Precautions and Warnings With Propoxyphene
Propoxyphene may cause low blood pressure, irregular breathing, and other potentially serious complications.

Other precautions and warnings with propoxyphene include potential drug interactions and possible dangers of taking it while pregnant or breastfeeding.
What Should I Tell My Healthcare Provider Before Taking Propoxyphene?
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.
