Tramadol Use During Pregnancy
Tramadol should be avoided during pregnancy due to risks of embryotoxicity, fetotoxicity, and neonatal withdrawal syndrome. 1
Safety Classification and Risks
Tramadol is classified as FDA Pregnancy Category C, indicating that:
- It has been shown to be embryotoxic and fetotoxic in animal studies 1
- There are no adequate and well-controlled studies in pregnant women 1
- The drug should only be used if potential benefits justify potential risks to the fetus 1
Documented Risks
The FDA drug label specifically notes several concerning findings:
- Animal studies show embryotoxicity and fetotoxicity at maternally toxic doses 1
- Tramadol crosses the placenta with a mean umbilical vein to maternal vein ratio of 0.83 1
- Post-marketing reports include cases of:
- Neonatal seizures
- Neonatal withdrawal syndrome
- Fetal death
- Stillbirth 1
Clinical Considerations
Timing Considerations
Tramadol should particularly be avoided:
- In the first trimester when risk of congenital malformations is greatest 2
- Prior to or during labor unless potential benefits outweigh risks 1
- Chronic use during pregnancy may lead to physical dependence and post-partum withdrawal symptoms in the newborn 1, 3
Neonatal Withdrawal Syndrome
Case reports document neonatal abstinence syndrome after maternal tramadol use:
- Symptoms typically develop within 36 hours after delivery 3
- Treatment with phenobarbital may be required 3
- Hospital observation of the neonate for at least 3 days is recommended if the mother used tramadol during pregnancy 3
Alternative Pain Management Options
For pregnant patients requiring pain management, consider these alternatives with better safety profiles:
First-line agents with established safety records:
For moderate to severe pain requiring opioid therapy:
- Consult with obstetrics and pain management specialists
- Consider short-term use of better-studied opioids if absolutely necessary
Breastfeeding Considerations
Tramadol is also problematic during breastfeeding:
- It is excreted in breast milk 1
- The FDA issued a warning against taking tramadol while breastfeeding 2
- Safety in infants and newborns has not been studied 1
- Following a single IV 100 mg dose, 0.1% of the maternal dose is excreted in breast milk within 16 hours 1
Key Takeaways
- Tramadol should be avoided during pregnancy unless absolutely necessary
- The risks include embryotoxicity, fetotoxicity, neonatal withdrawal syndrome, and potential fetal death
- If used during pregnancy, plan for hospital delivery and extended neonatal observation
- Alternative pain management options with better safety profiles should be considered
- Tramadol is also not recommended during breastfeeding
