drug's ability to cause serious changes in the heart rhythm, even at normal doses. Pharmacies will no longer sell this medication, and people who take it should stop and ask their healthcare provider for a more suitable pain medication.
