Drug Interactions With Propoxyphene/Acetaminophen

There are a number of medications that may cause propoxyphene/acetaminophen drug interactions, including carbamazepine, monoamine oxidase inhibitors, and certain beta blockers. These interactions could increase the drug levels in your blood, perhaps increasing your risk of side effects. To help prevent these drug interactions, make sure to tell your healthcare provider about all other medications you are taking before using the pain reliever.

Propoxyphene/Acetaminophen Interactions: An Overview

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.
