Pregnancy Class Darvocet

Darvocet® (propoxyphene/acetaminophen) is a prescription pain reliever that may not be safe for pregnant women.
 
Most medications are assigned to a pregnancy class. Darvocet does not actually have an FDA-assigned pregnancy rating, as it was approved prior to the current pregnancy rating system. However, other trustworthy sources have assigned Darvocet a Category C rating (for short-term use) or a Category D rating (for prolonged use).
 
Various birth defects have been reported possibly due to Darvocet, but it is impossible to tell for sure if these problems were actually caused by Darvocet, other medications that were taken, or simply coincidence. One study suggests a possible link between Darvocet and the following birth defects:
 
  • Microcephaly (abnormally small head)
  • Cataracts
  • Non-cancerous tumors
  • Clubfoot
  • Patent ductus arteriosus (a heart defect).
  •  
Other studies are necessary to confirm these findings before it can be said with certainty that Darvocet actually causes these problems. As is usually the case, it is assumed that the risk for birth defects due to Darvocet is greatest when the medication is taken early in pregnancy.
